Astaxanthin is a naturally occurring carotenoid with a unique structure that is known to be a potent free
radical scavenger. Because Astaxanthin freely crosses the blood-brain and blood-retina barriers, it can
neutralize free radicals in the eye and central nervous system. Scientific studies also demonstrate
that astaxanthin can support the bodys healthy and balanced immune system responses.
This NOW product features Zanthin, which can help to support overall ocular
