Our aim is to assist the research community by providing a summary of the current clinical knowledge available on resveratrol so that future studies can properly orient their goals. Our body produces the antioxidants and free radicals naturally to fight those damaging effects. 70 On the other hand, when patients were treated with high doses of resveratrol for longer periods of time, no beneficial effect could be observed. Some research shows that resveratrol could be linked to a lower risk of inflammation and blood clotting, which can lower your risk of heart disease. Hopefully the news here will bring the price down for consumers who wish to purchase resveratrol. 48 The study showed that resveratrol improved the outcome for patients receiving delayed r-tpa treatment. Indeed, trans-resveratrol appears to be well absorbed by humans when taken orally, but it’s bioavailability is relatively low due to it’s rapid metabolism and elimination.
There is an interesting correlation among dietary polyphenols pro-oxidant and cytotoxic activities, such as to resveratrol. Resveratrol benefits – our premium, high potency resveratrol is a powerful anti-oxidant to help fight aging, improve cardiovascular health, and even help reduce inflammation. Both cis- and trans-resveratrol also occur as glucosides, i. Doses as low as 10 mg/day of resveratrol also resulted in lower insulin resistance in a four-week, randomized, placebo-controlled study in 19 male subjects with type 2 diabetes. And, because dietary supplements are loosely regulated, it should not be assumed that the labeled dosage is accurate. Laboratory research has also shown antioxidant, anti-inflammatory, anticancer, and other effects. They found that although fasting plasma glucose was unchanged with resveratrol treatment, peak postmeal glucose and 3-h glucose declined. Resveratrol has mild estrogenic activity and until more is known, women with cancers and other conditions that are estrogen sensitive should seek medical advice before taking resveratrol.
And how the antioxidants must be taken, through food or as nutritional supplements? The relative importance of the antioxidant and pro-oxidant activities of antioxidants is an area of current research, but vitamin c, which exerts it’s effects as a vitamin by oxidizing polypeptides, appears to have a mostly antioxidant action in the human body. Anti-proliferative effect of resveratrol, a natural component of grapes and wine, on human colonic cancer cells. The authors suggested that this could be related to the strong antioxidant properties of this polyphenol powerhouse. Present data suggest that the consumption of individual dietary supplements does not enhance the health or longevity of healthy rodents or humans. Certain plants produce resveratrol and other stilbenoids in response to stress, injury, fungal infection, or ultraviolet (Uv) radiation. Because of it’s anti-coagulant properties, the antioxidant could interact poorly with blood thinners and over-the-counter painkillers like aspirin and ibuprofen. This antioxidant can help promote eye and heart health and may play a role in preventing some cancers.
