Not subject to scientific scrutiny by the Federal Food and Drug Administration (DFA), dozens of dietary and weight loss supplements carry claims that are unsubstantiated. According to Naharnet
the report states:
"Consumers rely on a supplement's claims to determine whether the product will provide a desired effect, such as weight loss or immune support. Supplements that make disease claims could mislead consumers into using them as replacements for prescription drugs or other treatments for medical conditions, with potentially dangerous results."
places the onus on the manufacturers of dietary supplements to ensure their labeling is truthful and their products safe. According to Find Law
Federal regulations do not require the FDA to "review supplement companies' scientific evidence for most of their products' purported health benefits before they hit the market."
Many supplements are now reported as carrying spurious health claims, a situation that has not improved since the government reported
on dietary supplements in 2001. The FDA has now agreed it should increase its surveillance of the dietary supplement market, in light of the findings that some of the supplements illegally claim to offer cures for diseases.
