Were you looking for information about Vitamin A? Vitamina is a common misspelling of vitamin A.
Vitamin A comes from both animal sources (known as retinoids) and plant sources (known as carotenoids). The fat-soluble vitamin is important for cell growth, good vision, and a healthy immune system. Most people do not experience side effects due to vitamin A supplementation, as long as the maximum dosage is not exceeded. Taking too much, however, can result in significant side effects, such as liver problems, osteoporosis, and peeling of the skin.
