Quick Summary

In this meta-analysis of randomized controlled trials, most of which included an exercise intervention, supplemental collagen increased muscle mass, strength, and tendon cross-sectional area, compared to a placebo.

What was studied?

The effects of supplemental collagen in the context of an exercise intervention or exercise recovery.

The following outcomes were assessed:

  • Whole-body fat-free mass
  • Muscle mass, typically measured as the cross-sectional area or muscle thickness of the quadriceps
  • Tendon cross-sectional area of the achilles tendon or patellar tendon
  • Tendon stiffness of the achilles tendon or patellar tendon
  • Upper-body or lower-body strength, typically measured as 1-repetition maximum or maximal voluntary isometric contraction
  • Exercise recovery, measured as strength or countermovement jump height up to 48 hours after performing muscle-damaging exercise, as well as perceived muscle soreness
