Creatine Research: What the Science Says (and Doesn't)

What the science says about creatine. And what it doesn’t.

The short answer

Creatine is one of the most researched supplements in sports nutrition. The strongest evidence shows that, combined with resistance training, it helps adults gain more strength than training alone. Research in women after menopause and in brain health is growing. Most studies use 3–5g a day.

01 — The basics

What is creatine?
Five quick facts.

Creatine isn’t a new trend. It’s a compound your body already makes, and one of the most studied supplements there is.

  • 2–4g

    Daily turnover

    A compound stored in your muscles. Your body uses about 2–4g a day.

  • ~50%

    Made by you

    About half is made by your body. Most of the rest comes from meat and fish.

  • 3–5g

    In most studies

    The daily amount used in most long-term research, taken consistently.

  • Mono­hydrate

    Most studied form

    Creatine monohydrate is the form behind almost all the research.

  • Daily

    Beats timing

    Loading is optional. Consistency matters more than time of day.

02 — The evidence

How strong is the evidence for creatine?

Not all creatine research is equal. Here’s where each area stands today, based on the studies in our library below.

  • Evidence level: Well supported

    Does creatine increase strength?

    Yes, when combined with resistance training. This is backed by multiple large meta-analyses in adults. Creatine works alongside training, not instead of it.

  • Evidence level: Growing

    Does creatine help women keep muscle after menopause?

    A 2026 meta-analysis of 608 postmenopausal women found small but real gains in lean mass and leg strength, best with at least 5g a day plus resistance training.

  • Evidence level: Growing

    Does creatine help the brain?

    A fast-growing area of research, including studies on memory and sleep loss. Results so far are mixed, and many studies used much higher doses than everyday use.

  • Evidence level: Early research

    Does creatine help bones?

    A 2-year trial in postmenopausal women found no change in bone density, but some measures of bone strength at the hip were maintained. Promising, not proven.

03 — Creatine for women

Does creatine work for women?

It’s the question we’re asked most, especially around menopause. The honest answer: the research is promising, and it’s growing fast.

608

postmenopausal women across 7 randomised trials in a 2026 meta-analysis. Creatine plus resistance training added small but real gains in lean mass and leg strength.

  1. Muscle and strength after menopause

    This is the strongest evidence for women. Benefits showed up most in studies using at least 5g a day alongside resistance training. Bone density didn’t change.

  2. Bones

    In a 2-year trial of 237 postmenopausal women, creatine didn’t change bone density. It did help maintain some measures of bone strength at the hip, and walking speed improved.

  3. Menopause symptoms and hormones

    Still very early. One small 8-week trial in 36 peri- and postmenopausal women found faster reaction times, but most symptoms didn’t change. We haven’t found reliable studies on period pain yet.

  4. Younger active women

    Fewer studies, and mixed results so far. Researchers at Australian Catholic University are calling for better-designed trials, and we’ll add them here as they’re published.
