Older men with muscle loss who do strength training and take collagen supplements gain more muscle mass (4.2 kg) than those taking a placebo (2.9 kg).
Scientific Claim
In elderly men with sarcopenia, 12 weeks of resistance training combined with 15g/day collagen peptide supplementation increases fat-free mass by 4.2 kilograms, which is significantly greater than the 2.9 kilogram increase observed with placebo supplementation.
