Creatine plays a significant role in muscle building by providing an immediate source of energy during high-intensity activities. It helps replenish adenosine triphosphate (ATP), the primary energy carrier in cells, allowing for enhanced performance during short bursts of intense exercise. Additionally, creatine supplementation can increase muscle mass by promoting greater strength, improved recovery, and increased workload capacity. Its ability to draw water into muscle cells can also contribute to muscle hypertrophy, making it a popular choice for athletes and bodybuilders alike.
