Creatine After 40: Miracle Powder or Actually Worth Taking?

Creatine used to belong to a particular corner of the supplement world.

Big tubs of white powder. Gym bags. Bodybuilders. Men trying to lift increasingly large objects for reasons I’ve never entirely understood.

It certainly wasn’t something I associated with women approaching or going through menopause.

But suddenly creatine seems to be everywhere.

Women over 40 are being told it could help us maintain muscle, improve strength, support our brains, give us more energy and perhaps even make us look younger.

Apparently the bodybuilders have been keeping something from us.

Naturally, I became interested.

Because if there’s something that might genuinely help me maintain muscle and function as I get older — and possibly help my brain on those mornings when I’ve had nowhere near enough sleep — I want to know about it.

But I’ve learnt something while researching products for My Future Face.

Whenever one supplement suddenly appears to do everything, that’s usually the point at which it’s worth looking at what the research actually says.

So I did.

And this one surprised me.

First Things First: What Is Creatine?

Creatine isn’t some strange synthetic substance invented for the fitness industry.

Our bodies naturally make it from amino acids, and we also obtain some through foods, particularly meat and fish.

Much of the creatine in our bodies is stored in skeletal muscle, where it forms part of the system that helps regenerate ATP — adenosine triphosphate, essentially the immediately usable energy currency our cells rely on.

That’s why athletes have used creatine for decades.

When you’re asking your muscles to perform repeated short bursts of high-intensity work — lifting weights, for example — having more readily available energy can help performance.

And this isn’t a new supplement supported by three influencers and an enthusiastic TikTok video.

Creatine is one of the most extensively studied sports supplements available.

But the interesting part for me isn’t what it can do for a 25-year-old bodybuilder.

It’s what it might do for women like me as we get older.

Creatine, Menopause and Muscle

This is where the research becomes genuinely interesting.

We naturally become more vulnerable to losing muscle mass and strength as we age, and menopause adds another layer to that conversation.

Maintaining muscle isn’t simply about looking toned.

Muscle matters for strength, mobility, metabolic health and our ability to remain independent as we get older.

And recent research specifically looking at postmenopausal women is encouraging.

A 2026 systematic review and meta-analysis looked at seven randomised controlled trials involving more than 600 postmenopausal women.

Overall, creatine produced a small increase in lean mass and an improvement in leg-press strength.

But there’s an important detail.

The clearest benefits occurred when women were taking at least 5 g of creatine a day and combining it with resistance training.

In studies using lower doses without resistance training, there wasn’t a measurable benefit.

And I think that’s an important reality check.

Creatine doesn’t appear to be a magic powder that builds muscle while we sit on the sofa watching Netflix.

It seems to work best as an assistant to the work we’re already doing.

Which, annoyingly, means we still have to exercise.

What About Sarcopenia?

You’ll increasingly hear creatine mentioned alongside sarcopenia — the age-related loss of muscle mass, strength and function.

And this is one area where I think the interest in creatine for older women makes sense.

If creatine can help support gains in lean mass and strength when combined with resistance training, it could form one useful part of a wider strategy for maintaining muscle as we age.

But I’d stop short of saying:

Take creatine and you won’t get sarcopenia.

The evidence doesn’t justify that.

Maintaining muscle involves resistance exercise, adequate protein and nutrition, general health and activity — and potentially creatine as an additional tool.

Once again, no miracle powder.

My Experience With Creatine monohydrate

I’ve tried more than one creatine product, ranging from a cheaper option from Holland & Barrett to more expensive formulations.

And I noticed something.

I felt as though I had more energy.

Particularly after a bad night’s sleep.

I’ve also noticed that my concentration can feel better when I’m taking it.

Now, this is where I have to separate my experience from scientific evidence.

There is growing interest in creatine and the brain. Our brains require a great deal of energy, and creatine is involved in cellular energy metabolism there too.

One fascinating study found that a large single dose of creatine improved cognitive performance during sleep deprivation.

But — and this is quite a but — researchers used approximately 0.35 g per kilogram of body weight.

That’s vastly more than my normal 5 g scoop.

Other reviews have found the evidence for cognitive benefits more mixed.

So I can’t tell you that taking 5 g of creatine will suddenly transform your brain after a terrible night’s sleep.

I can tell you that I notice a difference.

And that makes the emerging research particularly interesting to me.

Does Creatine Make You Look Younger?

Now we reach the claim that really caught my beauty-blogging attention.

Creatine can plump ageing skin.

I can understand where the idea comes from.

Creatine increases water within muscle cells. When I take it, I personally feel that my face looks slightly fuller and, to my eye, younger.

But can I prove that creatine has filled out my wrinkles?

No.

And neither, at the moment, can the beauty industry’s marketing.

There is interesting research involving topical creatine.

Studies of skincare formulations containing creatine have reported improvements in things such as skin firmness, wrinkles and sagging.

