Dr. Jarvik, is niacin as bad as it sounds?

A popular health newsletter, Everyday Health, carried this headline:

A Cholesterol-Busting Vitamin?

Did you know that niacin, one of the B vitamins, is also a potent cholesterol fighter?
Find out how niacin can help reduce choleseterol.


At doses way above the Recommended Dietary Allowance — say 1,000–2,500 mg a day (1–2.5 grams) — crystalline nicotinic acid acts as a drug instead of a vitamin. It can reduce total cholesterol levels by up to 25%, lowering LDL and raising HDL levels, and can rapidly lower the blood level of triglycerides. It does so by reducing the liver’s production of VLDL, which is ordinarily converted into LDL.


I'd agree with that, except that it is rare to require doses higher than 1000-1500 mg per day unless you are treating lipoprotein(a) and using niacin as a tool for dramatic drops in LDL. But for just raising HDL, shifting HDL into the healthy large class, reducing small LDL, and for reduction of heart attack risk, 1000-1500 mg is usually sufficient; taking more yields little or no further effect.

But after that positive comment comes this:

Niacin is safe — except in people with chronic liver disease or certain other conditions, including diabetes and peptic ulcer. . . However, it has numerous side effects. It can cause rashes and aggravate gout, diabetes, or peptic ulcers. Early in therapy, it can cause facial flushing for several minutes soon after a dose, although this response often stops after about two weeks of therapy and can be reduced by taking aspirin or ibuprofen half an hour before taking the niacin. A sustained-release preparation of niacin (Niaspan) appears to have fewer side effects, but may cause more liver function abnormalities, especially when combined with a statin.


Strange. After a headline clearly designed to pull readers in, clearly stating niacin's benefits, the article then proceeds to scare the pants off you with side-effects.

But look to the side and above the text: Ah . . . two prominent advertisements for Lipitor, complete with Dr. Robert Jarvik's photo. "I've studied the human heart for a lifetime. I trust Lipitor to keep my heart healthy."

Niacin bad. Lipitor good. Even celebrity doc says so. Sounds like bait and switch to me. "You could try niacin--if you dare. But you could also try Lipitor."

Who is Dr. Jarvik, anyway, that he serves as spokesman (or at least figurehead) for this $13 billion dollar a year drug? Of course, he is the 1982 inventor of the Jarvik artificial heart, surely an admirable accomplishment. But does that qualify him to speak about heart disease prevention and cholesterol drugs?

Jarvik has never--never--actually prescribed Lipitor, since he never completed any formal medical training beyond obtaining his Medical Doctor degree, nor has he ever had a license to practice medicine. He does, however, continue in his effort to provide artificial heart devices, principally for implantation as a "bridge" to transplantation, i.e., to sustain a patient temporarily who is dying of end-stage heart failure.

So where does his expertise in heart disease prevention come from? It's beyond me. Perhaps it was the thousands of dollars likely paid to him. That will make an "expert" out of just about anybody.

Robert Bazell, science reporter, for CNBC, made this report on the Jarvik-Lipitor connection in his March, 2007 report, Is this celebrity doctor's TV ad right for you?

Mr. Bazell writes:

On May 16, 1988, an editorial in the New York Times dubbed the artificial heart experiments, “The Dracula of Medical Technology.”

“The crude machines,” it continued, “with their noisy pumps, simply wore out the human body and spirit.”

Since then, in a series of start-up companies, Jarvik has continued his quest to make an artificial heart — as have several other firms. One competitor recently won FDA approval to sell its device for implantation in extreme emergencies.

Perhaps Jarvik’s chances of success with another artificial heart account for his willingness to serve as pitchman for Pfizer. I inquired, without success, to find the going rate for a semi- celebrity like Jarvik to appear in such ads. Thomaselli of Advertising Age said whatever it is, it is “infinitesimal” compared to Pfizer’s expenditures of $11 billion a year on advertising, much of it for Lipitor.

