Recent Longevity News for the seven days ending 12/26/12.  You should consult your doctor if you are taking any medications.

Under Laser Procedure, Face Renews Itself With Younger-Looking Skin  - CBS Chicago, 12/24/12 - "A newer Erbium laser helps patients heal more quickly, with less down time — about three to four weeks instead of three months ... The procedure costs anywhere from $1,200 to $4,000. The Erbium laser can also be used for burns and severe acne, laser hair removal and for full-face laser re-surfacing"

Cholesterol boosts the memory of the immune system - Science Daily, 12/21/12 - "They discovered that the composition of the lipids of a membrane is responsible for the clustering of the receptors. The lipid composition of a naive cell differs from that of a memory cell. Cholesterol is the key factor in this process, as it is present in higher concentrations in a memory cell. This higher concentration of cholesterol leads to the aggregation of receptors, because the cholesterol joins them together like glue"

Impaired Melatonin Secretion May Play a Role in Premenstrual Syndrome - Science Daily, 12/20/12 - "PMDD sufferers can experience depression, tension, and irritability of sufficient intensity to interfere with daily activities and relationships. Disturbed sleep is also a common symptom of the disorder, with up to 70% of patients frequently reporting either poor sleep quality with increased awakenings or excessive sleepiness during the symptomatic phase ... compared to healthy controls, PMDD women had significantly decreased melatonin secretion levels during the night-time hours ... Clinical implications of reduced melatonin in PMDD The prevalence of insomnia and depression are both about twice as high in women than in men" - See melatonin at Amazon.com.

Regular Marijuana Use by Teens Continues to Be a Concern - Science Daily, 12/19/12 - "Only 41.7 percent of eighth graders see occasional use of marijuana as harmful; 66.9 percent see regular use as harmful. Both rates are at the lowest since the survey began tracking risk perception for this age group in 1991. As teens get older, their perception of risk diminishes. Only 20.6 percent of 12th graders see occasional use as harmful (the lowest since 1983), and 44.1 percent see regular use as harmful, the lowest since 1979 ... A 38-year NIH-funded study, published this year in the Proceedings of the National Academy of Sciences, showed that people who used cannabis heavily in their teens and continued through adulthood showed a significant drop in IQ between the ages of 13 and 38 -- an average of eight points for those who met criteria for cannabis dependence. Those who used marijuana heavily before age 18 (when the brain is still developing) showed impaired mental abilities even after they quit taking the drug ... The risk of addiction goes from about 1 in 11 overall to about 1 in 6 for those who start using in their teens, and even higher among daily smokers"

Why being tired makes us look ugly - nbcnews.com, 12/19/12 - "Stress causes a drop in the skin’s ability to protect itself ... And stress can also lead to less melanin, causing that jaundiced, haggard look. Melanin pigments the skin, giving humans their complexion ... Not sleeping causes us to accumulate water under our eyes, giving us that extra "baggage" ... What you get from stress is the wrinkles of aging .. Stress causes you to age ... stress not only causes wrinkles on the face but wrinkles in your arteries, as well, which can cause serious problems at an earlier age ... Your cells are biologically 10 to 15 years older … if you are chronically stressed ... If you are 45, the cells signal as if they are 60 years old"

Babies' Vision Improves With Fatty Acid Formula Supplements - Medscape, 12/18/12 - "from the Department of Pediatrics at the Children's Hospital of Michigan in Detroit, and colleagues found that long-chain polyunsaturated fatty acid (LCPUFA) supplementation started within 1 month of birth significantly improved infants' visual acuity at 2, 4, and 12 months of age ... "[R]etinal cells have the highest concentration of [docosahexaenoic acid] in the human body ... the fatty acid is necessary not only for optimal retinal function but also for the proper function of the visual processing centers, optic tract, and optic nerve" - See Jarrow Max DHA at Amazon.com.

Critical Need for Iodine Supplements During Pregnancy and While Nursing - Science Daily, 12/18/12 - "Iodine levels in the US have been decreasing, which has the potential to negatively impact the mother and unborn child ... Iodine, which is not naturally made in the human body, must be consumed through foods rich in the element or through supplements. Iodine is required for the production of thyroid hormone, and adequate thyroid hormone levels are critical for normal fetal neurodevelopment. National and international health organizations currently recommend that pregnant women take at least 150 µg of potassium iodide daily ... There is concern that even mild iodine deficiency in pregnant women could lead to children with lower IQ's" - See iodine at Amazon.com.

