Understanding Carotenoids
Astaxanthin is classified as a carotenoid, which is a naturally occurring pigment commonly found in algae, vegetables, and fruits. Unlike other organisms, humans do not have the ability to produce carotenoids on their own. Instead, they must obtain these beneficial compounds through their diet or by taking supplements. Carotenoids, including astaxanthin, function as antioxidants, effectively counteracting the harmful effects caused by free radicals and preventing cell damage.
Sources of Astaxanthin
Astaxanthin, a red-orange pigment, is a member of the carotenoid family, which includes other popular antioxidants such as beta-carotene and lycopene. Originally identified in lobsters, it gained approval as a dietary supplement in 1991. Astaxanthin can be derived from various seafood sources, including krill, shrimp, algae, trout, salmon, and red sea bass.
