HEART OF THIS MEDICAL RESEARCH: Fix The Problems By Restoring Normal Function, something drugs cannot do

The Relative Nutritional Deficiency Paper, full text

This research, which started in 1997, has led to the publication of its discoveries in over 20 peer-reviewed scientific papers in the medical journals since 2009.

In 2014 we published the following definition of drug and nutrient. While these definitions may seem simple, the implications are profound. They are the foundation of our research philosophy: restoring normal function to the system.

PUBLISHED DEFINITION: A nutrient is any substance that facilitates normal system function. A drug is any substance that induces abnormal system function. A nutrient may become a drug. A drug may not become a nutrient (carbidopa death paper paper 1, carbidopa dyskinesia paper paper 2).


Under this definition, the way most nutrients are given converts them to drugs when one or more systems in the body begin to function abnormally.

Example: 5-hydroxytryptophan (5-HTP) is a nutrient. When it is administered as a single agent, dopamine depletion may occur. If it induces dopamine depletion, then 5-HTP no longer functions as a nutrient; it is a drug. L-dopa may be administered as a nutrient. When it is administered as a single agent, serotonin depletion may occur. If it induces serotonin depletion, then L-dopa no longer functions as a nutrient; it is a drug. (paper 1)

When nutrients are given properly there are no side effects. Using a drug or turning a nutrient into a drug is associated with side effects, abnormal system function, and suboptimal treatment results.

We are the medical doctors who published these findings; let us help you analyze your patients’ medical problems and work to restore normal system function, something that drugs cannot do.
