Astaxanthin, which is part of the carotenoid family, is thought to be the most potent antioxidant nature has to offer, and mounting research suggests it has broad-spectrum, system-wide health benefits. It’s derived from Haematococcus microalgae, which produces astaxanthin as a protective mechanism to shield the fragile algae from harsh ultraviolet (UV) light and other environmental stressors. 

Astaxanthin’s benefits are so numerous, I’ve written several articles to cover its activities, from radiation protection, to eye, brain, lung and heart health.

Astaxanthin is related to beta-carotene, lutein and canthaxanthin. However, its unique molecular structure makes it both more potent and unique than other carotenoids. For example, astaxanthin has 550 times stronger antioxidant power than vitamin E, and is 6,000 times more potent than vitamin C. 

The major problem with standard powdered astaxanthin supplements is the low absorption rates after oral consumption.
