Creatine After Menopause: What 608 Women Across 7 Trials Showed
Seven randomized controlled trials. 608 women. One pooled question: does creatine monohydrate do anything measurable for women after menopause?
A 2026 systematic review and meta analysis in the Journal of the International Society of Sports Nutrition went looking. It is a pooled read across two decades of trials, and it is honest about where the evidence runs out.
THE STUDY
- Title: Creatine monohydrate for lean mass, strength, and bone density in postmenopausal women: a systematic review and meta-analysis
- Journal: Journal of the International Society of Sports Nutrition, 2026
- Authors: Naddafha S, Antonio J, Kreider RB, Stout JR
- Design: Systematic review and random effects meta analysis of randomized, placebo controlled trials

WHO WAS IN IT
Seven randomized controlled trials, 608 women randomized, mean age roughly 62. Six databases were searched from 2000 through August 2025, with trial registries and reference lists swept on top of that. Trials had to run at least six weeks to count toward the primary analysis. The ones that made it ran 12 to 104 weeks, median 38 weeks.
This is not a single lab's result. It is what happens when you line up two decades of trials next to each other and ask them to agree.
WHAT THEY TOOK
Creatine monohydrate, with or without resistance training, at the doses each original trial chose. That range turned out to matter more than anything else in the paper.
WHAT THEY FOUND
- Lean mass: creatine came out ahead by 0.37 kg (5 trials, 338 women, 95% CI +0.05 to +0.69)
- Leg press strength: one rep max improved by 7.5 kg (3 trials, 111 women, 95% CI +2.2 to +12.8)
- Dose and training together: the benefit showed up when 5 grams a day or more was paired with resistance training. Trials using 3 grams a day or less, with no training, showed no measurable effect
- Bone density: unchanged overall
- Safety: adverse events were mild and similar to placebo, and kidney markers did not move
The authors' own summary line: creatine, particularly at 5 grams a day or more with resistance training, "yields small but meaningful gains in lean mass and strength without evidence of harm."
WHAT IT DOES NOT SHOW
Four things worth holding onto, because a meta analysis is a summary of uncertainty as much as it is a summary of results.
- Small is still small. 0.37 kg of lean mass is a real number, not a dramatic one. The authors call the gains "small but meaningful" and we are not going to inflate that
- The prediction interval crosses zero. For lean mass it ran -0.10 to +0.84, which means a future trial landing at no effect would not be a shock
- Creatine was not working alone. Resistance training was in the room for the trials that moved. Without it, at low doses, nothing measurable happened
- Bone is unresolved. The paper says effects on bone density "remain unclear." Not disproven, not shown. Unclear
Funding and conflicts, stated plainly: the authors disclose creatine research ties, one chairs a scientific advisory board supported by a creatine manufacturer, one is chief executive of the nonprofit that publishes the journal, and that same manufacturer covered part of the publication fee. All of that is disclosed in the paper itself. It does not void the analysis and it is not something you should have to dig for.
WHY IT IS ON THIS SHELF
Because most of the creatine research a shopper runs into was done on young men, and this one was not. Women after menopause have been asking whether any of it applies to them, and this is the closest thing to a straight answer that exists right now.
It is also a dose story. The trials that worked used 5 grams a day or more, alongside training. Each four gummy serving of Vybrance Labs creatine gummies delivers 5g of creatine monohydrate, which is the research standard, plus B12 and taurine. The training part is still yours to do.
