Dr. Paul Eck (1925-1996) was a brilliant researcher, clinician and the founder of Analytical Research Laboratories in Phoenix, Arizona, USA.

Dr. Eck stumbled upon the new assessment method of Hair Tissue Mineral Analysis in the early 1970’s and, where others saw it mainly as a way to detect toxic metals, Dr. Eck applied to this finding all of his knowledge of The Stress Theory of Disease (Hans Selye, MD), Metabolic Typing (George Watson, PhD), Autonomic Nervous System Balancing (Melvin Page, DDS), and more. From there he developed Nutritional Balancing Science, also called “The Science of Human Energy”, a new system of healing and a way of balancing the body allowing it to heal itself. Learn more.
