Does fish oil cause blood thinning?

Omega-3 fatty acids from fish oil have the capacity to "thin the blood." In reality, omega-3s exert a mild platelet-blocking effect (platelet activation and "clumping" are part of clot formation), while also inhibiting arachidonic acid formation and thromboxane.

But can fish oil cause excessive bleeding?

This question comes up frequently in the office, particularly when my colleagues see the doses of fish oil we use for cardiovascular protection. "Why so much fish oil? That's too much blood thinning!"

The most recent addition to the conversation comes from a Philadelphia experience reported in the American Journal of Cardiology:

Comparison of bleeding complications with omega-3 fatty acids + aspirin + clopidogrel--versus--aspirin + clopidogrel in patients with cardiovascular disease.(Watson et al; Am J Cardiol 2009 Oct 15;104(8):1052-4).

All 364 subjects in the study took aspirin and Plavix (a platelet-inhibiting drug), mostly for coronary disease. Mean dose aspirin = 161 mg/day; mean dose Plavix = 75 mg/day. 182 of the subjects were also taking fish oil, mean dose 3000 mg with unspecified omega-3 content.

During nearly 3 years of observation, there was no excess of bleeding events in the group taking fish oil. (In fact, the group not taking fish oil had more bleeding events, though the difference fell short of achieving statistical significance.) Thus, 3000 mg per day of fish oil appeared to exert no observable increase in risk for bleeding. This is consistent with several other studies, including that including Coumadin (warfarin), with no increased bleeding risk when fish oil is added.

Rather than causing blood thinning, I prefer to think that omega-3 fatty acids from fish oil restore protection from abnormal clotting. Taking omega-3 fatty acids from fish oil simply restores a normal level of omega-3 fatty acids in the blood sufficient to strike a healthy balance between blood "thinning" and healthy blood clotting.

    As a veterinarian I've dispensed fish oil capsules for several years.  Some owners give so many that the dogs smell 'fishy' when seen for routine care.  The owner doesn't smell it since they're with the dog a lot.  The coats are gorgeous, something that doesn't often happen in Wyoming at 7000ft altitude.

    Due to an afib episode a couple of years ago, I was taking 20 mg of warfarin per day, plus around 5000 mg of EPA+DHA, and never had bleeding issues.  

    My INR was always a stable 2.0.

    As I've not had an afib reoccurrence, I've replaced the 20mg coumadin with 325mg aspirin daily, and still take around 5000 mg EPA+DHA.  No bleeding issues with that combo either.

    Glad this topic came up.
    Over the last 5 years, I've had to periodically eliminate my fish oil intake as I would start to bruise badly. My internist said she has seen this occasionally with fish oil and called it "capillary fragility." I bruise easily anyway, but it would really get bad with fish oil. So there must be some quality in fish oil that influences this.

    Then about 6 months ago I started a strong supplement change to help with my low bone density--already taking magnesium and calcium but added:
    Boron, K2, silica,pomegrantate juice, and BIG increase in vitamin D.
    I also increased omegas to 3,000 a day which I was not able to tolerate before.

    It has been over 4 months since I have had ANY bruise---which is just unheard of for me. I usually have 3-4 different bruises on arms/legs. So something in these supplements  strengthened my capillaries I guess, and I can now take high fish oil doses!
    Anyone else had a bruising problem with fish oil?

  • Dr. William Davis

    10/27/2009 11:04:59 AM |

    Hi, Catherine--

    Fascinating observation!

    I'll bet it has something to do with the vitamin D, more than anything else. Vitamin D seems to strengthen structural tissues in bones, muscle, heart valves, and perhaps capillaries and other small blood vessels.

    Several years ago I bruised easily for a while and attributed it to taking garlic supplements daily.  I started taking Vit C and the bruising stopped.  I don't think it had to do with fish oil (in my case); I don't think I was taking fish oil at the time.

  • Daniel

    10/27/2009 9:37:33 PM |

    I too achieve rapid blood thinning when taking 2400mg of EPA/DHA per day. That's only 4 pharmaceutical grade capsules. Even after my vitamin d levels were normalized I still got bruising.

    I now take Vitamin K2 (MK-7 natto extract) twice a week and it's allowed me to bump my EPA/DHA up to 3600mg with no ill effects or bruising.

    It was either supplement or eat a lot of aged cheese, they both seemed to do the trick in my particular case.

    Thank you for sharing this study with us.  It helps clarify whether there is a risk for blood thinning from taking fish oils.  This information may help individuals who are taking blood thinning medications and considering adding fish oils to their daily diet.

  • Dave

    10/28/2009 2:22:01 AM |

    Catherine,

    Without a doubt, your cessation of bruising was due to vitamin k2. I routinely take nattokinase, large doses of fish oil, curcumin, and other blood thinning agents, and if I don't take vitamin K2, I will begin bruising. (I also take high doses of Vitamin D). When I take K2, I have absolutely no bruising.

    Vitamin K2 has many clinical trials showing that it helps endothelium  integrity and elasticity.

    Also, grapeseed extract and pine bark extract (specifically oligomeric proanthcyanins) has the same beneficial effect.

  • Catherine

    10/28/2009 4:41:41 PM |

    Daniel,

    That's really interesting! There is a lot of research on K2's effect on strengthening weak bones. Bone fractures go down considerably when high doses of K2 are used (Japan is using K2 as osteoporosis treatment) BUT studies show it needs to be in conjunction with adequate calcium and Vitamin D---they work synergistically for bone strength.  So it makes sense that K2 and D could do the same with strengthening fragile capillaries. I am also taking the M7 natto form.

  • Catherine

    10/29/2009 12:01:36 AM |

    Dave,

    Thanks for sharing your experience with this, you've really confirmed it now for me.  I can't believe I have suffered with this for most of my life with no answers (tried high dose Vit C, grape seed, etc) and now within months on K2, there's no bruising and I can tolerate fish oil. Hope my bones are responding this well!
    This blog is so helpful....

Fish oil for $780 per bottle

Fish oil for $780 per bottle

At prevailing pharmacy prices, one capsule of prescription Lovaza fish oil costs $4.33 each.

Yes, you heard right: $4.33 per capsule.

What do you get for $4.33 per capsule? By omega-3 fatty acid content, you get 842 mg EPA + DHA per capsule.

I can also go to Sam's Club and buy a bottle of their Triple-Strength fish oil with 900 mg omega-3 fatty acids per capsule at $18.99 per bottle of 180 capsules. That comes to 10.5 cents per capsule. That puts the price of fish oil from Sam's Club at 97.6% less cost compared to Lovaza for an equivalent quantity of omega-3 fatty acids.

