Recent research has shown that Resveratrol can help to support healthy cardiovascular function. Resveratrol is best known for its cellular anti-aging properties, as well as for its ability to promote a healthy response to normal biological stress. To complement the activities of Trans-Resveratrol, this product includes proanthocyanidins (OPCs) from grape seed extract and catechins from green tea extract.

Resveratrol, Antioxidants, Supplements

Although antioxidants obtained through diet are considered safe, robust data are lacking to support use of supplemental forms for cancer prevention. Resveratrol has received widespread attention as a possible anti-aging compound and is now widely available as a dietary supplement; much has been made of it’s role in explaining the cardiovascular health benefits of red wine, and other foods. Plus you get all the other healthful plant products that come with the resveratrol. They found that although fasting plasma glucose was unchanged with resveratrol treatment, peak postmeal glucose and 3-h glucose declined. Collagen is one of the most popular supplements on the market these days. A meta-analysis of placebo-controlled clinical trials indicated that resveratrol treatment has negligible effects on attenuating nafld, given the small improvement in nafld features. As many studies reported an inverse correlation between systemic levels of antioxidants and several diseases, primarily cardiovascular diseases, but also diabetes and neurological disorders, antioxidant supplementation has been foreseen as an effective preventive and therapeutic intervention for aging-associated pathologies. This is due to many aspects among which the often-limited statistic power of the studies, the patient genetic background, the bioavailability of the molecules used, and the non-specific effects that antioxidants might have in the human body, should be taken into account.

Thus, adding resveratrol to standard lipid-lowering medication may help restoring normal lipid profile values in these patients (Figure 1). In another study that investigated the compound’s role in managing hay fever, two sprays of a 0,1 percent resveratrol nasal spray into each nostril three times/day for up to four weeks. A review by the independent consumerlab found that one brand cost just 15 cents per 100 milligrams of resveratrol, while another cost $2,76 per 100 milligrams. Another study showed that grapeseed proanthocyanidins together with resveratrol can inhibit breast cancer cells through a variety of mechanisms. A decreased occurrence of microglial activation and astrocyte hypertrophy was also reported in healthy aged rats treated with resveratrol. Determined that resveratrol effectively reduces diastolic blood pressure in conjunction with other phytochemicals such as grape seed extract, green tea supplements and quercetin. A third study found that the bioavailability of supplemental resveratrol was reduced by the amount of fat in the diet, but not by the co-administration of quercetin (Another polyphenol) or alcohol. The low bioavailability of resveratrol reported in human studies limits the clinical evaluation of possible systemic health effects of resveratrol in humans (See metabolism and bioavailability).

Further evaluations are needed before declaring resveratrol as a beneficial compound for human health. 71 All together, these studies seem to show that while resveratrol might be a promising treatment for patients with nafld, it might be most effective under certain conditions, and perhaps mostly as a supplement to recommended lifestyle changes. Clinical studies have yet to determine if resveratrol affects autoimmunity, neurotransmitters, pain, and vitamin d sensitivity. As a natural food ingredient, numerous studies have demonstrated that resveratrol possesses a very high antioxidant potential. Effect of resveratrol on blood pressure: A meta-analysis of randomized controlled trials. 49 Because of it’s anti-inflammatory and anti-oxidative properties, resveratrol has been suggested to promote cardiovascular health, and has therefore been extensively studied as a treatment for prevalent cardiovascular diseases. In the hundreds of articles that i have reviewed on resveratrol’s benefits for cardiovascular disease, cancer, arthritis, glaucoma, cataracts, osteoporosis, high blood pressure, alzheimer’s disease, and many of the other conditions reviewed above, one of the most interesting findings was that this polyphenol has anti-aging benefits.

Also, in another study, aiming to compare resveratrol effects on aging-induced and re-nutrition-induced insulin resistance and it’s consequences on arterial system, the authors found that resveratrol improved insulin sensitivity in old mice fed standard diet, while did not improve insulin resistance status in old mice receiving high-protein diets. In mice, resveratrol applied to the skin before uvb exposure prevented skin cancers. Furthermore, a cross-sectional analysis of patients with prostate cancer showed that selenium levels may influence the risk of aggressive prostate cancer and supplementation may increase prostate cancer mortality. What are the benefits of taking resveratrol? Comparison of changes between baseline and end-of-study measures between placebo and intervention groups showed that resveratrol significantly lowered both fasting glucose and fasting insulin concentrations and improved measures of glycemic control (Hba1c level) and insulin sensitivity (Homa-ir). While red wine is one of the most famous sources of resveratrol, there are other sources such as grapes, blueberries, raspberries, mulberries, and even peanuts. An in-vitro dose-dependent antiviral effect of resveratrol and oxyresveratrol (Extracted from mulberry twigs) showed the antiviral activities of these compounds on african swine fever virus (Asfv). One explanation for how resveratrol works is that it may stop a certain enzyme from turning glucose into sorbitol, a sugar alcohol.

