Dr. Mehmet Oz doesn’t pitch specific products. The celebrity doctor and Columbia University professor of surgery says clearly on his website that “Dr. Oz does not endorse any brand name or commercial supplier” and instructs viewers to check with their doctors before taking supplements. He even has an operation called Oz Watch devoted to tracking down fraudulent claims using his name or likeness, which he says has collected 35,000 complaints and resulted in 600 cease-and-desist letters.
He is also sometimes working at his own cross-purposes. At a Capitol Hill hearing Tuesday morning on deceptive advertising of weight-loss products, Oz conceded that “I’ve made [the regulators'] jobs more difficult.”
