Vitamin A is an essential nutrient required for a wealth of biological functions. It belongs to a family of active (directly usable by the body) substances called retinoids that include retinol, retinal, and retinoic acid. Beta-carotene is a carotenoid, known as pro-Vitamin A, which needs to be converted to retinol (active form of Vitamin A) in small intestine and liver to be utilized by the body.

All these forms of Vitamin A contribute to the maintenance of normal vision, skin, and mucous membranes. It helps maintain normal iron metabolism and normal function of the immune system. It is also important in the process of cell specialization. Vitamin A acts as an antioxidant and contributes to the protection of cells from oxidative damage caused by free radicals.

At HealthAid, you will find that all our Multivitamin and single Vitamin supplements contain optimal levels of Vitamin A derived from different sources including retinol, betacarotene, and cod liver oil.
