You are visiting the official website of the International Society for Orthomolecular Medicine (ISOM).

This site is directed towards health professionals/scientists, interested in orthomolecular medicine.

The ISOM is the only international professional medical organization, which maintains and protects the tenets of the founders of orthomolecular medicine, dr. Abram Hoffer and two-time Nobel price Laureate prof. dr. Linus Pauling.

Dr. Abram Hoffer was the first physician who treated schizophrenic patients with high (optimum) doses of niacin and vitamin C in 1954.

Dr. Linus Pauling was the first who described the theory behind orthomolecular medicine in Science in 1968.

Dr. Pauling: 'Dr. Hoffer has made an important contribution to the health of human beings and the decrease of their suffering through the study of the effects of large doses of vitamin C and other nutrients … I believe that a really great improvement in health can be achieved through the ingestion of the optimum amounts of vitamins and nutrients.'
