Introduction
If you have spent any time researching what to take in perimenopause, you have probably encountered an overwhelming and contradictory landscape. Every wellness influencer has a stack to recommend. Every brand has a perimenopause-specific formula. The supplement aisle is bigger than ever. And the marketing promises range from genuinely evidence-based to completely unfounded.
It is genuinely difficult to know what is worth your time, your money, and your trust.
This article is a clear, honest assessment of what the clinical evidence actually shows - written from a position of clinical practice rather than supplement marketing.
But before getting into specifics, here is the position this article takes openly: supplements are a supporting layer. They are not the foundation of perimenopausal health, and they are not where the most meaningful transformation happens.
The most powerful interventions in this transition are nutritional, lifestyle-based, and where appropriate, clinical. Targeted supplementation can support those interventions - and in some specific situations, supplementation directly addresses deficiencies that are meaningfully affecting how you feel. But supplements work best when the underlying foundation is in place, not as a substitute for it.
Keep that framing in mind as you read. The goal here is informed clarity, not a stack to add to your cart.
Where the Real Work Happens
Before exploring what supplements may help, it is worth being direct about what produces the largest, most consistent, and most durable improvements in perimenopausal health.
It is not supplements.
The interventions that consistently produce the most meaningful clinical results across the perimenopausal transition are:
A structured, personalised dietary approach. Adequate protein, blood sugar stabilising meal structure, anti-inflammatory food choices, gut microbiome support, and adequate intake of the specific nutrients that support hormonal and metabolic health - all calibrated to your individual physiology. This is the work that addresses insulin resistance, reduces inflammation, supports body composition, improves cognitive function, and reduces vasomotor symptoms. It is also the work where personalised, blood-chemistry-based nutritional protocols like Metabolic Balance® produce results that generic dietary advice consistently does not.
Adequate, restorative sleep. No supplement matches what consistent good sleep does for cortisol regulation, insulin sensitivity, cognitive function, and overall metabolic health.
Appropriate movement. Resistance training and daily walking produce metabolic and hormonal benefits that no supplement protocol can replicate. The bone density work alone in this decade is non-negotiable, and only mechanical loading provides it.
Cortisol regulation. Through breath work, time outdoors, restorative movement, and structured rest. The wired-but-tired pattern that drives so many perimenopausal symptoms responds to genuine HPA axis support, not to adaptogens taken alongside chronic stress.
Clinical support where appropriate. HRT for women with significant symptoms; clinical investigation of thyroid, gut health, and other contributing factors; personalised nutritional intervention for women who want results calibrated to their individual biochemistry.
If you are looking for the highest-leverage place to invest your effort, energy, and money in perimenopause, this is it - not the supplement aisle.
That said, targeted supplementation has a legitimate role in supporting this work. Here is the honest assessment.
Insight
The reason most women feel underwhelmed by their perimenopause supplement stack is that they are trying to use supplements to do work that supplementation cannot do alone. A magnesium tablet cannot substitute for a properly structured diet. A B complex does not replace addressing insulin resistance. Adaptogens do not undo the cortisol load of an unsupported life. Supplements work - but they work best as a supporting layer on top of foundations that are already in place. Reverse this priority order, and the disappointment is predictable.
What Comprehensive Testing Reveals
Before considering supplementation, the most clinically useful step is understanding your current nutritional and metabolic status through proper testing. Many women in perimenopause have deficiencies or sub-optimal levels of specific nutrients that are meaningfully affecting how they feel - and correcting those identified gaps is far more impactful than guessing with a generic supplement stack.
The most clinically useful blood tests to consider in perimenopause:
- Vitamin D (25-OH) - deficiency is highly prevalent and affects everything from mood to bone health to insulin sensitivity
- Ferritin - iron stores; commonly low in perimenopausal women due to heavy bleeding patterns
- B12 and folate - deficiency produces fatigue, cognitive symptoms, and mood changes that overlap closely with perimenopausal symptoms
- Full thyroid panel - thyroid dysfunction peaks in onset in this decade and produces symptoms that mimic perimenopause
- Fasting insulin - the most useful marker for insulin resistance, frequently missed in standard panels
- High-sensitivity CRP (hs-CRP) - measures the chronic inflammation that drives so much of the perimenopausal symptom picture
- Magnesium - frequently depleted in women with insulin resistance and chronic stress
- Fasting lipid panel - provides important information about metabolic status and cardiovascular risk
This is the testing that actually informs intelligent supplementation - replacing what is genuinely depleted, supporting what is genuinely affected, rather than adding supplements speculatively. It is also the testing that informs personalised nutritional protocols, which is why we use it as the foundation of Metabolic Balance.
