Orthomolecular is a term that comes from ortho, which is Greek for "correct" or "right," and "molecule," which is the simplest structure that displays the characteristics of a compound.
So it literally means the "right molecule."
Two-time Nobel Prize winner, and molecular biologist, Linus Pauling, Ph.D.,coined the term "Orthomolecular" in his 1968 article
"Orthomolecular Psychiatry" in the journal "Science."
Orthomolecular medicine describes the practice of preventing and treating disease by providing the body with optimal amounts of substances which are natural to the body.
