Creatine is an organic compound with the nominal formula
(H2N)(HN)CN(CH3)CH2CO2H. It exists in various tautomers in solutions
(among which are neutral form and various zwitterionic forms).
Creatine is a natural source of energy that helps your
skeletal muscles flex (contract). It helps create a steady supply of
energy in your muscles so they can keep working, especially while you're
exercising.
Many amateur and professional athletes take creatine supplements to aid
their workout routines and improve their recovery.
Creatine creates “quick burst” energy and increased strength, which improves your performance without affecting your ability to
exercise for longer periods (aerobic endurance).