Tier One - Genuinely Worth Considering
These are the supplements with the strongest evidence base, the clearest mechanisms, and the most relevance to the perimenopausal picture.
Vitamin D
Vitamin D deficiency is so prevalent in women in perimenopause that some studies report rates above 70%. Vitamin D is not really a vitamin - it functions more like a hormone, with receptors throughout the body affecting bone health, immune function, insulin sensitivity, mood, and the inflammatory environment.
The case for vitamin D supplementation is straightforward when testing confirms deficiency or insufficiency. Correcting it produces measurable benefits across multiple systems.
The case against speculative supplementation: vitamin D at high doses without testing can produce its own problems. This is one of the supplements where testing before supplementing matters most.
The food-first context: oily fish, eggs, sun-exposed mushrooms, and direct skin exposure to sunlight (when seasonally available) all contribute, though dietary sources alone rarely correct established deficiency in temperate climates.
Omega-3 Fatty Acids (EPA and DHA)
Among the most consistently evidence-backed nutrients available for perimenopausal health - with measurable effects on inflammation, cardiovascular health, mood, cognitive function, and modest vasomotor symptom benefit.
The case for omega-3 supplementation: most women in perimenopause do not consume enough oily fish to reach the levels at which clinical effects on inflammation become significant. For women who do not eat fish regularly, supplementation closes the gap.
The food-first context: oily fish two to three times per week - salmon, sardines, mackerel, anchovies, herring - provides the most bioavailable form of EPA and DHA. Walnuts, flaxseed, and chia seeds provide plant-based omega-3s (ALA), which the body converts to EPA and DHA, though the conversion is limited.
For most women, prioritising regular oily fish intake and supplementing only when dietary intake is genuinely insufficient is the most sensible approach.
Magnesium
Magnesium is involved in hundreds of enzymatic processes, including those governing sleep, muscle function, blood sugar regulation, and nervous system activity. Deficiency is common in women with insulin resistance, chronic stress, and disrupted sleep - all features of perimenopause.
The forms most relevant clinically are magnesium glycinate or bisglycinate (best absorbed and gentle on digestion) and magnesium L-threonate (specifically formulated to cross the blood-brain barrier for cognitive support). Magnesium oxide - the cheapest and most common form - has poor bioavailability and is largely wasted.
The food-first context: dark leafy greens, nuts and seeds (particularly pumpkin seeds, almonds, and cashews), legumes, dark chocolate, wholegrains, and avocado all provide magnesium. Most women whose diet includes generous amounts of these foods meet their magnesium needs without supplementation. Where the diet is more limited or the stress and sleep picture is significant, supplementation can be genuinely useful.
Before adding supplements speculatively, audit what is currently in your diet. Are you eating oily fish two to three times per week? Are leafy greens, nuts, and seeds appearing daily? Are fermented foods part of your routine? Is the protein at every meal? Often the supplement question becomes much smaller once the food question is properly answered.
Tier Two - Useful in Specific Contexts
These supplements have meaningful evidence but are most appropriate in specific situations rather than as universal recommendations.
Iron (If Ferritin Is Low)
Heavy and irregular bleeding through perimenopause can produce significant iron loss, and low ferritin contributes meaningfully to fatigue, hair thinning, cognitive symptoms, and reduced exercise capacity.
The case for iron supplementation is straightforward when ferritin testing confirms low stores - and the optimal target for energy and hair is typically higher than the standard laboratory lower limit. The case against speculative supplementation: iron excess is harmful and supplementing without confirmed need is counterproductive. Iron is one supplement where testing first is essential.
The food-first context: red meat, oysters and other shellfish, liver, dark poultry meat (haem iron - most bioavailable), and legumes, dark leafy greens, pumpkin seeds, and tofu (non-haem iron - less bioavailable but still useful). Vitamin C with iron-containing meals improves absorption; tea and coffee at meals reduces it.
B Vitamins (Particularly B12 and Folate)
B12 deficiency is increasingly common in midlife and produces symptoms that closely mimic perimenopause - fatigue, cognitive changes, mood disturbance. Testing identifies whether supplementation is warranted; speculative supplementation without testing is rarely the right starting point.
