    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
