Astaxanthin is a carotenoid – a class of compound that gives foods high colour eg. beetroot, capsicum, carrots, etc. These pigments carry out a variety of important biological functions, are critical to photosynthesis, and protect plants and organisms from damage by light and oxygen. Many animals including humans consume carotenoids to provide them with antioxidants and a source of vitamin A.
Researchers believe that many of the benefits of carotenoids are due to their free-radical fighting potential. Carotenoids act as antioxidants to help combat damage from oxidative stress. They are among the most robust antioxidants nature has to offer.
Astaxanthin is a high-powered antioxidant with a molecular structure that makes it very effective at neutralizing free radicals. Like most carotenoids, its benefits include support for vision, skin, joint and immune health
