A double-blind, placebo-controlled, randomised, clinical study on the effectiveness of collagen peptide on osteoarthritis.

Oral supplementation with collagen peptides derived from pork skin and bovine bone significantly reduced pain and improved joint function and quality of life scores in knee osteoarthritis patients over 13 weeks compared to placebo.

A double-blind, placebo-controlled, randomized clinical trial was conducted where patients with knee osteoarthritis received either collagen peptides from pork skin or bovine bone, or placebo, for 13 weeks. Outcomes were measured using WOMAC, VAS, and quality of life scores.

This study supports collagen peptides as a safe, nutritional supplement option to manage osteoarthritis symptoms and improve joint health, potentially reducing reliance on pharmaceutical pain treatments.

The study does not specify sample size or long-term effects beyond 13 weeks, and the exact strength of evidence is not detailed, limiting generalizability.
