Solgar proudly introduces Resveratrol 100 mg Vegetable Capsules. Each capsule provides 200 mg of Polygonum cuspidatum, supplying 100 mg of resveratrol to support healthy biomarkers and improve quality of life. Resveratrol is an antioxidant polyphenol. First isolated in grape skins, it also occurs in peanuts and some herbs, including Polygonum cuspidatum. In recent years, the scientific anti-aging community discovered a family of genes in mammals called SIR (in lower animals) or SIRT (in mammals) encoding for proteins called sirtuins. These proteins were shown to improve quality of life under conditions of caloric restriction. Since severe caloric restriction is not a sustainable or ideal practice for humans, researchers began searching for natural products that could turn on SIRT genes. They discovered that resveratrol could mimic the positive effects of caloric restriction. Additional studies showed that even with high calorie diets, resveratrol turned on SIRT genes, which supported healthy biomarkers such as increased insulin sensitivity and balanced blood sugar that are usually compromised with high calorie diets. While research in humans is ongoing, this incoming data shows great promise. Previous studies have shown resveratrol is cardioprotective. Resveratrol 100 mg contains naturally-derived resveratrol from Polygonum cuspidatum. Each capsule delivers 100 mg of resveratrol, higher than most products on the market. Research suggests that higher doses are efficacious for the support of healthy biomarkers and improved quality of life.
