Lutein is a yellow-to-orange colored pigment that’s related to vitamin A. Lutein is concentrated in the retina of the eye making it a necessary component of healthy vision. It also works as an antioxidant to reduce the damage done by free radicals and may support blood vessel health.
Zeaxanthin is a bioflavonoid pigment whose benefits include keeping the eye healthy by increasing the level of the macular pigment in the eye. The macular pigment degenerates with age, but it increases by ingesting zeaxanthin.
Recent epidemiological and controlled clinical studies indicate that dietary lutein and zeaxanthin may be of benefit in maintaining both cognitive function and visual health.
Lutein and Zeaxanthin
• Lutein and Zeaxanthin are members of the carotenoid family, which are naturally present in the macula of the retina and lens of eyes
• Lutein and Zeaxanthin serve as accessory light-gathering pigments thereby protecting the eye against the toxic effects of ultra-violet radiation and oxygen
• The protective effect is due in part to the antioxidant (reactive oxygen species quenching) ability of Lutein and Zeaxanthin
• Lutein and Zeaxanthin are the only two carotenoids found in animal lenses and may protect them from age-related diseases affecting lens density and cataract formation
