Supplementing with antioxidants has become very popular in the health world, and some of the best antioxidants come from astaxanthin supplements.

Astaxanthin is a red colored carotenoid that can be found in sea algae or krill. It is similar to Vitamin A, and it can also be found in the fish that feed on sea algae, like shrimp and salmon. Astaxanthin is largely responsible for giving these fish their red color.
