Collagen Peptides May Help Ease Exercise-Induced Knee Discomfort

Knee joint discomfort can be caused by a sudden injury, an overuse injury, or by an underlying condition. According to a recent study, supplementation with collagen peptides may help ease exercise-related knee joint discomfort in young adults.

One-hundred-eighty active adults with an average age of 24 participated in the study. All had exercise-related knee joint discomfort. They received 5 grams of collagen peptides or a placebo daily for 12 weeks. The researchers assessed changes in knee joint discomfort during and after exercise at baseline and at the end of the study. They also evaluated discomfort after resting and after 20 squats.

The reseachers found that participants in the collagen peptide group saw a significantly higher reduction in exercise-induced knee discomfort compared to the placebo group. No significant differences in discomfort were seen between the groups during resting conditions and after performing 20 squats.

The study was conducted by researchers from the University of Freiburg and the University of Vienna. It was published on February 5, 2021 in the journal Nutrients.
