Recent Longevity News for the seven days ending 7/30/08.  You should consult your doctor if you are taking any medications.

Vitamin C-rich diet may slash diabetes risk - Nutra USA, 7/29/08 - "Increased blood levels of vitamin C may reduce the risk of developing diabetes by 62 per cent ... Correlating blood levels of vitamin C and diabetes, the researchers found that men and women with the highest blood levels (at least 1.10 and 1.29 mg/dL, respectively) had a 62 per cent reduction in their risk of developing type-2 diabetes, compared to men and women with the lowest blood levels (less than 0.56 and 0.77 mg/dL, respectively)" - See vitamin C products at Amazon.com.

Statins May Prevent Dementia in Older Adults - Doctor's Guide, 7/29/08 - "People at high risk for dementia who took statins were half as likely to develop dementia as those who do not take statins"

Prostate Cancer Therapy: Mental Impact? - WebMD, 7/29/08 - "ADT stands for "androgen-deprivation therapy" and is the standard type of treatment for prostate cancer that has spread to the bones or other organs ... there is a "strong argument" to be made that the hormone therapy is linked to "subtle but significant" cognitive declines in men with advanced prostate cancer"

Angiotensin Receptor Blockers Are Lower Incidence, Progression Of Alzheimer's Disease - Science Daily, 7/27/08 - "Researchers at Boston University School of Medicine (BUSM) have, for the first time, found that angiotensin receptor blockers (ARBs)—a particular class of anti-hypertensive medicines—are associated with a striking decrease in the occurrence and progression of dementia" - Note:  Telmisartan, which I've been saying should be a first line treatment, is an ARB.  See telmisartan at OffshoreRx1.com.

Low Vitamin D Levels Independent Predictor of Fatal Stroke - Medscape, 7/24/08 - "Low levels of vitamin D appear to be an independent predictor of fatal stroke — a finding that suggests supplementation may be a promising approach for stroke prevention" - See vitamin D at Amazon.com.

Bilberry and pine bark combo wards off glaucoma: study - Nutra USA, 7/24/08 - "intra-ocular hypertension (IOP) ... The bilberry and pine bark product was Mirtogenol, a combination of Indena's Mirtoselect standardised bilberry extract and Horphag's Pycnogenol pine bark extract ... IOP was also seen to be lowered in 19 of the 20 intervention patients, from an average of 25.2mmHg to 22.0mmHG. Only one of the control patients saw a drop in IOP" - [Abstract] - See bilberry at Amazon.com and Pycnogenol at Amazon.com.

Limiting Fructose May Boost Weight Loss, Researcher Reports - Science Daily, 7/24/08 - "One of the reasons people on low-carbohydrate diets may lose weight is that they reduce their intake of fructose, a type of sugar that can be made into body fat quick ... Fructose, on the other hand, enters this metabolic pathway downstream, bypassing the traffic cop and flooding the metabolic pathway"

Exercise Could Be The Heart's Fountain Of Youth - Science Daily, 7/23/08 - "Absence may make the heart grow fonder, but endurance exercise seems to make it younger ... older people who did endurance exercise training for about a year ended up with metabolically much younger hearts ... after endurance exercise training -- which involved walking, running or cycling exercises three to five days a week for about an hour per session -- the participants' hearts doubled their glucose uptake during high-energy demand"

Fish Oil, Red Yeast Rice Cut Cholesterol - WebMD, 7/23/08 - "We followed them for a three-month period ... The LDL declined 42% in the supplement group and 39% in the Zocor group ... The supplement group also lost an average of 10 pounds in 12 weeks, but there was no significant weight loss in the medication group. Triglyceride levels, while on average normal in both groups at the start, decreased by 29% in the supplement group but just 9.3% in the medication group -- a significant difference" - See red yeast rice at Amazon.com and Mega Twin EPA at Amazon.com.

