Solgar® Astaxanthin 5 mg contains astaxanthin, a type of carotenoid, which is a natural pigment found in various foods. Carotenes are found specifically in vegetables and fruits, and beta-carotene in orange or dark green fruits. Astaxanthin is responsible for the intense reddish-orange color of lobster, salmon, some algae and is the pinkish-red pigment that gives flamingos their characteristic color. Astaxanthin is a carotenoid belonging to the group of carotenoids called xanthophylls and unlike other carotenoids, found in plants, astaxanthin is more widely distributed in marine organisms, which obtain it through the consumption of microalgae.
