Long time reader, first comment.
Thank you for so freely sharing all the information.

Thank you for this!  I have had this question for a long time given the number of things I take that "thin the blood."

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.

Hi, Kevin--

My two Boston terriers jump for their fish oil capsules, two every day!

I'm glad to hear from a veterinarian that the coat sheen is indeed from the fish oil.

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?

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.

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.

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.

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.

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....

Thanks for posting this. The question recently came up in our office. I like your assertion that omega-3s restore the blood to normal and remove abnormal clotting. And to comment on a post above, our dog has a beautifully shiny coat and takes 2 pure EPA capsules each day!

I have enjoyed reading That 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.

I've been drinking fish oil for many year and I don't have any chance in my body people use to said me that but I think it is just a rumor.

I'm also especially gratified that a woman now holds our record. I'm uncertain why, but the ladies have been shy and the men remain the dominant and vocal participants in our program. Speak up, ladies!

I haven't heard of this problem
fish oil supplements. But now we know what to tell them when this sort of concern comes up. Fish oil or Omega-3 is really beneficial to health. It's just important that it comes from clean waters.

What is an appropriate dose of fish oil for someone taking coumadin?

Dr. Davis, when  person is taking Tamoxifen...
(1) is it safe to take vitamin k2 or K1?
(2) will fish oil have a role in preventing blood clots?

Thanks for that.  I still take Lovaza; have been lazy about switching.  I just checked the price my mail-order pharmacy pays and it's $546 per bottle of 120, or just over $1.50 per capsule.  While considerably less than what you quoted, it's still $6 per day and $2185 per year!  I'd no idea.  Plus I take Niaspan for another $900 per year.  I'm switching to OTC for both.  No wonder insurance rates are going up!

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.

And we wonder why healthcare costs are spiraling out of control in america...

What's sad, is the problem isn't limited to just pharmaceuticals, so many other areas like diagnostic imaging and durable medical goods are so much more expensive than they should be.

Do your part to reduce healthcare costs: Reject the idea that fish oil, niacin, and vitamin D should be costly prescription agents.

Pay for them yourself for SUPERIOR preparations that you can obtain without a prescription. This small effort alone will save us all hundreds of millions of dollars.

Anyone know when Lovaza is going generic? I thought I read that perhaps by end of the year their exclusivity may be up, which should open up cheap prescription alternatives -- and sort of kill Lovaza's profits too.

I use otc niacin at about $3 a bottle, and one of the doctors I work with asked me why I hadn't asked my doc for a prescription for Niaspan.
I just didnt know where to begin.

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 !

Another way to save on prescription drugs--pill splitting. Too often the smaller dose costs almost as much as the bigger dose. Getting the bigger pill and cutting it down to smaller doses can save a lot of money.

I'm surprised we don't see scrips for "pharmaceutical-grade water", to wash these down.

pyker, its called "bottled water"

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?

"I'm surprised we don't see scrips for "pharmaceutical-grade water", to wash these down."

What, like this?

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.

Decisions, decisions, decisions!

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.
My jaw would've dropped if I hadn't been getting my vitamin D!

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.