Soy foods 'reduce sperm numbers' - BBC News, 7/23/08 - "A regular diet of even modest amounts of food containing soy may halve sperm concentrations" - [WebMD][Science Daily]

Expert Panel Makes Prediabetes Recommendations; Lifestyle Is No. 1 - WebMD, 7/23/08 - "In prediabetes, blood sugar levels are above normal but not high enough to be classified as diabetes -- yet. But prediabetes isn't harmless; it makes diabetes (and its many complications) more likely. And it's a risk for your heart right now ... The bottom line: Prediabetes is an immediate risk and a shadow hanging over your future health. So get aggressive about dealing with it now. Don't wait until it gets worse"

Pioglitazone Cuts Risk of Progression to Diabetes - Clinical Psychiatry News, 7/08 - "People with impaired glucose tolerance were 81% less likely to develop type 2 diabetes over a 3-year period if treated with pioglitazone ... Patients were randomized to treatment with placebo or 30 mg/day pioglitazone. If the drug was tolerated after 1 month, the dose could be increased up to 45 mg/day" - Note: Diabetes runs in my family.  I've been taking pioglitazone for several years for prevention plus I'm convinced that a higher blood sugar and a higher insulin (insulin resistance) is a major cause of aging.  See pioglitazone at OffshoreRx1.com.

Supplement Focus (Niacin):

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"

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.

General Niacin Information:

• Niacin - The Natural Pharmacist - "When used as therapy for a specific disease, niacin, niacinamide, and inositol hexaniacinate are taken in dosages much higher than nutritional needs, about 1 to 4 g daily. Because of the risk of liver inflammation at these doses, medical supervision is essential"
• Niacin (Vitamin B-3), Niacinamide - Intelihealth - "Thyroid function may also be impaired while taking niacin. Periodic monitoring of thyroid function is recommended ... Studies have used one to four grams of niacin daily for treating clogged arteries or heart disease"
• Extended-Release Niacin and Hyperlipidemia Management - November 15, 2000 - American Academy of Family Physicians - aafp.org - "Niacin can lower LDL cholesterol by 10 to 25 percent and triglyceride levels by 20 to 50 percent, and can raise levels of high density lipoprotein (HDL) cholesterol by 15 to 35 percent ... The daily niacin dosage was started at 375 mg taken nightly and slowly increased, to a maximum of 3,000 mg per day, at four-week intervals for a total of 25 weeks. Patients were permitted to take 325 mg of aspirin before taking the study medication if they wished to prevent flushing ... The dose response demonstrates a linear effect, with maximal benefit at a dosage of approximately 2,500 mg, although the maximum recommended dosage of extended-release niacin is 2,000 mg"
• Niacin - A New Look at an Old Drug - U.S. Pharmacist, 10/15/03 - "In one study, up to 53% of patients treated with IR niacin reported flushing, compared with 22% in the SR niacin group; four of the 23 IR-treated patients (17%) withdrew because of flushing. However, 67% of patients discontinued SR niacin therapy because of liver enzyme elevations (three times the upper limit of normal), and 52% of patients developed hepatotoxic symptoms; however, no patients treated with IR niacin developed significant changes in liver enzymes ... Because the incidence and severity of flushing often decreases with continued use—sometimes dissipating altogether—stress that any interruptions in therapy may lead to losing any tolerance" - Note:  I've been taking two grams of the TwinLab immediate release niacin for years and I don't get any flush from it if I take it with a little food. - Ben
• 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"

Niacin News & Research:

