The Claim

Collagen peptide supplementation does not increase muscle collagen synthesis rates during recovery from eccentric exercise in young males, as measured by P1NP response and functional recovery, when compared to whey protein supplementation alone.

Source: Partly Substituting Whey for Collagen Peptide Supplementation Improves Neither Indices of Muscle Damage Nor Recovery of Functional Capacity During Eccentric Exercise Training in Fit Males.

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 after intense exercise does not lead to greater muscle repair or higher levels of a specific collagen marker compared to taking whey protein alone in young men.

See the scientific wording

Collagen peptide supplementation does not increase muscle collagen synthesis rates during recovery from eccentric exercise in young males, as evidenced by the absence of enhanced P1NP response or functional recovery compared to whey protein alone.

What the research says

1 study
  1. Study: Partly Substituting Whey for Collagen Peptide Supplementation Improves Neither Indices of Muscle Damage Nor Recovery of Functional Capacity During Eccentric Exercise Training in Fit Males.

    Scientists gave two groups of guys protein after intense leg workouts—one group got only whey protein, the other got whey plus collagen. Both groups recovered the same way, so adding collagen didn’t help them heal faster or stronger.
