Published in British Journal of Nutrition
Methodology
Randomized, double-blind, placebo-controlled trial: 53 sarcopenic older men performed 12 weeks of resistance training with 15 g/day collagen peptides or placebo.
Key Findings
The collagen group gained significantly more fat-free mass and muscle strength and lost more fat mass than placebo.
Conclusions
Collagen peptides combined with resistance training improved body composition and strength in sarcopenic older men.
Limitations
Small, male-only sample; manufacturer-funded; protein dose not matched to placebo in a fully isonitrogenous way.
Supplements Studied
Collagen peptides improved fat-free mass and muscle strength versus placebo
Outcomes Measured
Collagen peptides improved fat-free mass and muscle strength versus placebo, supporting connective tissue adaptation to loading