What if we repriced Sam's Club's Triple-Strength and brought it "in line" with what we pay for Lovaza? That would put the value of one bottle of Sam's Club Triple-Strength fish oil at $780 per bottle.

I take patients off Lovaza every chance I get.

    It's amazing how much some of these companies will try to scam people with 'pharmacy grade' vitamins. It's easy for me to tell how much fish oil is oxidized by taste and how well it works and the best brand I've found is from trader joe's for 8 bucks a bottle. For stuff like vitamin C the process is so simple it's pretty much literally impossible to have any real difference brand to brand aside from how absorbable it is and again it's easy to tell when pills are not absorbing due to how they feel.

    Wow - I'm so surprised that there are worries about a national health care service in the US such as we have in the UK. Here, Lovaza (Omacor) costs the National Health Service £50 for 100 capsules, ie 50p per capsule !

    Of course that's not what patients pay. Patients who are charged prescription charges will pay  Â£7.20 per prescription of 100 capsules, and patients who don't pay prescriptions charges at all (approx 70% of patients), well they don't pay anything for their Lovaza....they have paid in their taxes for it already.

    But to me the biggest surprise is that the pharmacutical company that makes Lovaza charges so much less in the UK than it does in the US !

    It's not really a problem that pharmacy grade fish oil is ridiculously expensive, as long as it's not illegal to sell cheaper fish oils too.

    In Europe, the trend seems to be that supplements are becoming available only in pharmacies, which can then charge extraordinary prices for everything.

    I have moderately high triglycerides at 255. My physician gave me a sample bottle of Lovazza to try which has 28 softgels. I have been taking one softgel a day.

    I have been looking into OTC fish oil supplements. Some are very diluted and some are very concentrated. Most break down the EPA and DHA content while others don't. I created a spreadsheet that collects the EPA and DHA content of several OTC fish oil supplement. In order to make a fair comparison, I adjusted my serving size for each brand name to give me about the same quantity of the essential fatty acids. The prices range from $0.11 per dosage to $1.76 per dosage.

    So once I figured out what's the most cost effective brand to buy now I have to worry and wonder about purity. Am I getting a less refined formula that will have heavy metals, PCBs, and other nasty chemicals? The words "triple distilled" mean nothing to me. I'd like to see "Contains no more than 0.010 PPM of arsenic" or something like that.

    The Lovazza might have the advantage here since the FDA probably won't let poisoned fish oil out. I have no idea what my effective price per dosage is with Lovazza since my sample bottle was free. My company takes a decent chunk of my pay for health care and I rarely use it. Maybe it's time I get my money's worth and get some subsidized Lovazza?

    My one month experiment with Lovaza is over. I received a free sample bottle with 28 capsules last month from my physician. The recommended dosage was four a day but he told me to take one. I did that for one month. My triglycerides went down from 255 to 135 with no significant change in diet. My total cholesterol went down from 221 to 177, and it was all LDL. Unfortunately, my HDL levels stayed almost the same.

    So do I continue with Lovaza and get a prescription or do I get a high quality OTC like Omapure?

    I will see my physician tomorrow.

    Just want to add that Omacor (European Lovaza) costs £2 per day, while Triple Strength Omega 3 from a reputable company costs 12p per day in comparison, for roughly the same amount of EPA and DHA. You just have to take 6 capsules instead of 4.

Let's soak 'em with fish oil

Let's soak 'em with fish oil

If you don't think that charging drug prices for fish oil is wrong, take a look at a letter from an angry Heart Scan Blog reader:


Hello Dr. Davis,

My 44 year old brother had an MI [myocardial infarction, or heart attack] in June. He got pushed around due to "bad government insurance," a state-run program for the "uninsured": government pays 1/3, job pays 1/3, and individual pays 1/3.

What they didn't tell him is that there is no major medical coverage and little to no prescription coverage. We fought for 4 months to get him open heart surgery that the insurance was not going to pay for.

Now, with no assistance, terrible insurance, and no disability he has little to no income. He is a heavy equipment mechanic and is trying to be the "good American"-- take care of his bills, not file bankruptcy, etc.

Anyway, the doctors never seem to pay attention to what they prescribe. Lipitor was not working for him, due to side effects. Now they want to give him Zetia and Lovaza....Zetia at $114, and Lovoza is $169.85! Wow! For dead fish???? I think this is a little fishy! I looked up Lovaza, gee how nice, they will give you a $20 coupon....

Forget it, he can't afford this stuff. So I am enrolling in the Zetia program for him. And trying to get him OTC [over-the-counter] fish oil. The most prevalent fish oil around here (that I take myself is) Omega 3 Fish Oil that has EPA 410mg, DHA 274.

Thanks for your blog. It made me feel better that I wasn't the only one outraged by this stuff. I 've been a nurse for 20 years and it just never seems to get better. Thank you for your wisdom.

Sincerely JP, Tennessee



Had this reader not been aware that her brother could take fish oil as a nutritional supplement, he likely would have been denied the benefit of omega-3 fatty acids in slashing the risk for recurrent cardiovascular events. You and I can buy wonderfully safe and effective fish oil as a nutritional supplement, but there won't be a sexy drug representative to sell it, nor an expensive dinner and payment for a trip to Orlando to hear about it.

    Dr. Davis,

    Your correspondent should tell his brother to ditch the Zetia too. The research makes it clear it does not prevent heart attack and may worsen health. Statins appear to be helpful because of their impact on inflammation, not because they lower LDL cholesterol. Zetia lowers cholesterol in a mechanical way that has no impact on inflammation.

    As an internist not categorically opposed to statins (although I agree with starting with nutrition first, which is why I read this blog), there are generic alternatives for this person's brother. If my patients need Western drugs, I start with cheap generics whenever possible. Zetia has dubious benefits of ANY kind, and costs a fortune. And of course Dr. D is right that there are many cheaper sources of fish oil; I usually point my patients in that direction.

    I often feel "standard" American-style medical practice is intended to waste as much money as possible. People need to be able to trust their docs to execute plans that are not only based on the research evidence, but are cost effective. There is no culture of cost-effective medicine in this country, because health care was defined by the Americans as a for-profit arena.

    Lovaza fills a void created by bad government and insurance policy. According to IRS rules, over the counter supplements cannot be covered by many insurance handlers. My work's HSA is like this. Fish oil / omega-3 is technically considered an over the counter supplement. The folk making Lovaza more than understand the benefits of omega-3 and want to sell it to the folks who want their insurance to pay for it. So they made it into a "drug" and sell it as such. It's a brilliant marketing plan and it seems to be working for them. The sad part is that it is working! It shouldn't! Same thing goes with Lovastatin. Why not take a good red yeast rice? Oh well... you pay for what you don't know.

