Creatine — The Cheap, Boring, Extraordinary Supplement Nobody Told Women About

I had creatine sitting in my cupboard for months. I'd ordered it, taken it for a few weeks, noticed nothing obvious, and quietly moved on. It sat there next to the magnesium and the vitamin D, doing nothing, going nowhere. Another supplement that probably wasn't worth the fuss.

Then I listened to the Diary of a CEO.

Dr Stacy Sims was talking about creatine for women — what it actually does, why women need it, why the gym-bro marketing has been one of the most damaging things to happen to women's health in a generation. I sat up straight. Then I went and read every paper I could find. Then I dug the tub back out of the cupboard.

The problem wasn't the creatine. The problem was that I hadn't understood what it was actually doing — and without understanding that, there was nothing to notice yet. Now I take 5g every morning without fail. My brain is sharper. My mood more stable. My energy more sustained. I wish someone had explained this properly the first time.

So let me do that now.

The Moment Everything Changed — Start Here

Creatine has a branding problem. For decades it sat in the supplement aisle next to protein powder, marketed almost exclusively to male athletes trying to build muscle. Most women hear "creatine" and think bodybuilder. Think bulk. Think not for me. Steven Bartlett described exactly this moment on his podcast — talking to his partner about creatine at New Year's, recommending she try it, and her response being an immediate, firm "that's not for women." She thought it was for bodybuilders. She was wrong. So were most of us.

If you want to understand why creatine matters for women, these three episodes are where to start:

What Creatine Actually Is

Creatine is a naturally occurring compound your body makes from three amino acids — glycine, arginine, and methionine. You find it primarily in muscle and brain tissue. You make some yourself, and you get small amounts from red meat and fish. But most women — particularly those eating less meat as they age — are running significantly below optimal levels. Women naturally have lower creatine stores than men, sitting at around 70–80% of male levels, which means we often have more to gain from supplementation.

Here's the mechanism: creatine helps regenerate ATP — adenosine triphosphate — your body's primary energy currency. When you need a burst of energy (lifting something heavy, sprinting, thinking hard under pressure), your body burns through ATP faster than it can make it from scratch. Creatine bridges that gap, donating a phosphate group to regenerate ATP almost instantly.

That's it. One elegant function. And from it flows an extraordinary range of benefits — because almost every cell in your body runs on ATP.

Why Perimenopause Changes Everything

Here is what nobody prepares you for: the years before your final period are when your body starts losing the biological scaffolding it has relied on for decades. Oestrogen — not just a reproductive hormone but a full-body protector — begins its decline. And that decline touches nearly everything creatine happens to support.

Muscle. Oestrogen plays a direct role in muscle protein synthesis. As it declines, you lose muscle mass at an accelerating rate — up to 1% per year after 40, faster still after the final period. Muscle loss is not just aesthetic. It affects your metabolism, bone density, balance, fall risk, and long-term independence. Creatine combined with resistance training is the most evidence-backed intervention available for preserving and building muscle mass in midlife women.

Brain and cognitive function. Creatine crosses into brain tissue. Higher brain creatine levels are associated with better memory, faster processing speed, sharper attention, and reduced mental fatigue. For women wading through brain fog at 3pm, this is not a minor benefit. A 2022 review in Nutrients found creatine significantly improved cognitive performance in females — with effects that were larger than those seen in males.

Mood and emotional stability. A brain with adequate energy regulates mood more effectively. The CONCRET-MENOPA trial (2025, Journal of the American Nutrition Association) — the first randomised controlled trial specifically targeting creatine in perimenopausal and postmenopausal women — found meaningful improvements in mood swing severity and emotional balance after just eight weeks of supplementation. No adverse effects were identified.

Bone density. Oestrogen protects bone. Its decline accelerates bone loss, particularly in the years immediately following the final period. Research suggests creatine combined with resistance training significantly reduces bone resorption markers — the biological process that breaks bone down — compared to exercise alone.

Sleep recovery. Up to 47% of perimenopausal women experience significant sleep disruption. Creatine has been shown to improve cognitive performance specifically in sleep-deprived individuals — and there is now a specific protocol for using it as a morning rescue tool after a bad night. More on that below.

But Won't It Make Me Bulky?

No. And I want to address this head-on because it is the single biggest reason women avoid creatine, and it is based on a misunderstanding that has cost us years of benefit.

Creatine does not make women bulky. What it does is help you hold onto and build lean muscle — which, after 40, becomes increasingly difficult without active support. Lean muscle makes you look stronger and more defined, not bigger. The physiques associated with anabolic supplements are the result of years of extremely high-volume training, specific nutrition protocols, and compounds that are in an entirely different category. Creatine is not in that conversation.

Dr Stacy Sims is direct on this point: women who avoid creatine because of bulk fears are leaving one of their most powerful health tools on the table.

In the first one to two weeks, you may notice a small increase on the scale — typically 0.5–1.5kg. This is water being drawn into your muscle cells, not under your skin. It's a sign the creatine is being absorbed and is working. For most women it levels off quickly, and once the energy and strength benefits kick in, the number on the scale becomes entirely irrelevant.

How to Take It — Dose, Timing, and What I Actually Do

My daily dose: 5g. I stir it into a glass of water every morning. It dissolves almost completely, has essentially no taste, and takes about ten seconds. That's it. No ceremony, no protocol, no special timing. Just 5g every day, consistently, for as long as I can remember why I started.

The evidence-based range: 3–5g daily is the standard recommendation. Dr Stacy Sims recommends 3–5g for ongoing muscle, brain, and bone support. You do not need to do a loading phase — consistent daily use saturates your muscle stores within 3–4 weeks. Cycling on and off is not necessary and not supported by evidence.

