MASS SPEC Documentation Lab Tested

Lutein is the principal carotenoid concentrated in the macula, the central area of the retina responsible for vision. Lutein and companion carotenoid zeaxanthin work in synergy to provide nutritional support to our eyes and skin* – the only organs of the body directly exposed to the outside environment. Their primary role is to provide antioxidant protection against sunlight-induced free radical damage*.

Manufactured by Natural Factors to ensure safety and potency in accordance with Good Manufacturing Practices (GMP) of the FDA and Health Canada.

For freshness, store in a cool, dry place.
