Collagen peptides may boost body composition in middle-aged men: Study

Nutrition & Life

Data published in the International Journal of Environmental Research and Public Health ​indicated that 15 grams per day of Gelita’s BodyBalance collagen peptides for 12 weeks in combination led to statistically significant increases in fat free/ lean mass compared to placebo. The study was partly funded by Gelita GmbH. 

“To our best knowledge there are no previous studies that have focused on the effects of collagen peptides in a middle-aged, untrained male population,” ​wrote the scientists from the University of Freiburg (Germany), the Collagen Research Institute (Germany), and the University of Vienna (Austria).

“According to a previous review​ [Phillips, et al., 2009, J. Am. Coll. Nutr​.], gains in lean mass as a result of resistance training combined with protein supplementation in trained and untrained adults ranged from 0.2 to 5 kg,”​ they added. “These data are congruent with the findings of the present trial. Taking the placebo as a reference, the effect of whey protein in this trial was an additional increase in fat free mass of 0.5 kg while the administration of the applied specific collagen peptide resulted in a 1.6 kg greater gain in fat free mass.”

Study details

Led by Denise Zdzieblik from the University of Freiburg, the researchers recruited 120 untrained middle-aged men to participate in their study. The men were randomly assigned to one of three groups: Placebo, collagen peptides (15 grams per day), or whey protein isolate (15 grams per day) for 12 weeks while simultaneously undertaking a resistance training program (supervised 60-minute sessions, three times per week). Dual-energy X-ray absorptiometry (DXA) to assess changes in fat free (lean) mass and fat mass, and isometric leg strength was also measured.
