Vitamin C + Vitamin E + Lutein + Copper + Zinc

This capsule contains the antioxidant vitamins C and E, the minerals zinc and copper, and lutein, and it is taken by mouth. The mix is made up of essential antioxidant vitamins, minerals and lutein.

Vitamin C is found in the lens of the eye at a much higher concentration than in blood. Long term use of a Vitamin C supplement (10+ years) has been associated with a reduced risk of cataract. It also has an important role in scavenging harmful free radicals. For Vitamin E, one study found that high serum Vitamin E concentrations were associated with a reduced risk of cataract, though the exact mechanism of action is still not established.

Lutein is a carotenoid that is especially concentrated in the macula. Clinical and animal data indicate that it could protect the macula from oxidative or light damage. The mechanism of action is not clear, but one large study found that high levels of dietary lutein are associated with a relatively lower risk of AMD (Age-Related Macular Degeneration, a condition where fine visual activity is lost).

Zinc is an essential trace element and is involved in many enzyme systems. Less severe deficiency shows up as distorted or absent perception of taste and smell, and poor wound healing. Severe deficiency causes skin lesions, alopecia, diarrhea, increased susceptibility to infection and failure to thrive in children.

Copper plays an important role in growth, skeletal integrity and the development of the nervous system. It is part of various enzymes, so it takes part in numerous metabolic conversions.