Why spend so much marketing Lipitor?

Because Lipitor is only one of six drugs in the class called statins that lower cholesterol. Many cardiologists say that for the vast majority of people any one of these drugs works just as well as the other. Two of them, Mevacor and Zocor, have already lost their patent protection so they cost pennies a day compared to $3 or more a day for Lipitor.

In 2010, when Lipitor loses its patent protection, it, too, will cost pennies a day, and Pfizer will no longer need Dr. Robert Jarvik.



So, is niacin so bad after all? Or is this Everyday Health report just another clever piece of advertising for Pfizer?

    When you're diabetic, so many drug choices wind up being about that.  For instance, I was switched to carvedilol (at my request) as it's the only beta-blocker that doesn't raise bg and actually seems to improve insulin resistance.

    I think it is true that niacin at doses therapeutic enough to effect lipid panels is a drug, not a vitamin.  This isn't to say it's bad, but that it has to be evaluated as a drug.  And the best I've been able to find wrt to niacin use in diabetics is that 1-1.5 g of extended release only raises bg slightly.  

    However, the increased A1c, even if slight, bothers me.  Even in non-diabetics, A1c is highly correlated with heart disease; very slight changes seem to be significant.  So it is difficult to decide if the increased glycolyation of blood proteins outweighs the benefits of niacin.  

    Have you seen improvements in heart scan scores in diabetics treated with niacin?

    Yes, dramatic reductions in heart scan scores, in fact.

    I think that the glucose/niacin interaction needs to be evaluated individually, since it can vary enormously from one person to another, though usually small to minimal.

    1500 niacin has lowered my LP(a)from 90 to 28. Also alternate between 10mg and 5mg daily of Lipitor to keep LDL & Trigs about 35. Cardiologist says "less trains = less passengers". HDL at 60-70. Found Immediate release worked best for me. Reading good things about that combo on PUBMED.com. Doing it for 5 yrs now. Thanx for your helpful posts, a must read for me every day. Over&Out

Is it exercise or diet?

Is it exercise or diet?

Wayne, a 61-year old retired school superintendent, had been an exercise fanatic all his adult life. If not running long distances and occasional marathons, he'd bike up to 70 miles a day. He did this year-round. In cold weather, he set his bicycle up on an indoor device and also ran on a treadmill and added weight training.

That's why it was kind of surprising that he sported a large belly. At 5 ft 8 inch and 190 lbs, that put his Body Mass Index (BMI) also high at 28.8 (desirable <25). You'd think that vigorous, almost extreme, exercise like this would guarantee a slender build.

Wayne also had lipoproteins to match: triglycerides 205 mg/dl, LDL 176 mg/dl but LDL particle number much higher at 2403 nmol/l (an effective LDL of 240 mg/dl); 75% of LDL particles were small.

I asked Wayne about his diet. "I eat healthy. Cheerios for breakfast usually. Some days I'll skip breakfast. Lunch is almost always a sandwich: tuna, turkey, something like that on whole wheat bread or a whole wheat bagel. Chips, too, but I guess that's not too healthy. Dinners vary and we eat pretty healthy. Almost never pizza or junk like that."

"Pasta?" I asked.

"Oh. sure. Two or three tiems a week. Always whole wheat. With a salad."

Wayne was well aware of the conventional advice for whole grains and, indeed, had been trying to increase his intake, particularly since his basic cholesterol numbers had been high in past. To his surprise, the more he tried at diet, the more LDL seemed to go up, as did triglycerides.

I see this situation every day: The obsession with processed carbohydrate foods, worsened by the message perpetuated by the American Heart Association, the USDA Food Pyramid, Kraft, Kelloggs, Post, etc. Eat more fiber, eat whole grains.

NY Times columnist, Jane Brody, chronicles her (embarassing) mis-adventure following the same mis-guided advice in Cutting Cholesterol, an Uphill Battle.

