Astaxanthin is a naturally occurring carotenoid that because of its unique structure, provides a wide range of antioxidant benefits.  Because Astaxanthin is able to cross the blood-brain and blood-retina barriers, it can deliver potent antioxidant protection directly to the eye, brain, and nervous system.  Zanthin® Astaxanthin has been patented for its ability to support retinal and overall ocular health.  Scientific studies have also demonstrated that Astaxanthin can help to support a healthy inflammatory response.
