The pattern is remarkably consistent: exhausted through the day, wide awake at night.

Picture the same Tuesday twice.

At 32. Work, the school run, the shopping, someone who needs a call at nine. You handle it. You're tired. You sleep.

At 41. The exact same Tuesday. Nothing on the list has changed. But by four in the afternoon you're running on fumes. By nine you've snapped at someone you love. And by eleven, finally lying down — your brain switches on and starts listing everything you forgot.

Same day. Same stress. Different body.

Most women look at that and decide the difference is them.

For many women this shift is real. It doesn't mean you've become weak, or that you're failing at something.

If you've mentioned any of this, you've probably been told it's stress. Or that you're doing too much. Or that this is simply what your forties feel like.

So you tried to fix it the way you fix everything else. With discipline.

Magnesium. No screens after nine. A meditation app you used for eleven days. Less coffee, then more coffee, because you needed it to function.

And when none of it worked, you drew the obvious conclusion: the problem was you. You'd become someone who just couldn't cope as well anymore.

The statistic that explains a lot

Flo Health and researchers at the Mayo Clinic's Center for Women's Health surveyed 7,640 American women aged 35 and over. The results were published in Menopause, the journal of The Menopause Society.

One in three women weren't sure what reproductive stage they were even in. And the uncertainty peaked exactly where you'd least expect it.

Why the confusion? Among the women who weren't sure, the most common reason by far — 56% — was symptom confusion. Their periods were still regular, so they assumed hormonal change couldn't be the explanation.¹

Perimenopause is the hormonal transition before menopause. It can begin in the mid-30s and often runs for years. And in a separate Flo and Mayo Clinic study of more than 17,000 women across 158 countries, the symptoms reported most often during it were not the ones you'd expect. Not hot flashes. Fatigue. Mental and physical exhaustion. Irritability.²

Which sound, to almost everyone including doctors, exactly like stress.

And it doesn't stop when the transition does. The estrogen drop is permanent — which is why plenty of women describe the same tired-but-wired pattern well into their fifties, long after their periods ended.

The "stress hangover": why your stress response changed

Here's the part that reframes everything.

When something stresses you, your brain signals your adrenal glands to release cortisol. When the stress passes, the same system switches the cortisol back off. Scientists call it the HPA axis. Think of it as an accelerator and a brake.

When that brake works slowly, cortisol doesn't peak and drop away — it can stay elevated long after the stressful moment has passed. It's the closest thing there is to a stress hangover: the thing that upset you is over, but your body hasn't caught up yet.

Estrogen appears to help work that brake.

Researchers at USC tested this directly. They took postmenopausal women who had been on estradiol therapy for around five years and compared them with women on placebo. Then they put both groups through a physical stressor and measured what happened.

The women on estrogen had a smaller cortisol rise. And unlike the placebo group, their working memory didn't drop afterwards.³

Worth being precise about what that shows. It studied postmenopausal women already on estrogen therapy — not women in their thirties. It points at a mechanism. It doesn't prove what's happening in any individual woman's body.

But as estrogen starts fluctuating and falling — which can begin in the mid-30s — that brake may work less well. For some women, the same amount of stress can mean a bigger response, a slower recovery, and more of that hangover feeling afterwards.

At the same time, something else is happening. As the transition goes on, ovulation becomes less regular. And progesterone is only made after ovulation. So progesterone falls.⁴

That matters because progesterone plays a role in how settled you feel. It's the hormone most associated with restful sleep, and less of it can mean lighter, more broken nights.⁴

And poor sleep raises your stress load. Which raises cortisol. Which makes sleep worse.

This may be why the standard advice can feel like it isn't enough. Sleep hygiene works on your behavior at bedtime. Meditation is genuinely valuable. Both can help — but if there's a physiological component underneath, you're asking them to carry the whole load on their own.

You weren't failing at coping. You may just have been treating one part of a bigger picture.

What "working" actually looks like

Ask women who feel like themselves again what changed, and almost nobody says "my cortisol is lower."

They say the 3am wake-up stopped. They say they got to the end of a long day and still had something left. They say their kid spilled something and they just... wiped it up.

Not a different life. The same life, at the old cost.

What the research points toward

So two things are happening at once: a stress response that's harder to switch off, and a hormonal shift underneath it.

So we went looking for something built around both.

