The history of orthomolecular psychiatry
Pauling, Pfeiffer, Walsh, Hoffer — who is behind this method
Five researchers who connected brain biochemistry to targeted nutritional treatment. From Nobel laureate Linus Pauling to William Walsh and his database of 30,000 patients.
Orthomolecular psychiatry is not an internet trend. Nor is it "alternative medicine" in the sense of lacking data. It is a line of clinical research that began in the 1960s and, over decades, gathered data from tens of thousands of patients. Here is a brief overview of the people whose work forms the foundation of this entire field.

Linus Pauling — the man who gave it its name
Two-time Nobel laureate (Chemistry 1954, Peace 1962). In 1968 he published an article titled "Orthomolecular Psychiatry" in the journal Science, where he coined the term orthomolecular.
The core idea: the brain is an organ that functions within a chemical environment. Optimizing that environment using naturally occurring substances (vitamins, minerals, amino acids) can be an important part of treating mental illness.
Abram Hoffer — niacin and schizophrenia
A Canadian psychiatrist who, together with Humphry Osmond, conducted the first double-blind clinical trials using high-dose niacin (biotype 3) for schizophrenia. He treated more than 10,000 patients and published dozens of books.
Hoffer's work inspired part of today's orthomolecular practice around support for addiction — though this is not standard treatment.
Carl Pfeiffer — the Brain Bio Center
An American physician and pharmacologist. In the 1970s he founded the Brain Bio Center in Princeton and examined thousands of patients with schizophrenia, depression, anxiety, ADHD, and autism.
He described three basic biotypes — histadelia, histapenia, and pyroluria — and published the book Nutrition and Mental Illness (1987), which remains the foundational reference work in this field.
William Walsh — the largest clinical database
Originally a chemist at Argonne National Laboratory. After meeting Pfeiffer, he took over his work and built the Walsh Research Institute, with more than 30,000 patients and 3 million biochemical data points.
He split the original three biotypes into five and published the book Nutrient Power (2012). Now in his 80s, he still actively trains physicians on every continent.
The European line of pyroluria research
In Europe (mainly the Netherlands and Germany), research into pyroluria developed in parallel with the American line. European orthomolecular laboratories developed a precise test for pyrrole molecules in morning urine — today a recognized standard.
Thanks to this methodology, PsyLab is able to make the pyroluria test available to clients in Slovakia as well.
