MVMs cannot take the place of eating a variety of foods that are important to a healthy diet. However, few randomized clinical trials (RCTs) have been conducted because these studies need to be long enough to show effects on disease risk that go beyond simply identifying intermediate biomarkers that might suggest such risk.

Vitamins are organic molecules necessary for normal metabolism in animals, but either are not synthesized in the body or are synthesized in inadequate quantities and must be obtained from the diet. Many multivitamin products also contain minerals such as calcium, iron, magnesium, potassium, and zinc.
