Astaxanthin Is a Naturally Occurring Carotenoid
Astaxanthin is a xanthophyll carotenoid found in various microorganisms and marine animals. Natural astaxanthin used in AstaMed MYOTM comes from the extract of Haematococcus pluvialis algae which contains astaxanthin esters.
When a shrimp is cooked, it suddenly turns red. That pigment is the astaxanthin that imprints salmon, crabs, krill, lobsters, and even flamingos with a vivid reddish coloration.
Salmon obtains astaxanthin by eating shrimp, and shrimp obtains it by eating microalgae. The microalgae produces astaxanthin when exposed to harsh environmental conditions, in order to protect its nuclear DNA and lipids.
Membranes are not only the gate-keepers of the cell but also of aging factors because they regulate intercellular communication, facilitate cell nutrition, and protect DNA from damage. Astaxanthin has a unique molecular structure that can span the double layer of the cell membrane. Therefore, astaxanthin can exert its antioxidant effect both inside and outside the membranes, which differentiates it from other antioxidants, such as vitamin C, vitamin E, and beta carotene.
Astaxanthin's unique molecular structure and strong anti-oxidative capability has been shown to scavenge peroxyl radicals and quench singlet oxygen, thereby inhibiting the damage of proteins, lipids and DNA, and preventing a chain reaction of lipid peroxidation.

Astaxanthin Protects Mitochondrial Function
Studies have shown that astaxanthin exerts a positive effect on mitochondrial function, as demonstrated by stronger membrane integrity and stimulation of mitochondrial respiration. It means that astaxanthin helps maintain homeostasis of the mitochondrial redox state, and promotes functional integrity in the presence of oxidative stress.
