Zinc (citrate)

Highly bioavailable form of zinc for eye health

Zinc is a constituent of over two dozen enzymatic reactions in the body, two of which are within the retina. A concentrated pool of zinc exists in the retina and is used to support the rhodopsin-opsin cycle for healthy night vision and synaptic transmission of nerve impulses to the brain. A pilot trial conducted at the Louisiana State University Medical Center School of Medicine reported that zinc may promote macular health. Another study indicated that zinc supports retinal pigment epithelium (RPE) health. As a component of super oxide dismutase (SOD), zinc promotes cellular antioxidant protection. Zinc has been reported to bind to melanin rich tissues and enhances antioxidant activity in the eyes. A German study explored this theory and obtained data suggesting that irises of a darker pigment might absorb more zinc than those that are lighter. Additionally, zinc plays a fundamental role in collagen formation and healthy tissue development.*

Zinc (citrate) is a highly bioavailable form of zinc important for a wide range of ocular functions.*
