Does creatine build muscle?

Creatine is one of the most researched supplements for strength and power. It can support gains in muscle strength and lean mass when combined with resistance training, and may improve short-duration, high-intensity exercise performance.

Creatine monohydrate is the most studied form and is generally well tolerated. Typical use involves a loading phase (optional) followed by a maintenance dose of around 3–5 g per day. It works by helping replenish phosphocreatine in muscles, which supports rapid energy production during intense effort. It does not replace training or diet; it may support your efforts when used appropriately. Some people notice slight water retention initially. If you have kidney disease or other health conditions, consult a doctor before use. This is educational only; not medical advice.