That’s fascinating.

But applying a creatine-containing formulation directly to the skin isn’t the same thing as swallowing 5 g of creatine powder.

At present, I haven’t found convincing clinical evidence showing that oral creatine supplementation specifically plumps facial wrinkles or makes an ageing face look younger.

So if you’re buying creatine purely because somebody on YouTube promised it would fill your marionette lines, I’d keep your credit card in your purse.

If your face happens to look a little fuller while you’re taking it?

Enjoy it.

Mine seems to.

But that’s an observation, not a proven anti-ageing treatment.

And Yes, the Scales Might Move

This catches people out.

You start taking a supplement associated with fitness and then discover you’ve gained weight.

Brilliant.

But creatine isn’t fat.

Particularly when supplementation begins, additional water is drawn into muscle cells and body weight can increase.

That isn’t the same thing as gaining body fat.

Equally, I wouldn’t describe creatine as a weight-loss supplement.

That’s another claim I came across while researching this article, and the evidence isn’t strong enough for me to put it in that category.

Its much more convincing role is in supporting training, strength and lean tissue.

What About Bloating?

This is one I’ve personally experienced.

Creatine can sometimes leave me feeling bloated.

Not everybody experiences gastrointestinal problems, and dose and how you take it can make a difference.

This is another reason I’m not particularly attracted to enormous loading doses.

Which brings us neatly to…

Do You Need to “Load” Creatine?

If you’ve researched creatine online, you’ll probably have encountered the loading phase.

A traditional approach is around 20 g per day, divided into several smaller doses, for approximately five to seven days before dropping down to a maintenance dose.

Do you need to do that?

No.

Loading gets creatine into the muscles more quickly.

Taking a smaller daily amount — commonly around 3–5 g per day — can also increase muscle creatine stores; it simply takes longer.

Unless there’s a particular reason you want rapid saturation, there’s no requirement to spend a week consuming 20 g of creatine every day.

For someone like me interested in healthy ageing rather than preparing for an Olympic weightlifting competition, slow and steady seems perfectly adequate.

The Kidney Question

And now we arrive at the scary bit.

Does creatine damage your kidneys?

This warning has followed creatine around for years.

The reassuring answer for healthy people is that current research doesn’t show that recommended doses of creatine monohydrate damage healthy kidneys.

But there’s an interesting complication.

Creatine can increase the amount of creatinine measured in your blood.

Creatinine is also one of the markers routinely used to estimate kidney function.

So someone taking creatine can potentially see their blood creatinine rise — and therefore see a creatinine-based estimate of kidney function change — without their kidneys actually having been damaged.

Recent systematic reviews have found this distinction important. More direct assessments of kidney function haven’t shown the same evidence of impairment.

That doesn’t mean everybody should start taking it without thinking.

If you have known kidney disease, abnormal kidney results, take medication affecting kidney function or have another relevant medical condition, this is firmly in the category of:

Talk to your doctor first.

And if you’re having kidney blood tests, I’d also make sure the clinician knows you’re taking creatine.

What Exactly Is in That White Powder?

There’s another side of supplements that interests me increasingly as My Future Face moves into healthy ageing.

Quality.

Creatine monohydrate itself is remarkably well researched.

But a tub labelled “creatine” is still a manufactured supplement.

And supplements don’t all come with identical quality controls.

Rather than assuming that an expensive brand must be better, I’d look for something much more boring:

Creatine monohydrate.

Ideally with very few additional ingredients and from a reputable manufacturer that uses credible independent quality testing or certification.

There are premium brands I personally trust more than an anonymous bargain tub — but I’m increasingly wary of the word “clean”, because it’s another marketing term that can mean almost anything.

I want to know what’s actually in the tub.

Because once again, the back of the packet tells us considerably more than the beautiful branding on the front.

So, Is Creatine Worth Taking After 40?

This is one supplement where I came away from the research more impressed than I expected.

Not because it’s a miracle beauty powder.

It isn’t.

And not because it’s going to melt fat, erase wrinkles, prevent ageing or magically replace exercise.

It won’t.

But there is credible evidence that creatine can support strength and lean mass, particularly when combined with resistance training, and emerging research into its possible effects on the brain and healthy ageing makes it genuinely interesting.

For postmenopausal women in particular, the latest research suggests this isn’t simply a supplement for bodybuilders anymore.

Personally, I’ve noticed better energy and concentration when I use it, particularly when I haven’t slept well.

I’ve also noticed that my face appears slightly fuller.

Those are my experiences, not promises of what it will do for somebody else.

And yes, I’ve experienced some bloating too.

So will creatine stay in my healthy-ageing cupboard?

Probably.

But for a very different reason from the one that first attracted me.

I went looking for a powder that might make my ageing face look a little plumper.

What I found was something potentially much more useful:

a supplement that may help me protect the muscle and strength I’ll need to keep using that face — and the rest of me — for a very long time.
