Products marketed as "dietary supplements" include
a diverse range of products, from traditional nutrients, such as
vitamins or minerals, to such substances as high-potency free amino
acids, botanicals, enzymes, animal extracts, and bioflavanoids that
often have no scientifically recognized role in nutrition.
Dietary supplements routinely enter the marketplace without undergoing a safety review by FDA. Published studies
on the safety of these products are extremely sparse. Because of concern about these products, the FDA now collects and evaluates existing
studies and case reports on safety problems associated with dietary
supplements and identifies dietary supplements for which serious adverse reactions have
been documented.
You can read about supplements that are on the FDA's warning list by going to Warnings and Safety Information. The FDA list is not intended to
include all hazardous ingredients in dietary supplements. |
