Description and Uses

Carotenoid pigment found mostly in animal organisms, but also occuring in plants; thought to be the precursor of astacin. Animal studies indicate that it reduces blood glucose and ameliorates several parameters of the diabetic metabolic syndrome. It improves blood flow and vascular tone in models of hypertension.
