Clinical and experimental rheumatology (2025) · Meta analysis · n=870
The meta-analysis revealed an overall significant improvement of both function [MD, -6.46 (95% CI -9.52, -3.40); I2=75%; p=0.00001] and pain scores [MD, -13.63 (95% CI -20.67, -6.58); I2=88%; p=0.00001], favouring collagen supplementation.
Impact of Collagen Peptide Supplementation in Combination with Long-Term Physical Training on Strength, Musculotendinous Remodeling, Functional Recovery, and Body Composition in Healthy Adults: A Systematic Review with Meta-analysis
Sports medicine (Auckland, N.Z.) (2024) · Meta analysis · n=768
This systematic review and meta-analysis represents the first comprehensive investigation into the effects of long-term CP supplementation combined with regular physical training on various aspects of musculoskeletal health in adults.
Large meta-analyses show minimal to nonexistent benefits. Effects appear modest at best, with significant study heterogeneity. Combination with glucosamine may be more effective than chondroitin alone.
Meta-analysis of 23 RCTs (n=1474) found collagen significantly improved skin hydration, elasticity, and wrinkles overall, but high-quality and non-industry-funded studies showed no significant effect. Hydrolyzed collagen peptides preferred for bioavailability.
