Vitamin A Supplement Facts & Information
Vitamin A Supplement Guide: The Vitamin That Does It All
1. What is it and where does it come from?
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.
2. What does it do and what scientific studies give evidence to support this?
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 (particularly night 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. It's a good idea to stop free radicals before they stop you.
