High-density Lipoproteins (HDL)

Note:  I see a lot of orders for no-flush niacin.  I assume the reason people are buying this is to raise HDL cholesterol.  I couldn't find any research that no-flush niacin works to increase HDL.  It's probably a waste of money for the no-flush.  Just do a Medline search of  hexanicotinate HDL, hexaniacinate HDL or no-flush niacin.  Here are the the only studies I could find:

Accumulation of chylomicron remnants and impaired vascular reactivity occur in subjects with isolated low HDL cholesterol: effects of niacin treatment - Atherosclerosis. 2006 Jul;187(1):116-22 - "evaluation of no-flush niacin treatment ... Twenty-two low HDL subjects with reduced FMD were randomized into two groups, one given 1.5 g/day niacin and a placebo group. After 3-month treatment, plasma lipids and chylomicron kinetics were not changed by niacin treatment"

Varying cost and free nicotinic acid content in over-the-counter niacin preparations for dyslipidemia - Ann Intern Med. 2003 Dec 16;139(12):996-1002 - "Commonly used over-the-counter niacin preparations (500-mg tablets or capsules) from the 3 categories of immediate-release, sustained-release, and no-flush were purchased at health food stores and pharmacies and from Internet-based vitamin companies ... The average content of free nicotinic acid was 520.4 mg for immediate-release niacin, 502.6 mg for sustained-release niacin, and 0 for no-flush niacin ... No-flush preparations of over-the-counter niacin contain no free nicotinic acid and should not be used to treat dyslipidemia. Over-the-counter sustained-release niacin contains free nicotinic acid, but some brands are hepatotoxic. Immediate-release niacin contains free nicotinic acid and is the least expensive form of over-the-counter niacin"

I’ve been taking three grams per day of the immediate release niacin (Twinlab).  It raised my HDL from 39 to 57.  Then I switched from Actos to Avandia (both to prevent diabetes) and my HDL went back down to 47. I’m switching back to Actos when I run out of Avandia. I don’t experience any flushing from the IR anymore. I think it took a couple months to get used to it plus I built up to three grams gradually. The IR didn’t have any noticeable effect on my liver enzymes. My ALT is 35. My doctor thinks that’s great. Normal goes up to 60 but I read that you want it below 30 but the 35 was about what it was before the niacin. My father died of liver cancer so I keep an eye on my liver enzymes but my father drank like a fish plus he was 87 when he died.  See:

Elevated ALT Levels Predict Risk of Death From Liver Cancer - Medscape, 11/2/06 - "Upper limits of normal range from 30 IU/L to 60 IU/L, depending on the laboratory. "We want to reset it southward of 30 IU/L," ... ALT levels are a reflection of the general vascular condition ... If the level is above 30, then that person probably has a problem — fatty liver or some vascular disease, including occlusive coronary artery disease"

http://www.lipidsonline.org/slides/slide01.cfm?tk=25&dpg=34 shows that with extended release niacin, HDL peaks out at 2,500 mg.  http://www.lipidsonline.org/slides/slide01.cfm?q=effect+of+niacin&dpg=4 shows immediate release crystalline niacin compared to Niaspan.  There isn't much gain in HDL with the immediate release crystalline niacin after 1,000 mg per day.  After seeing that, I'll probably cut down from 3,000 mg but from the slide it appears that there is a significant advantage to lowering triglycerides by going to 3,000 mg plus there is a linear decrease in LDL-C by going to 3,000 mg immediate release crystalline niacin.  This graph also shows that immediate release crystalline niacin is significantly better at raising HDL and lowering triglycerides compared to Niaspan.  Also see the slide titled CHD Risk According to HDL-C Levels.

I’ve never seen any studies on Niaspan and liver damage but it would seem like it would be similar to the slow release niacin. The only study I’ve seen on that is:

A comparison of the efficacy and toxic effects of sustained- vs immediate-release niacin in hypercholesterolemic patients - JAMA. 1994 Mar 2;271(9):672-7 - "None of the patients taking IR niacin developed hepatotoxic effects, while 12 (52%) of the 23 patients taking SR niacin did"

Be sure to see a doctor to have your liver enzymes checked before and after taking any niacin supplement.  See the bottom of http://www.lipidsonline.org/slides/ for some great slide shows on HDL.  The January 2007 Harvard Men's Health Newsletter has a good article on HDL cholesterol but it is a paid subscription.  See niacin at Amazon.com and niacin at Amazon.com.

