Many manufacturers make Astaxanthin, including Now Foods, Vitamin World, Puritan's Pride, Inc. and Piping Rock Health Products. Nutrex Hawaii manufacturers a form of the supplement, BioAstin Supreme Hawaiian Astaxanthin, which contains 12 mg Asataxanthin plus 30 IU of vitamin E and 800 mg of extra virgin olive oil.
Astaxanthin is an antioxidant, one of a large group of chemicals called carotenoids, explains WebMD. It occurs naturally in some types of algae and in pink-colored seafood, such as salmon, lobster, trout and shrimp. Also called astaxanthine, astaxantina, beta-carotene, microalgae, microalgue and ovoester, astaxanthin is used to treat Parkinson's disease, Alzheimer's disease, high cholesterol, stroke and age-related macular degeneration, a common cause of blindness in the elderly. Additionally, some people use it to promote recovery after exercise and to improve joint and immune system health, according to Swanson Health Products, an online retailer who sells several brands of the supplement.
Research suggests that BioAstin Astaxanthin helps the symptoms of carpal tunnel syndrome and that some forms of the supplement have improved fertility in men, says WebMD. Early studies also suggest that astaxanthin reduces the symptoms of menopause and the pain of rheumatoid arthritis. However, these early studies are not conclusive evidence of the supplement's effects, WebMD explains. Although the supplement is likely safe for use by most adults, it is not approved for use in pregnant women or those who are breast feeding, according to WebMD.
