Tired, Wired or Menopausal? The Supplements Actually Worth Understanding
Updated: Sep 27
THE URBAN EDIT · SUPPLEMENTS, WITHOUT THE FAIRY DUST
Supplements have become the answer to questions nobody has properly asked. Tired? Iron. Wired? Magnesium. Menopausal? Apparently half of Amazon. Scroll Facebook for long enough and a gummy will eventually offer to sort your cortisol, sleep, hormones, focus and possibly your council tax.
The useful approach is less glamorous: start with the symptom, consider what can actually cause it, then decide whether nutrition or supplementation has a sensible role. This article discusses evidence and safety; it does not diagnose deficiency or recommend a supplement as treatment for fatigue, menopause, insomnia, anxiety, hair loss or any other medical condition.

01 · FATIGUE & LOW ENERGY
Fatigue is where supplement marketing becomes particularly slippery. Tiredness can accompany perimenopause, especially when sleep is repeatedly disrupted, but it can also reflect iron deficiency, anaemia, thyroid disease, B12 or folate deficiency, low mood, sleep apnoea, medication effects and a fairly long list of other causes. Treating every exhausted person with a multivitamin is convenient retail; it is not particularly sophisticated healthcare.
Persistent or worsening fatigue deserves assessment, particularly when accompanied by breathlessness, marked palpitations, weight change, neurological symptoms or abnormal bleeding. Supplementation makes most sense when there is a plausible nutritional need, a demonstrated deficiency or another defined evidence-based purpose.
What fatigue actually asks us to think about
The difficulty with fatigue is that it is both extremely common and spectacularly non-specific. Sleep debt, caring responsibilities, under-fuelling, alcohol, stress and a punishing diary can all leave somebody exhausted without a micronutrient deficiency being the central problem. Equally, persistent tiredness can be the presenting feature of iron-deficiency anaemia, B12 or folate deficiency, thyroid dysfunction, diabetes, inflammatory illness, depression, sleep-disordered breathing or medication effects. Context matters more than whichever supplement currently owns the algorithm.
That is why the sensible sequence is assessment first and supplementation second. A useful history may include sleep quality, diet, menstrual pattern, weight change, medicines, gastrointestinal symptoms and whether fatigue is accompanied by breathlessness, palpitations, neurological symptoms or reduced exercise tolerance. Blood tests are sometimes appropriate, but they should answer a clinical question rather than become an indiscriminate shopping list.
There is also a basic distinction between correcting a deficiency and attempting to push a normal level higher in the hope of feeling superhuman. Nutrients are essential; that does not mean progressively larger doses produce progressively larger benefits. Biology has an irritating habit of being less impressed by marketing than marketing departments are.
Iron Energy+
PRODUCT CONTEXT · This is a retail example of an iron-containing supplement, not a recommendation to treat tiredness or suspected anaemia without assessment.
This combines iron with vitamin C, folic acid and B12. Menstrual blood loss, including heavier or changing bleeding around perimenopause, can make iron deficiency relevant for some women, but suspected iron-deficiency anaemia deserves blood testing and an explanation for why iron is low. Iron is not a harmless energy tonic: unnecessary supplementation can cause adverse effects and can distract from the cause of persistent symptoms.
Vitamin B12 Dual Power
PRODUCT CONTEXT · B12 replacement matters when deficiency exists. Taking more B12 does not reliably create extra energy in somebody who is already replete.
B12 deficiency may result from inadequate intake or impaired absorption, and those are not the same clinical problem. Vegans and some vegetarians may have a clearer dietary rationale for supplementation, whereas pernicious anaemia or significant malabsorption may require medical assessment and prescribed replacement. Folate deserves care too: treating folate deficiency without recognising co-existing B12 deficiency can improve the blood picture while neurological injury continues, so B12 status matters when deficiency is suspected.
02 · PERIMENOPAUSE & MENOPAUSE
Perimenopause is not a single symptom and it is rarely a tidy, linear process. Fluctuating ovarian hormones can affect sleep, temperature regulation, mood, concentration, skin, body composition and energy at different times and to very different degrees. Persistent fatigue, significant mood change, heavy or irregular bleeding, palpitations or a major change in wellbeing should not automatically be attributed to hormones.
