Extensive research has established glutathione peroxidase 4 (GPX4) as a critical regulator in the pathogenesis of multiple pathological conditions, including osteoarthritis 35 ,cancers 47 , and liver disease 48
Tennis elbow, rotator cuff issues, Achilles tendinopathy, and knee ligament injuries show particularly good response rates
The meta-analysis found that prolonged CP supplementation alongside resistance or concurrent training produced statistically significant improvements in fat-free mass, maximal strength, and tendon morphological adaptations.7 Most trials administered 15 grams of specific collagen peptides (SCP) daily, though emerging 2024 data suggests 30 grams may further enhance collagen synthesis in resistance-trained subjects
