Resveratrol

Specific Recommendations:

News & Research:

  • Resveratrolicon - Vitacost Health Library
  • Plant Antioxidant May Protect Against Radiation Exposure - Science Daily, 9/23/08 - "Resveratrol, the natural antioxidant commonly found in red wine and many plants, may offer protection against radiation exposure ... Currently there are no drugs on the market that protect against or counteract radiation exposure"
  • Resveratrol May Prevent Breast Cancer - WebMD, 7/7/08 - "when the body's system for processing estrogen gets out of balance, dangerous estrogen metabolites appear. These toxic compounds react with DNA in breast cells and jump-start the growth of tumors ... resveratrol decreases the processing of estrogen into these dangerous compounds. Perhaps more importantly, it also blocks interactions between estrogen metabolites and cellular DNA ... And that's not all. Rogan's team finds that resveratrol increases production of an enzyme that destroys dangerous estrogen metabolites" - [Science Daily] - See Jarrow Resveratrol 100 at iHerb.
  • Resveratrol, Found In Red Wine, Wards Off Effects Of Age On Heart, Bones, Eyes And Muscle - Science Daily, 7/3/08 - "This study, conducted and supported in part by the National Institute on Aging (NIA), part of the National Institutes of Health, is a follow-up to 2006 findings that resveratrol improves health and longevity of overweight, aged mice. The report confirms previous results suggesting the compound, found naturally in foods like grapes and nuts, may mimic, in mice, some of the effects of dietary or calorie restriction, the most effective and reproducible way found to date to alleviate age-associated disease in mammals"
  • Fountain of youth? Red wine gives up secrets - MSNBC, 7/3/08 - "Most of mice given resveratrol did not live longer than other mice but were far more healthy in several important measures"
  • Can Red Wine Help You Live Longer? - WebMD, 6/6/08
  • Red Wine's Resveratrol May Help Battle Obesity - Science Daily, 6/16/08 - "resveratrol inhibited the pre-fat cells from increasing and prevented them from converting into mature fat cells. Also, resveratrol hindered fat storage. Most interesting, according to Fischer-Posovszky, was that resveratrol reduced production of certain cytokines (interleukins 6 and 8), substances that may be linked to the development of obesity-related disorders, such as diabetes and clogged coronary arteries. Also, resveratrol stimulated formation of a protein known to decrease the risk of heart attack. Obesity decreases this substance, called adiponectin" - [WebMD]
  • Substance In Red Wine, Resveratrol, Found To Keep Hearts Young - Science Daily, 6/4/08 - "Resveratrol is active in much lower doses than previously thought and mimics a significant fraction of the profile of caloric restriction at the gene expression level ... In animals on a restricted diet, 90 percent of those heart genes experienced altered gene expression profiles, while low doses of resveratrol thwarted age-related change in 92 percent. The new findings, say the study's authors, were associated with prevention of the decline in heart function associated with aging" - See Jarrow Resveratrol 100 at iHerb.
  • Low-dose resveratrol may slow ageing: for mice at least - Nutra USA, 6/4/08 - "animals in the calorie-restriction and low-dose resveratrol groups had altered gene expression profiles in 90 and 92 per cent, respectively, in the heart ... In short, a glass of wine or food or supplements that contain even small doses of resveratrol are likely to represent "a robust intervention in the retardation of cardiac ageing,"" - See Jarrow Resveratrol 100 at iHerb.
  • Red wine may protect heart from aging’s toll - MSNBC - 6/3/08 - "Resveratrol at low doses can retard some aspects of the aging process, including heart aging, and it may do so by mimicking some of the effects of caloric restriction, which is known to retard aging in several tissues and extend life span"
  • Red Wine Could Benefit Patients With Diabetes - Medscape, 5/16/08 - "New research suggests that resveratrol, a chemical commonly found in red wine, has the ability to lower blood-sugar levels, but it might also produce certain unpleasant adverse effects ... The concern is that you could lower glucose in diabetics but at the same time. . . [lower] glucose levels in the brain or in other important tissues" - Does that last part make sense?  Is there anything that selectively lowers blood-sugar, i. e., lowers the blood without the brain?  And isn't it the high blood sugar in the brain that they believe is the reason the Alzheimer's rate is so high in diabetics?  And isn't it the advance glycation end products that are partly responsible for damage to important tissues?  Sounds like a biased article to me.
