Creatine Monohydrate

The Strength Reserve

Creatine monohydrate · C₄H₉N₃O₂·H₂O

A muscle fuel reserve that helps short bursts of hard work repeat.

Creatine is a compound the body makes from amino acids and stores in muscle, where it helps regenerate the energy used in short, intense effort. It is among the most-studied supplements in existence, with strong evidence for strength and muscle, and the long-standing fear that it harms the kidneys is not supported in healthy people.
