High levels of zeaxanthin found in eye tissue are linked to better vision, especially in dim lighting. Zeaxanthin also protects the eyes from diseases caused by aging. Supplements containing zeaxanthin have been shown to slow the progression of macular degeneration.

Astaxanthin reduces oxidation in the body, which plays a role in preventing health issues such as cancer, heart disease, Alzheimer's or Parkinson's disease, says WebMD.

This powerful antioxidant also has anti-inflammatory properties and can assist with treating rheumatoid arthritis and carpal tunnel syndrome. More research is required on this antioxidant before appropriate doses can be recommended. Astaxanthin is mostly found in specific types of marine algae but can also be found in salmon, rainbow trout, shrimp and lobster.
