OsoLean powder is a leucine-rich whey protein supplement with advanced peptide technology. This gold standard product is backed by two human clinical trials, one of which was a double-blind, placebo-controlled trial, the best type of trial possible. These studies, conducted on 169 overweight subjects ranging in age from 18-75 years, showed that consuming a reduced calorie diet and two servings of OsoLean powder (20 g/day leucine-rich whey protein [2.6 g leucine] and 500 mg calcium) supported fat loss while protecting against muscle loss.*1,2


† When combined with a healthy diet and regular exercise.
