Functional medicine (FM) is a form of alternative medicine that encompasses a number of unproven and disproven methods and treatments.[1][2][3] It has been described as pseudoscience,[4]quackery,[5] and at its essence a rebranding of complementary and alternative medicine.[5] In the United States, FM practices have been ruled ineligible for course credits by the American Academy of Family Physicians because of concerns they may be harmful.[6][7]
Functional medicine was created by Jeffrey Bland,[8] who founded The Institute for Functional Medicine (IFM) in the early 1990s as part of one of his companies, HealthComm.[9] IFM, which promotes functional medicine, became a registered non-profit in 2001.[10]Mark Hyman became an IFM board member and prominent promoter.[8][10]
