Colostrum, the early milk produced by mammals after giving birth, is rich in bioactive compounds such as immunoglobulins, growth factors, and amino acids. Scientific studies have investigated its role in supporting the muscles body system, particularly in the context of athletic performance and recovery. Several randomized controlled trials and systematic reviews indicate that bovine colostrum supplementation can modestly enhance lean body mass, support muscle recovery, and improve exercise performance, especially in physically active individuals and athletes. The proposed mechanisms include the presence of growth factors like IGF-1 (insulin-like growth factor 1), which may stimulate muscle protein synthesis and promote tissue repair. However, while some studies show statistically significant benefits—such as reduced muscle damage markers (e.g., creatine kinase) and improved recovery times—other studies report minimal or no effects, especially in non-athletic or elderly populations. The quality and standardization of colostrum supplements, as well as variations in study design, contribute to inconsistent findings. Overall, current scientific evidence supports the use of colostrum for muscle support primarily in athletic contexts, but more large-scale, high-quality trials are needed to confirm these effects and clarify mechanisms. Thus, the evidence is moderate but not conclusive.
