Yes, Creatine is a widely researched and popular dietary supplement that has been shown to increase muscle size and muscle mass when combined with resistance training. It is one of the most effective and well-studied supplements for improving athletic performance and promoting muscle growth.
Creatine works by increasing the body's phosphocreatine stores, which helps to replenish ATP (adenosine triphosphate) more rapidly during high-intensity exercise. This can lead to improved exercise performance, allowing individuals to lift heavier weights or perform more repetitions during resistance training workouts.
