Vitaman A
Were you looking for information about Vitamin A? Vitaman A is a common misspelling of vitamin A.
Vitamin A is a fat-soluble vitamin that is essential for many important functions of the body. It is important for a healthy immune system and is also used for the transduction of light into nerve signals that are important for vision. Most people can safely take a multivitamin that contains a little vitamin A, but high-dose supplementation does not appear to be beneficial or safe for most people, except in documented cases of vitamin A deficiency.