• Low Levels Of Good Cholesterol Linked To Memory Loss, Dementia Risk - Science Daily, 6/30/08 - "Researchers defined low HDL as less than 40 mg/dL ... At age 60, participants with low HDL had a 53 percent increased risk of memory loss compared to the high HDL group" - [WebMD] - The best way to increase HDL is niacin.  See niacin at Amazon.com.  Start slow maybe even with the 100 mg capsules.  It took me about three months to get immune to the flush from 2000 mg per day.  Taking it with soup seems to be the best.
• Niacin's Role In Maintaining Good Cholesterol - Science Daily, 6/5/08
• Combination Niacin-Laropiprant Plus Simvastatin Reduces Cholesterol by Almost 50% - Doctor's Guide, 11/6/07 - "When patients with dyslipidemia added simvastatin to their experimental combination of extended-release niacin and laropiprant -- a novel anti-flushing agent -- they reported reductions in low density lipoprotein cholesterol (LDL-C) of as much as 48% from baseline ... high density liopoprotein cholesterol (HDL-C) was increased by 28% and triglycerides decreased by 33%"
• 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%.
• Merck Niacin Drug Controls Cholesterol - Intelihealth, 9/5/07 - "The drug, called Cordaptive, can both raise good cholesterol and lower bad cholesterol. It combines an extended-release form of the B vitamin niacin with a chemical to inhibit an often intolerable niacin side effect called flushing -- redness, burning and tingling of the face ... compared with dummy pills, Cordaptive produced an 18 percent drop in levels of LDL-C, or "bad" cholesterol; a 26 percent drop in another type of blood fat called triglycerides, and a 20 percent increase in levels of HDL-C, or "good" cholesterol"
• Niacin (Nicotinic Acid) -- The Old Drug Is Making a Comeback With A New Act - Medscape, 6/11/07 - "Niacin (nicotinic acid) is well known as the most effective drug currently available for raising levels of high-density lipoprotein (HDL) cholesterol, raising it by 25% to 35% at the highest doses"
• FDA Approvals: Veramyst, Niaspan, and HepaGam B - Medscape, 5/9/07 - "Film-Coated Niacin Extended-Release Caplets (Niaspan) May Reduce Flushing ... use of the new orange-coated formulation significantly reduced the incidence of flushing by 9%"
• Combining Agents Leads to Safe Treatment of Lipid Abnormalities - Physician's Weekly, 5/7/07 - "Combining the use of statins and niacin should be encouraged because it appears to safely treat multiple lipid abnormalities in appropriate high-risk patients"
• 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"
• An Old Cholesterol Remedy Is New Again - New York Times, 1/23/07 - "In its therapeutic form, nicotinic acid, niacin can increase HDL as much as 35 percent when taken in high doses, usually about 2,000 milligrams per day. It also lowers LDL, though not as sharply as statins do, and it has been shown to reduce serum levels of artery-clogging triglycerides as much as 50 percent ... There’s a great unfilled need for something that raises HDL ... Right now, in the wake of the failure of torcetrapib, niacin is really it. Nothing else available is that effective" - See niacin at Amazon.com.
• Gene Tied To Longevity Also Preserves Ability To Think Clearly - Science Daily, 12/26/06 - "Centenarians were three times likelier to possess CETP VV compared with a control group representative of the general population and also had significantly larger HDL and LDL lipoproteins than people in the control group ... Researchers believe that larger cholesterol particles are less likely to lodge themselves in blood vessels" - Could niacin do the same thing?  See:
  • Effects of extended-release niacin on lipoprotein particle size, distribution, and inflammatory markers in patients with coronary artery disease - Am J Cardiol. 2006 Sep 15;98(6):743-5 - "Addition of niacin resulted in a 32% increase in large-particle HDL (p <0.001), an 8% decrease in small-particle HDL (p = 0.0032), an 82% increase in large-particle LDL (p = 0.09), and a 12% decrease in small-particle LDL (p = 0.008)"
• Prolonged-Release Nicotinic Acid Combined With a Statin in NAUTILUS - Medscape, 10/19/06 - "The safety and tolerability profiles of prolonged-release nicotinic acid did not differ in patients who were and were not taking a statin. In particular, there was no sign of serious hepatic or muscle toxicity in patients receiving prolonged-release nicotinic acid with a statin. The addition of prolonged-release nicotinic acid to a statin raised levels of HDL cholesterol"
• Comparative Effects on Lipid Levels of Niaspan and Statins - Medscape, 7/28/06 - "Niacin is the best HDL-cholesterol raising drug right now"
• Niacin Extended-Release Tablets Combined With Low/Moderate Dosed Statin Achieves Better Total Lipid Control Versus Higher Dose Statin Monotherapy or Simvastatin and Ezetimibe - Doctor's Guide, 6/22/06 - "patients given Niaspan in combination with a low to moderate dose of Lipitor or Crestor achieved equivalent reduction in LDL-C (51-58%), 1.2 to 1.9-fold greater decreases in triglycerides and 2.5 to 3.5 fold greater increases in HDL-C, than patients who received high-dose Crestor or Zocor/Zetia"
