Creatine is not a protein powder, but a dietary supplement commonly used for enhancing athletic performance and increasing muscle mass. It is a nitrogenous organic acid that occurs naturally in the body, primarily in the muscle tissue.
Creatine works by increasing the production of adenosine triphosphate (ATP) in the body, which is the main source of energy for muscle contractions. Supplementing with creatine can increase the amount of ATP available for the muscles, allowing for more intense and longer workouts.
While creatine is often sold in powder form, it is not a protein powder. Protein powders are made from various sources of protein and are used to supplement a person's daily protein intake, while creatine is specifically used to enhance athletic performance.
