Creatine plays a vital role in sports nutrition as it helps to fuel high-intensity exercise. It is a naturally occurring compound found in small amounts in certain foods and is also synthesized in the body. By enhancing the availability of phosphocreatine in the muscles, creatine supplementation can improve ATP production, enabling athletes to perform better in short bursts of intense activity, such as sprinting or weightlifting. Moreover, creatine may assist in muscle recovery after workouts, enhance muscle mass, and support overall physical performance, making it a popular choice among athletes.
