Mark Hyman

In April 2016, Hyman joined environmentalists and civil rights leaders in calling for federal investigations into U.S. fluoridation policy, writing that communities of color are at particular risk of adverse health impacts. In a book authored by Robert F. Kennedy Jr. (entitled Thimerosal: Let the Science Speak), Hyman wrote the preface in which he advocates for the removal of Thimerosal from vaccines.

Mark Adam Hyman is an American physician and New York Times best-selling author. He is the founder and medical director of The UltraWellness Center and was a columnist for The Huffington Post. Hyman was a regular contributor to the Katie Couric Show, until the show's cancellation in 2013. He publishes Doctor's Farmacy on the Internet, which examines many topics related to human health and welfare.

In December 2013, The Daniel Plan, a book Hyman co-authored with Pastor Rick Warren and Daniel Amen, became Number One on the New York Times bestseller list. Hyman is the author of several books on nutrition and health, such as 10 Day Detox Diet. Hyman was named the director of the Cleveland Clinical Center for Functional Medicine in September 2014.

In 2009, Hyman testified before the United States Senate Committee on Health, Education, Labor, and Pensions about integrative medical care. Hyman also participated in a Partners In Health program to bring medical care to Haiti following the 2010 Haiti earthquake.

Quackwatch lists Hyman's 2003 book Ultraprevention: The 6-Week Plan That Will Make You Healthy for Life as one of their non-recommended books due to promoting misinformation and containing unsubstantiated advice.

Hyman started his medical career as a family physician in rural Idaho and later as an emergency department physician in Massachusetts. He was the co-medical director at Canyon Ranch in Lenox, Massachusetts, from 1996 to 2004. He opened The UltraWellness Center in a small shopping mall in Lenox after leaving Canyon Ranch.
