Perimenopause
5 things perimenopause takes before it takes your period
Most women can name the hot flashes. Far fewer are told the transition often begins years earlier, and that the first things it takes are the ones nobody thinks to connect to hormones at all.
Disclosure: this article is written for general information and is not medical advice.
The average woman spends somewhere between four and eight years in perimenopause before her periods stop. For many, it begins in the early forties. For some, the late thirties.
And for most of that time, she does not know that is what is happening.
What she knows is that something has shifted. Sleep breaks at the same hour every night. Words go missing mid-sentence. The recovery that used to take a day now takes three. She is shorter with the people she loves than she means to be. She files each of these separately, under stress, or work, or the season she is in, or getting older.
She almost never files them under the same heading. Because nobody told her they belonged together.
What follows is not a list of symptoms. It is a list of losses, in roughly the order women tend to notice them. Some are worth a conversation with a doctor. Some are quieter than that, and more fixable than most women are led to believe.
The hour you used to sleep through
It is rarely trouble falling asleep. It is waking. Two, three in the morning, fully alert, for no reason that daylight would accept as a reason.
Sometimes it comes with heat. Sometimes with a heart going far faster than the situation calls for. Women describe lying still in the dark doing arithmetic on their own pulse, deciding whether this is the night it turns out to be something.
Two things are true here, and both matter. The first is that a racing heart at night is a recognised feature of the perimenopausal transition, and a great many women are told it is stress before anyone says the word perimenopause to them. The second is that palpitations have other causes, some of which need proper attention. Anyone experiencing them should see a doctor and have those ruled out. That is not a formality, and it is not a box to tick on the way to a supplement. It is the responsible order of operations. It also means that when the tests come back clear, the answer is not nothing. It has a different name.
“It’s perimenopause. Nobody tells you it can start this early. I spent two years thinking I had a heart condition before anyone said the word to me.”

The end of your own sentences
The word that will not come. The thought that arrives and leaves before it can be used. The grocery list held confidently in the head all day and then half gone by the time the trolley reaches the till.
This is the loss women are most frightened by and least likely to mention, because the private fear attached to it is not hormonal at all. It is the fear that this is the beginning of something permanent.
Cognitive changes through the transition are well documented, and for most women they are not the start of decline. They are a period of adjustment, in a brain recalibrating to a different hormonal environment while also, very often, running on interrupted sleep.
Which is where the fuel underneath starts to matter. The brain runs on creatine, and women carry lower baseline stores than men. It is one of the most researched supplements in existence, and one of the least associated, in most women’s minds, with themselves.
“Apparently the creatine’s supposed to help with brain fog too. She’s a nurse, even she was surprised by that one.”

The patience you used to have spare
Snapping at someone over something that was not about them. Then the worse part, which is the review afterwards, the private accounting of who you are becoming.
Reactivity through the transition is not a character change. Oestrogen influences the systems regulating mood and the stress response, and when it fluctuates, the buffer between an irritation and a reaction gets thinner. Add broken sleep on top and it is thinner again.
Magnesium and L-theanine both act on pathways involved in that regulation. Neither is a personality transplant. What women describe, consistently, is something smaller and more useful: a little more room between the thing that happens and the way they respond to it.
The body that used to bounce back
The workout that used to cost nothing now lingers for days. Strength that held steady for twenty years starts asking for more to stay where it was.
This is the loss with the longest tail, because muscle and strength in midlife are not a vanity project. They are what independence is built on decades later.
It is also the one with the most direct evidence behind it. In a 2024 study, creatine supplementation significantly improved lower-body strength in peri- and postmenopausal women. Not in twenty-five-year-old men, which is where most supplement research has historically been done. In women, at this stage of life.
“The number one supplement for women is creatine. Women have lower baseline creatine levels than men, which means the supplementation gap is larger and the benefits are more pronounced.”

Whatever was left of you at 9pm
This is the one that gets named last, if it gets named at all.
It shows up as wanting nothing. Not sex, not conversation, not the project that used to matter. Not because anything is wrong with the marriage or the work, but because by nine in the evening there is nothing left in the tank to want with.
Libido is one of the first things to go when a body is triaging its energy, and one of the last things anyone warns women about. It tends to be read as a relationship problem, or a personal failing, or evidence that something fundamental has changed. Usually it is arithmetic. There is only so much fuel, and wanting sits near the bottom of the list of what gets funded.
Which is the part that moves first. Not because a supplement resolves a hormonal transition, but because the reserve underneath it is the piece that responds to being refilled.
“Your body’s triaging whatever energy it’s got left, and wanting sex is the first thing on the chopping block every single time. You’re not broken. You’re just out of fuel.”

Two different problems, and they need two different answers
Perimenopause is a hormonal event. The hot flashes, the night sweats, the cycle changes, the palpitations that need investigating: those belong in a conversation with a doctor who takes them seriously. Hormone therapy helps a great many women, and nothing sold in a sachet is a substitute for that conversation.
But underneath the hormonal event there is a second layer, and it is the one almost nobody addresses. It is depletion. Magnesium that runs short in roughly half of women. Creatine stores that start lower in women than in men and matter more for the brain than most people realise. A stress response running without much buffer left.
That layer is not the transition itself. It is the fuel underneath it. And unlike the hormones, it responds to being topped back up.
This is worth being precise about, because the honest version is less dramatic than the marketing version. Women who take magnesium, creatine and L-theanine nightly do not generally report that their night sweats stopped or their 3am waking ended. What they report is the reserve coming back. Something left at nine in the evening. Finishing sentences. Less edge. The workout that stops costing three days.
Which, if you have spent two years assuming that version of yourself had left permanently, turns out to be the part that mattered most.
Supplements sit alongside medical care, never in place of it
Book an appointment if any of the following apply:
- Heart palpitations, chest pain, breathlessness or fainting. These need cardiac causes ruled out first, regardless of age or what else is going on.
- Very heavy, prolonged or unusually irregular bleeding.
- Low mood or anxiety that is persistent, or that is affecting daily life.
- Symptoms interfering with work, sleep or relationships. Hormone therapy is worth discussing.
- Any new symptom that concerns you, or that a previous clinician dismissed without investigating.
