The Claim
In recreationally active young men, 12 weeks of hypertrophy resistance training combined with daily 15 g collagen peptide supplementation leads to a significantly greater increase in fat-free mass and a higher number of upregulated skeletal muscle proteins compared to resistance training alone with placebo.
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 who exercise recreationally, taking 15 grams of collagen peptides daily along with a 12-week strength training program results in greater gains in muscle mass and more changes in muscle proteins than strength training alone with a placebo.
See the scientific wording
In recreationally active young men, 12 weeks of hypertrophy resistance training combined with daily 15 g collagen peptide supplementation results in a significantly greater increase in fat-free mass (2.56 kg vs. 0.70 kg) and a higher number of upregulated skeletal muscle proteins (221 vs. 44) compared to resistance training alone with placebo, suggesting collagen peptides enhance muscle proteomic adaptation to training.
What the research says
1 studyThis study found that young men who took collagen pills after their workouts gained more muscle and had more muscle proteins turn on compared to those who took a fake pill—so collagen seems to help workouts build more muscle.
