Who We Are

Dr. Peter D’Adamo is a naturopathic physician and world-renowned expert in personalized nutrition. In 1996, he published the New York Times bestseller Eat Right 4 Your Type, which introduced the revolutionary idea that your blood type shapes your unique biochemical universe. His work has sold over 8 million copies worldwide, is available in over 65 languages, and continues to influence the fields of nutrigenomics and personalized medicine. Besides developing the Blood Type Diet, Dr. D'Adamo has over three decades experience in natural products development. He is a distinguished professor emeritus in clinical medicine at the University of Bridgeport, and the recipient of the 2023 Leadership Award from the Integrative Healthcare Symposium.

"I am afraid that Peter's merits are not estimated enough in the scientific world. Therefore it seems to me necessary, not only to promote his concept here in Europe, but also to tell him that I acknowledge him as one of the most creative scientists in the Western world."
--- Gerhard Uhlenbruck, PhD, MD Lectinologist, Institute of Immunobiology, University of Cologne