There are legitimate midlife nutritional priorities — adequate protein, maintaining muscle, bone health, vitamin D and correcting deficiencies — but supplements should sit alongside appropriate assessment, lifestyle measures and evidence-based menopause treatment where needed. NICE also advises discussing the uncertainty around the safety, quality and purity of unregulated complementary preparations and the possibility of medicine interactions.
Midlife nutrition is bigger than a supplement shelf
During perimenopause and after menopause, the conversation is often narrowed to hormones or a bottle of something promising hormone balance. In practice, maintaining muscle, bone strength, cardiovascular health and a workable relationship with food is more useful. Adequate protein, resistance exercise, dietary calcium, vitamin D, sleep, alcohol intake and smoking status all sit in that wider picture. Supplements can support particular gaps; they cannot carry the whole job.
Menopause can also overlap with conditions that produce similar symptoms. Heavy or prolonged bleeding can contribute to iron deficiency. Poor sleep can drive fatigue and concentration problems. Palpitations may occur during perimenopause but should not automatically be filed under hormones without considering their pattern and associated symptoms. Hair change, weight change and low mood have similarly broad differentials.
The point is not to medicalise every midlife change. It is to avoid the opposite mistake: deciding that every symptom in a woman in her forties or fifties must be menopause and therefore belongs in the supplement aisle. Evidence-based menopause care and sensible nutrition can coexist perfectly well.
Pure Creatine Monohydrate
THE EVIDENCE · Creatine monohydrate has a substantial evidence base for repeated high-intensity exercise and supporting strength and lean-mass gains alongside resistance training. That is different from treating menopause symptoms.
For women through midlife, preserving muscle and strength is relevant to function and healthy ageing. There is also developing research into cognition, but it should not be presented as a treatment for menopausal brain fog. Creatine monohydrate is the form with the deepest evidence base. People with kidney disease or significant medical complexity should seek individual advice before supplementation.
Vitamin D3 4000iu + K2
DOSE MATTERS · Each tablet contains 4,000 IU (100 micrograms) vitamin D3. That is a high-dose product, not a routine menopause supplement.
For most UK adults, routine autumn and winter advice is 10 micrograms (400 IU) vitamin D daily. This product provides ten times that amount and reaches the adult daily upper limit, so it should not be chosen simply on the assumption that more is better. Individual requirements can differ, particularly where deficiency has been identified. The K2 component also warrants caution for people taking vitamin-K-antagonist anticoagulants such as warfarin.
03 · SLEEP, STRESS & FEELING WIRED
Poor sleep has become a supplement category in its own right. Before reaching for a product, it is worth considering caffeine, alcohol, hot flushes, anxiety, medicines, restless legs, pain and obstructive sleep apnoea. A supplement cannot reliably compensate for an untreated reason for repeatedly poor sleep.
Why sleep supplements so often disappoint
Sleep is particularly vulnerable to simple explanations. Magnesium deficiency is real; that does not mean magnesium deficiency explains most insomnia. A person can also fall asleep quickly and still have poor-quality sleep because of hot flushes, alcohol, pain, restless legs or obstructive sleep apnoea. The symptom 'I sleep badly' therefore needs considerably more unpacking than a social-media advert can manage.
Caffeine deserves special mention because its half-life means an afternoon coffee can still be biologically relevant at bedtime even when somebody feels able to fall asleep. Alcohol can shorten sleep latency while fragmenting later sleep. Menopausal vasomotor symptoms may repeatedly wake somebody who then experiences the following day as fatigue, irritability and brain fog. None of these mechanisms is fixed by simply adding another capsule.
Where a supplement is being considered, the useful questions are mundane but important: what is the actual ingredient, what is the elemental or active dose, what evidence exists for that formulation, what medicines could it interact with, and is there a reason this particular person should avoid it? That is a rather better filter than 'TikTok says everyone is deficient'.
Magnesium Glycinate 3-in-1
EVIDENCE CHECK · Magnesium is nutritionally important, but evidence for routinely treating insomnia with magnesium supplements is mixed and generally low certainty. Any sleep benefit should be described modestly.
Different magnesium salts provide different amounts of elemental magnesium and have different gastrointestinal effects. Supplementation may be more relevant where dietary intake is inadequate or another reason for increased need exists. Higher supplemental doses can cause diarrhoea, and magnesium can interfere with absorption of some medicines, including certain antibiotics and thyroid replacement, if taken too closely together. Kidney disease also changes the safety calculation.
