Window Rock Enterprises, the former owners of the CortiSlim product line, 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, as part of the settlement, the current owner of the brand no longer claims that CortiSlim is a cortisol antagonist.[1] CortiSlim product promoters also claimed that the effectiveness[2] of CortiSlim products had been demonstrated by over 15 years of scientific research, a claim that the FTC determined to be false.[3]
