Mehmet Oz, America's doctor, is known for many things, but being a proponent of good science isn't one of them. Last summer, he was even dragged up to Capitol Hill and berated by senators for his bunk weight-loss prescriptions. "The scientific community is almost monolithic against you," Sen. Claire McCaskill admonished him.

Now comes more evidence of Oz's wizardry: according to the blog Retraction Watch, authors have retracted a key study that the TV doctor used to tout a green coffee bean extract for weight loss.

Such was the case for the customers of a dietary supplement company being shut down at the request of the Federal Trade Commission for making unsubstantiated health claims and signing consumers up for monthly charges without their knowledge.

The FTC announced today that it received a U.S. district court order to temporarily stop a group of marketers in Nevada and California from using allegedly deceptive tactics to sell green coffee bean extract and other dietary supplements.

According to the FTC complaint [PDF], Health Formulas, LLC, its related entities and principals in charge of the Simple Pure brand used telemarketing, the internet, print, radio and television advertisements to coax consumers into purchasing a variety of dietary supplements and other weight-loss, virility, muscle-building, or skin cream products sold under the names RKG Extreme and Pure Green Coffee Bean Plus.