Regular Aspirin Use 10 or More Years Ago Associated With Increased Risk of Type of Age-Related Macular Degeneration - Science Daily, 12/18/12 - "data from the Beaver Dam Eye Study, a longitudinal population-based study of age-related eye diseases conducted in Wisconsin ... The average duration of follow-up was 14.8 years ... regular use of aspirin use 10 years prior to the retinal examination was associated with late AMD (age- and sex-adjusted incidence, 1.8 percent for users vs. 1.0 percent for nonusers)"

Oxytocin, Social Sharing and Recovery from Trauma - Science Daily, 12/18/12 - "'social sharing of emotions' (SSE) ... SSE, like the neuropeptide oxytocin (OT) -- known variously as 'the hug hormone', 'the moral molecule' and 'the natural love drug' -- has a calming and bonding function in humans. So a team of researchers decided to examine whether it followed that administering oxytocin might ease this therapeutic and powerful 'social sharing of emotions' ... What they found was that OT did not make people more talkative -- the word counts in the letters were the same -- but it did increase the participants' willingness to share the specific component that is responsible for the therapeutic effects of social sharing: emotions. As the researchers note, "the findings are the more remarkable because they were obtained among men, who may be less inclined than women to express their emotions." ... there may be further implications for human health, related to OT's antagonistic effect on the stress hormone cortisol" - See Oxytocin Factor or Oxy Pro (Oxytocin) Nasal Spray at International Anti-aging Systems.

Vitamin D and risk of death from vascular and non-vascular causes in the Whitehall study and meta-analyses of 12 000 deaths - Eur Heart J. 2012 Dec 20 - "examined associations of plasma concentrations of 25(OH)D and cause-specific mortality in a prospective study of older men living in the UK and included findings in meta-analyses of similar studies identified by a systematic search reporting on vascular and all-cause mortality ... 13-year follow-up ... After adjustment for age and seasonality, higher concentrations of 25(OH)D were inversely and approximately linearly (log-log scale) associated with vascular and non-vascular mortality throughout the range 40-90 nmol/L. After additional adjustment for prior disease and cardiovascular risk factors, a doubling in 25(OH)D concentration was associated with 20% [95% confidence interval (CI): 9-30%] lower vascular and 23% (95% CI: 14-31%) lower non-vascular mortality. In meta-analyses of prospective studies, individuals in the top vs. bottom quarter of 25(OH)D concentrations had 21% (95% CI: 13-28%) lower vascular and 28% (95% CI: 24-32%) lower all-cause mortality" - See vitamin D at Amazon.com.

Effects of Korean ginseng berry extract on sexual function in men with erectile dysfunction: a multicenter, placebo-controlled, double-blind clinical study - Int J Impot Res. 2012 Dec 20 - "Ginseng is beneficial for many aspects of human physiology, including sexual function ... administered 4 tablets of either standardized Korean ginseng berry (SKGB, 350 mg ginseng berry extract per tablet), or placebo, daily, for 8 weeks. Efficacy was assessed with the International Index of Erectile Function (IIEF)-15 and premature ejaculation diagnostic tool (PEDT) at the end of the 4th and 8th week. We observed that the total and each of the individual domain scores of IIEF-15 increased from 40.95+/-7.05 to 46.19+/-12.69 significantly in the SKGB by the 8th week (P<0.05)" - See ginseng at Amazon.com.

Telmisartan modulates mitochondrial function in vascular smooth muscle cells - Hypertens Res. 2012 Dec 20 - "These findings demonstrate that telmisartan can have significant effects on mitochondrial metabolism in VSMC that are potentially relevant to the pathogenesis of cardiovascular disease and that involve more than just angiotensin receptor blockade and activation of PPARγ" - See telmisartan at OffshoreRx1.com.