• Aspirin for Preventing Flushing from Niacin - Medscape, 6/13/06 - "the impact of flushing can be minimised by careful dose escalation, administering 'extended-release' NA at bedtime, administering ASA 30 min before 'extended-release' NA and avoiding alcohol or hot drinks near the timeof administration"
• Hypertriglyceridemia - Medscape, 6/1/06 - "ER niacin has been shown to lower the triglyceride level by ~25% and raise the HDL level by almost 30%"
• About 5% of Long-term Niacin Users Evolve Into HDL Hyperresponders - Doctor's Guide, 3/14/06 - "about 5% of patients on long-term therapy become hyperresponders, increasing their HDL levels by 50% or more ... Overall, these patients lost 4% of body weight while on niacin treatment"
• Combination Treatment Shown for First Time to Cause Regression of Atherosclerosis - Doctor's Guide, 11/16/05 - "reversal of atherosclerosis - a primary cause of stroke and heart attacks - can be achieved with a combination of Niaspan (prolonged-release nicotinic acid) and a statin ... ARBITER 2 clearly showed that statins alone are not enough to halt the progression of atherosclerosis even when the LDL-C target is met. However, the addition of Niaspan 1000 mg stopped the progression of atherosclerosis in 12 months ... a further 12 months of treatment with Niaspan and a statin actually achieves regression of atherosclerosis"
• Adding Niacin to Lovastatin Therapy Might Improve Efficacy for Dyslipidemia - Doctor's Guide, 10/5/05 - "Niacin has been shown to be one of the most effective drugs for improving levels of high-density lipoprotein (HDL) cholesterol, or good cholesterol ... Combining the best LDL lowering and best HDL raising drugs makes sense"
• Can Niacin Slow the Development of Atherosclerosis - Medscape, 5/20/05 - "Extended-release niacin slowed the development of atherosclerosis in adults with coronary artery disease, independently from statin therapy"
• The Effects of Niacin on Lipoprotein Subclass Distribution - Medscape, 1/19/05 - "the combination of niacin and a statin may be among the best available treatment options for many patients with complex forms of dyslipidemia ... Niacin effectively modifies all major lipids and lipoproteins with respect to both their quantity and quality. It is the most effective agent currently available for raising low levels of HDL cholesterol"
• Two-Pronged Cholesterol Approach Works - HealthDay, 11/11/04 - "Niacin is the most effective treatment to treat low HDL ... Overall, combining niacin with a statin slowed disease progression 68 percent more than a statin alone. The combination treatment also resulted in a 60 percent reduction in heart attacks, deaths, strokes, and other coronary events"
• Niacin in Diet May Prevent Alzheimer's - WebMD, 7/14/04 - "those who got the least niacin were 70% more likely to develop Alzheimer's disease than those who got higher amounts ... Those at the study's highest niacin level were getting 45 mg per day in diet and supplements"
• Niacin Extended-Release/ Lovastatin Combination Effective in Patients with Multiple Lipid Disorders - Doctor's Guide, 4/23/03 - "Treatment by niacin ER/lovastatin was found to be more effective than each of its components, showing improved levels of low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C) and triglycerides (TG)" - Note:  Niacin usually increases HDL (the good cholesterol) much more than statins.  From my own experience and from taking to others, it seems like many physician's may ignore low HDL.
• Statins May Cut Alzheimer's Risk - HealthDay, 4/21/03 - "extended-release niacin reduced brain cholesterol levels by 10 percent" - Note: Red yeast rice is a non-prescription statin but you should still check with your physician.  See iHerb or Vitacost red yeast rice products.
• 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"
• Vitamin K and niacin good for complexion, experts say - HealthDay, 3/26/03 - "Vitamin K was found to be successful in treating dark circles under the eyes. It's also been found effective for treating bruising on the face following dermatologic procedures such as laser treatment for spider veins ... Niacin shows promise as an over-the-counter ingredient in anti-aging products"
• Alzheimer's Disease and Dementia: Vitamins Can Help Prevent - WebMD, 2/28/03 - "High levels of a substance in the blood called homocysteine tops the list of potentially new risk factors for heart disease, stroke, and now dementia. A new study suggests that high homocysteine levels are linked with mental declines associated with Alzheimer's disease in elderly people ... High homocysteine levels can be treated very easily with vitamins, including folate, niacin, and B-12"
• Statin-Niacin Combination Counters Dyslipidaemic Cardiovascular Risk - Doctor's Guide, 12/20/02 - "Combined statin-niacin is a safe, tolerated therapy that lowers low density lipoprotein cholesterol and raises high density lipoprotein cholesterol ... At niacin doses of at least 1000 (mean 1480) mg/day added to a constant statin regimen in 29 patients, high density lipoprotein cholesterol rose significantly (by 20 percent)"

