Should women take creatine?
Yes, at the same 3 to 5 g a day, and with lifting. In a 2026 pooling of trials in women after menopause, leg press rose about 16 lb (7.5 kg) more with creatine, and lean mass rose a little. Bone density didn’t change, so it’s a strength supplement for women, the same as for men.
Creatine has two reputations among women. One is that it’s a guy’s supplement that makes you puffy. The other, mostly on supplement blogs, is that it’s a fix for menopause, bones, mood and brain fog all at once. The trials land somewhere much more useful and much more modest.
What we’d do
Lift two or three days a week and take 3 to 5 g of creatine a day with it. Expect a small edge in strength, and don’t count on it for your bones. Pregnant or breastfeeding, ask your doctor first.
What it does after menopause
In 2026 Siavash Naddafha, with Jose Antonio and two other creatine researchers, pooled seven randomized trials with 608 women, average age about 62.
| Measure | Extra change with creatine |
|---|---|
| Lean mass | About 0.8 lb (0.37 kg) more |
| Leg press, one-rep max | About 16 lb (7.5 kg) more |
| Bone density | No change |
| Kidney measures | No change |
The gains showed up when women took at least 5 g a day and lifted. Trials at 3 g a day or less without lifting found nothing. Side effects were mild and about the same as placebo.
The two-year trial
The longest test is a trial led by Philip Chilibeck. 237 women who’d been through menopause, average age 59, took creatine (about 0.14 g per kg a day, around 10 g at 154 lb) or a placebo for two years, while lifting three days a week and walking six.
Bone density at the hip and spine came out the same in both groups. But creatine kept one measure of how strong the hip bone is from falling, and the women on creatine got faster on an 80 m walk, from 48.6 to 47.1 seconds, while the placebo group stayed at about 48. Bench press and machine squat strength rose the same in both groups.
It’s like a better pair of running shoes. They won’t change the bones in your feet, and they might take a second off your walk.
The sceptic’s point
Across 35 mixed trials of men and women, men on creatine gained about 3.2 lb (1.46 kg) more lean mass, and women about 0.6 lb (0.29 kg), which was too small to be sure of. The postmenopause trials hint at a reason, since the benefit only showed up with at least 5 g a day plus lifting. It’s still a small effect.
Most creatine trials in women have been after menopause. A 2025 review of creatine in women’s health says data in perimenopause are still limited, and the evidence in pregnancy is only emerging.
Water and the scale
Women gain creatine water too. A 2003 trial of 16 women and 16 men who lifted found body water rose 1.37 L in the first week of loading. Skip loading if the scale bothers you, and the rise spreads out over four weeks instead.
