Subcommittee chair Senator Clair McCaskill talked about the "Oz Effect." After Oz endorses unproven products such as green coffee extract and raspberry ketone, businesses often use his own quotes to help them sell products that are ineffective at best and dangerous at worst. The weight-loss supplement industry is notorious for false advertising and tainted products. Yet it's no wonder they quote Dr. Oz. He's well known and liked, and his endorsements already sound like copy lifted from a dubious infomercial, although they never mention brands. "You may think magic is make-believe, but this little bean has scientists saying they found the magic weight-loss for every body type," he once said about green coffee extract.
