Pure natural haematococcus pluvialis extract astaxanthin

Astaxanthin is a keto-carotenoid. Like many carotenoids, astaxanthin is a lipid-soluble pigment. Astaxanthin is found in microalgae, yeast, salmon, trout, krill, shrimp, crayfish, crustaceans, and the feathers of some birds. It provides the red-orange color of salmon meat and the red color of cooked shellfish. The structure of astaxanthin by synthesis was described in 1975. Astaxanthin, unlike several carotenes and one other known carotenoid, is not converted to vitamin A (retinol) in the human body. Like other carotenoids, astaxanthin has self-limited absorption orally and such low toxicity by mouth that no toxic syndrome is known. In vitro, it is an antioxidant with a slightly lower antioxidant activity in some model systems than other carotenoids. Astaxanthin can be used as a dietary supplement intended for human, animal, and aquaculture consumption.
