Doctors' Research 100% Whole Food Supplements

Doctors' Research, Inc. is dedicated to providing the highest quality nutritional supplements, 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).

Who heads up the research team at Doctors' Research?
The research group at Doctors' Research is directed by Robert Thiel, N.H.D. who also holds a Ph.D. in nutrition science. He is licensed as a naturopath by the State of North Carolina, registered as a naturopath by the District of Columbia, and is licensed as a naturopathic physician within Idaho. He maintains a natural health clinic in Arroyo Grande, California.

DR. THIEL conducts lectures for health care professionals on a variety of natural health topics; he has also written four books for health care professionals. He has conducted, and had published, many scientific health studies. Thiel received the Leadership Award from the Orthomolecular Health Medicine Society. Thiel has been named Research Scientist of the Year, Physician of the Year, and Disability Researcher of the Year by the largest American naturopathic association. Doc. Thiel has had the only comprehensive paper published in a medical peer-reviewed journal (Medical Hypotheses) on the advantages of natural food vitamins over synthetic 'nutrients'.

Why are Doctors' Research Food nutrients better than isolated USP nutrients?
Human beings should get their nutrition from foods. "The body is designed to handle foods" [1]. It is important to realize "that in nature vitamins are never isolated. They are always present in the form of vitamin-complexes" [2-5]. Vitamins are natural complexes which produce a variety of actions in the body whereas some isolated USP vitamins are analogues of vitamins which appear to have at least some of these activities [5]. Food nutrients are complexed just as nutrients found in all foods, because they are food. USP vitamins are synthesized (according to strict federal standards), standardized chemical isolates (as listed in the United States Pharmacopoeia or the USAN and USP Dictionary of Drug Names) [6]; they are not food.

It is well known among nutrition researchers that most essential minerals are not well absorbed (some are less than 1%) [7]. "Bioavailability of orally administered vitamins, minerals, and trace elements is subject to a complex set of influences...In nutrition science the term 'bioavailability' encompasses the sum of impacts that may reduce or foster the metabolic utilization of a nutrient" [8]. Studies show that natural food complex nutrients are better than isolated USP vitamins or inorganic mineral salts or mineral chelates [e.g. 9-25].

Numerous university studies have concluded that supplements containing food nutrients are better than USP isolates. Food nutrients are better because they contain important enzymes, peptides, and phytonutrients CRITICAL to the UTILIZATION of vitamins and minerals which are not present in isolated USP nutrients. Published research has concluded that food vitamins are superior synthetic/USP vitamins.
