Vitamins & Supplements

The Dietary Supplement Health and Education Act (DSHEA) of 1994 defines a dietary supplement as a product taken by mouth that contains a “dietary ingredient” intended to supplement the diet. Dietary supplements contain one or more of the following: vitamins, minerals, herbs or other botanicals, amino acids, and substances such as enzymes, organ tissues, glandular products, or metabolites. They are available in a variety of forms including capsules, tablets, gelcaps, powders, softgels, liquids, and bars. The DSHEA requires that supplements be represented and labeled strictly as such—not as conventional food items. Information about the DSHEA is available on this U.S. Food and Drug Administration site: http://www.fda.gov/Food/DietarySupplements/default.htm.

Call Northwestern Memorial Hospital’s Drug Information Center at 312.926.7573 whenever you have a question about any supplement, herbal product, or drug, whether prescription or over the counter. This is a free service.
