Mankind's quest for longevity shows no signs of abating as we continue to find better ways to keep ourselves healthier for longer. 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). Then, we amplify the free-radical-fighting power with quercetin, a flavonoid known to fight free radicals and defend cells from within. For purity and performance in your antioxidant supplementation, chose Swanson Ultra Resveratrol & Quercetin, the supplement that combines today's most popular, clinically researched antioxidants for longevity in an affordable daily capsule you can take with confidence.