  • Mounting Evidence Shows Red Wine Antioxidant Kills Cancer - Science Daily, 3/25/08 - "Rochester researchers showed for the first time that a natural antioxidant found in grape skins and red wine can help destroy pancreatic cancer cells by reaching to the cell's core energy source, or mitochondria, and crippling its function ... The new study also showed that when the pancreatic cancer cells were doubly assaulted -- pre-treated with the antioxidant, resveratrol, and irradiated -- the combination induced a type of cell death called apoptosis, an important goal of cancer therapy" - [WebMD]
  • Grape Skin Compound Fights The Complications Of Diabetes - Science Daily, 3/20/08 - "resveratrol, a compound present naturally in grape skin, can protect against the cellular damage to blood vessels caused by high production of glucose in diabetes"
  • Chemical In Red Wine, Fruits And Vegetables Counters Unhealthy Effects Of High-fat Foods - Science Daily, 1/2/08 - "consuming polyphenols (natural compounds in red wine, fruits, and vegetables) simultaneously with high-fat foods may reduce health risks associated with these foods"
  • Wine Compound Spurs Diabetes Research - WebMD, 11/29/07 - "In October, Chinese researchers reported that resveratrol curbs insulin resistance in mice. Insulin is a hormone that controls blood sugar. Insulin resistance can lead to type 2 diabetes ... Like resveratrol, the lab-made chemicals activate a gene called SIRT1, making the diabetic mice more sensitive to insulin ... the newly developed chemicals are 1,000 times more potent than resveratrol"
  • Report: Two resveratrol supplements mislabeled - USATODAY.com, 11/14/07 - "Life Extension Resveratrol Caps are supposed to contain 20 milligrams of resveratrol per capsule but have about 5 milligrams, the report says. Resvert, distributed by SupplementSpot (formerly known as Young Again Nutrients), had only 58% of its promised 25 milligrams of resveratrol per capsule"
  • Resveratrol review - ConsumerLab.com, 11/13/07 - "But ConsumerLab.com found two supplements to provide only 27% and 58% of their listed amounts of resveratrol. A third product boasted several hundred milligrams of a red wine grape complex but actually contained only two milligrams of resveratrol. Across thirteen products, daily doses ranged from just 1 milligram to as much as 1,000 milligrams of resveratrol. Prices ranged several fold" - Note:  I get the paid version and Life Extension® Resveratrol Caps and Resvert™ 100 mg proanthrocyanadins with 25 mg resveratrol were not approved. Jarrow Resveratrol 100™ is what I take and it was approved.
  • Red Wine And Grape Juice Help Defend Against Food-borne Diseases, Study Suggests - Science Daily, 10/11/07
  • Red Wine Compound May Curb Diabetes - WebMD, 10/2/07 - "Resveratrol curbs insulin resistance in mice ... According to our findings, people might need to drink about three liters of red wine each day to get sufficient resveratrol -- about 15 milligrams -- for its biological effects"
  • Red Wine Compound Shown To Prevent Prostate Cancer - Science Daily, 8/31/07 - "n the study resveratrol-fed mice showed an 87 percent reduction in their risk of developing prostate tumors that contained the worst kind of cancer-staging diagnosis ... Other mice in the study, those fed resveratrol but still developed a less-serious form of prostate cancer, were 48 percent more likely to have their tumor growth halted or slowed when compared to mice who did not consume the compound ... A cancer prevention researcher lives for these days when they can make that kind of finding" - See resveratrol products at iHerb.