Interview with world heart scan authority, Dr. John Rumberger

Interview with world heart scan authority, Dr. John Rumberger












Dr. John Rumberger has, from its start, been a good friend of the Track Your Plaque program.

We are very proud to have his friendship. Dr. Rumberger is not only a world-renowned scientist in the world of cardiac imaging and heart scanning, but also a humanitarian and gentleman. From the very first day I met Dr. Rumberger many years ago, when he answered my many silly and naive questions about heart scans, I came to appreciate his deep and genuine interest in improving the world of heart disease detection.

I tracked Dr. Rumberger down from his busy schedule, now on a new project at the Princeton Longevity Center in Princeton, New Jersey.




TYP: Dr. Rumberger, we understand that your career has taken a new direction. Can you tell us about your current project?

Dr. Rumberger: I have not really taken a new direction, but further expanded on my opportunities.

I remain Medical Director of PrevaHealth Wellness Diagnostic Center (formerly Healthwise) in Columbus, Ohio. At that center, we see patients referred by their doctors for further refinement in cardiac risk stratification using heart and body scanning. However, by only doing scans alone there are limited opportunities for me to react in a meaningful way with the individual patients and thus I miss opportunities to do direct one-on-one teaching.

Currently, I spend most of my time in Princeton, NJ as Director of Cardiac Imaging for the Princeton Longevity Center. At the PLC, we perform comprehensive medical examinations along with screening CT scans, blood work, fitness and diet consultation to affect a more thorough one-on-one experience. Each patient then receives a comprehensive de-briefing.

In addition, since I have been involved with cardiac CT for now nearly 24 years, the PLC also affords me an opportunity to develop a CT coronary angiography training program for cardiologists and radiologists (www.cardiaccta.us). Together, these new efforts are merely an extension of my interests in prevention, patient care, and teaching.



TYP: Based on your book, The Way Diet, we understand that you advocate gravitating away from processed foods and incorporating more nuts, monounsaturated oils, lean proteins like fish, and a reduction in processed carbohydrates. You’ve also been a proponent of the Mediterranean diet that demonstrated a dramatic reduction in cardiovascular events in the Lyon Heart Study.

Has your philosophy or practice regarding nutritional strategies evolved or changed in any way since your book was published?

Dr. Rumberger: No, the strategies put forward in The Way Diet have, if anything, been reinforced by further and further research in selecting foods that are naturally high in anti-oxidants with lean sources of protein and reduced intake of processed sugar-containing preparations. The book, however, is what I call a ‘philosophy’ book which looks at three major aspects: proper diet, adequate exercise, and stress management. I also include some recipes which follow the dietary plans, but are done using ingredients that are commonly found in the average home.



TYP: We regard you as the source of much of the wisdom in heart scanning as the basis for early heart disease detection. Much of the original and subsequent scientific data, in fact, bears your name. Can you touch on some of the new directions your research has taken over the past couple of years?

Dr. Rumberger: We have come a long way from the beginning and there is a long way to go to get this incorporated into routine preventive care in the United States.

The most recent research has provided not so much more information as continuing to reinforce the old research. As I always say: if your research continues to show the same thing, then maybe there is a clear pattern here! The biggest challenge is getting this message into the mainstream and also trying to get cardiologists (and internists and, in fact, the general public) away from ‘stenosis’ detection to define the real cause of heart attacks (plaque) and into ‘plaque detection.’ This is where basic heart scanning has the greatest potential to reduce the expanding burden of heart disease.

You may be aware of our SHAPE initiave in which an international group of cardiologists and scientists have advocated getting a heart scan FIRST and then, if abnormal, checking your cholesterol values; rather than using cholesterol (which is valuable, but highly variable in predictive power) to determine who needs medications or further testing. The heart scan can define the current level of plaque and THEN you can determine what to do about it. [See the Track Your Plaque report on the release of the Shape Guidelines at SHAPE Guidelines]



TYP: We understand that you are performing CT coronary angiography in your center. What are your thoughts on the role of CTA in 1) screening for coronary disease, and 2) its role in the diagnostic process?

Dr. Rumberger: CT coronary angiography (CTA) is an incredible method to really define the extent of disease, beyond just coronary calcium. Its role is most appropriate in ruling OUT a significant ‘stenosis’ while really defining the absence or presence (and thus ‘how much’) of plaque. It is the ultimate ‘plaque detector’. CTA is best used in patients who have some symptoms, but in whom the clinician feels may NOT have clear cardiac chest pain. By risk-stratifying using CTA, we also gain information about heart size, heart function, whether there is prior heart damage, as well as other important information. This then becomes a very universal means to risk-stratifying individuals.



TYP: Thanks for your wonderful insights, Dr. Rumberger! We look forward to hearing about your future projects and research directions.

    In addition, since I have been involved with cardiac CT for now nearly 24 years, the PLC also affords me an opportunity to develop a CT coronary angiography training program for cardiologists and radiologists (www.cardiaccta.us). Together, these new efforts are merely an extension of my interests in prevention, patient care, and teaching.

No wonder nobody talks about real prevention

No wonder nobody talks about real prevention

Take a look at this eye-opening statement taken from a well-written NY Times article about Dr. Arthur Agatston, the South Beach Diet and now South Beach Heart Program books:


'We have made major improvements in prevention,” Dr. Gregg W. Stone, the director of cardiovascular research at Columbia University, says. “But it’s difficult. It takes frequent visits, a close relationship between a physician and a patient and a very committed patient.'

Which is exactly the atmosphere Dr. Agatston’s practice tries to create. Nurses there give patients specific cholesterol goals to meet and help them deal with the side effects of the drugs they are taking. A nutritionist, Marie Almon, meets with patients frequently enough to discuss real-life issues like how to stick to a high-fiber Mediterranean diet even on a cruise or a business trip.

There is only one problem with this shining example of a medical practice: it is losing money.



From NY Times, January 24, 2007. What’s a Pound of Prevention Really Worth? (Find the full text at http://www.nytimes.com/2007/01/24/business/24leonhardt.html?ex=1172379600&en=4268a738e82857da&ei=5070.)

It gets at one of the fundamental reasons why your cardiologist will probably never talk to you about an intense approach to prevention: it doesn't pay. Because John Q. Cardiologist focuses, instead, on how to increase procedural volume, train how to put in the next best defibrillator, etc., there is little consciousness about preventive issues. Just the simple matter of taking fish oil causes their eyes to glaze over.

