Why More Women Are Taking Creatine: The Benefits for Muscle, Brain Health and Menopause

For decades, creatine lived firmly in the bodybuilding aisle. It was associated with protein shakers, weight rooms and men trying to gain muscle, while many women avoided it altogether, worried that taking creatine might make them bulky, heavier or bloated.

That perception is changing rapidly. Creatine is increasingly being discussed not simply as a sports supplement, but as a potential tool for supporting women’s strength, muscle function and healthy ageing, with researchers also investigating possible benefits for cognition, mood and the brain.

Interest is particularly growing among women approaching perimenopause and menopause, a stage of life when maintaining muscle, strength and bone health becomes increasingly important. A major review specifically examining creatine across the female lifespan concluded that hormonal changes may influence creatine metabolism and that supplementation could have particular relevance during different reproductive stages and after menopause.

So, has creatine been misunderstood by women for years? And should it now be considered alongside protein, resistance exercise, sleep and good nutrition as part of a healthy ageing strategy?

The science is certainly interesting, although—as with most areas of nutrition—the answer is more nuanced than some social-media claims suggest.

What is creatine?

Creatine is a naturally occurring compound made from amino acids. Our bodies produce it primarily in the liver and kidneys, and we also obtain creatine through foods including meat and fish.

Most of the body’s creatine is stored in skeletal muscle, where it helps regenerate adenosine triphosphate, or ATP—the energy currency cells use to perform work. In simple terms, the phosphocreatine system provides a rapid reserve of energy when our muscles need to work hard.

That explains why creatine has such a long history in sports nutrition. Increasing the amount of creatine available inside muscle can help people perform repeated bouts of high-intensity activity and, particularly when combined with resistance training, support improvements in strength and lean body mass. Creatine monohydrate is among the most extensively researched sports supplements available.

But muscles are not the only organs with large energy demands.

The brain also uses enormous amounts of energy, which is one reason researchers have become increasingly interested in whether increasing creatine availability could affect cognitive performance and neurological health.

Why are more women taking creatine now?

Part of creatine’s reinvention comes from a much wider conversation about women’s health.

Women are increasingly being encouraged to think about muscle as an important component of long-term health rather than simply something associated with appearance or athleticism. Maintaining strength becomes particularly relevant as we get older, while resistance training is now moving into the mainstream conversation around menopause and healthy ageing.

Research examining creatine specifically in women has consequently expanded. A 2021 review published in the Journal of the International Society of Sports Nutrition concluded that premenopausal women may experience improvements in strength and exercise performance with creatine supplementation, while postmenopausal women may potentially experience benefits relating to skeletal muscle size and function when creatine is combined with resistance training.

A more recent review published in 2025 described growing evidence around women’s health but also highlighted an important limitation: considerably more research is still needed, particularly in perimenopausal women.

In other words, creatine has not suddenly acquired completely new properties. Instead, researchers are beginning to ask broader questions about a compound that has historically been studied predominantly through the lens of sports performance.

What are the benefits of creatine for women?

Creatine may help women maintain muscle and strength

The strongest argument for creatine remains its relationship with skeletal muscle.

Women typically have less absolute muscle mass than men, and maintaining muscle becomes increasingly important with age. Resistance training remains one of the most important interventions for preserving strength, but creatine may help enhance some of the adaptations produced by training.

A 2026 systematic review and meta-analysis examining creatine in postmenopausal women concluded that creatine—particularly doses of at least 5g per day when combined with resistance training—produced small but potentially meaningful improvements in lean mass and strength without evidence of harm.

This distinction matters. Creatine should not be thought of as something that simply builds muscle while you continue living exactly as before.

Its value appears considerably more compelling when it accompanies regular resistance exercise.

Think of strength training as the stimulus and creatine as one possible nutritional tool that may support the body’s response to that stimulus.

Can creatine help during perimenopause and menopause?

This is probably one of the reasons creatine has attracted so much attention from women recently.

Menopause is associated with physiological changes that can affect muscle, bone and body composition. Maintaining adequate protein intake, participating in weight-bearing and resistance exercise, sleeping well and supporting overall metabolic health therefore become increasingly important.

Creatine may eventually form another part of that toolkit.

Research investigating postmenopausal women suggests that combining creatine with resistance training may support muscle mass and strength. However, researchers reviewing female-specific evidence in 2025 cautioned that direct evidence in perimenopausal women remains limited.

That is an important reality check amid the current enthusiasm.

