To the Editor.—The practice of physician involvement in a "multilevel marketing" arrangement of promoting and selling nutritional supplement products directly to patients came to our attention when some patients in our health care system complained of their "high-priced" vitamin therapy. We found that several of our physicians were recommending and selling a patented formulation of fiber, vitamins, amino acids, minerals, trace elements, and coenzymes known as "Bio-C," "Cardio-Basics,"and "Bios Life 2 Natural" manufactured by Rexall Showcase International (RSI), Boca Raton, Fla.
