Vitamin A: is a fat-soluble vitamin, meaning that it requires fats or oils for your body to absorb it. Excess amounts are usually stored in the liver. Vitamin A is needed for healthy hair, skin and bones. Vitamin A works together with Vitamins D, B, E, zinc, phosphorus and calcium. Vitamin A is an essential vitamin that the body needs to stay healthy.

While vitamin A is best known for its vital role in vision, this vitamin also participates in physiological activities related to the immune system, maintenance of epithelial and mucosal tissues, growth, reproduction, and bone development. In food, vitamin A typically occurs as a fat compound called retinyl palmitate. The body converts retinyl palmitate to three metabolically active forms of the vitamin: retinol, retinal, and retinoic acid.
