Potentially Dangerous Dietary Supplements

Several dietary supplements have been identified as more likely to cause harm than others. The FDA, the National Center on Complementary and Alternative Medicine, the consumer protection and education magazine Consumer Reports, and other organizations have published warnings for consumers (Table 3.5). Review of the scientific literature and actual adverse event reports revealed that these supplements may cause organ damage, cancer, or other adverse effects; are currently the subject of an FDA warning; or pose significant theoretical risks.
