Who needs supplements?
If you're generally healthy and eat a wide variety of foods, including fruits, vegetables, whole grains, legumes, low-fat dairy products, lean meats and fish, you likely don't need supplements.However, the dietary guidelines recommend supplements — or fortified foods — in the following situations:
- Women who may become pregnant should get 400 micrograms a day of folic acid from fortified foods or supplements, in addition to eating foods that naturally contain folate.
- Women who are pregnant should take a prenatal vitamin that includes iron or a separate iron supplement.
- Adults age 50 or older should eat foods fortified with vitamin B-12, such as fortified cereals, or take a multivitamin that contains B-12 or a separate B-12 supplement.
Dietary supplements also may be appropriate if you:
- Don't eat well or consume less than 1,600 calories a day
- Are a vegan or a vegetarian who eats a limited variety of foods
- Are a woman who experiences heavy bleeding during your menstrual period
- Have a medical condition that affects how your body absorbs or uses nutrients, such as chronic diarrhea, food allergies, food intolerance or a disease of the liver, gallbladder, intestines or pancreas
- Have had surgery on your digestive tract and are not able to digest and absorb nutrients properly.
