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.

Effects of 12 Weeks of Hypertrophy Resistance Exercise Training Combined with Collagen Peptide Supplementation on the Skeletal Muscle Proteome in Recreationally Active Men

Randomized Controlled Trial

Human

2019 May 14

This 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.

Similar Assertions

Taking collagen peptides while doing strength training does not lead to greater increases in maximum strength in young men compared to strength training alone, even though it may increase muscle mass and protein markers.

Strength training alone helps middle-aged men build muscle and lose fat, but adding this collagen supplement makes those improvements even better.

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.
