Creatine boosts reaction time in trial
- Researchers at the University of Novi Sad published the CONCRET-MENOPA trial, testing low-dose creatine in 36 peri- and postmenopausal women over 8 weeks. - The clearest signal came from 1,500 mg/day creatine HCl — reaction time improved 6.6% versus 1.2% on placebo, and frontal brain creatine rose 16.4%. - It matters because menopause-related brain fog has few targeted treatments, but this was small, short, and partly tied to branded formulations.
Creatine is usually filed under gym supplements. But this study is really about brain energy during menopause — and whether a cheap, familiar compound can help with the “brain fog” a lot of women describe. In the CONCRET-MENOPA trial, researchers at the University of Novi Sad randomized 36 peri- and postmenopausal women to placebo or one of three low-dose creatine regimens for 8 weeks. The standout result came from 1,500 mg/day of creatine hydrochloride: faster reaction time and higher frontal brain creatine, with no severe adverse effects reported.

Men(nutrition-evidence.com)ying this in the first place. (sciencedirect.com) ### What did the trial actually test? This was a randomized, double-blind, placebo-controlled trial — a solid design, even if the sample was small. The 36 participants had a mean age of about 50 and were assigned to one of four groups: 750 mg/day creatine HCl, 1,500 mg/day creatine HCl, 800 mg/day creatine HCl plus creatine ethyl ester, or placebo. The trial is registered as NCT06660004 and is listed as completed. (nutrition-evidence.com) ### What changed the most? Reaction time was the cleanest win. The medium-dose creatine HCl group improved by 6.6%, versus 1.2% in the placebo group. Frontal brain creatine also rose 16.4% in that group, versus 0.9% with placebo. The paper also notes favorable changes in serum lipids and a possible reduction in mood swings, though the mood result sat right on the edge statistically. (nutrition-evidence.com) ### Does that mean creatine fixes brain fog? Not so fast. Reaction time is one piece of cognition, not the whole thing. This was not a big, long trial measuring everyday function over months or years. And the participants were split across four groups, which means each arm was very small. So the result is interesting because it gives a measurable signal in both behavior and brain chemistry — kind of a two-lock match — but it is still an early signal. (nutrition-evidence.com) ### Why does the brain-creatine result matter? Because it suggests the supplement may actually be changing fuel availability in the brain, not just nudging test performanc(nutrition-evidence.com)stionnaire shift. (nutrition-evidence.com) ### Is this the same as the creatine people take for lifting? Not exactly. The best result here came from creatine hydrochloride at 1,500 mg/day, not the more familiar creatine monohydrate. That matters because different forms have different dosing conventions and marketing claims. But it also creates a catch — this study does not tell you that any creatine product on a store shelf will reproduce the same effect. (nutrition-evidence.com) ### So what should readers take from this? The real news is not “creatine cures menopause brain fog.” It is narrower than that. A small 2025 randomized trial found that one low-dose creatine HCl regimen improved reaction time and raised frontal brain creatine in midlife women over 8 weeks. That makes creatine look like a plausible adjunct worth testing harder next — not a settled answer, but no longer just gym lore either. (nutrition-evidence.com)
