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.
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.
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.
See the scientific wording
Collagen peptide supplementation during 12 weeks of hypertrophy resistance training in young men leads to a 5-fold increase in upregulated muscle proteins associated with contractile fiber metabolism compared to placebo, including myosin, actin-binding, and Z-disk proteins, suggesting enhanced structural adaptation of the muscle sarcomere.
What the research says
1 studyPeople 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.
