This critique finds methodological issues in a meta-analysis claiming collagen is superior to whey in improving strength and fat-free mass.

This critique aims to address and question the claims of collagen superiority over whey protein based on a recent network meta-analysis.
Critique of the network meta-analysis methodology and ranking interpretations.
Evaluation of the evidence base for collagen compared to whey protein, focusing on study size and effect sizes.
Assessment of transitivity and clinical exchangeability among listed protein trials.
Examination of measurement methods for fat-free mass (FFM) using bioelectrical impedance analysis (BIA).
Review of the search strategy and exclusion of relevant studies in the meta-analysis.
The meta-analysis claims collagen is superior to whey, but statistical significance is lacking for strength outcomes.
Collagen's evidence base is weak, with only a few small studies influencing the findings.
Measurement methods for FFM may conflate hydration effects with actual muscle gain, misrepresenting results.
Relevant studies comparing collagen and whey were omitted, raising concerns about selection bias.