There is good biological reasoning for researching creatine during menopause, and early findings are encouraging, but we should not jump from “promising” to “proven treatment for menopause symptoms”.

What about creatine and bone density?

Bone health is another area where claims can get ahead of the science.

One earlier 12-month trial involving postmenopausal women found that creatine combined with resistance training helped preserve femoral-neck bone mineral density and favourably affected aspects of bone geometry.

However, subsequent research has been less conclusive.

A two-year randomised controlled trial found that creatine combined with exercise did not improve bone mineral density overall, although some measures of bone geometry improved. Another long-term study involving postmenopausal women with osteopenia found no significant improvement in bone health from 3g of creatine per day.

The latest evidence therefore suggests that creatine should not currently be viewed as a substitute for established bone-health strategies.

Resistance and impact exercise, adequate protein and nutrition, vitamin D and calcium where appropriate, avoiding smoking, moderating alcohol consumption and seeking medical assessment where osteoporosis risk is elevated remain much more important.

Creatine may ultimately prove useful as part of a broader strategy, but the effect on bone density itself remains uncertain.

Could creatine support brain health and cognitive function?

This is where the creatine story becomes especially interesting.

The brain requires a constant supply of energy, and researchers have been exploring whether increasing creatine availability could improve the brain’s ability to meet particularly demanding situations.

A 2024 systematic review and meta-analysis concluded that creatine monohydrate supplementation may have beneficial effects on aspects of cognitive function including memory, attention and processing speed, while also emphasising that larger high-quality trials are still required.

The evidence does not suggest that taking a scoop of creatine automatically makes a healthy, well-rested person noticeably more intelligent. Indeed, earlier research in healthy young adults has sometimes found no cognitive improvement at all.

Where the story becomes particularly interesting is during periods when the brain is under greater energetic stress.

Creatine, tiredness and sleep deprivation

Anyone navigating work, family life, hormonal changes and disrupted sleep will understand why this area has attracted attention.

Research published as far back as 2006 found that creatine supplementation following 24 hours of sleep deprivation had beneficial effects on some cognitive tasks and mood measures.

More recently, controlled research has found improvements in cognitive performance and processing speed during sleep deprivation after creatine administration, reinforcing the hypothesis that creatine may become particularly relevant when the brain’s energy demands are challenged.

Intriguingly, a 2026 study examining a single dose during sleep deprivation reported reduced deterioration in several cognitive tasks, with female participants appearing to experience greater benefits than males in some measures. This is fascinating research, but it should not be interpreted as a reason to replace sleep with creatine.

Sleep remains fundamental to health. Creatine is being investigated for how the brain copes with metabolic stress—not as an antidote to chronically inadequate rest.

Does creatine cause weight gain?

This remains one of the biggest concerns among women considering creatine.

Creatine can cause an increase in body weight, particularly when somebody first begins taking it, because increasing muscle creatine can also increase the amount of water held within muscle cells.

That is very different from gaining body fat.

The International Society of Sports Nutrition’s evidence review identifies body-mass gain as a recognised effect of creatine supplementation while rejecting many of the more alarming myths that have historically surrounded the supplement.

This water is primarily associated with the muscle rather than creatine simply causing somebody to become generally “puffy”.

For women who regularly weigh themselves, however, it is worth understanding this before starting supplementation. A small change on the scales does not automatically mean body composition has worsened.

In fact, if your wider objective is healthy ageing, preserving metabolically active muscle may be considerably more meaningful than pursuing the lowest possible number on a set of bathroom scales.

Will creatine make women bulky?

Creatine cannot magically create large muscles.

Meaningful increases in muscle require progressive resistance training, adequate nutrition, recovery, genetics, time and an appropriate hormonal environment. Creatine can support training adaptations, but it does not transform a woman’s body overnight.

Ironically, fear of becoming “too muscular” may have discouraged generations of women from something increasingly recognised as valuable for ageing well: becoming stronger.

Our goal as we move through midlife perhaps needs to change from simply becoming smaller to remaining capable—being able to lift, carry, climb stairs, travel, exercise, recover from illness and remain physically independent later in life.

Within that broader conversation, muscle starts to look less like a cosmetic concern and more like an investment in the future.

How much creatine should women take?

For most healthy adults choosing to supplement, 3–5g of creatine monohydrate per day is the commonly researched maintenance range. Evidence reviews have consistently found this dosage to be effective and generally well tolerated.

