Healthy Origins® Quercetin Phytosome features Quercefit®, a patented, clinically studied and bioenhanced form of quercetin that has shown up to 20 times more bioavailability than standard quercetin extract. The health benefits of consuming quercetin have been recognized for ages but unlocking these benefits for the body had always been a major hurdle due to quercetin's poor systemic bioavailability. Using Indena's proprietary Phytosome™ technology that was developed in the 1980s, researchers were able to dramatically enhance the bioavailability of quercetin in the body. Healthy Origins® Quercetin Phytosome supports respiratory health, immune health, and optimal exercise performance. *
