Creatine is a naturally occurring compound that is primarily found in muscle cells. It helps supply energy to muscles during high-intensity exercise or heavy lifting. Creatine is also produced in the body from amino acids, mainly in the liver, kidneys, and pancreas, and it can be obtained from dietary sources, particularly meat and fish. In sports and fitness contexts, creatine is often used as a dietary supplement to enhance athletic performance, increase muscle mass, and improve recovery.