04 · THE ASHWAGANDHA GUMMY BOOM
Ashwagandha is heavily promoted around stress, sleep and cortisol. Human studies of particular extracts and doses have reported some improvements in measures of perceived stress or sleep, but the evidence base is relatively small, studies are generally short, and products are not interchangeable. Those findings should not be turned into a promise that a retail gummy treats anxiety, insomnia or a supposed cortisol disorder.
SAFETY FIRST · Ashwagandha is not automatically benign because it is herbal. Avoid it in pregnancy unless specifically advised otherwise. Particular caution is warranted with thyroid disease or thyroid medication, liver disease, autoimmune conditions, sedating medicines, medicines for diabetes or blood pressure, immunosuppressants, and around surgery. Rare cases of liver injury have been reported, and long-term safety remains uncertain.
The UK advertising regulator has already upheld complaints about social-media advertising for ashwagandha gummies where prohibited health or anxiety claims were made. That is useful context: the interesting science around an ingredient does not give advertisers permission to turn a food supplement into a treatment claim.
Cortisol: the internet's favourite villain
Cortisol is an essential glucocorticoid hormone involved in metabolism, immune regulation, blood pressure and the normal response to stress. It follows a daily rhythm and changes in response to illness, sleep, exercise and psychological stress. That is very different from the loose online idea that ordinary tiredness, abdominal weight gain, poor sleep or feeling frazzled proves somebody has 'high cortisol'. Those symptoms are non-specific and cannot diagnose a cortisol disorder.
Clinically significant cortisol excess or deficiency belongs in proper medical assessment and, where indicated, validated testing. Consumer supplements should not be used as a substitute for that process. This matters because the phrase 'balances cortisol' sounds pleasantly scientific while often avoiding the awkward question of what abnormality has actually been demonstrated.
Ashwagandha research is worth following, particularly studies examining perceived stress and sleep, but the sensible interpretation remains narrower than the advertising. Different extracts, doses and populations cannot simply be collapsed into one universal claim. Short-term trial findings also tell us much less about years of routine use, interactions and uncommon adverse effects.
TRIP Cherry Ashwagandha Gummies
THE FACEBOOK TEST · The useful question is what the serving actually contains, not how dramatic the front-of-pack number looks.
Current brand information states that a two-gummy serving provides 300 mg of KSM-66 extract. Larger figures seen in some retail descriptions can refer to herbal-equivalent calculations or pack totals; those numbers are not interchangeable with the amount of extract in a serving. The gummies also contain glucose syrup and sugar, plus vitamins D2, B6 and B12. None of that proves benefit or harm by itself — it simply makes accurate label reading more useful than headline arithmetic.
Ashwagandha Calm+
PRODUCT CONTEXT · A conventional KSM-66 supplement format. The same evidence limitations, interaction checks and safety cautions still apply.
Studies of some ashwagandha preparations are interesting, but they are not a blank cheque for every formulation, dose or advertising claim. A retail supplement should not be used to self-diagnose or treat “high cortisol”, anxiety or insomnia. If you take regular medication or have a significant medical history, checking suitability before use is considerably more useful than trusting an influencer with a ring light.
05 · BRAIN FOG & CONCENTRATION
Brain fog is a description, not a diagnosis. Sleep loss, stress, menopause, low mood, iron or B12 deficiency, medication and other health problems can all contribute. Correcting a deficiency is very different from buying a nootropic because the packaging contains a mushroom and a picture of a brain.
Brain fog deserves a wider lens
People use 'brain fog' to describe forgetfulness, word-finding difficulty, poor concentration, slowed thinking or simply feeling mentally absent. Those experiences can be very real while still having multiple possible drivers. Menopausal transition is one; fragmented sleep, depression, anxiety, iron or B12 deficiency, thyroid dysfunction, medication, alcohol and overwhelming workload are others.
That breadth matters when looking at nootropics. An ingredient can have an interesting mechanism in laboratory work without having convincing evidence that taking it improves meaningful cognition in the population buying it. Small studies can generate useful hypotheses, but they are not the same thing as an established treatment. Lion's Mane currently sits much closer to the interesting-research end of that spectrum than the proven-treatment end.
