The claim

“Creatine helps women get stronger.”

Mostly true
Evidence confidence Limited
The short answer

Creatine helps women get a little stronger when they also strength train, but the gains are small and the studies are small and mixed.

What this means for you

If you lift weights, creatine can add a small extra strength gain. It is a modest bonus on top of training, not a shortcut.

Your next step

If you want to try it, take about 5 grams of creatine monohydrate a day alongside a regular strength-training routine.

Who should be careful?

Talk to a healthcare professional if: you have kidney disease, or you are having blood tests of kidney function, because creatine can raise creatinine, the marker those tests use.

The evidence
Why this confidence?

Reviews of trials in women find a small strength benefit when creatine is added to strength training, and the clearest gains are in postmenopausal women who lift. Confidence is limited because the trials are small and varied, and one review of younger adults found no clear gain in women.

The facts

Creatine helps women get a little stronger when they also strength train, but the gains are small and the studies are small and mixed. It adds to training rather than replacing it.

The bigger picture

A 2026 review of 34 studies in 692 women who exercise found a small benefit for strength, power and high-intensity performance, with low certainty. Another 2026 review of 7 trials in 608 postmenopausal women found about 16.5 pounds more on the leg press than placebo, mainly when women took 5 grams a day or more and did strength training; low doses without training showed no effect. One review of adults under 50 found clear strength gains in men but not in women, although only a few dozen women were studied. Most creatine research has been done in men.