That's why the Track Your Plaque program exists: it is a portal for the kind of information you cannot get. Of course, you could read all the scientific studies, attempt years of trial and error, and try to gain a sense of how to do this yourself. Or you could follow this program. We are proud to not worry about generating procedural profits. We ar unbiased by drug or medical device money. We say exactly what we mean.

By the way, we are on a current push to really "beef-up" our online discussions via real-time chat. Long-term, we'd like to be able to offer chat with our staff many hours every day. Be patient. It will happen, but not today.

Roger's near-miss CT angiogram experience

Roger's near-miss CT angiogram experience

Heart Scan Blog reader, Roger, described his near-miss experience with CT coronary angiograms.

Hoping to obtain just a simple CT heart scan, he was bullied to get a CT coronary angiogram instead. Roger held strong and just asked for the test that we all should be having, a CT heart scan.


I posted yesterday that I was about to have my first CT heart scan...well, it was an interesting experience for reasons I coudn't possibly have anticipated. Dr. Davis has commented in the past on the confusion in the media about the difference between a CT calcium score scan, and a CT angiography, the latter requiring a far higher dose of radiation. I assumed this was a source of confusion only among patients and lay folks, but, lo and behold, I discovered today that doctors--or at least their helpers--can be just as confused.

Here's my story:

After checking in, I asked the receptionist to see if she had any information on whether my medical insurance was covering the scan. She called someone, and I heard her say over the phone, "He's here for a CT angiogram." At that point my ears perked up. I explained I wasn't here for a CT angiogram, only a regular CT scan. "Well, do you want to call your doctor and talk about this?" she asked. No, I said, I would like to ask one of their folks to verify exactly what test my doctor had ordered. As luck would have it, the technician was walking by at that point. "Is this a CT angiogram?" the receptionist asked. "No, it's just a CT calcium score scan" was the reply. But apparently the technician had been unclear herself, and had called my doctor just to verify. In other words, the "default" procedure they were accustomed to doing at this august Houston vascular clinic was a CT angiogram.

In fact, my appointment was even listed on their calendar as a "CT angiogram." For all I know, my insurance will be billed for the same. Later, during the procedure, the technician acted surprised I wasn't doing the "full test." I explained I had minimal risk factors (actually only one, an HDL of 34 a couple of years ago, which has since been raised to 50 partly as a result of taking advice from this site), but that my doctor was progressive (he is an MD for the Houston Astros) and thought it was a good idea since there is heart disease in my immediate family. My doctor did indeed prescribe only a CT calcium score scan, but it seems to have been an order that this clinic, at least, wasn't all that used to seeing.

So, I guess the message is: we have a lot of educating to do. Had I not been a faithful reader of these pages, I certainly wouldn't have known what kind of test I was about to get, or what questions to ask!

As for the heart scan itself, a piece of cake. If you can hold your breath, you can take this test. Just be sure it is the right one!



Why the "push" towards CT coronary angiograms and not "just" a CT heart scan? Well, I know it's shocking but it's . . . money!

CT coronary angiograms yield around $1800-$4000 per test. CT heart scans yield somewhere around $200. Though the scan center support staff might not care too much about the money themselves, their administrators likely make the cost distinctions clear to them.

Another reason: Most scan center staff, ironically, don't understand what a heart scan means, nor do they understand how it might serve to launch a program of prevention. They do understand that severe blockage by CT angiogram "needs" to be stented or bypassed. So they push patients towards things they understand.

Nobody makes money from CT heart scans, just as nobody makes money from a mammogram. Heart scans also don't lead to heroic, "lifesaving" procedures. They just lead to this sleepy, unexciting, inexpensive thing called prevention.

    -very few, if any grains (whole or refined)
    -very low sugar and starch consumption (low carb)
    -pastured red meat several times a week (bison, beef, or pork)  with normal ferritin level
    -high saturated fat consumption (grassfed butter, coconut oil, home-render lard)
    -whole fat dairy (incl raw whole milk and raw milk aged cheese)
    -no attempt to artificially increase fiber, though there's probably a fair amount of fiber in the ample fresh non-starchy veggies I consume
    -2 to 3 "backyard" eggs cooked in ample butter nearly daily for breakfast

    Rogers experience brought back an unpleasant near miss CT Angiogram memory of an episode that I had while being in the hospital 5 years ago. I was  brought in with congestive heart failure-EF 20/25,  Now Don't think you are soon to lose a faithful reader, my EF is now 45/50, due to Aranesp injections, that I am doing exceptionally well on.  My anemia is now under fabulous control.
    But, I digress, one day while in the hospital a beautiful young lady with long flowing hair wearing a white coat and stethoscope came in to see me and identified her self as the cardiologist assistant. She quickly started to promote me to have an angiogram.  I refused. The hospital cardiologist came to see me and I told him not to send me any more sales reps. (he must have learned this technique from big Pharma with all their beautiful drug sales reps). I never did have that apparently unnecessary needless invasive procedure done.  Guess what?, I lived to tell the story.

    One morning last year, I drank way too much strong tea. A few hours later, I had chest pains and tachycardia. I had forgotten about the tea, which with hindsight  was the obvious cause, and I went to an emergency room.

    By the time I got there, the pain had gone, and I should never have stepped into the ER waiting room.

    As soon as they got their hands on me, they wouldn't let me go, claiming that insurance wouldn't pay if I left against doctors' orders. They quickly ran up any thousands of dollars of expensive tests, all of which came back fine.

    They were very unhappy that I refused a coronary artery stent.

    My ejection fraction was 65.

    "A new study shows 30% drop in mortality from CD"

    Yes, modern medicine "saves" more people all the time.  

    But is the *incidence" of CD dropping? or is medicine just getting better at treatment.  I want to avoid CD, not just be saved from it.

    I used to be a strong believer that the US needed a universal medical care system similar to Canada and the UK.  Now that I have had a closer look at the UK's system over the last 14 years (in-laws are there) and have experienced the profound lack of primary prevention under a US HMO system (healthcare rationing), I'm not-so-sure.  

    Sure, we are a rich nation and we should be able to afford decent healthcare for everyone.  The current system is for haves and have-nots with the in-betweens really getting pinched.  And furthermore, the haves don't get nearly the quality of care that they pay through the nose for anyway (though many don't realize it).  

    But I can't see how turning over the decisions to government is going to be any better than it has been to turn over decisions to HMP insurance companies and accountants.  In fact, it could get worse.  Especially since government has turned into the handmaiden for special interests.  As much as I think it should happen, I have a hard time getting behind the proposals.  Be careful what you wish for, you might get it.

