Creatine For Muscle Building: What The Evidence Actually Says

What creatine actually does

Increases the availability of a molecule (ATP) your muscles use for quick, high-intensity effort — meaning slightly more strength and power output per set, which over time contributes to greater training volume and muscle growth.

The safety record

Creatine monohydrate is among the most extensively studied supplements available, with a long track record of safety in healthy individuals at standard doses, despite persistent myths about kidney damage that aren't supported by the research in healthy people.

How to actually take it

A simple daily dose of around 3-5 grams, taken consistently (timing relative to workouts doesn't appear to matter much), is the standard, well-supported approach — no need for complicated loading or cycling protocols.

What it won't do

It's not a substitute for training or eating properly — it's a modest performance enhancer that works alongside a solid training and nutrition foundation, not instead of one.
