Zeaxanthin Product Information
Zeaxanthin is suggested in peer-reviewed literature to be the central macula preference over lutein. Dietary and supplemental Zeaxanthin is preferentially deposited at the center of the macula. If the diet is deficient in zeaxanthin, which most diets are, and supplemental zeaxanthin is not available, the macula preference for zeaxanthin is so strong the body will convert a small amount of dietary lutein to a similar molecule called meso-zeaxanthin in an attempt to supply the eye with pigment that best protects the macula. Meso zeaxanthin is not found anywhere in the body, except in the eye.
Ingredient Rationale for Zeaxanthin-4
Studies on sports performance have now been done on baseball players and young adults that clearly suggest zeaxanthin, and lutein to a lesser extent supports visual performance in athletics.
Beta-carotene has the ability to convert to retinol, if the vitamin A liver stores are deficient, which they are in many older people. Vitamin A deficiency can be responsible for night driving problems in the older population.
Unfortunately, unlike beta-carotene, zeaxanthin and lutein have almost no ability to convert to Vitamin A retinol, so the science behind the substitution is a bit flawed - since Vitamin A retinol is vital to the health of the retina, specifically the rods and cones.
The best solution: supplement with biochemically balanced amounts of zeaxanthin, lutein, and vitamin A as retinyl palmitate, in a full-spectrum supplement. Additional zeaxanthin or lutein supplementation should be the decision of the consumer and his or her eye care professional.
