Creatine in Perimenopause and Menopause: What Trials Show

With resistance training, creatine at 5 g (grams) a day or more added 0.37 kg of lean mass and 7.5 kg to a leg press across seven postmenopausal trials of 608 women; 3 g a day without exercise changed nothing measured over two years in 200 women.¹ Perimenopause has one small trial, and hot flushes, sleep and HRT have never been studied in a creatine trial.²

• Strength and muscle: small gains, only in the trials that paired creatine with training¹
• Bone: density unchanged in the longest trial; one bending-strength measure of the hip held³
• Peri, mood and HRT: one 36-woman trial of a creatine salt; brain fog and HRT never studied

Is creatine good for menopause and perimenopause?

The NHS puts it plainly: "Perimenopause happens when your periods become irregular and menopause is when your periods stop altogether", usually between 45 and 55.⁴ Its symptom list includes "muscle aches and joint pains", "weakening bones (loss of bone density), which can lead to osteoporosis" and "poor memory and brain fog".⁵ Two women's-health reviews propose that falling oestrogen changes how the body makes and handles creatine, a hypothesis the trials below test; the 2025 review says itself that "data on perimenopausal women remains limited".^{6, 7} No supplement may claim to ease menopause symptoms in the UK, so this page reports what was measured; which menopause supplements have evidence covers flushes and sleep, and the earlier life stage is on can you take creatine while pregnant or breastfeeding.

What do trials show for strength and muscle after menopause?

Menopause "is accompanied by accelerated losses in muscle mass and strength", as the 2026 meta-analysis opens.¹ Its seven randomised trials, 608 women of about 62 on average, ran 12 to 104 weeks. The women who trained and took 5 g or more a day gained 0.37 kg more lean mass (five trials, 338 women) and 7.5 kg more on a leg press (three trials, 111 women) than placebo; the women who took 3 g a day without training for two years did not change, which is a finding about training, not about creatine.^{1, 8} In the largest trial, 237 women over two years at 0.14 g per kilogram a day with training three days a week, creatine made no difference to the heaviest single lift, but the women walked 80 m faster.³

One benefit sentence is authorised in Great Britain for this age group: "Daily creatine consumption can enhance the effect of resistance training on muscle strength in adults over the age of 55."⁹ Its conditions are the point: 3 g of creatine a day, with resistance training that increases the load over time, at least three times a week for several weeks, at 65 to 75% of the most you can lift once. It needs the training.

Does creatine protect bone? Osteoporosis and the two-year trial

Osteoporosis is what older women ask about, and creatine has been tested against post-menopausal bone loss three times. In a 12-month trial of 47 women training under supervision at 0.1 g per kilogram a day, the 33 completers lost 1.2% of femoral neck density on creatine against 3.9% on placebo.¹⁰ The same team's two-year trial in 237 women found no effect on bone mineral density at the femoral neck, total hip or lumbar spine; two geometric measures at the femoral neck, the section modulus and the buckling ratio, held on creatine and worsened on placebo.³ And in 200 women with osteopenia taking 3 g a day for two years with no exercise programme, nothing measured, from bone density to falls and fractures, differed from placebo, which the authors say "refutes the long-lasting notion that this dietary supplement alone has osteogenic or anabolic properties"; the training trials are where the measurable gains were.⁸

The whole finding: bone density did not change in the longest trial; a bending-strength measure did, and the pooled analysis calls density "unchanged overall".¹ Creatine is not a treatment for osteoporosis; anyone with a diagnosis stays on what their GP prescribes. Collagen's bone trials in the same women are on collagen and the menopause.

Memory, mood and sleep in perimenopause: what has been measured?

One trial has recruited perimenopausal women. In 2026, 36 perimenopausal and menopausal women, about nine per group, took creatine hydrochloride at 750 mg or 1,500 mg a day, a hydrochloride and ethyl-ester blend at 800 mg a day, or placebo for eight weeks. The 1,500 mg group had a faster reaction-time result than placebo (1.2% against 6.6%), a rise in frontal-brain creatine of 16.4% against 0.9%, and a change in mood swings that did not reach significance (p=0.06).² One small trial of a creatine salt at sub-gram doses, never compared with monohydrate, ranks no form above another. The monohydrate trial in older women, 56 women for 24 weeks at 5 g a day with or without training, altered no cognitive or emotional measure; training lowered depression-scale scores and creatine added nothing.¹¹ Brain fog, hot flushes, night sweats and sleep have never been recorded as an outcome in a creatine trial. The cognition counts and the register's refused cognition claim are on creatine and the brain.

Can you take creatine with HRT, and does it affect oestrogen?

No study has looked at creatine alongside hormone replacement therapy: the two long trials did not report whether their women took it, and no interaction has been studied or reported. The rule is the one for any supplement: tell whoever prescribes your HRT, and your GP, what you take. No trial read for this page measured oestrogen in women; the reviews propose that hormones change how the body handles creatine, not the reverse.⁶ Creatine also causes a small rise in serum creatinine, the reading used to check kidneys, while kidney markers stayed unchanged across the postmenopausal trials,¹ so before any blood test say to the GP, practice nurse or pharmacist: "I take a creatine supplement; it can raise the creatinine reading." Creatine vs creatinine explains the rest, and does Mounjaro affect the pill, HRT and menopause covers anyone also on a weight-loss injection.

How much creatine, and when?

No menopause-specific dose exists, because no trial has tested one. The two Canadian training trials used 0.1 to 0.14 g per kilogram of bodyweight a day; the trials the pooled analysis found positive used 5 g a day or more.^{1, 3, 10} The register's condition is 3 g (grams) a day, at which creatine carries the GB performance wording for adults performing high-intensity exercise, "Creatine increases physical performance in successive bursts of short-term, high intensity exercise", and for over-55s the strength wording above, with its training conditions.⁹ Take it every day, at any time, including rest days; drink normally, as no water target is evidenced. The bodyweight table is on how much creatine should you take; what creatine does explains the store it fills.

Is creatine good for women over 40 and over 50?

The evidence above is the answer: one small perimenopausal trial, then seven postmenopausal training trials. Should a 55-year-old woman take it? If she trains, the register's over-55 sentence applies to her, with its conditions. If she does not, the two-year 3 g trial found no change in anything it measured.⁸ Creatine for women keeps the summary across every life stage.

Frequently asked questions

Should a menopausal woman take creatine?

With resistance training the trials found small gains in lean mass and leg strength; without it the two-year trial found none.^{1, 8} Kidney disease or regular medication means GP first.

Does creatine help with menopause belly fat?

No trial in this group measured fat loss, and in a 24-week trial of 60 older women fat mass did not differ between groups.¹² The roughly 1.2 kg weight difference in pooled trials of women, not statistically significant, is water in muscle; does creatine make you gain weight explains the scale.¹³

Does creatine cause hot flushes?

No trial has recorded hot flushes as an outcome, so there is no evidence either way; the perimenopause trial admitted women with hot flushes but did not report them as a result.²

Is creatine safe for women?

Across 29 studies that monitored 951 women there were no deaths or serious adverse outcomes, and gut side effects matched placebo (risk ratio 1.09).¹³ In the postmenopausal trials adverse events were mild and kidney markers unchanged.¹

Which creatine should a woman over 50 choose?

Every postmenopausal trial above used creatine monohydrate, as did the trials on creatine for men; there is no women's or menopause creatine. Read the ingredients line for "creatine monohydrate" and the grams per daily serving, whatever the format.
