The Claim
Serum procollagen type 1 N-terminal peptide (P1NP) increases by approximately 10% after 3 weeks of eccentric resistance training in fit young males, and this increase is not enhanced by collagen peptide supplementation.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
After three weeks of eccentric resistance training, levels of a specific bone and tendon marker called P1NP rise by about 10% in healthy young men. Taking collagen peptide supplements does not make this increase any larger.
See the scientific wording
Serum procollagen type 1 N-terminal peptide (P1NP) increases by approximately 10% after 3 weeks of eccentric resistance training in fit young males, but this increase is not enhanced by collagen peptide supplementation.
What the research says
1 studyThe study found that doing eccentric exercises made a specific protein marker in the blood go up by 10%, just like the claim said. Adding collagen supplements didn’t make it go up any more than just doing the exercises alone.
