Superior Bioavailability of a Novel Lutein and Zeaxanthin Formulation in Healthy Human Subjects.

Introduction: Lutein (L) and zeaxanthin (Z) are carotenoids that are found in the macula of the human eye and are known to improve visual functions. However, poor bioavailability of supplemental L and Z poses a challenge to achieving significant benefits after consumption. We developed a novel patented formulation of L and Z (Ocusorb) and demonstrated the improved bioavailability in a pharmacokinetic clinical study.
