Creatine benefits beyond the gym, and the dose that delivers them
Creatine benefits rest on hundreds of trials at 3 to 5 g a day: strength, lean mass, and growing evidence for cognition under sleep deprivation, with no kidney harm in healthy adults.

Key takeaways
- 3 to 5 g a day of creatine monohydrate reliably improves strength and lean mass alongside training.
- Long-term trials up to five years show no kidney or liver harm in healthy adults.
- Loading phases are optional; they only shorten the time to saturation from ~28 days to ~7.
Creatine has more human trials behind it than almost anything else in the supplement aisle, and a reputation shaped mostly by gym-floor rumour.
What it does
Creatine increases phosphocreatine stores in muscle, which regenerates ATP during short, hard efforts. Practically, that means a few more reps per set, which compounds into more strength and lean mass over months.
Beyond training
Trials in sleep-deprived and cognitively loaded subjects show small improvements in working memory and reaction time. Effects in well-rested young adults are minimal, the benefit shows up when the system is stressed.
The dose
- 3 to 5 g daily of creatine monohydrate, timing irrelevant
- Optional loading: 20 g a day split across four doses for 5 to 7 days
- Buffered, liquid and "HCl" versions cost more and outperform nothing
Safety
Reviews covering trials up to five years find no adverse effect on kidney or liver function in healthy adults. Existing kidney disease is the exception, that warrants a conversation with your clinician first.
The 1 to 2 kg of early weight gain is intracellular water, not fat.
Frequently asked
Does creatine cause hair loss?
The claim traces to one small 2009 rugby study measuring DHT, not hair. No trial since has shown hair loss as an outcome.
Do I need to cycle it?
No. Continuous daily use is what the long-term safety data covers, and stopping simply lets stores fall back to baseline.
