OsoLean Powder Works!^Δ

With so many products claiming to help you be healthier or have a better body, how do you know which ones work? OsoLean powder has been clinically tested and is backed by two compelling studies:

Clinical Study

Two groups participated in this double-blind, placebo-controlled study conducted independently of Mannatech, Incorporated. Both reduced their daily intake by 500 calories; one group added OsoLean powder every day. Although both groups lost about the same amount of weight, participants who used OsoLean powder lost almost twice as much fat as those who only dieted.*

In the reduced-calorie diet, half the weight lost was fat and half was muscle. By adding OsoLean powder, almost three quarters of the weight lost was fat!*

Open-Label Study

After taking OsoLean powder for 8 weeks, participants in the Open-Label study conducted by Mannatech Incorporated lost an average of 2 ½ inches around their waists and almost 1 point on their Body Mass Index (BMI). Most participants also had more energy and better appetite control—a definite plus when you’re watching what you eat.*

The Open-Label study can be reviewed in its entirety as published in The Open Nutraceuticals Journal, 2009, 2, 36-41.
