Help muscle cells produce more energy

Creatine supplements enhance the phosphocreatine reserves in your muscles. Phosphocreatine promotes the synthesis of adenosine triphosphate (ATP), the main chemical that your cells require for energy and other basic biological activities. ATP is broken down to provide energy during activity. Because you utilize ATP quicker than you create it, your capacity to consistently function at maximal intensity is limited.

Creatine supplements boost your phosphocreatine storage, allowing you to generate more ATP energy to power your muscles during high-intensity activity. This is the key mechanism through which creatine improves performance.