Lovaza vs fish oil supplements?

Lovaza vs fish oil supplements?

Lovaza is the FDA-approved form of fish oil that is available only by prescription. It contains 842 mg of the omega-3 fatty acids, EPA and DHA, per capsule.

The FDA application for Lovaza is viewable here on the FDA website. Interestingly, while there is plenty of the usual regulatory gobbledy-gook about toxicology, dose escalation, and efficacy in the extensive documentation, there is little said about the issue of contamination.

In other words, critics of nutritional supplement fish oil harp on the possibility of contamination with mercury and pesticide residues, like dioxin and PCBs (polychlorinated biphenyls). Yet there is virtually nothing about these same issues in the FDA application for Lovaza.

Let's take a look at a sample over-the-counter fish oil product. Our friends at PharmaNutrients (a new Track Your Plaque partner for nutritional supplements) have a fish oil product called PharmaNutrients" Cardio. Here's an independent analysis of the Cardio product (per 1000 mg fish oil capsule):

EPA content: 566.1 mg
DHA content: 216.6 mg
(Total EPA + DHA 782.7 mg)

Cardio passed all tests for peroxides, PCBs, dioxin, furans, dioxin-like PCBs, and heavy metals (arsenic, cadmium, lead, mercury) using criteria at least 60% more stringent than European Commission (EC) standards (EC standard <2 picograms/gm for dioxins and furans, PharmaNutrients <1 picograms/gm; EC standard <10 picograms/gm for dioxin-like PCBs, PharmaNutrients <3 picograms/gm). PCBs levels in particular are less than 0.009 ppm, 90% below the industry-wide purity standard of 0.09 ppm. Likewise, mercury is >90% lower than European Commission standards.

In other words, this over-the-counter "pharmaceutical grade" fish oil has virtually nothing but omega-3 fatty acids.

Interestingly, the PharmaNutrients fish oil capsule also contains the third omega-3 fatty acid, docosapentaenoic acid (DPA), a neglected form that some authorities have proposed has superior cardiovascular protective properties over eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). If DPA is included in the analysis, PharmaNutrient's Cardio contains a total of 900 mg omega-3 fatty acids per capsule.

At some point, I'd like to see a head-to-head comparison not just on purity grounds, since I am convinced that high-quality products like Cardio can match or exceed the purity of prescription fish oil, but on efficacy in raising omega-3 blood levels, the omega-3 index. (The omega-3 index is a predictor of heart attack and sudden cardiac death--the higher, the better.) My prediction: High-quality fish oil supplements will match or exceed prescription fish oil.

    Yes, quality and contamination of fish oil IS important.
    I have heard that KRILL oil is superior to fish oil on all fronts. It supposedly has much less contamination than fish oil, better bioavailability (bound to phospholipids) and additional ingredients, i.e. Zeaxanthin (important for retinal health).
    Can you comment on this?

    After my sample bottle of Lovaza from my physician was done, I switched over to Trader Joe's brand. It's really cheap at $10 per bottle and the EPA/DHA concentration is 50%. I take about 5 to 6 capsules a day and my last triglyceride in December was 109 (down from 255). I also tried Omapure too but it's pretty expensive. Omapure's advantage over the TJ stuff is that it is independently tested by IFOS. Who knows where TJ's stuff comes from? I tried the Spring Valley (or is it Nature Made) brand from Walmart. Pure nastiness! Stay away from those yellow bottles.

    I bet some MBA guy dreamed up Lovaza at a brainstorming session intended to come up with ideas to boost sales in a sagging economy.

    Dr. Davis, your EPA/DHA content listings in the post seem to contradict the label on the bottle. The bottle claims 2 capsules contain 1100 mg of EPA and 500 mg of DHA. That would translate to 550 mg of EPA and 250 mg of DHA. What am I missing?

    I always suggest opening fish oil capsules once in a while to see if the oil is stinky.  That is the advantage of liquid oils is that you can smell and taste them.  One of my nurses opened a Lovaza capsule and told me it made her gag it was so fishy.  The antioxidant used in Lovaza is hydrogenated soybean oil!!.  One of my patients who is sensitive to soy reacted to Lovaza with a rash.

    1/27/2010 7:12:37 PM |

    Dr. Davis,

    The following question was somewhat inspired by this post, although it relates more specifically to seafood consumption.

    A few months back, I started ordering seafood from Vital Choice. According to the Vital Choice website, their Albacore tuna has 0.05 ppm of methyl mercury and that number falls to 0.03 ppm for their sockeye salmon (which Is what I typically order).

    http://www.vitalchoice.com/uploads/Merc%20Comp%204_06.pdf

    I often hear a general guideline that 2 servings of non-predatory fish (preferably wild caught and definitely not farm-raised) is generally accepted as safe, or at least minimally risky, and that this is likely a good guideline for everyone, but especially pregnant women and children.

    However, when I would place a sizable order, I would find myself serving it at least 2, and often up to 4 times per week. So that would be up to 4 servings of roughly 4-6 ounces of fish during some weeks that I would serve to my wife and for myself.

    In your opinion, should we cut back to 2 or fewer servings or are the levels listed by Vital Choice low enough to skirt potential issues?

    NOTE: the only seafood I eat is what I purchase from Vital Choice, so that I know the source. While the methylmercury is a focus, I am also curious if this level of consumption is also risky in terms of PCB’s and dioxins. It’s frustrating to realize that there will always be some measure of inherent risk.

    My wife and I aren’t eating this in place of supplementing with a purified fish oil supplement, we simply add this to it, so on days when we eat fish we lower our dose a bit and on days we don’t, we bump up that dosage. Our primary reason for consuming it is the delicious taste, along with the “bonuses” of protein, astaxanthin, vitamin D, and omega 3’s that come along for the ride.

    On one final note, I am also curious if the selenium content of the seafood is at all protective against methylmercury, particularly at these lower levels found in the Vital Choice fish. I’ve heard selenium has the potential to chelate methylmercury, but I am uncertain if this lessens the risk to any noteworthy degree, that is if I am not misinformed to begin with on this front.

    One concern with all over the counter supplements, is that they are not continually tested. The test is applied to one batch of the supplement, perhaps years earlier.

    As a result, when random samples are sent to labs contamination is often found in supplements that claim to be free of contaminants.

    I don't know if there is better supervision in the case of products sold as pharamceuticals, but I think we have to be very careful in accepting purity claims from any company operating in the Wild West unregulated supplement market. The track record when these products are spot checked is terrible.

