What is vitamin A?
You can get vitamin A by eating a variety of foods. You can find preformed provitamin A. The former are obtained from products of animal origin, the latter from products of plant origin.
These forms of vitamin A are also known as retinols and carotenoids. In fact, some medical experts point out that, once ingested, this vitamin can take three forms: retinol, retinal, and retinoic acid, depending on the body’s needs.
Vitamin A has the function of supporting and improving eyesight, healthy skin and mucous membranes, growth of bones and teeth; as well as the health of the immune system.
