Mannatech Products Review

A clinical study of OsoLean powder funded by Mannatech was published this week in the Open Nutraceuticals Journal. This preliminary, open-label, 8-week study of 112 overweight adults demonstrated that daily intake of OsoLean powder appeared to reduce appetite, support weight loss and reduce waist circumference. The study was conducted by Mannatech scientists in collaboration with researchers at the University of North Texas Health Science Center in Fort Worth, TX. In a related 12-week double-blind, placebo-controlled study published in 2008, consumption of the same peptide blend in OsoLean powder in a flavored, sweetened beverage, in conjunction with a 500-calorie reduced diet, helped to enhance fat loss and retain lean muscle mass when compared to control subjects consuming a placebo in addition to dieting.
