Vitamin A was given the 1st letter on the alphabet for a name since it was the first vitamin to be discovered. It was found that vitamin A has actually several uses in our bodies including keeping eyes healthy, aiding cell growth as well as helping boost the immune system. However, vitamin A is not just absorbed directly but additionally it is created by the body by converting beta carotene into vitamin A.
Vitamin A itself is found in several foods like eggs, milk, liver and meat.

Beta carotene is not only used to form vitamin A, but it’s also a powerful antioxidant in itself.
