Source Naturals Astaxanthin 2mg, 60 Tablets
Astaxanthin, a member of the carotenoid family, is a powerful antioxidant. In vitro research demonstrates that astaxanthin is ten times stronger in scavenging free radicals than other carotenoids such as lutein, zeaxanthin, and beta-carotene, and one-hundred times stronger than alpha-tocopherol.  Astaxanthin has also been shown to prevent low-density lipoprotein oxidation in human blood and enhance the immune system in animal studies.