    Ren-

    While I think that krill oil is a fascinating product that we have used, I feel that the manufacturer's over-the-top marketing has clouded its real value. It is absurd to propose that krill oil be used as a replacement for fish oil until we have 1) confident data on omega-3 RBC levels, and 2) outcome data.

    In other words, fish oil has been shown to dramatically reduce cardiovascular risk. Krill doesn't yet enjoy this advantage. While it might be true, it is premature to make claims to that effect.

    Hi, Jenny-

    Sorry, but I've got to disagree with you on this one.

    Take a look, for instance, at the two analyses by Consumer Lab (www.consumerlab.com). 77 fish oil products tested; 2 flunked due to oxidative byproducts. None flunked due to mercury, dioxin, PCBs, or related compounds. This has held true in Consumer Report and several other analyses.

    Frankly, I wouldn't be caught dead taking Lovaza, because I care too much about healthcare costs. Why stick it to other people when I can buy fish oil for a lot less?

    I strongly agree that Lovaza is a rip-off.

    But unfortunately, the brand it's being compared to (PharmaNutrients) is a rip-off too. Once upon a time you were mentioning the benefits of Costco brand fish oil, or cheaper alternatives. $30/bottle isn't really cheap, when anyone can go to iHerb and get much better deals.

    Jarrow Formulas, EPA-DHA Balance, 630mg/Gel -- $13 for 120 softgels. Or 240 softgels for $23.

    PharmaNutrients vitamin D is another ripoff. $20 for 120 gels, 2000IU. I can get 120 gels of 5000IU for around $8 at iHerb (Now brand).

    I question why you decided to choose PharmaNutrients as a partner, when they are clearly so overpriced.

Could be the artery-clogging fats found in beef and bacon. Or it could be that both red- and processed-meat eaters consume less body-friendly foods like whole grains, fruit, and veggies. In fact, other research shows that vegetarians fare best when it comes to heart disease mortality."

    The last line is interesting.

    I often hear a general guideline that 2 servings of non-predatory fish (preferably wild caught and definitely not farm-raised) is generally accepted as safe, or at least minimally risky, and that this is likely a good guideline for everyone, but especially pregnant women and children.

    I also take OMAPURE.  It's almost as pure as LOVAZA (70% vs. 84%) but is tested by third party IFOS and has no PCBs and mercury.  I wish OMAPURE was cheaper but it is still less than Sears Fish Oil and much much less than the rip off Lovaza!  Lovaza is such a joke - should be exposed on 60 minutes.

    This Pharmatrend Cardio Formula is ALMOST as concentrated as Lovaza.  Lovaza is about $150 for 120 capsules (a 1 month supply for a the FDA approved 4g/day dose for triglyceride reduction).  The Pharmatrend is $30 + shipping for a 15 capsule package!  That's almost a 4 day supply for triglyceride reduction.  So, it's $30 x 7.5 for a month supply.  That's $225/month!  However you slice it, it's actually less expensive to go with the prescription.  If you are covered by insurance, you will only come out of pocket at around $30-$40 per month for the FDA approved prescription.  Don't let "supplement" make you think it's better or less expensive

    Lovaza is an ethyl ester of EPA not the actual EPA itself. It also includes DHA. However, the ester is supposed to significantly lower blood pressure and cholesterol far more than just plain old normal omega 3.

    What really upsets me is that physician only supplement companies with high quality supplements and processing standards that meet or exceed GSK's are NOT allowed to make the claim that Omega 3's helps lower triglycerides. Simply because the FDA has not evaluated their product. Really?

    The FDA is a joke. They approve unsafe drugs based on studies given to them from drug companies. Since the FDA does not require them to provide all of their research, drug companies are allowed to show them their studies that had positive results with little side effects, leaving out the incriminating studies. Some drugs are "fast tracked" through the approval process are then later pulled from the market due to a high number of deaths and side effects. If you think that the FDA protects us...think again.

    Also note, that a majority of studies are only done on men. Women are excluded due to the risk of pregnancy and drugs are NOT tested on pregnant women in a lab. They use animals for this. While we are biologically similar to rats, we are NOT the same. But nevertheless there are many "approved" drugs that are deemed safe for pregnant women and are only restricted later after clinical usage has shown to cause birth defects.

    When a drug is removed from the market everyone is upset at the drug companies. I say, stop blaming the drug companies for being what they are and are expected to be. How about we start blaming the FDA?! Let's hold them accountable for their actions. Suing the drug companies it ineffective. No, they don't want to lose money but let's face it...they don't won't go bankrupt and often settle. People need to wake up...just because something is FDA approved, does NOT make it safe!

    Sorry to rant...but this really irks me.

    You guys are all missing the point entirely. As can easily be seen from the commercial, Lovaza is manufactured in the future from a lab at the bottom of the ocean.  It requires a prescription because it must be shipped from the future to the present, which you can imagine is quite expensive (and dangerous).  The FDA regulates this process of transporting the drug through time.  The dietary supplement formulations of fish oil are actually smuggled through the time rift by rebels similar to those depicted in the Mad Max movies, starring Mel Gibson, thus explaining their cheaper price tag.

    @ safe supplements
    I used to be allergic to fish.
    I couldn't eat fish 2 days running because if I did I'd have a severe sore throat.
    I found raising my anti-inflammatory status with omega 3, vitamin d and magnesium has eliminated my tendency to get allergic reactions to fish or anything else. So now I don't get hay fever either. It's now been some years since I last used an anti histamine.
    Some fish allergic people may find Krill oil is less likely to cause a reaction but be aware some Krill oil capsules also contain fish oil.
    There are also omega 3 formulations from algal-docosahexaenoic acid: effects on triglyceride levels and other cardiovascular risk factors. that you may want to consider but they are a lot more expensive when considering the amounts required to be effective.

    for years the fish oil products that we bought in vitamins stores contained a statement that " The FDA has not evaluated these statments". all of a sudden lovaza comes on the scene & its nowe okay. they say lovaza is purified. This raises the question that the FDA either is lying to us now or they were letting us be pisioned before. which one is it? the FDA in the most corrupt agency of the federal government. ask yourself this question. did you ever hear of restless leg syndrome until the FDA approve a prescription medication for it? if the drug companies pay the right people they can get anything approved.

Increased blood calcium and vitamin D

Increased blood calcium and vitamin D

Conventional advice tells us to supplement calcium, 1200 mg per day, to preserve bone health and reduce blood pressure.

