The Food and Drug Administration has authority over a $33 billion business in dietary supplements for weight loss and work-outs sold in hundreds of vitamin shops across the nation. Do regulators hired from the industry itself have conflicts of interest? Some dietary supplements approved by the FDA have been withdrawn from the shelves in Canada. There, authorities say they pose "a serious health risk" because they contain a chemical much like amphetamine, the powerful stimulant. But the FDA says that "does not identify a specific safety concern at this time."
The FDA's approval of JetFuel Superburn and other supplements has raised questions from researchers and from Anahad O’Connor, a consumer health reporter at the New York Times and a fitness buff.
