Creatine is a well-researched compound known for its role in muscle energy metabolism, particularly in the context of sports performance and muscle strength. The "Structural System" of the body typically refers to the musculoskeletal system, which consists of bones, muscles, connective tissues, and cartilage. The primary scientific evidence supporting creatine use relates to its ability to enhance muscular strength, increase lean muscle mass, and improve performance in high-intensity, short-duration activities. These effects are consistently demonstrated in numerous randomized controlled trials and meta-analyses.

Creatine supplementation increases phosphocreatine stores in muscle tissue, allowing for faster regeneration of ATP, the primary energy currency during intense muscular activity. This directly contributes to improved muscle performance and aids in muscle recovery and growth (hypertrophy) following resistance training. While creatine does not impact bone density directly, improved muscle strength and mass can indirectly support the structural system by enhancing stability, reducing the risk of falls, and potentially exerting beneficial mechanical forces on bone tissue.

There is less evidence for creatine's direct effects on other components of the structural system such as bone or cartilage. However, some emerging studies suggest creatine may help mitigate muscle wasting in older adults (sarcopenia), further supporting its role in maintaining musculoskeletal health. Overall, the use of creatine to support the structural (musculoskeletal) system is strongly supported by scientific evidence, particularly regarding muscle function.
