Creatine for perimenopause
Creatine is one of the few supplements with real, recent evidence in this life stage, including 2026 trial work in menopausal women. These guides cover what it does, how to take it, who it helps most, and how the products marketed to women 40 and over actually differ.

- Creatine for perimenopause: what the evidence actually showsFor most women in perimenopause, creatine monohydrate at 3-5 grams a day is a reasonable, well-studied addition, especially alongside resistance training.
- The best creatine for women over 40For most women over 40, plain creatine monohydrate powder is still the best creatine: it has by far the largest evidence base, costs the least per dose, and works as well as or better than every newer form tested against it.
Creatine in perimenopause at a glance
Creatine is a compound your body makes and stores mostly in muscle, where it helps refuel short bursts of effort. Falling estrogen is linked to faster loss of muscle and strength, and it appears to lower natural creatine stores somewhat, which is why researchers have started testing it in women in and after the transition.
The short version: creatine monohydrate at 3-5 g a day is well studied and low risk, and it works best alongside resistance training. It will not fix hot flashes or mood swings.
| Study | Who | What they took | What happened |
|---|---|---|---|
| 2025 systematic review and meta-analysis | Postmenopausal women | 5 g a day or more, with resistance training | About 0.37 kg more lean mass and roughly 7.5 kg more leg-press strength than training alone. Lower doses without training showed no measurable effect. |
| CONCRET-MENOPA, 2025 (randomized, placebo-controlled) | 36 perimenopausal and menopausal women | 1,500 mg a day of creatine hydrochloride | Better reaction time than placebo and higher frontal brain creatine on imaging. A possible edge on mood swings did not reach statistical significance. |
| JISSN pilot, 2025 (no placebo group) | 15 women, average age 54 | 5 g a day of monohydrate plus two strength sessions a week for 14 weeks | Lower-body strength gains, better sleep in the perimenopausal subgroup and modest cognitive changes. Promising, not definitive. |
It is most worth trying if you do, or plan to do, resistance training and want to protect strength and muscle through the transition. It is a reasonable low-risk add-on if brain fog or fatigue bother you, with modest expectations. It is not a substitute for sorting out sleep, hormone status or other causes of fatigue.
Safety looks good. A large review found no increase in serious adverse events, kidney or liver problems, or excess weight gain in women taking creatine monohydrate. Check with a doctor first if you have kidney disease. The early 1-2 pounds some women see is water stored inside muscle, not fat, and skipping a loading phase keeps it smaller.
Which form? Plain monohydrate has by far the largest evidence base and the lowest cost per dose, and no newer form has been shown in independent research to build more muscle at an equal dose. Micronized powder, gummies or flavored versions are for comfort and convenience, not better results. The hydrochloride form is the one the cognition trial used.
