Beginning around the age of 40, we humans tend to experience distressing changes in our body composition: more fat and less lean.  Of particular concern is age-related loss of skeletal muscle, which can lead to all kinds of problems as we get older.  So, while many of us would like to lose some weight, we need to focus on losing fat while retaining muscle, particularly as we get older.

Nutritionists have been pondering how to best achieve this goal for many years. Various approaches typically with increased protein intake have received mixed results, particularly for older subjects.  Until now. 

In a 13-week “gold standard” double-blind, placebo-controlled human clinical trial of 60 overweight subjects ranging in age from 57-70 years, subjects who consumed a reduced calorie diet and 20.7 g of a leucine-rich whey protein (2.8 g leucine) daily, as well as another serving three times/week after resistance training, lost weight and were completely protected against loss of muscle mass. The product also provided 500 mg calcium, 800 IU of vitamin D3 and additional vitamins and minerals.1  In an editorial published in the same issue of the American Journal of Clinical Nutrition, the study was deemed “remarkable” by experts from the Center for Human Nutrition at Washington University’s School of Medicine.2

As usual, Mannatech has been way ahead of the pack in understanding the importance of leucine-rich whey protein in protecting against muscle loss while on a weight loss regimen. 

We launched a high quality, leucine-rich whey protein supplement with advanced peptide technology— OsoLean® powder— seven years ago.  This product is backed by two human clinical trials, one a “gold standard” double-blind, placebo-controlled trial. 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.* 3, 4
