Ashwagandha, Rhodiola & Maca for Perimenopause: What They Actually Do (and Who Should Skip Them)

You've probably seen adaptogens everywhere lately. Ashwagandha gummies at the checkout. Rhodiola in your favourite influencer's morning routine. Maca powder in every wellness smoothie on Instagram. And honestly? If you're in perimenopause and you're exhausted, anxious, not sleeping, and running on fumes — the promise of a plant that “balances your hormones” sounds like exactly what you need. Right?

Here's the thing. These herbs can genuinely help. For some women, they're a real turning point. But the way adaptogens are being marketed right now — as universally safe, take-as-much-as-you-like superfoods — is leaving out some really important information. Information that matters especially if you've got a thyroid condition, a history of hormone-sensitive cancers, or you're already on medication.

So let's slow down. Let's talk about what ashwagandha, rhodiola, and maca actually do in your body, who they're genuinely suited for, and who needs to be careful — or skip them altogether. No hype. Just honest, practical information so you can make a real decision.

Why Adaptogens Feel So Relevant in Perimenopause

Perimenopause isn't just about hot flushes. For a lot of women, the earliest signs are being blindsided by anxiety they've never had before, sleep that used to be fine suddenly falling apart, and a bone-deep fatigue that no amount of rest seems to fix. You go to the doctor. Labs are fine. “Everything looks normal.” And you walk out feeling like you imagined it all.

You didn't imagine it. What's actually happening is a cortisol story as much as an oestrogen one. As oestrogen starts declining — and it doesn't decline in a smooth, predictable line, it fluctuates wildly — your HPA axis (the stress-response system that governs cortisol) becomes increasingly dysregulated. Your nervous system is working harder. Your sleep architecture changes. Your resilience to stress drops. You're not going down the well because something is wrong with you. You're going down the well because your body's hormonal scaffolding is shifting, and that affects everything.

Adaptogens work on that stress-response system. That's the connection. That's why they're relevant. Understanding what's actually happening in perimenopause helps you see why some of these herbs can genuinely support how you're feeling — and why they're not a fix for the underlying hormonal shifts themselves.

Ashwagandha: The Calming One

Ashwagandha (Withania somnifera) is what most people reach for first, and with good reason. It's the most researched adaptogen we have for stress and sleep. It works primarily by modulating the HPA axis — turning down that constant fight-or-flight activation that leaves you wired and exhausted at the same time. If you're lying awake at 3am with your heart racing and your brain spiralling over nothing, elevated cortisol at night is often part of what's driving that.

Clinical trials in perimenopausal women have shown meaningful improvements in anxiety, sleep quality, and quality of life markers. It's a genuinely calming adaptogen — not sedating, but settling. Think of it as turning the volume down on your nervous system rather than switching it off.

Best taken: Evening, to support nighttime cortisol calming. Some women do well with a morning dose too, but if you're sensitive, start in the evening.

Now here's where I need you to pay attention. Ashwagandha is contraindicated — meaning you should not take it without medical supervision — in several situations:

• Thyroid conditions. Ashwagandha can increase thyroid hormone levels. If you have Hashimoto's, hypothyroidism on medication, or hyperthyroidism, this matters enormously. It can push your levels in unpredictable directions and interfere with your medication. Your doctor needs to know, and your levels need monitoring.
• Autoimmune conditions. Because ashwagandha can stimulate immune activity, it may exacerbate autoimmune conditions. This includes lupus, rheumatoid arthritis, and yes, Hashimoto's again — which is autoimmune in nature.
• Pregnancy. Contraindicated. It has traditionally been used to induce labour. Do not use it if there's any chance you could be pregnant.
• Hormone-sensitive cancers. There's theoretical concern about its mild hormone-modulating effects. If you have or have had a hormone-sensitive cancer (breast, ovarian, uterine), speak to your oncologist before using it.
• Sedative medications. It can potentiate sedatives, including benzodiazepines and some sleep medications.

I'm not saying this to scare you away from it. I'm saying it because I'm angry on your behalf that this information isn't on the front of the packet.

Rhodiola: The Energising One

Rhodiola rosea works differently from ashwagandha. Where ashwagandha is calming, rhodiola is activating — it supports your body's resilience to stress by influencing serotonin, dopamine, and norepinephrine. It's particularly helpful for that foggy, flat, can't-get-going exhaustion — the kind where you've had eight hours of sleep and you still feel like you haven't moved.

