Astaxanthin is a carotenoid. More specifically, it is grouped within a class of carotenoid molecules called xanthophylls, which also include compounds such as lutein, zeaxanthin, and many others. Lutein and zeaxanthin are nutrients both present in egg yolks and various leafy green vegetables and are important for proper functioning of the retina of the eye. They have also been shown to support your skin and eyes during sun exposure.
Likewise, astaxanthin is an incredibly powerful antioxidant. It has been shown to promote your defenses against the effects of sun exposure, and furthermore to prevent other types of oxidative damage to cells throughout your body. Astaxanthin is naturally found in algae and can be consumed in your diet by eating animals that themselves accumulate astaxanthin from algae. Many different kinds of seafood, including shrimp, krill, lobster, and salmon, are great sources of astaxanthin.
Recently, astaxanthin has also been clinically shown to help prevent the appearance of wrinkles and the signs of aging, and may even make you more attractive.
