The Claim

Collagen peptide supplementation during resistance training does not significantly enhance maximal strength gains in young men beyond those achieved with resistance training alone, despite increasing fat-free mass and muscle protein expression.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Cause and effect
1 study reviewed
In plain English

Taking collagen peptides while doing strength training does not lead to greater increases in maximum strength in young men compared to strength training alone, even though it may increase muscle mass and protein markers.

See the scientific wording

Collagen peptide supplementation during resistance training does not significantly enhance maximal strength gains in young men beyond those achieved with training alone, despite increasing fat-free mass and muscle protein expression, suggesting strength improvements may be limited by other factors.

What the research says

1 study
  1. Study: Effects of 12 Weeks of Hypertrophy Resistance Exercise Training Combined with Collagen Peptide Supplementation on the Skeletal Muscle Proteome in Recreationally Active Men

    The study found that young men who took collagen peptides while working out got stronger than those who didn’t, even though both groups got stronger. This means collagen peptides might help you get stronger, not hurt it.