Tolerability of different oral iron supplements: a systematic review - Curr Med Res Opin. 2012 Dec 20 - "Extended-release ferrous sulphate with mucoproteose appears to be the best tolerated of the different oral iron supplements evaluated"

Whole Milk Intake Is Associated with Prostate Cancer-Specific Mortality among U.S. Male Physicians - J Nutr. 2012 Dec 19 - "28-y follow-up ... Physicians' Health Study ... The intake of total dairy products was associated with increased PCa incidence [HR = 1.12 (95% CI: 0.93, 1.35); >2.5 servings/d vs. ≤0.5 servings/d]. Skim/low-fat milk intake was positively associated with risk of low-grade, early stage, and screen-detected cancers, whereas whole milk intake was associated only with fatal PCa [HR = 1.49 (95% CI: 0.97, 2.28); ≥237 mL/d (1 serving/d) vs. rarely consumed]. In the survival analysis, whole milk intake remained associated with risk of progression to fatal disease after diagnosis [HR = 2.17 (95% CI: 1.34, 3.51)]"

B vitamin intakes and incidence of colorectal cancer: results from the Women's Health Initiative Observational Study cohort - Am J Clin Nutr. 2012 Dec 19 - "Women's Health Initiative Observational Study ... Vitamin B-6 and riboflavin intakes from diet and supplements were associated with a decreased risk of CRC in postmenopausal women. Associations of B vitamin intake were particularly strong for regional disease and among women drinkers who consumed alcohol infrequently. Our study provides new evidence that the increased folate intake during the early postfortification period may have been associated with a transient increase in CRC risk"

LDL cholesterol-lowering effects of grape extract used as a dietary supplement on healthy volunteers - Int J Food Sci Nutr. 2012 Dec 19 - "A randomized, double-blind, placebo-controlled clinical trial was performed over 56 days and included 60 volunteers. Thirty volunteers took 700 mg of the grape extract, Eminol® (E), and 30 took the placebo (P). On comparison of the results, a decrease in total cholesterol (E: 213.77 +/- 4.1 mg/dl and P: 245.57 +/- 4.1 mg/dl; p = 0.01) and LDL cholesterol (E: 142.17 +/- 3.1 mg/dl and P: 165.13 +/- 3.1 mg/dl; p = 0.02) levels as well as an increase in antioxidant capacity (E: 65.63 +/- 5.8 μmol TE/mg and P: 57.80 +/- 7.7 μmol TE/mg; p < 0.01) and vitamin E (E: 11.46 +/- 0.5 μg/ml and P: 9.06 +/- 0.5 μg/ml; p = 0.018) was observed. This result indicates that the grape extract Eminol® modulated the lipid profile in terms of cardiovascular risk indicators, lowering total blood cholesterol and LDL cholesterol levels" - See Jarrow Formulas, OPCs + 95 at Amazon.com.

Neat Tech Stuff / "How To's":

• Oasis Mouth Moisturizing Spray, Mild Mint, 1 Fl oz (Pack of 3) - I was using this stuff for dry throat at night probably caused by snoring but it's expensive.  I found a solution using the empty sprayers.  Use maple syrup but it's too thick for the sprayer so you have to mix it with about 25% vodka.

General Information:

• 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"

News & Research:

