(Tampa, FL) – A team of scientists and physicians have announced the results from a series of three clinical trials that evaluated a novel portion-control dietary supplement called PREE® which was found to be safe and effective for weight loss. Three multi-center prospective studies tested PREE in 105 overweight adults. A meta-analysis of the three trials showed that daily use of PREE provided an average weight loss of 13.5 lbs over 8 weeks without unpleasant side effects.
