People with knee pain took collagen pills daily for 12 weeks, and their pain during movement got noticeably better compared to those who took a fake pill.
Technical explanation
This study directly tests oral supplementation of specific collagen peptides (5 g/day) in young adults with knee joint discomfort and measures activity-related pain reduction using VAS, finding statistically significant improvement — matching the assertion exactly.
Young, active people with knee pain took collagen supplements for 12 weeks — their pain during exercise dropped significantly, proving collagen helps with joint discomfort after workouts.
Technical explanation
This randomized trial confirms that bioactive collagen peptides (same as Paper 1) significantly reduce activity-related knee pain in young active adults, directly supporting the assertion with identical intervention and outcome measures.
