Astaxanthin is a red pigment that belongs to a group of chemicals called carotenoids. It occurs in certain algae and causes the pink-red color in salmon. Astaxanthin is the strongest antioxidant found in nature. Its antioxidant activity is 550 times that of vitamin E and 10 times that of beta-carotene, so it is known as the "king of antioxidants"! This effect might protect cells from damage. Astaxanthin might also improve the way the immune system functions. People use astaxanthin for many purposes, including Alzheimer disease, athletic performance, aging skin, muscle soreness from exercise, and many others.