That brings us to a plant people have used for about three thousand years, and that scientists have studied seriously for the last twenty.

The cortisol side

Ashwagandha (Withania somnifera) has been used in Ayurvedic medicine for centuries as a daily tonic. Most modern research on it has focused on stress.

The strongest evidence isn't one study. It's what happens when you pool many. In 2022, researchers combined 12 randomized controlled trials covering 1,002 people aged 25 to 48. Ashwagandha was associated with significantly lower stress and anxiety scores than placebo. The researchers noted that the strongest effects on stress clustered around 300–600mg a day.⁵

In the single most-cited trial — 60 days, randomized, double-blind, placebo-controlled — participants taking a standardized root extract showed an average 27.9% drop in serum cortisol from baseline. The placebo group dropped 7.9%.⁶

That trial used KSM-66®, at 600mg a day. Remember that. It matters later.

On sleep specifically, a 2021 review pooled five randomized controlled trials. Ashwagandha extract had a small but statistically significant effect on overall sleep quality — and the effect was most prominent at 600mg a day, taken for eight weeks or more.⁷

The hormonal side

The research doesn't stop at stress, though.

Two randomized, placebo-controlled trials have looked at ashwagandha root extract in women going through the hormonal transition. The first followed 100 women in perimenopause for eight weeks and found significant improvement in standard menopause symptom scores versus placebo.⁸ The second, published this year, followed 60 women aged 45–55 for eight weeks and found the same — plus a significant drop in perceived stress scores. That trial used KSM-66® specifically.⁹

Separately, a 24-week trial in 123 women compared ashwagandha and shatavari — alone and in combination — against placebo. Both botanicals reduced menopause-related quality-of-life scores, and they did it dose-dependently.¹⁰

Different research teams. Different countries. Same direction of result. That's the kind of repetition that makes a finding worth paying attention to.

Alongside ashwagandha and shatavari, one more botanical shows up constantly in this context: maca root, a traditional adaptogen long associated with energy and hormonal balance in women.

Ashwagandha has been used in Ayurvedic practice for more than three thousand years. Rigorous clinical study of it is far more recent.

Why two ashwagandha products can feel completely different

Here's a frustration a lot of women describe: they tried ashwagandha, felt nothing, and concluded it doesn't work.

Usually the problem isn't the plant. It's what was in the bottle.

The trials above used a standardized root extract, at a specific dose, for a specific length of time. Plenty of products on the shelf specify none of those things. And because "ashwagandha" on a label can mean almost anything, two products can look identical and deliver completely different amounts of active compound.

So here's a test you can run on any bottle, including ours. Turn it over and check four things:

If a bottle can't answer all four, you have no way of knowing what you actually took. Which makes "it didn't work for me" an impossible conclusion to draw.

Who this isn't for

Steady is the wrong product for you if you want to feel something tonight. It won't knock you out, and it isn't designed to.

Talk to a doctor or pharmacist before starting Steady if any of these apply to you:

Have that conversation first — it costs you nothing and it's the right order to do things in.

Ashwagandha has also been associated with rare cases of liver injury. Stop taking it and speak to a doctor if you notice unusual fatigue, abdominal pain, dark urine, or yellowing of the skin or eyes.

And if what you're describing is severe, sudden, or frightening, this is a doctor's question, not a supplement's. Please treat it that way.

An honest word about what to expect

Steady is not a sedative and it is not a quick fix. Anyone selling you an overnight transformation in this category is selling you something else.

The trials that produced the results above ran six to twelve weeks of consistent daily use. That's the timeframe this works on.

What some women report, alongside the windows the research measured. Individual results vary — this isn't a promise of what you'll experience.

That gradual build isn't a weakness of the approach. It's what supporting a system looks like, rather than overriding it.

It does have one practical consequence, though. The clock only starts when you start. Every week of "I'll sort this out later" is a week added to the eight.

Questions people ask before ordering

You're not imagining it

Maybe the most useful thing on this page isn't a product at all. It's the reframe.

If stress you used to absorb now knocks you sideways, that is not a character flaw and it is not a sign you've become fragile. There are documented physiological reasons this can change for women in this window of life. The fact that almost nobody explains it is a failure of information — not a failure of yours.

Understanding the pattern is the first step. Deciding what to do about it is the second.
