The Claim

Collagen peptide supplementation during 12 weeks of hypertrophy resistance training in young men results in a 5-fold increase in the upregulation of muscle proteins associated with contractile fiber metabolism, including myosin, actin-binding, and Z-disk proteins, compared to placebo, indicating enhanced structural adaptation of the muscle sarcomere.

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

In young men undergoing 12 weeks of muscle-building resistance training, taking collagen peptide supplements leads to a fivefold increase in the production of specific muscle proteins involved in contractile function, such as myosin and Z-disk components, compared to those taking a placebo.

  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

    People who took collagen pills after working out for 12 weeks ended up with way more muscle proteins that help muscles contract and grow, compared to those who took a fake pill. So collagen seems to help muscles get stronger and better structured.