Some sports protocols use a “loading phase” of around 20g per day divided into several smaller doses for approximately five to seven days before moving to a maintenance dose.

Loading is not essential.

Taking a smaller daily amount will also gradually increase muscle creatine stores; it simply takes longer.

For someone approaching creatine primarily from a general wellbeing or healthy-ageing perspective rather than trying to maximise sporting performance rapidly, simplicity and consistency may be more useful than an elaborate loading protocol.

When should you take creatine?

Creatine does not need to be treated like a stimulant or timed immediately before exercise.

Regular daily consumption is more important than finding the supposedly perfect minute to take it.

Some people stir creatine into water, while others add it to smoothies, yoghurt or another drink and simply incorporate it into an existing morning or post-workout routine.

Because creatine works by gradually increasing the body’s creatine stores, consistency matters more than chasing complicated timing strategies.

What is the best type of creatine?

Despite an ever-growing collection of products promising advanced absorption, enhanced bioavailability and premium formulations, creatine monohydrate remains the form with by far the strongest evidence base.

Reviews examining commonly repeated creatine claims have found no compelling evidence that alternative forms consistently outperform creatine monohydrate.

That also makes shopping surprisingly simple.

Look for creatine monohydrate, preferably as a straightforward product without unnecessary proprietary blends or extravagant claims.

Creatine powder versus creatine gummies

Creatine gummies may appear convenient, but this is one area where consumers should pay particularly close attention to product quality.

In 2025, supplement tracking and rating platform SuppCo purchased five creatine powders and six popular creatine gummy products and sent them to an independent ISO 17025-accredited laboratory. All five powders passed its potency and purity testing, while four of the six gummy products failed identity and potency testing, with some containing virtually no creatine.

This was one independent testing exercise rather than a peer-reviewed clinical trial, so it should not be interpreted as evidence that every creatine gummy is ineffective.

It does, however, demonstrate why independent verification matters.

A colourful packet, thousands of online reviews and an impressive influencer campaign cannot tell you whether a supplement actually contains what its label promises.

Why third-party supplement testing matters

Unlike a scientific paper, a supplement label is ultimately a manufacturer’s claim.

Independent certification provides another layer of assurance.

The US National Institutes of Health Office of Dietary Supplements identifies organisations including NSF International and US Pharmacopeia among bodies providing independent supplement-quality testing. Such testing can help establish whether products are manufactured appropriately, contain the ingredients stated on their labels and avoid harmful levels of certain contaminants. Importantly, certification does not prove that a supplement will deliver the health benefits claimed in its marketing.

When shopping, therefore, look beyond attractive branding and ask a different question:

Can the company demonstrate what is actually inside this product?

What should you look for when buying creatine?

For most people, choosing creatine does not need to be complicated. Look for a product that clearly states creatine monohydrate and the precise dose per serving rather than hiding ingredients inside proprietary blends.

Look for recognised independent testing or certification where available, particularly if you are an athlete subject to anti-doping rules. NSF’s Certified for Sport programme, for example, tests products for substances prohibited by major sporting organisations.

Be cautious about dramatic statements such as “10x absorption”, “fat-burning creatine” or claims that a proprietary form is dramatically superior unless the company can provide strong independent evidence supporting them.

And don’t assume the most expensive product must be the best. With creatine, paying for elaborate packaging or a fashionable delivery format does not necessarily improve the ingredient itself.

Is creatine safe for women?

Creatine has a substantial body of safety research behind it.

A major International Society of Sports Nutrition review concluded that short- and long-term creatine supplementation has been well tolerated in healthy people across a large body of research.

Kidney health has perhaps generated the most persistent concern.

A 2025 systematic review and meta-analysis found that creatine supplementation can produce a modest increase in blood creatinine but did not produce a significant reduction in glomerular filtration rate, or GFR, an important measure of kidney function. This distinction matters because creatinine is a breakdown product of creatine, meaning a rise in the blood marker does not automatically mean creatine has damaged the kidneys.

People with existing kidney disease, impaired renal function or those taking medications capable of affecting the kidneys should seek individual medical advice before using creatine.

It is also worth telling your doctor that you take creatine if you are having blood tests, because it may help them interpret creatinine results appropriately.

What about creatine during pregnancy or breastfeeding?

Pregnancy is an interesting area of creatine research, but interest in a nutrient is not the same thing as having sufficient clinical evidence to recommend routine supplementation.