• Raising HDL Levels May Not Lower Heart Attack Risk - WebMD, 5/16/12 - "Many clinicians still prescribe the vitamin niacin to help raise HDL levels, even though a government-funded trial proved disappointing ... The trial was halted early a year ago when it was determined that people with heart disease who had low HDL levels did not benefit from the treatment ... The drug company Pfizer abandoned its experimental HDL-boosting drug torcetrapib in 2006 when trials showed an increase in heart attack and stroke risk among users ... the new research casts even more doubt on the strategy of raising HDL to lower heart and stroke risk ... HDL levels are related to risk, but that doesn't mean that raising HDL is beneficial ... What we do know is that lowering LDL has a big impact on risk, so the take-home message remains, 'Get those LDL numbers down'"
• Niacin doesn't stop heart attacks, major study finds - Health - Heart health - msnbc.com - MSNBC, 5/26/11 - "The newest study tested Abbott Laboratories' Niaspan, an extended-release form of niacin that is a far higher dose than is found in dietary supplements ... the Niaspan users saw their HDL levels rise, and their levels of risky triglycerides drop, more than people who took a statin alone. But the combination treatment didn't reduce heart attacks, strokes or the need for artery-clearing procedures such as angioplasty ... That finding "is unexpected and a striking contrast to the results of previous trials," ... Also, there was a small increase in strokes in the high-dose niacin users — 28 among those 1,718 people given Niaspan compared with 12 among the 1,696 placebo users. The NIH said it was not clear if that small difference was merely a coincidence, as previous studies have shown no stroke risk from niacin. In fact, some of the strokes occurred after the Niaspan users quit taking that drug" - See my niacin and HDL pages for many more studies.  For one thing, there are waaaay more arguments for raising HDL than just heart disease.  Things such as centurions having unusually high HDL, prostate cancer, bowel cancer, impotence, Alzheimer's, etc., not to mention that it conflicts with other studies.
• 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).
• Preventing heart problems while keeping a cool head: Cause of flushing effect arising from cholesterol treatment with nicotinic acid - Science Daily, 7/26/10 - "The opposite approach, which involves increasing the concentration of "good" HDL cholesterol using nicotinic acid, has proven unpopular among patients up to now. The reason for this is that treatment with nicotinic acid has an unpleasant but harmless side-effect: the drug makes patients turn quite red in the face ... the higher an individual's level of HDL cholesterol, the lower his or her risk of contracting these diseases. For this reason, the strategy of increasing HDL plasma concentration through medication has become more prevalent of late. The drug on which most hopes are pinned here is nicotinic acid ... The flushing phenomenon can be prevented by inhibiting prostaglandin formation or blocking the prostaglandin receptors in the skin, while the desired effects of the nicotinic acid on lipid metabolism remain unaffected"
• Vitamin B3 shows early promise in treatment of stroke - Science Daily, 2/24/10 - "An early study suggests that vitamin B3 or niacin, a common water-soluble vitamin, may help improve neurological function after stroke ... Niacin is known to be the most effective medicine in current clinical use for increasing high-density lipoprotein cholesterol (HDL-C), which helps those fatty deposits ... Niacin essentially re-wires the brain which has very exciting potential for use in humans"
• Quality of HDL Differs in Diabetics But Improves With Niacin Therapy - Medscape, 12/22/09 - "HDL cholesterol in individuals with diabetes has impaired endothelial protective functions compared with the HDL from healthy subjects, although treatment with extended-release niacin can improve these endothelial protective effects"
• Adding Niacin Boosts Effectiveness of Simvastatin/ezetimibe - Medscape, 12/16/09 - "In high-risk patients with hyperlipidemia, the addition of extended-release niacin provides superior results to therapy with simvastatin and ezetimibe alone ... At 64 weeks, compared with simvastatin and ezetimibe alone, the triple combination significantly improved HDL cholesterol (+21.5%), triglycerides (-17.6%), non-HDL cholesterol (-7.3%), low-density lipoprotein cholesterol, apolipoprotein B and A-I, and lipoprotein ratios"

• Vitamin B niacin offers no extra benefit to statin therapy in seniors already diagnosed with coronary artery disease, study suggests - Science Daily, 11/18/09 - "This does not mean that niacin therapy may not have other cardiovascular benefits, but any such benefits are independent of reducing the amount of plaque buildup and patients should be aware of that ... Lima cautions that an ongoing national study of the long-term vascular benefits of dual therapy and whether extended-release niacin, also known as nicotinic acid, lowers death rates from heart disease should provide more definitive data" - Note:  The article implies that prescription Niaspan works better than immediate release niacin.  See http://www.lipidsonline.org/slides/slide01.cfm?q=effect+of+niacin&dpg=7 which implies the opposite.  The prescription might have less flush but I couldn't tell the difference.  Like I've said in the past, the flush gets less the longer you use it and is practically non-existent after you taken it for several months if you take it with food.  Also, the slow release may produce liver damages.  See:

