The Claim

Collagen peptide supplementation during resistance training enhances the upregulation of molecular pathways related to muscle contraction, protein folding, and stress response (including MAPK, Akt/mTOR, and HSF1) in skeletal muscle, while placebo supplementation during resistance training activates only general metabolic pathways, demonstrating a targeted molecular adaptation.

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.

How it works
1 study reviewed
In plain English

Taking collagen peptides while doing strength training leads to specific changes in muscle cells that support muscle function and repair, whereas taking a placebo during the same training only triggers general metabolic changes.

See the scientific wording

Collagen peptide supplementation during resistance training enhances upregulation of pathways related to muscle contraction, protein folding, and stress response (e.g., MAPK, Akt/mTOR, HSF1) in skeletal muscle, whereas placebo only activates general metabolic pathways, indicating a targeted molecular adaptation.

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

    Taking collagen peptides after workouts helped muscles build more of the proteins needed for strength and movement, while just working out without them only boosted general body functions. This means collagen peptides help muscles adapt in a more specific and powerful way.