Here's a curious observation I've now witnessed a number of times: Some people who supplement this dose of calcium while also supplementing vitamin D sufficient to increase 25-hydroxy vitamin D blood levels to 60-70 ng/ml develop abnormally high levels of blood calcium, hypercalcemia.

This makes sense when you realize that intestinal absorption of calcium doubles or quadruples when vitamin D approaches desirable levels. Full restoration of vitamin D therefore causes a large quantity of calcium to be absorbed, more than you may need. In addition, two studies from New Zealand suggest that 1200-1300 mg calcium with vitamin D per day doubles heart attack risk.

We have 20 years of clinical studies demonstrating the very small benefits of supplementing calcium to stop or slow the deterioration of bone density (osteopenia, osteoporosis). These studies were performed with no vitamin D or with trivial doses, too small to make a difference. I believe those data have been made irrelevant in the modern age in which we "normalize" vitamin D.

Should hypercalcemia develop, it is not good for you. Over long periods of time, abnormal calcium deposition can occur, leading to kidney stones, atherosclerosis, and arthritis.

Until we have clarification on this issue, I have been advising patients to take no more than 600 mg calcium supplements per day. I suspect, however, that the vast majority of us require no calcium at all, provided an overall healthy diet is followed, especially one that does not leach out bone calcium. This means no foods like those made with wheat or containing powerful acids, such as those in carbonated drinks.

    Sometimes I think that the RDAs only apply to the current high refined carb, nutrient depleting diet most americans eat.  

    This is just more proof that the current calcium "requirements" are overstated and probably intended to market dairy products or calcium fortified processed foods.

    I always thought the recommendations for supplementing with calcium were probably wrong.  I've heard that Americans eat more calcium-rich foods and supplement with more calcium than other Western countries, but yet suffer from the highest amount of osteoporosis/osteopenia.  

    This wouldn't surprise me, given the importance of having the right amounts of calcium, Vitamin D, and Vitamin K2.  I've seen other doctors/researchers recommend that Vitamin D always be taken in connection with sufficient intake of Vitamin K2 to help prevent hypercalcemia.  I do not supplement with calcium, but I do supplement with D3 and K2 and have had no problems

    1) It would seem that anyone speaking of vitamin D, is being a little misleading as we should most likely be talking about D-2 or D-3. Or never talking about D-2 and always about D-3 as it is the more bio-active.
    2) Increase K-2 to take care of the D-3 / calcium problem.
    3) Blood tests to keep track of all three of them.

    If you are eating a classic low carb diet and eating cheese rather than meat for much of your protein your calcium intake can get high pretty fast.

    We usually recommend that individuals stop taking a calcium supplement once they've reached the target D level (70-90 ng/mL).

    We always draw a serum calcium with a 25(OH) level.

    Detected several cancers in our patients this way (hypercalcemic prior to starting D supplementation).

    Also, I'm about 8 months pregnant with our first child and you think cardiology is behind the times with Vitamin D, try OB! They're living in the dark ages.

    Fortunately my OB is more versed than most and the fact that I take 10,000 IU daily doesn't make him too uncomfortable (obviously not since he didn't offer to check my D level...I had to ask for it).

    I'm also taking 500 mg QD of elemental magnesium (no preeclampsia for me) and (when I remember), 12.5 mg of Iodoral/week (I worry about taking it everyday due to potential for "heavy metal dumping" since I wasn't routinely taking it prior to pregnancy).

    I still take a pre-natal, but I worry more about not taking the other supplements more than i worry about missing a dose of the pre-natal.

    Thanks for all you continue to do in healthcare!

    I would agree that we probably need no dairy based calcium at all, since it is only necessary at birth through mother's milk.
    Even so, I do like my dairy products in moderation so that's all I take - no additional calcium supplements; and my blood calcium level and bone density has benefited from just D on top.

    while current blood levels of D3 may appear to be inadequate, there is no science to demonstrate what the higher levels shuld be.  While a blood level of 60 coming from the sun may be wonderful, there are no studies, let alone ones of any duration, that show that supplementing with large doses of D3 to get to a 60 level do not pose any negative health consequences.  As we have learned with other vitamin supplementation, more is not always better; adverse consequences can arise, and there is not always a way to detect them such as blood calcium levels.  Caution should be the watchword.

    Hi, Jessica--

    I think that you and your group are managing the calcium/vit D issue the right way.

    Unfortunately, some people are wrongly interpreting this to mean that vitamin D causes hypercalcemia. It simply means that calcium is unnecessary when D is restored.

    Thankfully, your situation is the exception. Most people maintain normal calcium levels even while consuming dairy and other calcium-rich foods.

    Several responders here make the point about magnesium, which I agree with. Have you addressed magnesium? Magnesium deficiency is exceptionally common, since it has been taken out of most drinking water.

    I noticed that a study this week found a correlation between very high vitamin D levels and increased risk of pancreatic cancer.

    Cited are NOT very high levels! The claim is higher rates of pancreatic cancers with >100 nmol/ml - which translates into 40 ng/ml, a level considerably lower than the one recommended here by Dr. Davis (~60-70 ng/ml if I remember correctly). Another claim is NO difference in rates of several other cancers across a large range of 25(OH)D concentrations.

    Peter's comment above led me to read the newswire report referred to.

    This study was trying to establish any epidemiological association of increased levels of Vit D with reduced incidences of various cancers. No such associations were observed. Rather in the case of pancreatic cancer only, it was observed that when the  level of Vitamin D was GREATER than 100 nmol per litre, there was higher incidence of this disease. Another way of looking at this observation is that at levels below 100 nmol per litre there was no association of pancreatic cancer with levels of Vit D LOWER than 100 nmol per litre.

    As far as cancers are concerned there is no point in considering Vit D status as long as it below 100 nmol per litre.

    6/23/2010 10:07:09 PM |

    This is timely. I just had blood work done recently and my Dr.'s staff ordered the wrong test. Instead of measuring D3, they measured D2 calcitriol. I don't know what to make of the result: 120.8 pg/mL on a scale of 10.0-75.0. It's extremely high.  The last time I had my vitamin D3 tested, it was 59.2 ng/mL on a scale of 32-100.
    FWIW, I follow a low carbohydrate Paleo diet and consume very little dairy. I do take a multivitamin 3-5 days per week, but it only provides 300 mg of calcium (along with 210 mg of magnesium). I also take 500 mg of magnesium citrate every evening.
    I'd sure like to know what to make of this.

    @ LeonRover
    The information on pancreatic cancer & vitamin D status comes from Finland

    The further from the equator the greater the swing from high to low status. To have a good shower requires tight regulation of both hot and cold water supplies and a reserve store of both hot and cold supply so neither ever runs out.

