Were you looking for information about Vitamin A? Vitmin A is a common misspelling of vitamin A.
 
There are two main types of vitamin A; one comes from animal sources (retinoids) and the other comes from plant sources (carotenoids). The fat-soluble vitamin helps control the genes for numerous different structural proteins, such as certain important proteins in the skin, and is used for the transduction of light into nerve signals that are essential for vision. While most people do not experience problems with vitamin A supplementation, potential side effects include dizziness, liver problems, and headaches.
