Vitamin A
Vitamin A is fat-soluble, stored in body fat. Although not necessary to intake every day, Vitamin A is vital to the body. 90% of it is stored in liver. Vitamin A is found in two forms - Retinol (preformed Vitamin A) or Retinoids (beta-carotene).
Beta-carotene is a precursor to Vitamin A, formed in the intestine, liver, and kidneys. Beta-carotene is found in deep-yellow and deep-green leafy vegetables. Vitamin A is found in fish liver oils, egg yolk, liver, and fortified foods such as milk or margarine.
Vitamin A is required for synthesis of photoreceptor pigments of rods and cones, the integrity of skin and mucosae, normal tooth and bone development; normal reproductive capabilities; and has important antioxidant properties. It helps form the substance rhodopsin, which is necessary for good vision. Vitamin A also helps keep the membranes, inner linings, tissues, the skin, and eyes in good health. It also helps to energize cells in the immune system and acts as an antioxidant.
