Summary

This study tests whether a daily 40 mg dose of Collavant n2 can reduce knee discomfort in healthy, active men aged 40-65 who run regularly. Eighty amateur male runners with exercise-induced knee pain will take either the supplement or a placebo for a period, and their pain levels will be measured before and after running. The goal is to see if this supplement helps ease joint pain caused by physical activity.
