Peptides, particularly those such as branched-chain amino acid (BCAA) peptides, collagen peptides, and creatine peptides, are increasingly used as athletic and exercise aids. Scientific evidence suggests that certain peptides can play a role in supporting muscle growth, improving recovery, and enhancing exercise performance. For example, BCAA peptides may help reduce muscle soreness and promote muscle protein synthesis when taken around exercise sessions. Collagen peptides have been studied for their potential to support joint health and reduce exercise-induced joint pain, which can indirectly aid athletic performance and recovery. Creatine peptides, a modified form of creatine, have shown similar ergogenic benefits to regular creatine supplementation, such as increased power output and muscle mass. However, while there is a growing body of scientific research supporting the use of specific peptides for athletic performance and recovery, the quality and quantity of evidence vary. Most studies focus on particular peptide types, and results may not be generalizable to all peptide supplements. Evidence tends to be stronger for BCAA and creatine peptides, while research on other peptides (e.g., collagen) is still emerging. Overall, peptides are used in sports nutrition with a moderate level of scientific validation, especially for muscle recovery and joint support, but more large-scale, high-quality clinical trials are needed to confirm their efficacy and safety across various athletic populations.
