Vitamin and mineral supplements can help address specific nutrient gaps, but choosing and using them requires care. This lesson introduces the main supplement categories, who may be more likely to need one, and how U.S. regulation affects consumers.
A diet built around fresh, minimally processed foods is generally the best source of vitamins and minerals. Still, some people may have difficulty meeting their needs through food alone. A supplement may help bridge a nutrient gap, but it does not replace a varied diet.
