Creatine for perimenopause — the honest evidence picture
The 2025 CONCRET-MENOPA trial changed the picture. What the evidence says about creatine and brain fog in perimenopause.

Why this is not a gym supplement
Creatine has a reputation problem. For most people, it is the thing bodybuilders take to build muscle.
That framing is about to change. The most interesting recent research on creatine is not about muscle. It is about the brain. And it is being done specifically in perimenopausal and menopausal women.
What creatine does in the brain
The brain uses around 20% of your body's total energy. It runs on ATP. Creatine helps the brain store and regenerate ATP more efficiently.
Oestrogen plays a role in creatine synthesis and creatine transporter expression in the brain. As oestrogen declines in perimenopause, brain creatine availability may decrease.
"Brain fog" is one of the most reported perimenopause symptoms. For most women, it does reverse. But the mechanism is the same as what creatine targets.
The 2025 CONCRET-MENOPA trial
The CONCRET-MENOPA trial, published in the Journal of the American Nutrition Association in 2025, was an 8-week randomised controlled double-blind trial in 36 perimenopausal and menopausal women.
The medium-dose group (1,500mg creatine hydrochloride per day) showed:
- Significant improvement in reaction time (6.6% improvement vs 1.2%, p < 0.01)
- Brain creatine levels in the frontal cortex increased by 16.4% versus 0.9% in placebo
- Potential benefit for mood swing severity (p = 0.06, trending)
- Favourable changes in serum lipid profiles
This is the first RCT specifically in perimenopausal and menopausal women examining cognitive outcomes.
What form, what dose
Creatine monohydrate is the most studied form. Safe, affordable, effective. Standard dose: 3-5g daily. No loading phase needed for women.
Creatine hydrochloride (HCl) is more soluble and requires a lower dose. The CONCRET-MENOPA trial used 1,500mg daily and found significant brain effects.
Take it daily with a meal. Consistency matters more than timing.
What creatine does not do
It is not a hot flush treatment. No evidence supports this.
It is not a weight loss intervention. Some women report scale weight going up initially due to water retention in muscle. This is normal.
It will not replace HRT. It works on brain energy metabolism. It does not address declining oestrogen.
Evidence summary
| Outcome | Grade | Notes |
|---|---|---|
| Brain creatine levels | Strong | 2025 RCT, direct measurement |
| Cognitive function / reaction time | Strong | 2025 RCT in perimenopausal women |
| Mood swing severity | Moderate | 2025 RCT trending; not yet significant |
| Muscle strength | Strong | Multiple RCTs, mainly postmenopausal |
| Hot flushes | No evidence | Not studied |
