Astaxanthin is a naturally occurring carotenoid with a reddish-orange pigment found inĀ different marine algae species and wild berries, and it has demonstrated biological activity both in vitro and in vivo. It is chemically known as 3,3ā²-dihydroxy-Ī²,Ī²-carotene-4,4ā²-dione and has geometric and optical isomers that all exist widely in nature. Animals that consume these astanxanthin-producing organisms often exhibit a reddish-hue with some popular examples being salmon and lobster. As the compound has strong antioxidant and anti-inflammatory properties, astaxanthin has received growing interest as a valuable antiging ingredient in both nutraceuticals and cosmeceuticals.Ā
