Macular Degeneration Vitamins with Zeaxanthin

VisiVite Plus Formula was the first macular degeneration supplement in the United States Market to include both high dose Lutein and Zeaxanthin.

It has been replaced by VisiVite i-Defense Gold Formula.

Zeaxanthin is one of the two carotenoids contained within the retina.

Within the central macula, zeaxanthin is the dominant component, whereas in the peripheral retina, lutein predominates.

Lutein and zeaxanthin have identical chemical formulas and are isomers, but they are not stereoisomers. The main difference between them is in the location of a double bond in one of the end rings. This difference gives lutein three chiral centers whereas zeaxanthin has two.

As a food additive, zeaxanthin is a food dye with E number E161h.
