Jamieson Resveratrol Red Wine Extract contains an combination of two ingredients - grapeseed-phosphatidylcholine complex and resveratrol extract. Together, they provide antioxidant support for cardiovascular health. Derived from French and Italian red wine grapes, these natural ingredients provide all of the health benefits of red wine without the calories or alcohol. Jamieson Laboratories' ground-breaking anti-aging and heart-healthy formula is made from two naturally sourced active ingredients - resveratrol and grapeseed. Resveratrol naturally occurs in grapes, mulberries and peanuts, where it guards against bacteria and fungi. Research on resveratrol's effects on human health indicate that many of the benefits associated with red wine are, in fact, the result of this natural antioxidant found in red wine grapes.
