Dr. John Cannell

John Jacob Cannell, M.D. (born June 21, 1948, Washington, D.C.) is an American doctor. 

Education and career

Dr. Cannell obtained his medical degree from the University of North Carolina, Chapel Hill. Over the years, he has practiced psychiatry and worked as a general practitioner. His interest in Vitamin D began during his time as a psychiatrist in a maximum-security hospital, where he made a significant discovery.

While working at the Atascadero State Hospital in California, Dr. Cannell noticed that patients with lower levels of vitamin D were more susceptible to respiratory infections. This observation led him to research the relationship between vitamin D and the immune system, eventually concluding that vitamin D deficiency is a widespread health issue.

Dr. Cannell believes in the importance of evidence-based medicine and promoting healthy lifestyles. He emphasizes the need for a holistic approach to health, considering factors such as nutrition, exercise, and mental well-being. His work with vitamin D exemplifies this philosophy, as he recognizes the critical role this nutrient plays in various aspects of human health. He was the founder of the globally recognized Vitamin D Council.
