Abstract
In this chapter, dietary supplements refer to any substance taken in addition to regular food. This includes vitamins, minerals, amino acids, herbs, enzymes, and various substances extracted from plants and animals. Some of these products are not technically dietary supplements. One person in two in North America is a regular user of dietary supplements. A great many different supplements are sold, but evidence demonstrating their efficacy is often lacking. Some supplements, especially herbal preparations, may be harmful. Supplements are often marketed in unscrupulous ways that involve giving unreliable or dishonest information. The marketing of supplements in the USA is weakly regulated. Suggestions are given on how healthcare professionals can provide solid advice to patients.
