Monroe, Wisconsin- Prolibra improved body composition by significantly reducing body fat while retaining lean muscle mass according to a human clinical study recently published in the open access journal Nutrition & Metabolism. Prolibra is a patent-pending, all natural specialized whey fraction developed by Glanbia Nutritionals as a healthy solution to weight loss.

While both groups in the diet study lost weight, subjects supplementing their diet with Prolibra lost an average 6.1% of their body fat mass versus an average 3.5% for the control. A reduction of 5% of body fat mass has been shown to reduce the risk of obesity-related disease, so the results have practical significance. “Prolibra subjects lost significantly more body fat compared to control subjects in the completer (2.81 kg vs. 1.62 kg P=0.03) and responder (3.63kg vs 2.11kg P=0.01) analysis,” according to the study. Prolibra subjects also lost significantly less lean muscle mass than the control in the responder analysis (1.07kg vs. 2.41kg P=0.02). Retaining lean muscle translates into increased body strength, basal metabolic rate and bone strength.

In addition, study administrators observed fat-directed weight loss of 79% (fat loss/(lean loss + fat loss) versus 51% for the control.

“Based on the results of this human clinical trial and an earlier trial, Prolibra is fully backed by substantiated claims which can be used to support finished products containing Prolibra,” said Sharon Rokosh, business development manager at Glanbia Nutritionals in Monroe, Wisconsin. “The concept of targeting fat as a key to healthy weight loss has resonated well in focus groups we’ve conducted, and Prolibra’s ability to specifically target fat while retaining lean is now further substantiated with this research.”

The study was conducted at the Minnesota Applied Research Center in Edina Minnesota and the data was analyzed at the Geriatric Research Education and Clinical Center of the Veteran’s Administration Medical Center in Minneapolis. The randomized, double-blind, parallel-arm 12 week study of 106 adults with body mass index of 30-42 kg/m2 was based on a caloric intake reduction of 500 calories per day and consumption of either a Prolibra or isocaloric ready-to-mix beverage 20 minutes before breakfast and 20 minutes before dinner.