Their small, dense LDLc particle mass decreased from 27 +/- 11 mg/dL to 15 +/- 4 mg/dL. Total HDLc increased from 39 +/- 7 mg/dL to 51 +/- 11 mg/dL. Their HDL2, as the percentage of total HDLc mass, increased from 29 +/- 8 percent to 45 +/- 10 percent, and their Lp(a) decreased from 43 +/- 17 mg/dL to 25 +/- 10 mg/dL ... Twenty-one percent of the patients were unable to tolerate niacin because of reversible adverse effects. Another 14 percent were unable to adhere to the niacin dosing regimen of three times daily"
• 'Advent' Study Highlights Safety And Efficacy Of Niaspan (Niacin) In Diabetic Patients - Doctor's Guide, 7/22/02
• Niacin Helps Hearts - Nutrition Science News, 11/01
• question regarding your new cholesterol-lowering supplement, Policosanol - Life Extension Magazine, 11/01 - "Studies show that niacin (B3) in doses of 1.5 grams to 3 grams lower triglycerides levels and raise HDL concentrations. Those who tolerated higher doses of niacin (nicotinic acid) showed even more improvement in lipid levels. Some people taking just 1000 mg of flush-free niacin see an elevation in beneficial HDL. Green tea also has been shown to elevate levels of HDL while lowering serum triglyceride levels. In the Journal of Molecular Cell Biochemistry, curcumin has been demonstrated, in vivo, to decrease triglycerides and increase HDL. In a study published in 1989 by the Journal of Associated Physicians-India, 125 patients receiving gugulipid showed a drop of 16.8% in triglycerides, and a 60% increase in HDL cholesterol within three to four weeks. Make sure you are taking at least six Mega EPA fish oil capsules daily, as low dose fish oil may not adequately suppress triglycerides. Finally, there are some lifestyle changes you may wish to consider. If you are overweight, weight loss would be recommended, as it would help to lower triglycerides and raise HDL. Also, try reducing carbohydrates, which can raise triglycerides"