  • Effects of Diet on High-Density Lipoprotein Cholesterol - Curr Atheroscler Rep. 2011 Sep 8 - "Multiple dietary factors have been shown to increase high-density lipoprotein cholesterol (HDL-C) concentrations, and HDL-C has been inversely associated with coronary heart disease (CHD) risk. Replacement of dietary carbohydrate with polyunsaturated, monounsaturated and saturated fat has been associated with progressively greater increases in HDL-C (7-12%) in addition to other lipid changes. Added sugars, but not high glycemic carbohydrates, have been associated with decreased HDL-C. Alcohol consumption has been associated with increased HDL-C (9.2%) independent of changes in other measured lipids. Modest effects on HDL-C (~4-5%) among other lipid and non-lipid CHD risk factors have also been observed with weight loss by dieting, omega-3 fatty acids, and a Mediterranean diet pattern. The CHD benefit of increasing HDL-C is unclear given the inconsistent evidence from HDL-raising pharmacologic trials. Furthermore, pleiotropic effects of diet preclude attribution of CHD benefit specifically to HDL-C"

  • Biology Of Flushing Could Renew Niacin As Cholesterol Drug - Science Daily, 4/6/09 - "Niacin, also known as nicotinic acid or vitamin B3, has long been regarded as one of the most effective weapons in managing cholesterol. It can lower levels of triglycerides, fatty acids and to a lesser extent, the "bad" kind of cholesterol (LDL) while at the same time powerfully increasing the "good" kind (HDL). But there's a catch – a big one. Patients don't like to take niacin because in most of them, it causes embarrassing, uncontrollable intense flushing, a rush of blood to the face and other skin surfaces accompanied by a prickling sensation ... One particular protein in that group, beta-arrestin1, was found to trigger the chemical reaction that led to flushing ... beta-arrestin1 plays no role whatsoever in niacin's ability to lower cholesterol and fatty acids ... the discovery opens the door to the possibility of developing a "biased ligand," a drug that would trigger GP109A, but not the beta-arrestins"

  • Gender-specific associations between lipids and cognitive decline in the elderly - Eur Neuropsychopharmacol. 2014 Feb 17 - "In men, a hypercholesterolemic pattern in late-life (high total cholesterol (T-C), low HDL-C, high LDL-C levels) was associated with a 25 to 50% increased risk of decline over 7 years in psychomotor speed, executive abilities, and verbal fluency ... In contrast, in women, a 30% higher rate of decline was found in psychomotor speed with high HDL-C levels and in executive abilities with low levels of LDL-C and triglycerides, in interaction with hormonal treatment. For men and women, vascular pathologies only slightly outweighed the risk related to lipids. This suggests a complex gender-specific pattern of cognitive decline involving genetic vulnerability in men and hormonal status in women" - Note:  Did I read that right?  HDL-C is good for cognition in men but bad for cognition in women?
  • Cholesterol levels linked to early signs of Alzheimer's in brain - nbcnews.com, 12/30/13 - "Reed and his team studied brain scans of 74 patients in stroke clinics and senior centers using Pittsburgh Compound B, or PIB, a tracer dye that highlights amyloid in the brain. The patients were, for the most part, normal and free of any symptoms of dementia ... But when the scientists measured the cholesterol in their blood, and teased out the two types, they found that patients with high levels of low-density lipoprotein or LDL cholesterol and low levels of high-density lipoprotein or HDL cholesterol showed higher PIB levels ... That means that the good and bad effects of the two kinds of cholesterol may occur long before people develop Alzheimer’s symptoms, perhaps offering a new chance for early intervention ... The American Heart Association has long said that keeping levels of HDL “good” cholesterol up — above 60 milligrams per deciliter of blood — and levels of LDL “bad” cholesterol — below 100 mg/dL — can prevent heart disease.

  • Evolving Concepts of the Role of High-Density Lipoprotein in Protection from Atherosclerosis - Curr Atheroscler Rep. 2011 Mar - "HDL is able to interact with and remove cholesterol from the lipid-laden foam cells in the peripheral vasculature with subsequent transportation to the liver for excretion. However, HDL has multiple other physiologic effects that may play a significant role in protection from atherosclerosis. HDL has been demonstrated to exhibit multiple beneficial effects on the coagulation system. Platelet function is improved by both direct and indirect mechanisms. HDL has a complex interaction with the protein C and protein S system. Thrombolytic balance is also improved by HDL. HDL has been demonstrated to have a significant natural antioxidant effect that inhibits the oxidative step required for low-density lipoprotein uptake by the macrophage. Additionally, HDL has also been demonstrated to exert multiple beneficial effects on endothelial function, including decreased apoptosis and endothelial repair" - See niacin at Amazon.com (niacin increases HDL).

