A powerful, natural antioxidant, resveratrol is found in the fruits and seeds of certain plants, including grapes and grape-derived products like red wine, along with the herb Polygonum cuspidatum. Resveratrol is believed to be one of the forces of “the French Paradox,” the apparent contradiction wherein French people ate high fat diets but had good cardiovascular health. Scientists believe their moderate drinking of red wine reduced the risk of heart disease. Along with promoting cardiovascular health and healthy lipid levels, resveratrol also supports the immune system and has anti-aging benefits. Swanson Ultra carries a variety of resveratrol potencies, including 50 mg, 100 mg and more. Swanson Ultra Resveratrol Complex combines red wine extract, grapeseed and resveratrol from Polygonum cuspidatum for a powerful antioxidant blend.