  • 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 Tops Zetia in Cutting Artery Plaque - WebMD, 11/16/09 - "The question is whether ezetimibe works at all ... Niacin has been around for 50 years. It's a well-understood drug, and in this trial it was clearly superior ... Ultrasound images of neck arteries showed that Niaspan reduced artery plaque by about 2%. Zetia did not slow plaque buildup, although it did lower cholesterol"
• ARBITER 6-HALTS: HDL Raising With Niacin Superior to Ezetimibe - Medscape, 11/16/09 - "Adding extended-release niacin (Niaspan, Abbott) to statin therapy results in a significant regression of atherosclerosis as measured by carotid intima-media thickness (IMT), whereas the addition of ezetimibe (Zetia, Merck/Schering-Plough) to statin therapy did not, according to an eagerly anticipated study"
• Raising 'Good' Cholesterol Levels May Benefit Clogged Arteries - Science Daily, 11/6/09 - "Using MRI scans, we have shown a reduction in the size of artery walls in patients after a year of treatment with nicotinic acid ... Nicotinic acid, sometimes known as niacin, is one of the oldest drugs used for atherosclerosis and only fell out of favour as statins came to prominence. It is known to raise levels of good cholesterol in the blood"
• MRI study: Reduced carotid wall area with Niaspan - theheart.org, 10/30/09 - "So, in terms of relieving a stenosis, for example, it is not clinically relevant. The point is the direction of change. Atherosclerosis has, for years, been considered a relentlessly progressive disease process. To bring about a demonstrable reversal, however small, in only 12 months is mechanistically significant," he said. "Furthermore, remember that the plaque is heterogeneous. We don't know what compositional changes have been induced, but if, for example, the lipid component had been reduced—and there are data from other studies to suggest this happens—then even a small change in total size could be very relevant to plaque behavior."
• Ignored cholesterol blamed for heart attacks - MSNBC, 6/9/09 - "Statins — taken by millions to cut heart attack and stroke risk — do not affect lipoprotein (a) ... people with the highest liporotein (a) levels were two to three times more likely to have a heart attack than those with the lowest levels ... Niacin, a vitamin often prescribed generically to lower cholesterol, also lowers lipoprotein (a) levels. It can cause uncomfortable flushing, however. Aspirin can also lower lipoprotein (a) levels" - [WebMD]
• 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"
• 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"

• 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"

• 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 ...

• 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.

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.

• Niacin Administration Significantly Reduces Oxidative Stress in Patients with Hypercholesterolemia and Low Levels of High-Density Lipoprotein Cholesterol - Am J Med Sci. 2012 Sep 17 - "Oxidative stress has been implicated in the pathogenesis of cardiovascular disorders, including atherosclerosis. In pharmacological doses, niacin (vitamin B3) was proven to reduce total cholesterol, triglyceride, very-low-density lipoprotein, and low-density lipoprotein levels, and to increase high-density lipoprotein (HDL) levels ... Subjects with lower HDL-C levels exhibited higher oxidative stress compared with subjects with normal HDL-C levels. Niacin treatment in hypercholesterolemic patients caused a significant increase in HDL-C and apolipoprotein A1 levels, and a decrease in triglyceride levels. Niacin also significantly reduced oxidative stress ... These results indicate an additional beneficial effect of niacin beyond its ability to affect the lipid profile"
• Propionyl-L-carnitine, L-arginine and niacin in sexual medicine: a nutraceutical approach for erectile dysfunction - Andrologia. 2011 Oct 4 - "In a group of 54 unselected men (35-75 years), consecutively presenting to our ED clinic and naive to other ED treatments, we carried out a single-blind, one-arm study to evaluate the effects of a 3-month supplementation with propionyl-L-carnitine, L-arginine and niacin on their sexual performance ... Analyses on GAQs revealed that treatment improved erections in 40% of cases, with a partial response occurring in up to 77% of enrolled subjects. These preliminary findings indicate that the favourable cardiovascular effects of nutraceuticals might also reflect on male sexual function with possible implication in the treatment and prevention of ED. This study documents a considerable patients' interest toward nutritional supplementation - as first-line or adjunctive treatment to PDE5 inhibitors - that goes beyond the measurable increment in penile rigidity" - See propionyl-l-carnitine products at Amazon.com, niacin at Amazon.com and L-arginine products at Amazon.com.
• Relation Between High-Density Lipoprotein Cholesterol and Survival to Age 85 Years in Men (from the VA Normative Aging Study) - Am J Cardiol. 2011 Feb 4 - "We categorized initial HDL cholesterol into <40 mg/dl (reference group), 40 to 49 mg/dl, or ≥50 mg/dl ...

