Vitamin A is a fat-soluble vitamin that is stored in the liver. It is found in animal products such as meat, fish, poultry, and dairy foods.
It is key for good vision, a healthy immune system, and cell growth. There are two types of vitamin A. This entry is primarily about the active form of vitamin A — retinoids — that comes from animal products. Beta-carotene is among the second type of vitamin A, which comes from plants.
Vitamin A helps form and maintain healthy teeth, skeletal and soft tissue, mucus membranes, and skin. It is also known as retinol because it produces the pigments in the retina of the eye.
