Astaxanthin is a carotenoid with unique cell membrane antioxidant functions. According to a growing body of scientific evidence, astaxanthin plays a role in supporting eye and heart health. Astaxanthin is not made in the human body and is currently obtained almost exclusively from dietary sources such as salmon and crustaceans. Its intense red color contributes to the color pigmentation of salmon, shrimp, crabs and other marine life.
Due to astaxanthin’s unique molecular structure, position and distribution within cell membranes and lipoproteins, astaxanthin has been the focus of many clinical studies assessing its ability to support eye and heart health.
