It belongs to a larger class of phytochemicals known as terpenes. It is classified as a xanthophyll, which means "yellow leaves". Like many carotenoids, it is a colorful, lipid-soluble pigment. Astaxanthin is produced by microalgae, yeast, salmon, trout, krill, shrimp, crayfish, crustaceans, and the feathers of some birds. While astaxanthin is a natural nutritional component, it can be found as a food supplement. The supplement is intended for human, animal, and aquaculture consumption. The commercial production of astaxanthin comes from both natural and synthetic sources. The U.S. Food and Drug Administration (FDA) approved astaxanthin (See: Regulations below) as a food coloring (or color additive) for specific uses in animal and fish foods. The European Union (actually European Commission) considers it food dye within the E number system, E161. In 1948, Nobel prizewinner George Wald surmized, "This could lead to an important new use of astaxanthin as a drug delivery for medicines that are insoluble in water, and give designers of new food colourants or dyestuffs an interesting new capability." Astaxanthin is used as a feed supplement for salmon, crabs, shrimp, chickens and egg production. Regardless of the source, astaxanthin provides some important benefits beyond coloration. It also has been found to be essential for proper growth and survival. For seafood and animals: The primary use of synthetic astaxanthin today is as an animal feed additive to impart coloration, this includes farm-raised salmon and egg yolks. In that, synthetic carotenoid (i.e., coloured yellow, red or orange) pigments represent about 15-25% of the cost of production of commercial salmon feed. Today, essentially all commercial astaxanthin for aquaculture is produced synthetically from petrochemical sources, with an annual turnover of over $200 million, and a selling price of ~$2000 per kilo of pure astaxanthin. 30 dys money back guarantee.