Timing: Less important than consistency. Some evidence suggests slightly better uptake when taken with carbohydrates and protein (insulin helps drive creatine into cells), so a morning meal or post-workout shake is sensible. But if you take it in your coffee and forget to think about it, that works too.

Which form: Creatine monohydrate. Not creatine HCL, not buffered creatine, not creatine ethyl ester. Monohydrate has the most research, the best safety record, and is significantly cheaper. Look for Creapure® certification — a German manufacturing standard for pharmaceutical-grade purity. "Micronised" simply means smaller particles that dissolve more easily — a practical convenience with no physiological difference.

The Sleep Strategy — What Stacy Sims Does After a Bad Night

This is the part of the creatine story that most people don't know about yet, and it's extraordinary.

Sleep deprivation depletes brain energy stores. When you don't sleep well, your brain's creatine reserves drop — which is one of the reasons a bad night leaves you cognitively impaired, reactive, foggy, and emotionally dysregulated. The typical perimenopausal response to a terrible night's sleep is coffee, carbs, and a grim determination to get through the day. Dr Sims has a better approach.

Research shows that a single, higher dose of creatine — approximately 0.35g per kilogram of bodyweight — can significantly restore cognitive function after poor sleep. For most women this works out to around 20g taken as a single morning dose. The mechanism is direct: you're flooding your brain with the energy substrate it burned through overnight, giving it the fuel it needs to function.

Dr Stacy Sims uses this protocol herself. On mornings after genuinely poor sleep — not just six hours, but disrupted, broken, sweaty, perimenopausal poor sleep — she takes a higher single dose to protect her cognitive output for the day. The 2024 research published in Frontiers in Nutrition supports this approach across adult populations, and the perimenopause-specific angle is a natural fit given how commonly sleep is disrupted at this life stage.

Does It Work Without Exercise?

Yes — but it works considerably better combined with resistance training. The evidence for muscle, strength, and bone is most powerful when creatine and exercise are paired. Creatine helps you work harder in training; training stimulates muscle protein synthesis; creatine supports the energy for recovery and adaptation. The two are genuinely synergistic.

That said, creatine delivers meaningful benefits for brain function, mood support, and cellular energy regardless of exercise status. If you're not currently lifting weights, creatine is a good reason to consider starting — even two sessions per week produces measurable benefits for muscle, bone, and metabolic health. But don't wait until you're exercising to start the creatine. Do both.

Is It Safe? The Kidney Question

Creatine is one of the most extensively safety-tested supplements in human history. Over 1,000 studies. Decades of clinical trials. The answer is yes — creatine monohydrate is safe for healthy adults at the doses discussed here.

The kidney concern comes from a misunderstanding. Creatine metabolism produces creatinine, a waste product filtered by the kidneys. If you supplement creatine and then have blood tests, your creatinine levels may appear elevated — which can look like a kidney function problem to a GP who doesn't know you're supplementing. It isn't. Mention to your doctor that you take creatine so the result is interpreted correctly.

If you have existing kidney disease, speak to your specialist before starting. For everyone else, the evidence over decades is clear: no risk to kidney function at 3–5g daily in healthy adults.

Can You Take It With HRT?

Yes. Creatine and HRT work through entirely different mechanisms. No interactions have been identified. If anything, they complement each other — HRT addressing the hormonal root of menopausal symptoms, creatine supporting the muscle, brain, and energy systems that benefit from additional cellular fuel.

What VelaOra Recommends

Creatine monohydrate is so well-standardised that brand matters less than quality certification. Here's what I look for:

Questions I Get Asked

How long before I notice a difference? Most women notice improved energy in training within 2–3 weeks. Cognitive benefits tend to emerge around the 4–6 week mark. The sleep-rescue dose effect is more immediate — you should feel it within a few hours. Give the daily dose three months before judging it fully.

Will it interact with my thyroid medication / antidepressants / blood pressure medication? No known interactions have been identified between creatine monohydrate and these medication classes. Always mention new supplements to your prescribing doctor — not because there's a known risk, but because they should have a complete picture.

What about creatine gummies? Skip them. Creatine degrades in acidic or liquid environments — which is exactly what a gummy is — so most deliver far less than labelled. The dose per gummy is also tiny; you'd need 8–12 to hit 5g, at significant cost. They exist because monohydrate powder has a branding problem, not because gummies work better. Stick with micronised monohydrate powder.

It gave me bloating / stomach upset before. This is more common with cheap creatine products or non-micronised powder. Switch to a micronised creatine monohydrate and take it with food rather than on an empty stomach. If symptoms persist, reduce to 3g daily rather than 5g.

Can I take the 20g dose every day? The higher dose is intended as an occasional acute strategy after poor sleep — not a daily practice. Your standard 5g daily is what you're building on. The rescue dose is for the mornings you genuinely need it.

I don't exercise. Is there still a point? Yes, particularly for brain energy support, mood, and the sleep-rescue protocol. You'll leave significant benefits on the table without resistance training, but creatine is not without value as a standalone supplement. And perhaps start with two resistance sessions a week — the combination is where the real magic is.

Women have been marketed to for decades. Expensive powders, beautiful jars, complex formulas with sixteen ingredients and a story about how they were "inspired by ancient wisdom." And meanwhile, one of the most profoundly beneficial things we could take for our muscle, our brain, our bones, and our mood has been sitting in a plain white bag on the bottom shelf at $25 a pop — mostly ignored by the women who need it most.

That's the bit that frustrates me. Not the science — the science is extraordinary and I love it. It's the gap between what's in the research and what women are actually told. That's why VelaOra exists. And that's why I wrote this.

Get the creatine. Take 5g every morning. Add resistance training if you can. And on the mornings after a truly terrible night — reach for the bigger dose, give your brain what it needs, and carry on. You have enough to deal with.
