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.

January 2007 Harvard Men's Health Newsletter has a good article on
HDL cholesterol but it is a paid subscription. See

New Combination Drug Improves Multiple Cholesterol Disorders in Single Pill
- Doctor's Guide, 11/5/07 - "Simcor combines
prescription niacin and simvastatin, two FDA-approved medications with
established safety profiles, to target good cholesterol (HDL), bad
cholesterol (LDL), and triglycerides in a single pill" - Sounds
stupid to me. Why would you pay prescription drug prices for something
that is dirt cheap like niacin. It is the Niaspan form of niacin,
which they claim has less flush. I tried Niaspan and couldn't tell any
difference in the flush plus the flush eventually stopped even with
immediate release niacin. Plus I worry about increased liver damage
with Niaspan.
Click here for the study that concerns me which was sustained release
niacin, not Niaspan but it would seem to be similar. Plus immediate
release niacin is about 20% more effective at raising HDL than Niaspan.
Click here and note where Niaspan is on the graph. I'm just eye
balling the 20%.

New TNT Analysis Shows - Medscape, 10/3/07 -
"Among patients treated with statins, including those who achieved very low
levels of cholesterol with high-dose statin therapy, high-density
lipoprotein (HDL)-cholesterol levels are still predictive of major

Improving Outcomes With HDL Cholesterol - Physician's Weekly, 4/9/07 -
"Patients who have high HDL levels
appear to have better protection against vascular disease than others and
some variants of HDL may actually reduce plaque in the coronary arteries.
Essentially, HDL acts as a scavenger compound; it moves the lipids from the
blood vessel to the liver, where they are then excreted from the body ...
Currently, in the United States, the only medication other than statins
designed specifically to help physicians raise the HDL cholesterol levels in
their patients is niacin" - See

Cholesterol Ratio More Indicative Than LDL - Physician's Weekly, 7/21/03 -
"the ratio of LDL and HDL cholesterol may be better for
identifying the risk of heart disease compared to relying solely on the individual levels of each kind of cholesterol. The study found that the ratio of LDL to HDL cholesterol and the ratio of total cholesterol to HDL cholesterol can better predict the risk of heart disease rather
than measuring LDL levels alone. LDL/HDL ratios may more effective at identifying high-risk individuals and tracking their progress on cholesterol-lowering drugs. 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"

Estrogens as Antioxidants – Reducing Heart Disease in Younger Postmenopausal Women - Doctor's Guide, 7/4/03 -
"If
LDL becomes oxidised its ability to cause heart disease increases. If HDL becomes oxidised
its ability to protect against heart disease is lessened ... estrogens can act as antioxidants, which neutralise free radicals, and hence protect HDL from oxidation. 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
