Under its former owners - Advertising for CortiSlim originally claimed that it contributed to weight loss by blocking cortisol. The manufacturer was fined $12 million by the Federal Trade Commission in 2007 for false advertising, and no longer claims in their marketing that CortiSlim is a cortisol antagonist.
"According to the FTC, the defendants began marketing CortiSlim in August 2003, through nationally disseminated infomercials featuring Cynaumon and Talbott that aired on anumber of television channels, including Access Television, Travel Channel, and Discovery Channel. The FTC alleges that the defendants promoted cortisol control as “the answer” for anyone who wants to lose weight, especially abdominal weight. According to the FTC’s complaint, the defendants’ broadcast ads, print ads, and Web sites claimed that persistently elevated levels of cortisol, the “stress hormone,” are the underlying cause of weight gain and weight retention and also claimed that CortiSlim effectively reduces and controls cortisol levels and thereby causes substantial weight loss. The FTC alleges that the defendants claimed that CortiSlim: (1) causes weight loss of 10 to 50 pounds for virtually all users; (2) causes users to lose as much as 4 to 10 pounds per week over multiple weeks; (3) causes users to lose weight specifically from the abdomen, stomach, and thighs; (4) causes rapid and substantial weight loss; (5) causes long-term or permanent weight loss; and (6) causes weight loss. The FTC also alleges that the defendants claimed that the effectiveness of CortiSlim and its ingredients is demonstrated by over 15 years of scientific research. According to the FTC’s complaint, these claims are false or unsubstantiated."
