Vitamin A has several important functions in the body, including the maintenance of proper vision. When the body is deficient in Vitamin A, the eye gradually loses its ability to adapt to changes in light resulting in "Night Blindness." Another vital role of vitamin A concerns the formation, maintenance, and growth of skin, which forms the body's primary barrier to infection. Do not take if you are pregnant or planning to become pregnant.
WARNING: Taking vitamin A from retinol in quantities of 10,000 IU or more is known to cause birth defects or other reproductive harm.
