• Most people can obtain the recommended dietary intakes of the vitamins
and minerals needed for good health by eating a variety of foods.
• Vitamin deficiency may occur in the elderly; when nutrients are limited in
one’s diet, for example, B12 deficiency among vegetarians; as a result of a
health problem; or caused by tobacco or alcohol use.
• Dietary supplements, including multivitamins, multiminerals, herbs, and
sports drinks, usually do not preserve or enhance health, boost athletic
performance, or protect against disease.
• Large doses of either single nutrient supplements or high potency vitamin and
mineral combinations may be harmful.
• Be especially wary of the risk of supplements other than vitamins, especially
herbal and botanical supplements—most are unproven to be beneficial, and
many are harmful.
• Do not self-prescribe, consult a medical professional before taking any type of
supplement other than a standard low-dose multivitamin/multimineral.
