In the 1990s resveratrol emerged as the most promising healthy supplement when it was found to impact sirtuin the “longevity gene.” Because it was first discovered in red wine this effect became known as “the red wine paradox.” Scientists have since learned that a) resveratrol is not the only compound in red wine (or grape seeds) that has a positive impact on human health and b) that grape seeds are not the only source of resveratrol.Swanson Ultra Resveratrol & Quercetin combines pure resveratrol from Japanese knotweed (Polygonum cuspidatum) with a complete grape seed extract standardized to 90% polyphenols (active antioxidant phytonutrients).