    Vieth explains in this paper.
    How to Optimize Vitamin D Supplementation to Prevent Cancer

    In the same way fluctuating concentrations of 25(OH)D may also be a problem, Regions at high latitude or with low environmental
    ultraviolet light can be associated with the greater risks reported for prostate and pancreatic cancers. At temperate latitudes, higher summertime 25(OH)D levels are followed by sharper declines in 25(OH)D, causing inappropriately low 1-hydroxylase and high 24-hydroxylase, resulting in tissue 1,25(OH)2D below its ideal set-point.

    The answer is to keep levels BOTH HIGH and STABLE.
    Humans only build a stored reserve of D3 in tissue above 40ng/ml = 100nmol/l. Only around 60ng/ml are there sufficient D3 reserves for lactating mothers to pass to babies in breast milk. At latitude 32 it takes modern women 6400iu/daily/D3 to provide naturally replete vitamin D breast milk.

    Thanks Ted. That clarifies the role of calcitriol, but I am still wondering why my level measured so high, if even transiently.

    I'm anonymous from above who talked about kidney stones and blood in my urine.

    I had the CT scan done yesterday. I have stones, one of them a whopping 1.4 cm.  

    Be careful people.

    (I am a different Catherine than the one above with tachycardia)

    For years because I had osteopenia, I was advised to take loads of calcium.  Later they told us to add vitamin D with it.  I am now FULL of calcium deposits all over my body.

    A year ago, Dr. Davis advised me to try magnesium for a bad arrhythmia problem, and it not only quickly cured my arrhythmia, insomnia, and RLS, but I have much less grinding sounds and arthritis pain. I was the poster girl for magnesium deficiency and no one except Dr. Davis even mentioned trying it.

    I think along with K2, magnesium is of upmost importance to balance the D and calcium. I only take 500 mg a day now since I don't consume dairy, but after this article, I may totally stop supplementing any calcium and let the K2 and magnesium perhaps reduce some of the deposits..

    @Mike -- I have the same issue/question.  My 25 OH was 62 but the 125 test was sky high.  My serium calcium was normal.  I wonder if Holick's new book gives detailed info on how to interpret lab tests.  His first book just said that the correcxt test is the 25 OH but didn't explain if there is any danger is a sky high 125.

    Vitamin D3:

    NOW Vitamin D softgels supply this key vitamin in a highly-absorbable liquid softgel form. Vitamin D is normally obtained from the diet or produced by the skin from the ultraviolet energy of the sun. However, it is not abundant in food. As more people avoid sun exposure, Vitamin D supplementation becomes even more necessary to ensure that your body receives an adequate supply. Vitamin D3 on discount at NutroVita.com.

    UK readers need to be aware that estimated shipping cost to UK from Nutrovita = $26.50
    whereas
    Item cost IHERB= $4.96 + International Airmail = $4.00
    If you haven't used IHERB before code WAB666 saves $5.
    Remember UK customs apply VAT on orders £18 and above + UK PO charge £8 handling fee so I make orders up to around £17.50 before shipping to avoid that happening.

    Dr. Davis,
    Since increasing my Vitamin D, Magesium and Melatonin I suddenly have very brittle, splitting fingernails.  Any idea which if any of these caused this?  Any suggestions?
    Thanks

    Love your blog!!!!!

    Chances are the calcium supplement you are taking now is a rock source of calcium. The label will say "calcium carbonate", which is nothing more than limestone. AlgaeCal Plus contains an organic, plant-sourced calcium form derived from a unique South American marine algae called Algas Calcareasâ„¢.

    think one of the greatest hurdles is overcoming misconceptions in the minds of regulators, doctors and patients alike. I just returned from a trip to Germany and colleagues there are amused about America's 3rd World-like medical records situation

    I have celiac disease and osteopenia in my spine and no bone loss in my hips. I have a strong family history of osteoporosis as well.

    Because my calcium intake is less than or equal to 500 mg I take:

    600 mg calcium citrate at two seperate meals

    1200 IU's D3

    500 mg magnesium citrate

    I track using fitday. I'm grain, legume, dairy, sugar and processed food free and follow a paleo type dietary plan.

    Is this okay?

    I meant:

    600 mg calcium citrate in total but dosage is split between two seperate meals.

    I've seen research that shows the body produces more MGP and other calcium handling proteins with higher doses of Vitamin D.  You would expect this effect as a evolutionary collaboration with Vitamin D activity.  Higher doses of Vitamin K2 are needed to carboxylate these proteins and make them active.  These proteins are active in various places in the body like the arteries and the kidneys.  I have a theory that taking Vitamin K2 helps prevent kidney stones and maybe gallbladder stones of the calcium type.

    Uncarboxylated MGP is actually worse than the fully carboxylated MGP.  Guinea pigs are given cholesterol and high levels of Vitamin D in research to give them artery disease by exceeding their Vitamin K2 levels thus creating low carboxylation levels.

    More Vitamin K2 may well be good for those kidney stones.

    There is recent and startling Dutch research to the point that Vitamin K2 is specifically used to carboxylate calcium handling proteins that remove calcium from the arteries and promote heart health.  If you are taking extra Vitamin D, the body also generates more of these calcium handling proteins so the need for Vitamin K2 also increases.

    I had good experience over six months with taking Vitamin K2 and found my running speed increased by 8% and the itching or other mild, variable sensations in my chest have decreased 98%.  I suspect this is connected to reduction of calcification.  I noticed a reduction in my symptoms after six weeks.

    My Vitamin K2 has:
      1300 mcg Vitamin K2, Mk-4
       100 mcg Vitamin K2, MK-7
      1000 mcg Vitamin K (the ordinary stuff)

    Reading all these posts I used to think of vitamin D and magnesium and K2 the same a most posters. Intuitively never took calcium, was up to 6000 mg of D3/ day to achieve a level of 43- up from 26.

    That said, my serum calcium has trended upward to 10.3. I am now having a few blood tests to check  for hyperparathyroidism!  The foremost parathyroid doc in the USA is Dr. James Norman from Tampa, and his website is very informative and puts a different spin on what I thought I knew of these matters. Parathyroids is ALL he and his 2 colleagues do all day every day. Please give this a look to be fully informed on the matter of Vitamin D supplementation.       www.parathyroid.com
    I have no connection, but if I find out I have an adenoma on one of my parathyroids, this is where I will have it removed!

    Oops,  meant to add I have also supplemented with 400-800mg of magnesium and 1 Life Extension K2 in addition to the Vitamin D for several years.
