Study Shows Weight Loss Supplements No Better than Placebo

July 13, 2010 No Comments by Scott Isaacs MD

In a placebo-controlled, randomized study by Dr. Thomas Ellrott, 9 commonly used weight loss supplements were found to be no better than placebo.  The supplements tested included cabbage powder, sodium-alginate, fiber, bean concentrate (phaseolamine), L-carnitine, konjac extract, chitosan, and guarana-seed powder.  The trial, conducted in Germany showed equal weight loss, about 4-5 pounds in 2 months in subjects who took either a weight loss supplement or placebo, with no difference between the groups.  The study very well done, and shows that the supplements are no better than sugar pills. The only thing [patients] will lose is their money,” commented Judith S. Stern, Sc.D., a professor of nutrition at the University of California, Davis.
