Luetin is an antioxidant carotenoid that occurs in nature with zeaxanthin, a closely related carotenoid. Lutein and zeaxanthin concentrate in the eye's macula and lens, as well as in the skin, breast and cervical tissues. Both lutein and zeaxanthin protect the macula from degradation normally associated with aging and oxidative stress. The macula is responsible for focus and color differentiation. Lutein and zeaxanthin are found in dark green, leafy vegetables. While the average American intake of Luetin is only 2 mg per day, other population groups consume from 6 to 20 mg per day.

LuteinSorb is a patent-pending delivery of free lutein as a dispersion of lutein laid onto a hydrophilic carrier consisting of marigold (Tagetes species) fractions - all materials GMO-free. The particle size of the lutein active ingredient is reduced to a molecular level, which results in a 6 times greater absorption of lutein.
