For example, research supports taking 15,000 IU per day of Vitamin A for those with Retinitis Pigmentosa. Vitamin A is a necessary structural component of rhodopsin or visual purple, the light sensitive pigment within rod and cone cells of the retina. If inadequate quantities of vitamin A are present, vision is impaired. The 11-cis retinal form of vitamin A is essential for the neural transmission of light into vision. A deficiency of vitamin A causes a deficit in the pigment needed by rod cells (responsible for our night vision). As a result, if fewer rod cells are able to sufficiently respond in darker conditions, night blindness can result. Betacarotene is the water-soluble version of vitamin A (which is fat soluble), and can be converted to Vitamin A by the body as needed. Food sources for betacarotene include yellow and orange vegetables, including yams, carrots and sweet potatoes, asparagus, spinach, butternut squash, kale, bok choy, mangoes, cataloupe and apricots. Top sources of vitamin A include: beef liver, egg yolk, cheddar cheese and fortified milk.
