Astaxanthin, a naturally occurring carotenoid pigment, is a powerful biological antioxidant. Astaxanthin exhibits strong free radical scavenging activity and protects against lipid peroxidation and oxidative damage of LDL-cholesterol, cell membranes, cells, and tissues. Astaxanthin has been the focus of a large and growing number of peer-reviewed scientific publications.

Astaxanthin plays many important biological functions in these species, including:
Improved protection against oxidation and photo-oxidation
Reproduction and development
Immune response
Resistance to disease
Reproductive behaviour
Communication.
