Creatine works by accelerating how fast your cells regenerate ATP – the molecule that powers essentially every biological process. When cells run through their ATP during high-demand work – whether that’s a heavy set or an hour of focused thinking – creatine donates a phosphate group that rebuilds ATP faster than the baseline pathway can. The result is more output before fatigue, and faster recovery between efforts.

The muscle performance case.

Five hundred-plus human clinical trials make creatine the most-studied supplement in sports nutrition. The findings are consistent: creatine supplementation increases strength, power output, and lean muscle mass – particularly during high-intensity, short-duration efforts. The mechanism is straightforward: more available ATP means more work before the energy system gives out.

The brain case – less talked about, equally supported.

Your brain accounts for roughly 20% of your body’s energy use and runs the same ATP-creatine system your muscles do. Research shows creatine supplementation improves working memory, reasoning, and mental fatigue – particularly under sleep deprivation or high cognitive load. Vegetarians and vegans, who get no dietary creatine from meat, show the largest cognitive effects from supplementation.

Micronized – and why it matters.

Standard creatine monohydrate is a coarse powder that settles in the glass and can be rough on the stomach. Micronization reduces particle size mechanically – same molecule, better suspension, easier digestion. No loading protocol required; 5g daily builds tissue saturation over 3–4 weeks without the bloating that loading phases sometimes cause.
