Vitamins
Class Overview
Vitamins are essential nutrients that your body needs in small amounts to stay healthy. They are found naturally in foods, but your body cannot make them, so you must get them from your diet. Vitamin supplements help fill gaps when your diet is lacking or treat specific vitamin deficiencies.
Mechanism of Action
Vitamins work in different ways depending on the type. Some act as cofactors for enzymes, helping chemical reactions happen in your body. Others, like vitamin D, act like hormones to regulate calcium and bone health. They support growth, development, and overall body function.