Fully adjusted HR (95% confidence interval) for survival to 85 years of age for participants with an initial HDL cholesterol level ≥50 mg/dl compared to the reference was 0.72 (0.53 to 0.98). Each 10-mg/dl increment in HDL cholesterol was associated with a 14% (HR 0.86, 0.78 to 0.96) decrease in risk of mortality before 85 years of age. In conclusion, after adjusting for other factors associated with longevity, higher HDL cholesterol levels were significantly associated with survival to 85 years of age" - See niacin at Amazon.com (niacin increases HDL).

• High dietary niacin intake is associated with decreased chromosome translocation frequency in airline pilots - Br J Nutr. 2010 Oct 8:1-9 - "Experimental studies suggest that B vitamins such as niacin, folate, riboflavin, vitamin B6 and vitamin B12 may protect against DNA damage induced by ionising radiation (IR) ... We observed a significant inverse association between translocation frequency and dietary intake of niacin (P = 0.02): adjusted rate ratio for subjects in the highest tertile compared with the lowest tertile was 0.58 (95 % CI 0.40, 0.83). Translocation frequency was not associated with total niacin intake from food and supplements as well as dietary or total intake of folate, riboflavin or vitamin B6 or B12. However, the adjusted rate ratios were significant for subjects with ≥ median compared with < median intake of whole grains (P = 0.03) and red and processed meat (P = 0.01): 0.69 (95 % CI 0.50, 0.96) and 1.56 (95 % CI 1.13, 2.16), respectively.

• A "Hot" Topic in Dyslipidemia Management--"How to Beat a Flush": Optimizing Niacin Tolerability to Promote Long-term Treatment Adherence and Coronary Disease Prevention - Mayo Clin Proc. 2010 Apr;85(4):365-79 - "Approximately 5% to 20% of patients discontinued treatment because of flushing. Flushing may be minimized by taking niacin with meals (or at bedtime with a low-fat snack), avoiding exacerbating factors (alcohol or hot beverages), and taking 325 mg of aspirin 30 minutes before niacin dosing. The current review advocates an initially slow niacin dose escalation from 0.5 to 1.0 g/d during 8 weeks and then from 1.0 to 2.0 g in a single titration step (if tolerated). Through effective counseling, treatment prophylaxis with aspirin, and careful dose escalation, adherence to niacin treatment can be improved significantly"

• Endothelial-Vasoprotective Effects of High-Density Lipoprotein Are Impaired in Patients With Type 2 Diabetes Mellitus but Are Improved After Extended-Release Niacin Therapy - Circulation. 2009 Dec 21 - "Patients with diabetes were randomized to a 3-month therapy with ER niacin (1500 mg/d) or placebo ... HDL from healthy subjects stimulated endothelial nitric oxide production, reduced endothelial oxidant stress, and improved endothelium-dependent vasodilation and early endothelial progenitor cell-mediated endothelial repair. In contrast, these beneficial endothelial effects of HDL were not observed in HDL from diabetic patients, which suggests markedly impaired endothelial-protective properties of HDL. ER niacin therapy improved the capacity of HDL to stimulate endothelial nitric oxide, to reduce superoxide production, and to promote endothelial progenitor cell-mediated endothelial repair. Further measurements suggested increased lipid oxidation of HDL in diabetic patients, and a reduction after ER niacin therapy ... HDL from patients with type 2 diabetes mellitus and metabolic syndrome has substantially impaired endothelial-protective effects compared with HDL from healthy subjects. ER niacin therapy not only increases HDL plasma levels but markedly improves endothelial-protective functions of HDL in these patients, which is potentially more important" - See niacin at Amazon.com.

• 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"

• 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. CONCLUSION--The SR form of niacin is hepatotoxic and should be restricted from use. The IR niacin is preferred for the management of hypercholesterolemia but can also cause significant adverse effects and should be given only to patients who can be carefully monitored by experienced health professionals."
