Creatine monohydrate might be the most studied supplement in existence, with hundreds of trials across three decades. The gym benefits are settled science. The interesting part is what researchers are looking at now.
The settled part: strength and power
Creatine recycles your cells' quickest energy currency, the kind you burn in short, hard efforts. Supplementing raises muscle stores, and study after study shows modest, reliable gains in strength and power when paired with training.
The interesting part: the brain
Your brain runs on the same quick energy. Early research is exploring whether creatine supports cognition under stress, such as sleep deprivation and demanding mental work. The evidence is emerging, not settled, but it is one reason creatine keeps showing up in stacks that have nothing to do with lifting.
Dosing is boring, and that is the best thing about it
Three to five grams a day, every day. No loading phase required, no timing games, no cycling. Bigger bodies sit at the higher end of the range, smaller at the lower.
The only rule that matters is daily consistency, because muscle stores build over weeks, not hours.
The myths, quickly
The extra scale weight is water inside your muscle cells, which is where you want it. The evidence tying creatine to hair loss is thin, resting on one small study that was never replicated. And in healthy people, normal doses have not been shown to harm kidneys.
If you have existing kidney disease, that is a doctor conversation before you start. That rule has no exceptions.
General information, not medical advice. Talk to a clinician before starting a new supplement, especially if you take medication or are pregnant or nursing.
