What is Vitamin A ?
Vitamin A is a fat soluble vitamin and is therefore easily absorbed into the system. It has 2 forms, retinol and beta-carotene. Vitamin A is a true vitamin, meaning you can only get it from food. Retinol comes mainly from food sources, beta-carotene is an orange plant pigment and is therefore derived from plant sources. The 2 forms have different health benefits. Both are potent antioxidants, but betacarotene is the more potent of the two in this respect.
