Creatine is a natural substance that plays a crucial role in energy production in the body, particularly in muscle cells. It’s synthesized in the body from the amino acids glycine, arginine, and methionine. It can also be obtained through dietary sources, particularly red meat and seafood, or via supplementation. Creatine is often used by athletes and those engaged in high-intensity workouts to enhance performance, increase muscle mass, and improve strength and endurance. It works by helping replenish adenosine triphosphate (ATP) in muscles, which is the primary molecule used for energy.