Research examining creatine across the female lifespan has highlighted pregnancy as a potentially important area for future study, but human evidence remains insufficient to establish routine creatine supplementation during pregnancy or breastfeeding.

Pregnant or breastfeeding women should therefore discuss supplements with their GP, midwife or an appropriately qualified healthcare professional rather than extrapolating from studies involving athletes or postmenopausal women.

Is creatine worth taking if you don’t go to the gym?

Possibly—but this is where context matters.

Creatine’s strongest established benefits relate to muscular performance and adaptations to exercise, particularly resistance training. If you are taking creatine while doing very little physical activity, you should not expect it to compensate for the absence of movement.

The bigger wellbeing lesson may therefore be less about adding another supplement and more about reconsidering strength itself.

Walking is wonderful. Yoga can improve mobility and body awareness. Cardiovascular exercise supports heart and metabolic health. But as we move through our forties, fifties, sixties and beyond, intentionally challenging our muscles also deserves a place in the wellbeing conversation.

Creatine may support that process.

It cannot replace it.

Creatine and women: the bigger picture

Perhaps the most interesting thing about the current creatine boom is not creatine itself, but what it says about changing attitudes towards women’s health.

For years, much of female wellness culture revolved around taking up less space: eating less, weighing less and becoming smaller.

The conversation is gradually changing.

We are talking about building strength, maintaining muscle, protecting mobility, nourishing ourselves adequately and asking how the habits we establish at 40 or 50 might affect the body we inhabit at 70 or 80.

Creatine fits surprisingly well into that new conversation.

It is inexpensive, extensively researched and appears to offer genuine benefits for strength and muscle when used appropriately, particularly alongside resistance exercise. Its potential effects on cognition, the ageing brain and women’s health across hormonal transitions make it an exciting area of research too.

But it is worth resisting the wellness industry’s tendency to turn promising science into miracle products.

Creatine is not a cure for menopause. It will not replace sleep. It cannot rebuild bone without the wider foundations of nutrition and exercise, and it will not make somebody healthy simply because they add 5g to their morning smoothie.

Viewed instead as one small tool within a much bigger strategy of strength, movement, nourishment and healthy ageing, creatine becomes considerably more interesting.

And that may be why so many women are finally looking at that previously male-dominated tub of white powder and wondering whether it might have belonged in their wellbeing toolkit all along.

Frequently Asked Questions About Creatine for Women

What does creatine do for women?

Creatine helps the body rapidly regenerate cellular energy and is best established for supporting strength, exercise performance and lean muscle when combined with appropriate training. Researchers are also investigating possible benefits relating to cognition, ageing and women’s health.

Is creatine good for women over 40?

It may be particularly relevant as maintaining muscle and strength becomes increasingly important through midlife. Evidence is encouraging in postmenopausal women, especially when creatine is combined with resistance exercise, although research specifically involving perimenopausal women remains comparatively limited.

Does creatine help menopause?

Creatine is not a menopause treatment, but research suggests it may help support muscle and strength during and after the menopausal transition, particularly alongside resistance training. Evidence relating to cognition, mood and bone health is still developing.

Does creatine make women put on weight?

Creatine can increase body weight because more water is stored with creatine inside muscle tissue. This is not the same as gaining body fat.

Does creatine make women bulky?

No. Creatine can support the muscle-building response to resistance training but does not independently create large amounts of muscle.

What is the best creatine for women?

There is no need for a special “women’s creatine”. Creatine monohydrate remains the most extensively researched form, and alternative varieties have not consistently demonstrated superior results.

How much creatine should a woman take each day?

A common evidence-based maintenance dose is approximately 3–5g of creatine monohydrate per day. Individual requirements and medical circumstances vary, so people with health conditions or concerns should seek professional advice.

Do you need to cycle creatine?

There is no established requirement for healthy adults to continually cycle on and off creatine when using conventional doses. Long-term research has generally found recommended creatine supplementation to be well tolerated in healthy individuals.

Should women take creatine every day?

Creatine works by increasing the body’s creatine stores, so consistent daily intake is generally used in research rather than taking it only on workout days.

Can you take creatine if you don’t exercise?

You can, and research into brain health is expanding beyond exercise populations. However, the clearest evidence for musculoskeletal benefits comes from combining creatine with exercise, especially resistance training.

Is creatine safe for kidneys?

Current evidence indicates that standard creatine supplementation does not impair kidney filtration in healthy individuals. People with existing kidney disease or other renal risk factors should seek medical advice before taking it.