For perimenopausal women dealing with fatigue, cognitive fog, and low mood, rhodiola can feel like someone turned the lights back on. It has a mild stimulating effect, which is why timing matters. Taken too late in the day, it can make sleep worse — the opposite of what you need.

Best taken: Morning, or early afternoon at the latest. Not in the evening.

Who should be careful:

• If you're already anxious or have a history of bipolar disorder, rhodiola's activating effect can tip into agitation or trigger elevated mood states. Some women feel great on it; others feel jittery and wired. Start low, go slow, and pay attention to how you feel in the first week.
• If you're on antidepressants or SSRIs, there's a theoretical risk of serotonin syndrome given rhodiola's activity on serotonin pathways. This one needs a conversation with your prescriber — not a Google search and a hope for the best.
• Autoimmune conditions warrant the same caution as with ashwagandha.
• Pregnancy: Avoid.

The women rhodiola tends to suit best are those with fatigue-dominant symptoms, flat mood rather than anxious mood, and no thyroid or autoimmune complications. That's a real group of women in perimenopause. But it's not everyone.

Maca: The Hormonal Ally

Maca (Lepidium meyenii) is technically not an adaptogen in the strictest botanical sense — it doesn't act directly on the HPA axis the way rhodiola and ashwagandha do. But it's consistently grouped with them, and for perimenopause specifically, there's a decent body of research behind it.

Maca appears to support hormonal balance by acting on the hypothalamus and pituitary — essentially influencing the signalling that tells your ovaries what to do, rather than directly supplying hormones. This is why it's described as hormone-modulating rather than hormone-containing. Studies in perimenopausal women have shown improvements in oestrogen levels, hot flush frequency, mood, and sexual function.

It's also genuinely energising without the stimulant edge of rhodiola. More of a steady, calm vitality — which makes it a nice daytime ally for women who feel depleted but don't want anything that might spike anxiety.

Best taken: Morning or with food during the day. Gelatinised maca is much easier on the digestive system than raw maca powder, worth knowing if you've tried it before and felt nauseous.

Who needs to be careful:

• Thyroid conditions — particularly hypothyroidism. Maca is a cruciferous vegetable. Like broccoli and kale, it contains goitrogens — compounds that can interfere with thyroid hormone production when consumed in large amounts. For most people with healthy thyroid function, this isn't a meaningful concern. But if your thyroid is already masked or struggling, or if your labs are fine but you know something's off, be thoughtful about dose and talk to your doctor. For more on the thyroid-hormone connection, the thyroid hormone health hub covers this in detail.
• Hormone-sensitive conditions. The evidence on maca and oestrogen is nuanced — it appears to work through the hypothalamic-pituitary axis rather than acting as a phytooestrogen, but if you have a hormone-sensitive cancer history, this is another conversation for your oncologist, not your Instagram feed.
• PCOS. Maca's effect on LH and FSH levels means it could potentially affect the hormonal picture in PCOS. Not a hard no, but a proceed with awareness.

The Bigger Picture: Taking Adaptogens Intelligently

Here's what frustrates me about the current wellness conversation around adaptogens. Women are taking these supplements — sometimes several at once, sometimes in high doses, sometimes from companies with no quality control — without knowing that they interact with thyroid medication, that they can shift hormone levels, that they're contraindicated in autoimmune conditions that many perimenopausal women have.

The dismissal we get from doctors — “just take it easy, your labs are fine, it's just stress” — pushes us toward self-managing. And I get it. When you're frozen in the middle of the supermarket because you can't remember why you're there, and your doctor has suggested you might be depressed, you look for solutions wherever you can find them. That's not naivety. That's desperation dressed up as resourcefulness.

But taking a stack of adaptogens without understanding your own picture — your thyroid function, your autoimmune history, your medications, your cancer history — is a real risk. Not a theoretical one.

So. If you want to try adaptogens — and many women will genuinely benefit — here's the practical framework:

• Try one at a time. Not a blend. One herb, so you know what's working and what isn't.
• Give it six to eight weeks before judging it. Adaptogens aren't fast-acting. They build.
• Check your thyroid, autoimmune status, and medication list first.
• Source from reputable brands that third-party test for purity and potency. This matters enormously with herbs.
• Tell your GP or prescribing doctor what you're taking. Every time.

Adaptogens aren't magic. They're not going to replace the work of understanding what's actually happening hormonally in your body. But they can be genuinely useful tools — when you know which one fits your situation, and when you know who they're not for. You deserve that information. All of it.
