Functional medicine

Functional medicine (FM) is a form of alternative medicine that encompasses many unproven and disproven methods and treatments. At its essence, it is a rebranding of complementary and alternative medicine (CAM), and as such is pseudoscientific, and has been described as a form of quackery.

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.

Functional medicine was created by Jeffrey Bland, who founded The Institute for Functional Medicine (IFM) in the early 1990s as part of one of his companies, HealthComm. IFM, which promotes functional medicine, became a registered non-profit in 2001. Mark Hyman became an IFM board member and prominent promoter.