• Comparison of the Safety and Efficacy of a Combination Tablet of Niacin Extended Release and Simvastatin vs Simvastatin Monotherapy in Patients With Increased Non-HDL Cholesterol (from the SEACOAST I Study) - Am J Cardiol. 2008 May 15;101(10):1428-36 - "The efficacy and safety of 2 regimens of a combination of a proprietary niacin extended release plus simvastatin (NER/S; 1,000/20 and 2,000/20 mg/day) were compared with simvastatin monotherapy (20 mg/day) for 24 weeks ... The safety of NER/S was consistent with the safety profile of each individual component. In conclusion, this study showed that NER/S provided additional clinically relevant improvements in multiple lipid parameters and was safe and well tolerated"
• Effects of niacin on glucose control in patients with dyslipidemia - Mayo Clin Proc. 2008 Apr;83(4):470-8 - "the effects of niacin (</=2.5 g/d), alone or in combination with statins, on fasting glucose (an increase of 4%-5%) and hemoglobin A1c levels (an increase of </=0.3%) are modest, transient or reversible, and typically amenable to adjustments in oral hypoglycemic regimens without discontinuing niacin. Niacin therapy was infrequently associated with incident diabetes or the need for new insulin prescriptions. Studies showed important clinical benefits of niacin or niacin-statin regimens despite modest effects on glucose control. On a population basis, significant reductions in incidences of cardiovascular events and the degree of atherosclerotic progression associated with long-term niacin (or niacin-statin) therapy in patients with diabetic dyslipidemia outweigh the typically mild effects of this therapy on glycemic regulation"
• The flavonoid luteolin inhibits niacin-induced flush - Br J Pharmacol. 2008 Jan 28 - "Sustained release niacin effectively lowers serum cholesterol, LDL and triglycerides, while raising HDL. However, 75% of patients experience cutaneous warmth and itching known as flush, leading to discontinuation. Acetylsalicylic acid (aspirin) reduces this flush only by about 30% ... Quercetin and luteolin (4.3 mg per rat; 1000 mg per human), administered i.p. 45 min prior to niacin, inhibited the niacin effect by 96 and 88%, respectively. Aspirin (1.22 mg per rat; 325 mg per human) inhibited the niacin effect by only 30%. Niacin almost doubled plasma PGD(2) and 5-HT, but aspirin reduced only PGD(2) by 86%. In contrast, luteolin inhibited both plasma PGD(2) and 5-HT levels by 100 and 67%, respectively" - See quercetin at Amazon.com.
• Increased total and high-molecular weight adiponectin after extended-release niacin - Metabolism. 2008 Mar;57(3):404-9 - "at least part of the cardioprotective benefits of niacin may be attributed to a shift in the HMW/LMW adiponectin ratio in obese men with the metabolic syndrome"
• Preferential increase in high-molecular weight adiponectin after niacin - Atherosclerosis. 2007 Nov 7 - "treatment with niacin raises adiponectin between 52% and 95% in patients with the metabolic syndrome"
  • Adiponectin definition - medterms.com - "High blood levels of adiponectin are associated with a reduced risk of heart attack. Low levels of adiponectin are found in people who are obese (and who are at increased risk of a heart attack)."
• The effects of extended-release niacin on carotid intimal media thickness, endothelial function and inflammatory markers in patients with the metabolic syndrome - Int J Clin Pract. 2007 Nov;61(11):1942-8 - "After 52 weeks of treatment, there was a change of carotid IMT of +0.009 +/- 0.003 mm in the placebo group and -0.005 +/- 0.002 mm in the niacin group (p = 0.021 between groups). Endothelial function improved by 22% in the group treated with niacin (p < 0.001), whereas no significant changes were seen in the placebo group. High sensitivity C-reactive protein decreased by 20% in the group treated with niacin for 52 weeks (p = 0.013). Niacin increased HDL-C (p < 0.001) and decreased low-density lipoprotein cholesterol and triglycerides (p < 0.001) significantly, and there were no adverse effects on fasting glucose levels after 52 weeks of treatment" - See niacin at Amazon.com or niacin at Amazon.com.
• Safety considerations with niacin therapy - Am J Cardiol. 2007 Mar 19;99(6A):S22-31 - "Overall, the perception of niacin side effects is often greater than the reality. As a result, a valuable medication for cardiovascular risk is underused"
• Aspirin reduces cutaneous flushing after administration of an optimized extended-release niacin formulation - Int J Clin Pharmacol Ther. 2007 Feb;45(2):78-88 - "Aspirin significantly reduced the incidence, intensity and duration of flushing associated with reformulated niacin ER"
• Effects of extended-release niacin on lipoprotein particle size, distribution, and inflammatory markers in patients with coronary artery disease - Am J Cardiol. 2006 Sep 15;98(6):743-5 - "Addition of niacin resulted in a 32% increase in large-particle HDL (p <0.001), an 8% decrease in small-particle HDL (p = 0.0032), an 82% increase in large-particle LDL (p = 0.09), and a 12% decrease in small-particle LDL (p = 0.008)"
• Benefits of Niacin in Patients With Versus Without the Metabolic Syndrome and Healed Myocardial Infarction (from the Coronary Drug Project) - Am J Cardiol. 2006 Feb 15;97(4):477-9 - "Niacin decreased the occurrence of 6-year MI and 15-year total mortality similarly among patients with or without the MS. For example, in the total population, 15-year total mortality rates were 60% and 64% (hazard ratio 0.86) in patients with the MS treated with niacin and placebo, respectively, and 50% and 57% (hazard ratio 0.86) in those without the MS ... these results support the use of niacin in postinfarction patients with and without the MS"
• Effect of niacin on lipid and lipoprotein levels and glycemic control in patients with diabetes and peripheral arterial disease: the ADMIT study: A randomized trial. Arterial Disease Multiple Intervention Trial - JAMA. 2000 Sep 13;284(10):1263-70 - "After an active run-in period, participants were randomly assigned to receive niacin (crystalline nicotinic acid), 3000 mg/d or maximum tolerated dosage (n = 64 with diabetes; n = 173 without diabetes), or placebo ... Niacin use significantly increased HDL-C by 29% and 29% and decreased triglycerides by 23% and 28% and low-density lipoprotein cholesterol (LDL-C) by 8% and 9% ... Glucose levels were modestly increased by niacin (8.7 and 6.3 mg/dL [0.4 and 0.3 mmol/L]; P =.04 and P<.001) in participants with and without diabetes, respectively ... Our study suggests that lipid-modifying dosages of niacin can be safely used in patients with diabetes"
