The one that actually works
Creatine
The best-evidenced supplement in sport, and it is not close.
Hundreds of trials, forty years of them, and a conclusion that has not meaningfully shifted. Five grams a day, every day. Loading phases are optional and mostly a way of selling you more powder faster.
| Amount | Nutrient | Why |
|---|---|---|
| 5 g | Creatine monohydrate | Increases physical performance in successive bursts of short-term, high-intensity exercise. |
| — | Not HCl, not ethyl ester | Monohydrate is the form the research used. The alternatives cost more and have less behind them. |
What to avoid
Paying extra for a 'newer' form. Creapure monohydrate is the reference standard and everything else is marketing on top of it.
Worth knowing
It takes two to four weeks of daily use to saturate. Timing around your session matters far less than not missing days.