For women following plant-based or low-meat diets, B12 supplementation is appropriate even without testing, as dietary B12 intake from plant sources is essentially nil.
The food-first context: B12 is found primarily in animal foods - meat, fish, eggs, dairy. Folate is found in dark leafy greens, legumes, liver, and asparagus.
Phytoestrogens - Through Food, Not Supplements
Phytoestrogens have moderate evidence for reducing vasomotor symptoms in women who consume them regularly. The strongest evidence is for whole soy foods and ground flaxseed consumed as part of the regular diet.
This is one area where the evidence supports the food form rather than the supplement form. Whole soy foods - tofu, tempeh, edamame, miso - and ground flaxseed produce the modest vasomotor benefits seen in research; isolated soy isoflavone supplements produce more variable results and miss the broader nutritional benefits of the whole foods.
For women interested in the phytoestrogen approach, building these foods into the regular diet is more useful than purchasing isoflavone supplements.
Probiotics (Strain-Specific)
The gut microbiome's role in perimenopausal health is increasingly well-documented - and targeted probiotic strains can support insulin sensitivity, mood, and inflammatory regulation. Strain specificity matters enormously; generic "probiotic" supplements vary wildly in quality and relevance.
The food-first context - this is the most important point: fermented foods consistently produce more meaningful microbiome benefits than supplement-form probiotics for most women. Natural yoghurt with live cultures, kefir, kimchi, sauerkraut, and miso provide both diverse bacterial strains and the food matrix that supports their survival and integration. Regular fermented food intake is the most evidence-backed gut microbiome intervention available.
Probiotic supplementation has a place where specific clinical needs apply - but for general gut microbiome support in perimenopause, fermented foods generally outperform supplementation.
Tier Three - Emerging or Specific-Use
These supplements have plausible mechanisms and accumulating evidence but are less universally applicable.
Creatine Monohydrate
Long known as a muscle supplement, creatine has rapidly accumulating evidence for cognitive support, bone density, and muscle function in midlife women specifically. The mechanism involves cellular energy production, which is relevant to both muscle and brain function.
This is one of the more interesting emerging areas in perimenopausal supplementation, with the evidence strengthening meaningfully in recent years. Worth being aware of and discussing with a clinician familiar with the current research.
Curcumin
The active anti-inflammatory compound in turmeric, with consistent evidence for reducing inflammatory markers and joint pain. Particularly useful for women with prominent joint symptoms or chronically elevated inflammatory markers. Combined with piperine (black pepper extract) for bioavailability.
The food-first context: turmeric used regularly in cooking, alongside black pepper and a fat source, provides modest curcumin intake. Therapeutic doses for clinical effect typically require concentrated supplementation.
Ashwagandha
Adaptogenic herb with consistent clinical evidence for reducing cortisol and supporting the HPA axis. Useful particularly for the more reactive cortisol environment of perimenopause and for women with prominent anxiety, sleep difficulty, or chronic stress symptoms.
Black Cohosh
One of the most studied herbal interventions for hot flushes specifically, with moderate evidence for benefit in some women. Effects are variable between individuals. Worth a trial under clinical guidance if vasomotor symptoms are significant and other approaches have been insufficient. Best used short-term rather than indefinitely.
What to Be Sceptical About
A few things commonly marketed for perimenopause that do not have strong evidence to support their wide promotion:
Generic "perimenopause formula" blends - proprietary multi-ingredient products that combine multiple herbs and nutrients at undisclosed or sub-therapeutic amounts. The individual ingredients may have some evidence; the specific combinations in these products typically do not. You also cannot verify what you are getting at what amount.
Adrenal fatigue protocols - adrenal fatigue is not a recognised medical condition, despite widespread marketing. HPA axis dysregulation is real and clinically important, but the high-dose adrenal glandular and herbal protocols marketed for it are largely unsupported by clinical evidence.
Collagen specifically for menopausal symptoms - collagen supports skin and connective tissue at higher doses, but it does not specifically address perimenopausal symptoms or hormonal balance. The skin benefits are modest and well-documented; the broader claims often made are overstated.
Wild yam creams for "natural progesterone" - wild yam contains diosgenin, which can be converted to progesterone in a laboratory but is not converted by the body. Topical wild yam creams marketed as natural progesterone replacement do not deliver progesterone. Body-identical progesterone, where clinically appropriate, requires prescription.
