Vitamins and Minerals
You don’t need a lot of them, but you can’t live without them. Vitamins are a group of 13 substances the body must have. You generally get vitamins and minerals from the food you eat.
Vitamin A, also called retinol, is necessary for healthy vision. It also helps create strong bones and teeth, and a strong immune system. Vitamin D is made in the body when sunlight hits the skin. The vitamin is also found in certain foods, and it is added to others, such as milk. Vitamin D helps the body absorb the mineral calcium.
