Meso-astaxanthin is one of three naturally occurring optical isomers of astaxanthin. Astaxanthins are a group of compounds providing red pigmentation in trout, salmon, lobster, shrimp and other sea creatures. Synthetic astraxanthins and biomass containing astraxanthins are used as feed additives in commercial fishing operations to ensure redness of the flesh. Astaxanthins as a group also exhibit antioxidant properties and are marketed in a number of nutriceutical products for human consumption. Isomers astaxanthin including meso-astaxanthin has demonstrated the ability to slow the growth of colon cancer cells in vitro.