The researchers noted that despite newer recommendations incorporating HDL into risk assessment, LDL continues to be the major target of cholesterol-lowering therapy ... Certain low-fat diets that reduce both LDL and HDL levels may be less beneficial than diets that boost HDL cholesterol levels. Losing weight, quitting smoking, and exercising more often can increase HDL cholesterol"

In addition, high levels of HDL are able to protect LDL from oxidation, and this ability is strongly enhanced when estrogens are present ... Although recent randomised control trials have shown that HRT in older women may not reduce the incidence of coronary heart disease, Dr. Bhavnani believes that this is not the whole story"
  • A Healthy Heart - Newsweek, 6/16/03 - "If small LDL is the kind of cholesterol you definitely don’t want to have, then HDL2B is the kind you definitely do want to have, and the more the better. HDL2B is a superefficient type of HDL, the good cholesterol that helps clear partially blocked arteries. HDL2B, the strongest possible protection against heart disease, is measured as a percentage of total HDL, and Superko likes his patients to be above 35 percent (for postmenopausal women, above 45 percent)" - See below.  Many are recommending HDL be a lot higher than that. - Ben

  • Raising HDL-C Levels Slows CAD Progression and Reduces Mortality - Medscape, 4/3/04 - "Results of two studies of high-density lipoprotein cholesterol (HDL-C)-targeted therapies indicate that attacking heart disease by increasing HDL-C levels appears to slow progression of atherosclerosis and reduce mortality ... Although the protective effect of HDL-C is well known, "most researchers ignore this fact," said Henrietta Reicher-Reiss, MD, from Sheba Medical Center in Tel Hashomer, Israel. It is a costly oversight since "about half of heart attack victims have normal [low-density liprotein cholesterol (LDL-C) levels]," ... drugs designed to target HDL-C have a number of adverse effects. Niacin, for example, causes flushing, and fibrates are associated with gastrointestinal side effects. That side-effect profile might be a factor against this approach. Statins, on the other hand, tend to be very well tolerated"
  • Exercise Training, Without Weight Loss, Increases Insulin Sensitivity and Postheparin Plasma Lipase Activity in Previously Sedentary Adults - Medscape, 3/19/03 - "Exercise, without weight loss, increases SI [insulin sensitivity] and PHPL activity in previously sedentary adults, without changing K2 or fasting lipid levels. Furthermore, increased LPL is associated with a decreased total:HDL ratio, and an increased LPL:HL ratio is associated with a decreased waist circumference. Therefore, even modest amounts of exercise in the absence of weight loss positively affect markers of glucose and fat metabolism in previously sedentary, middle-aged adults" - I threw this out because I didn't know that "decreased total:HDL ratio ... is associated with a decreased waist circumference" - This might be a long shot but that sounds like increasing insulin sensitivity via such methods as metformin and increasing HDL via supplements such as niacin might decrease pot bellies. - Ben
  • HDL Cholesterol Level Linked To Longevity, Cognitive Function - Clinical Psychiatry News, 2/03 - "A group of centenarians maintained significantly higher than normal HDL cholesterol levels, and within the group the parameter was strongly correlated with cognitive function ... The centenarians' offspring were also significantly healthier than their spouses: They were half as likely to have diabetes or heart attacks and had significantly lower blood pressure. No strokes occurred among the offspring ... The presence of HDL might explain the health and longevity in these families. The serum concentration of HDL typically declines with age by a mean of 5 mg/dL every 8 years ... Had the decline followed the normal pattern, the centenarians' HDL would have been about 20 mg/dL. But the actual mean value in the group was 55 mg/dL"

Yet trans fats are just as bad. They may even be worse ... Trans fat increases 'bad' LDL cholesterol -- in some studies more than saturated fat ... It also has a tendency to reduce 'good' HDL cholesterol, which saturated fat doesn't do ... Trans fat also increases blood levels of two other bad actors. One is the kind of fat called triglycerides. The other is a particle called lipoprotein(a), which promotes clogged arteries ... Any amount of trans fat is bad"

  • Atkins diet good for cholesterol - USA Today, 11/18/02 - "After six months, the people on the Atkins diet had lost an average of 31 pounds, compared with 20 pounds on the AHA diet, and more people stuck with the Atkins regimen ... Total cholesterol fell slightly in both groups. However, those on the Atkins diet had an 11% increase in HDL, the good cholesterol, and a 49% drop in triglycerides. On the AHA diet, HDL was unchanged, and triglycerides dropped 22%. High triglycerides may raise the risk of heart disease" - That may be true but what about a diet devoid of anti-oxidants making you old before your time.  Plus, how much of that extra 11 pounds was water loss? - Ben