Mega-dose multivitamins - the "more is better" approach to vitamins typically produces no additional benefit and can produce harm with fat-soluble vitamins. A modest, evidence-based approach is consistently more useful than high-dose formulations.
The most useful question to ask about any supplement: what is the specific clinical evidence for this nutrient, at this dose, in this context? If that question cannot be answered clearly - including by you, after researching - the product likely does not belong in your protocol. The supplement industry depends on women buying products that have never been adequately tested or specifically formulated for the situations they claim to address.
The Honest Order of Operations
If a woman in perimenopause asks me where to start, this is the honest order of operations - and it is rarely the order that supplement marketing suggests:
First - get the food right. Adequate protein at every meal, blood sugar stabilising structure, anti-inflammatory foundation, gut microbiome support through fermented foods and plant diversity, adequate intake of the foods that provide the nutrients perimenopause demands. This is where the largest and most durable benefits come from.
Second - get the rest of the foundation right. Sleep, movement (particularly resistance training), cortisol regulation, time outdoors. These factors compound the benefits of nutritional work and produce results no supplement matches.
Third - get tested. A comprehensive blood panel reveals what is actually deficient or sub-optimal versus what you are assuming. This guides intelligent supplementation rather than speculative supplementation.
Fourth - supplement where genuinely indicated. Replace what is confirmed depleted. Support what the foundation alone cannot fully address. Use the evidence base, not the marketing.
Fifth - consider clinical support where appropriate. Personalised nutritional intervention for women who want results calibrated to their individual biochemistry. HRT where vasomotor symptoms or other concerns warrant the conversation. Other clinical investigation where indicated.
This order matters because it represents where the actual returns come from. Reverse it - start with supplements, hope they do the work the foundation should be doing - and the disappointment is predictable.
Clinical Insight
The evidence base for nutritional management of perimenopausal health is now substantial - and it consistently identifies food-based intervention, not supplementation, as the most impactful single lever available. Specific dietary patterns supporting blood sugar stability, anti-inflammatory profile, and adequate protein and micronutrient intake produce measurable improvements in metabolic markers, vasomotor symptoms, cognitive function, and overall symptom burden. Supplementation has a legitimate supporting role - particularly for correcting identified deficiencies (vitamin D, B12, iron, magnesium) and supplementing genuinely insufficient dietary intake (omega-3s) - but is rarely a substitute for foundational nutritional work. The clinical reality, supported consistently in research and practice, is that personalised nutritional intervention calibrated to individual biochemistry produces the most significant and durable improvements in perimenopausal health. Generic supplement protocols, by contrast, produce disappointingly variable results because they cannot address the foundational nutritional environment in which the supplements operate. For women seeking meaningful transformation through this transition, the work of getting the food right - properly, comprehensively, and ideally personally - is where the largest returns are found.
The Bottom Line
Supplements have a place in perimenopausal health - but a more modest place than the supplement industry suggests.
The foundational work - structured, ideally personalised nutrition, alongside sleep, movement, cortisol regulation, and where appropriate clinical support - is where the most meaningful transformation happens. This is the work that addresses insulin resistance, reduces inflammation, supports body composition, regulates cortisol, improves sleep and cognitive function, and reduces vasomotor symptoms. It is also the work that no supplement protocol replaces.
Targeted supplementation supports this work. Correcting deficiencies confirmed by testing. Adequate omega-3 intake where dietary fish is limited. Magnesium where stress and sleep demand more than the diet can provide. Vitamin D in temperate climates. A few additions chosen carefully based on individual context.
This is a much smaller, more honest list than the supplement aisle promises. It is also a much more effective approach in practice.
If you take one thing from this article: invest in the food first. The supplements work better when you do.

Ready to Address the Foundation Properly - With a Plan Built for Your Individual Body?
Generic supplement stacks are popular because they are easy. They are also rarely transformative.
The most significant results in perimenopausal health come from getting the foundation right - and getting it right specifically for your individual biochemistry, not for women in general. My metabolic health programs use your blood test results to design a nutrition protocol calibrated specifically to your metabolism, your hormonal picture, and your individual nutritional needs.
This is the work that consistently produces the clinical outcomes we see - measurable improvements in inflammatory markers, insulin sensitivity, body composition, energy, sleep, mood, and the broader perimenopausal symptom picture. Not because of any single intervention, but because the whole foundation is finally working together.
