SERIOUS about Your



100% Whole Food Supplements that are
TRUSTED by Healthcare Professionals

Doctors’ Research, Inc. is dedicated to continuing research, as well as, providing the highest quality 100% FOOD nutritional supplements to licensed healthcare professionals, in a form that is as close as possible to those naturally found in foods. It is well understood by nutrition researchers that we, as humans, should derive nutrition from food.

It is our goal at Doctors’ Research to provide the best, scientifically researched, natural food supplements which meet the needs of those who live in our “modern” society. 

Doctors’ Research products are environmentally friendly. They are natural food complexes which have been shown to be better for the internal human environment. They are supplied in recyclable glass bottles which we feel are better for the global environment (as well as the supplement’s environment).

100% FOOD nutrients, such as are
in Catalyst Complex™ are superior to Catalyn®.

Catalyn® contains six chemical vitamin additives and three processed rocks (Catalyn®, Product Bulletins, 1953) (mineral salts). A careful reading of the label shows that Catalyn® contains vitamin isolates as the primary source of each of the claimed nutrients.​

All Catalyst Complex™ nutrients are in the same chemical forms as food which makes them better absorbed, utilized and retained by the human body (Medical Hypotheses, 2000; 55(6):461-469).