  • Red Wine Protects The Prostate - Science Daily, 5/25/07 - "men who drink an average of four to seven glasses of red wine per week are only 52% as likely to be diagnosed with prostate cancer as those who do not drink red wine ... when white wine was compared with red, red had the most benefit ... But much of the speculation focuses on chemicals—including various flavonoids and resveratrol—missing from other alcoholic beverages"
  • Resveratrol Content Varies Among Red Wines - Science Daily, 4/19/07
  • Life-extending compound may be great news -- for mice - CNN, 12/21/06 - "In one study, scientists provided mice a high-calorie, high-fat diet and then gave half of the animals resveratrol. At 114 weeks -- old age for mice -- less than a third of the mice taking resveratrol died. More than half of the mice who did not take resveratrol died. In another study, mice who took resveratrol lost weight, increased metabolism and doubled their exercise endurance"

  • Wine Ingredient May Nix Fat's Effects - WebMD, 11/1/06 - "A new study shows obese, middle-aged mice fed a fatty diet supplemented with resveratrol, an antioxidant found in red wine, seemed to be spared most of the unhealthy effects of their extra weight and lived longer than those fed the same fat-laden diet without resveratrol"
  • One for the Ages: A Prescription That May Extend Life - New York Times, 10/31/06 - "One leading candidate, a newly synthesized form of resveratrol — an antioxidant present in large amounts in red wine — is already being tested in patients. It may eventually be the first of a new class of anti-aging drugs. Extrapolating from recent animal findings, Dr. Richard A. Miller, a pathologist at the University of Michigan, estimated that a pill mimicking the effects of calorie restriction might increase human life span to about 112 healthy years"
  • Red Wine vs. Colon Cancer - WebMD, 10/24/06 - "3% of red wine drinkers had such abnormal growths, compared with nearly 9% of white wine drinkers and almost 10% of teetotalers ... they suggest that a compound found in grapes and red wine – the antioxidant resveratrol -- may cut the odds of getting abnormal colon growths that can become cancerous"
  • Resveratrol in red wine could cut colorectal cancer risk - Nutra USA, 10/23/06 - "Drinking more than three glasses of red wine a week could cut the risk of colorectal cancer by almost 70 per cent ... the active component in wine that may be behind the apparent benefits is most likely resveratrol"

Abstracts:

  • Resveratrol, at concentrations attainable with moderate wine consumption, stimulates human platelet nitric oxide production - J Nutr. 2008 Sep;138(9):1602-8 - "resveratrol, at concentrations attainable after moderate wine intake, activates platelet eNOS and in this way blunts the proinflammatory pathway linked to p38MAPK, thus inhibiting ROS production and ultimately platelet function. This activity may contribute to the beneficial effects of moderate wine intake on ischemic cardiovascular disease"
  • Long-term effects of resveratrol supplementation on suppression of atherogenic lesion formation and cholesterol synthesis in apo E-deficient mice - Biochem Biophys Res Commun. 2008 Jul 5 - "The concentration of total-cholesterol (total-C) and LDL-cholesterol (LDL-C) in plasma was significantly lower in the resveratrol-supplemented groups compare to the control group over the entire experimental period. The plasma HDL-C concentration was significantly elevated, and the ratio of HDL-C/total-C was significantly higher in the CF and RV groups than in the control group. Plasma paraoxonase (PON) activity was significantly higher in the 0.06% resveratrol group. The hepatic HMG-CoA reductase (HMGR) activity was significantly lower in the clofibrate and resveratrol groups than in the control group. Resveratrol supplements attenuated the presence of atherosclerotic lesions and periarterial fat deposition in the apo E(-/-) mice. The presence of intracellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1) in atherosclerotic vessels was diminished in the resveratrol-supplemented apo E(-/-) mice. These results provide new insight into the anti-atherogenic and hypocholesterolemic properties of resveratrol in apo E(-/-) mice that were fed a normal diet"
  • Resveratrol reduces endothelial progenitor cells senescence through augmentation of telomerase activity by Akt-dependent mechanisms - Br J Pharmacol. 2008 Jun 30 - "Resveratrol significantly increased telomerase activity and Akt phosphorylation ... Resveratrol delayed the onset of EPC senescence and this effect was accompanied by activation of telomerase through the PI3K-Akt signalling pathway. The inhibition of EPCs senescence by resveratrol might protect EPCs against dysfunction induced by pathological factors in vivo and improve EPC functional activities in a way that may be important for cell therapy"
  • Resveratrol Induces Apoptosis through ROS-Dependent Mitochondria Pathway in HT-29 Human Colorectal Carcinoma Cells - J Agric Food Chem. 2008 Jun 4 - "Results of the present study provide evidence demonstrating the antitumor effect of trans-resveratrol via a ROS-dependent apoptosis pathway in colorectal carcinoma"