According to the USDA Food Pyramid, Wayne is not getting enough grains and whole grains, particularly since he is highly physically active. Consistent with the message given by the food industry: "Eat more!"

The food industry-supported Whole Grain Council advises:

Whole Grains at Every Meal
The US Dietary Guidelines recommend meeting the daily requirement by eating three "ounce-equivalents" of breads, rolls, cereals or other grain foods made with 100% whole grains. A slice of bread or a serving of breakfast cereal usually weighs about an ounce.

Want an easier way to think about it? Just look at your plate at each meal, and make sure you've included some source of whole grains. That's why our slogan is "Whole Grains at Every Meal."



By this scheme, if you are overweight, it's because you lack fiber and you're too inactive. "Get up and go!" It's not the diet, they say, it's you!

See through this for what it is: Nonsense. Wayne was overweight, packing 20 extra pounds in his abdomen from his over-dependence on processsed carbohydrates--"whole grains"--not from inactivity.

    I'm also an 'exercise fanatic'.  I've run well over 50 marathons.  I lived the high-carb lifestyle because  the literature was saying carbs are necessary for athletics. And in consequence my cholesteral was always above 290.  Now I'm following a lower carb diet and have seen the cholesterol level drop to 210.  And since reading Colpo and Traubes' new book I'm less worried about cholesterol.

    When we eliminate grains and the filling feeling that comes from eating grains,it's difficult to know what the replacement should be.
    Protein? Fat? Low glycemic vegs?
    Some combination of the three?
    If the answer is a combination,  the amount to feel full eating the low glycemic vegs is often large and we wonder whether the insulin response is similar to the grains we eliminated.

    Good questions. That's why we often base details of diet on lipoprotein patterns. Someone with severe small LDL, for instance, may do best to reduce grains as much as possible, increase healthy oils and proteins accordingly.

    We are still working on the new Track Your Plaque diet that will incorporate some of the more recent experiences in diet manipulations.

    Hey Jason,

    I discovered this blog and Dr. Davis' TYP program at the beginning of September.  I have relatively successfully cut carbs and grains from my diet thus far.

    Because I've got some weight to lose, I have tried to keep the carb count low and I've lost 15 pounds since then.

    I have also been very surprised at the significant reduction in my appetite.  I've read about the experience of others with regard to appetite reduction and couldn't really imagine that it could happen for me too.  But it has.

    A few weeks ago, I attended a party catered by one of my favorite italian restaurants and got myself offtrack for two days.  Then it took me a couple of days to get back on track because my appetite returned.

    Check out Jimmy Moore's website for lots of ideas about variations of foods to try.  The latest thing I picked up from Jimmy is the good old-fashioned hard boiled egg.  Two or three eggs with some spicy hot sauce for breakfast and a handful of almonds mid-morning plus a couple glasses of water and I'm good for the morning no problem.

    I find myself thinking about lunch not because I'm really hungry but out of habit.

    The cool thing too now is that the more I do this, the more I'm just not tempted much to do anything but this diet.

    I am also repeatedly impressed with the dramatic loss of appetite that carbohydrate restriction brings. It is a real effect though one, I regret, that is probably difficult or impossible to precisely and scientificaly quantify.

    I thought Taubes explained it well:  Control insulin and you automatically control appetite.

    I am 56 years old. I have survived a major stroke in May 2004, most recently I experienced V-Tach and triple bypass and a stint in 2006. I quit smoking in 1992.

    Since mid-August I have ridden my bike close to 500 miles. I often ride 100 miles at a time. I have extremely low chorestoral, (below 100). I have lost close to 30 pounds since surgery and weigh in at 204, medium frame, 6-2.(Sounds like a boxer..in this corner!)

    I often see healthy bikers that ride with me that are overweight. I try to balance all my meals, I don't live with the Cardiac Diet, but I respect it. I eat fresh meals, hardly ever prepared, and I eat in smaller dozes and at many times of the day...I think that I am on the right track! I am new to this blog and I really appreciate it!