If cognitive change is progressive, markedly different from usual, affecting day-to-day function or accompanied by neurological symptoms, the priority changes from supplement comparison to clinical assessment. A mushroom capsule is not a diagnostic pathway.
Lion’s Mane Focus+
EVIDENCE CHECK · Lion’s Mane has scientific interest behind it, but human evidence remains limited and mixed. It is not an established treatment for brain fog, ADHD, dementia or menopausal cognitive symptoms.
Small human studies have produced some encouraging findings, while other controlled work has not shown broad improvements in cognition or mood. Product extracts, doses and study populations also differ. That makes this an area for cautious interest rather than confident therapeutic claims.
06 · HAIR, SKIN & NAILS
Hair changes in midlife are common and emotionally significant, which makes the category extremely easy to market into. Hormones, genetics, nutrition, thyroid disease, illness, stress and weight change can all matter. A beauty supplement cannot tell you which one is happening.
Hair changes: investigate the pattern, not just the product
Hair shedding and thinning are often bundled together commercially even though they are not one problem. Diffuse shedding after illness, major stress, rapid weight loss or nutritional restriction looks different from patterned androgen-related thinning, inflammatory scalp disease or patchy alopecia. Perimenopause may coincide with changes in hair density and texture, but timing alone does not prove causation.
Protein and adequate overall energy intake matter to hair biology, and genuine deficiencies in nutrients such as iron or zinc can be relevant in the right context. The answer is not to assume that everybody with hair concerns needs high doses of everything associated with hair on a label. Excessive supplementation can create its own problems, and some nutrients have relatively narrow safety margins.
Biotin is a useful example of the gap between reputation and evidence. Deficiency can cause hair and skin abnormalities, but true deficiency is uncommon. Meanwhile high-dose biotin has a very practical downside: it can distort certain laboratory results. That is why telling a clinician what supplements you take is not administrative trivia; occasionally it changes how a result should be interpreted.
Biotin Growth+
EVIDENCE CHECK · Biotin is important when deficiency is present, but evidence for improving hair growth in otherwise well-nourished people is much weaker than the marketing suggests.
This product combines high-dose biotin with zinc and selenium. High-dose biotin can interfere with laboratory immunoassays and produce misleading results, including some thyroid tests and certain cardiac investigations. If you take biotin and are having blood tests, tell the clinician and laboratory rather than assuming a supplement is irrelevant to the result.
A sensible supplement checklist · What problem are you actually trying to solve? Is there a plausible deficiency or defined purpose? What is the active dose per serving? Is the claim stronger than the evidence? Could it interact with medicines or affect blood tests? If those questions are hard to answer, the checkout button can wait.
THE SHORT VERSION
Persistent symptoms deserve assessment before they deserve a shopping basket. Supplements are most defensible when they correct a genuine nutritional gap or are used for a clearly defined purpose supported by evidence. The broader the promise on the advert, the more carefully it deserves reading.
How to read a supplement label without losing an afternoon
Start with the serving size rather than the largest number on the front. Check whether the stated quantity refers to the active extract, an elemental amount, a herbal equivalent or the total across several capsules or gummies. Then look at the rest of the formulation. Combination products make it easy to duplicate nutrients when somebody is already taking a multivitamin or several targeted products.
Next, separate an authorised nutritional claim from a therapeutic promise. 'Vitamin D contributes to normal immune function' is not the same statement as saying a product prevents or treats an infection. Similar caution applies to words such as detox, hormone balance, adrenal support and cortisol control. Scientific vocabulary can make a claim sound precise without making the underlying claim any better supported.
Finally, remember the boring bits: dose, duration, interactions, pregnancy, kidney or liver disease, upcoming surgery and existing medicines. If the proposed benefit is vague but the list of cautions is long, that should influence how casually the product is treated. Supplements occupy a peculiar retail space where a brightly coloured pouch can contain a biologically active substance. The pouch does not get the final vote; the pharmacology does.
Creatine monohydrate has a strong evidence base for exercise performance and strength when used appropriately. Iron and B12 are clinically important where deficiency exists. Vitamin D is important, but dose matters. Evidence for magnesium as a routine sleep treatment is mixed. Ashwagandha has some human research but meaningful cautions and uncertain long-term safety. Lion’s Mane remains investigational rather than established. Biotin is considerably less persuasive as a universal hair solution than its reputation suggests.