Also found that resveratrol did not cause any changes in glp-1 or gip levels in diabetes patients. These antioxidants can be found in vitamins a, c and e, in the minerals selenium, zinc and copper, and can also be found in phytochemicals from plants, fruits and vegetables. Always consult your health care provider before taking any supplements. One study showed that ultraviolet irradiation to cis-resveratrol induces further photochemical reaction, producing a fluorescent molecule named resveratrone. For example, our group has found resveratrol to be a potent complement to mtor inhibitors in diseases affected by mtor hyperactivation. The levels of resveratrol found in food varies considerably, even in the same food from season to season and batch to batch. It is therefore, important that resveratrol be investigated further for the prophylactic treatment of osteoarthritis in humans and companion animals. By becoming an examine plus member, you will have access to all of the latest nutrition research on over 300 supplements across over 500 different health goals, outcomes, conditions, and more. Aside from it’s indirect antioxidant effects on inflammation, resveratrol is theorized to affect specific inflammatory processes.

Because of it’s anti-coagulant properties, the antioxidant could interact poorly with blood thinners and over-the-counter painkillers like aspirin and ibuprofen. Once absorbed, resveratrol is rapidly metabolized by conjugation to glucuronic acid and/or sulfate, forming resveratrol glucuronides, sulfates, and/or sulfoglucuronides. In preclinical studies, resveratrol has been shown to possess numerous biological activities, which could possibly be applied to the prevention and/or treatment of cancer, cardiovascular disease, and neurodegenerative diseases. Additionally, the metabolites of resveratrol should be studied as well, since some of them have been shown to have anticancer activities. Even more exciting is evidence pointing to anti-cancer properties of resveratrol. In contrast, resveratrol exhibited deleterious effects by increasing inflammation state and superoxide production and decreasing aortic distensibility. In laboratory animals, benefits of resveratrol comprise antitumor effects while in cats it has shown to improve hepatic function. In some cell types, resveratrol acted as a super agonist, whereas in other ones, it produced an equal to or lesser activation than that of estradiol, and as an antagonist at higher concentrations.

Research has shown some therapeutic effects of resveratrol ranging from antioxidant, anti-inflammatory, cardioprotective, antiatherogenic, antiaging, antiplatelet aggregation, anticancer, antidiabetic, antitumor, and immunomodulatory activities. Additional experimental research is needed to confirm and clarify the benefits of collagen and resveratrol supplementation in the prevention and management of aging skin and overall physical and psychological health. Two randomized, placebo-controlled trials reported that one-year consumption of a grape supplement containing 8 mg/day of resveratrol improved inflammatory and atherogenic status in subjects at risk for cardiovascular disease, as well as in patients with established coronary heart disease. Foodpharmacy Blog found the daily suggested dosage among resveratrol products to range from 50 to 1,020 mg of resveratrol. In rodent models, resveratrol has been shown to upregulate glp-1 and lower glycemia, but thazhath et al. The biological significance of resveratrol has been primarily investigated in test tubes and cultured cells, and to a lesser extent, in animal models. A team of researchers studied the mechanisms of action of resveratrol using a cat model. The evaluations at 6 months and 12 months did not indicate significant differences between the two batches with different doses of resveratrol on the effect on bp.

Pterostilbene is a methoxylated derivative of resveratrol that showed antibacterial activity against drug-resistant staphylococcus aureus (Mrsa) with minimum inhibitory concentration (Mic) superior of pterostilbene compared to resveratrol (8 16-Fold). In fact, there was no link between resveratrol levels and the rates of heart disease, cancer, and death. In the end, taking artificial antioxidant supplements may do you and your body more harm than good. In diabetic patients, resveratrol was able to increase insulin sensitivity, decrease blood glucose levels, and positively regulate several other biomarkers associated with diabetes.

Resistance against oxidative stress-related damage in primary neuronal cells treated with resveratrol has been associated with the induction of heme oxygenase-1 (Ho-1), an enzyme that degrades pro-oxidant heme. And there are some cautions, especially regarding how resveratrol could interact with other medications.
