Studies suggest that Tart Cherry (Prunus cerras L.) may provide some of the highest levels of Anthocyanins. Anothcyanins are bioactive phyto-oxidants that help support the body’s natural free-radical-scavenaging mechanisms, and have been studied for a wide range of potential health benefits. Nature’s Life® Tart Cherry contains 0.8% of optimal Anthocyanins. Directions. Take one (1) tablet daily with food.
