What distinguishes a dietary supplement from a drug?


According to the Dietary Supplement Health and Education Act (DSHEA) of 1994, dietary supplements are products taken by mouth and intended to supplement the diet. Vitamins, minerals, herbs, amino acids, enzymes, and organ tissues are examples of ingredients in dietary supplements. Dietary supplements are classified under "foods" and do not need Food and Drug Administration (FDA) approval. Drugs are substances not classified as food and designed to affect body structure or function. They are used for diagnosis, cure, mitigation, treatment, or prevention of disease. Drug manufacturers must prove that their drugs are safe and effective for their intended use before gaining FDA approval.

Natural treatment for conditions like constipation may be effective. But because these substances are unregulated, it is always a good idea to educate yourself about the products and to use common sense when taking them. This is even more true if you are pregnant or taking a medicine that may be affected by supplements.