  • Antioxidant Protection of Resveratrol and Catechin in Saccharomyces cerevisiae - J Agric Food Chem. 2008 May 20 - "In this work, the capacity of resveratrol and catechin to protect the eukaryotic microorganism Saccharomyces cerevisiae against oxidative stress caused by different agents, hydrogen peroxide, carbon tetrachloride, and cadmium, was evaluated. Under all stress conditions, both polyphenols increased tolerance, although their protection was more evident under peroxide exposure. By using mutant strains deficient in specific antioxidant defense systems (superoxide dismutases, catalase, or glutathione), it was observed that increased H 2O 2 tolerance produced by both polyphenols was associated with catalase, as well as the rise in survival rates caused by resveratrol under CCl 4. The acquisition of tolerance was correlated with a reduction in lipid peroxidation, indicating that the antioxidant property of resveratrol and catechin involves protection against membrane oxidation"
  • Dietary resveratrol administration increases MnSOD expression and activity in mouse brain - Biochem Biophys Res Commun. 2008 May 15 - "trans-Resveratrol (3,4',5-trihydroxystilbene; RES) ... The increase in MnSOD was not due to a substantial proliferation of mitochondria, as RES treatment induced a 10% increase in mitochondrial abundance (Citrate Synthase activity). The potential neuroprotective properties of MnSOD have been well established, and we demonstrate that a dietary delivery of RES is able to increase the expression and activity of this enzyme in vivo"
  • Resveratrol protects against arsenic trioxide-induced cardiotoxicity in vitro and in vivo - Br J Pharmacol. 2008 Mar 10 - "The clinical use of arsenic trioxide (As(2)O(3)), a potent antineoplastic agent, is limited by its severe cardiotoxic effects ... resveratrol significantly attenuated As(2)O(3)-induced QT prolongation, structural abnormalities and oxidative damage in the heart. In H9c2 cardiomyocytes, resveratrol also decreased apoptosis, production of ROS and intracellular calcium mobilization induced by treatment with As(2)O(3). These observations suggested that resveratrol has the potential to protect against cardiotoxicity in As(2)O(3)-exposed patients"
  • Resveratrol attenuates the expression of HMG-CoA reductase mRNA in hamsters - Biochem Biophys Res Commun. 2007 Dec 28 - "The concentrations of serum total cholesterol and triglyceride were significantly lower in the resveratrol-fed group than in the control group. The resveratrol contained diet significantly decreased Apo B, Lp(a), and cholesterol-ester-transport protein (CETP) concentrations, but increased Apo A-I levels and the Apo A-I/Apo B ratio. The contents of cholesterol and triglyceride in hepatic tissue were significantly lower in the resveratrol group than in the control group. Real-time PCR analysis revealed that HMGR mRNA expression was significantly lower in the resveratrol group than in the control group"
  • Differential expression of genes induced by resveratrol in human breast cancer cell lines - Nutr Cancer. 2006;56(2):193-203 - "The phytoalexin, trans-resveratrol (RES), is a polyphenolic compound found in plants and fruits that seems to have a wide spectrum of biological activities. It has been found to possess cancer chemopreventive effects by inhibiting diverse cellular events associated with tumor initiation, promotion, and progression. RES is also a phytoestrogen, which binds to and activates estrogen receptors (ERs) that regulate the transcription of estrogen-responsive target genes"
  • Resveratrol inhibits TNF-alpha-induced changes of adipokines in 3T3-L1 adipocytes  - Biochem Biophys Res Commun. 2007 Oct 26 - "resveratrol may improve obesity-induced cardiovascular disease, particularly atherosclerosis, by attenuating the TNF-alpha-induced changes of adipokines"
  • Hypoxia enhances LPA-induced HIF-1alpha and VEGF expression: Their inhibition by resveratrol - Cancer Lett. 2007 Oct 3 - "Lysophosphatidic acid (LPA) is a bioactive phospholipid that is involved in various cellular events, including tumor invasion and metastasis ... Collectively, these results show that LPA under hypoxic condition enhances cell migration through the sequential induction of HIF-1alpha and VEGF, and that this enhancement is efficiently blocked by resveratrol"
  • Resveratrol Inhibits the Activity of Equine Neutrophil Myeloperoxidase by a Direct Interaction with the Enzyme - J Agric Food Chem. 2007 Sep 11 - "Resveratrol is a polyphenolic antioxidant present in beverage and food known for its multiple protective effects. We report the inhibitory effects of resveratrol on equine myeloperoxidase (MPO), a hemic peroxidase present in the granules of the neutrophils involved in the inflammatory response. Resveratrol inhibited the production of reactive oxygen species (ROS) by stimulated equine neutrophils by acting as a direct scavenger of the ROS released by the cells but did not modify the degranulation of the stimulated neutrophils as the amounts of released MPO were unchanged. Resveratrol strongly inhibited the chlorination, oxidation, and nitration activities of MPO in a dose-dependent manner"
  • Resveratrol inhibits expression and binding activity of the monocyte chemotactic protein-1 receptor, CCR2, on THP-1 monocytes - Atherosclerosis. 2007 May 11 - "Monocyte chemotactic protein-1 and its receptor, CCR2, play a key role in atherosclerosis ... These inhibitory effects of resveratrol on chemokine receptor binding and expression may contribute, in part, to its cardiovascular protective activity in vivo"
  • The cancer preventative agent resveratrol is converted to the anticancer agent piceatannol by the cytochrome P450 enzyme CYP1B1 - Br J Cancer 2002 Mar 4;86(5):774-8 - "This observation provides a novel explanation for the cancer preventative properties of resveratrol. It demonstrates that a natural dietary cancer preventative agent can be converted to a compound with known anticancer activity by an enzyme that is found in human tumours"
