Creatine is an amino acid. Amino acids are individual parts of larger protein molecules. Each amino acid has its own job and purpose. The body uses creatine to make phosphocreatine, which it stores in muscle. Phosphocreatine can then be removed from the muscles and used for energy. Research shows that creatine is a great, healthy way to build muscle mass, improve workouts, strengthen the heart, and reduce the effects of aging on the skin. Research also shows that it’s important to drink plenty of water when using creatine. That’s because creatine can cause certain dehydration-related problems. Nearly all these issues can be fixed by drinking extra water. If you’re looking to take your physical strength to the next level, try adding creatine supplements to your nutrition routine.
