During menopause, there are some simple steps to manage brain fog and support clearer thinking.
Brain fog during menopause and perimenopause can affect memory, concentration and mental clarity. Ever walked into a room and forgotten why you went there? Lost your train of thought halfway through a sentence? Or struggled to focus on something that would normally feel easy? If this sounds familiar, you’re not alone. Menopause brain fog is a term often used to describe these changes. Hormonal fluctuations may play a part, but sleep, stress, nutrition and other aspects of health can also influence how you feel.¹ Understanding the possible causes can help you find practical ways to support your wellbeing.
What does menopause brain fog feel like?
Brain fog isn’t a medical diagnosis. It describes a collection of experiences that may include:
- Forgetting names, words or why you entered a room
- Losing your train of thought during conversations
- Finding it harder to concentrate or stay organised
- Feeling mentally tired or less sharp than usual
These changes can be frustrating, especially when you’re juggling work, family and everyday responsibilities. The HSE recognises problems with memory and concentration as symptoms that can occur during perimenopause and menopause.¹
Why does brain fog happen during menopause?
During perimenopause, oestrogen and progesterone levels fluctuate before eventually declining. These hormones have roles beyond reproductive health and are involved in processes related to brain function, mood and sleep. Oestrogen interacts with areas of the brain involved in learning and memory, including the hippocampus. Changes in oestrogen during the menopause transition may therefore contribute to some of the memory lapses and concentration difficulties women experience.² Progesterone also acts on the brain and nervous system and may influence sleep and neuronal activity.³
Hormones aren’t the whole story, though. Hot flushes and night sweats can interrupt sleep, while stress, tiredness and changes in mood can make concentrating more difficult. Looking at your overall wellbeing is often more useful than searching for one single cause.
How long does menopause brain fog last?
There is no set timeline. Some women notice changes during perimenopause that ease as they move through the menopause transition, while others experience difficulties for longer. If brain fog is persistent, getting worse or affecting everyday life, speak to your GP. Memory and concentration changes can have causes other than menopause, so it is worth discussing symptoms rather than assuming they are hormonal.
How can you support clearer thinking during menopause?
Eat a balanced, nutrient-rich diet
Your brain needs a regular supply of energy and nutrients. Build meals around a variety of vegetables and fruit, wholegrains, pulses, nuts, seeds, healthy fats and sources of protein. Magnesium-rich foods, including leafy greens, nuts, seeds and wholegrains, are useful additions. Magnesium contributes to normal nervous system function and normal psychological function. B vitamins also have important roles in normal energy-yielding metabolism and nervous system function. You can find them in foods such as eggs, wholegrains, leafy greens and legumes. Rather than looking for one particular “brain food”, aim for variety and consistency.
Include omega-3 fats
Oily fish such as salmon, sardines and mackerel provide the omega-3 fatty acids EPA and DHA. Flaxseeds, chia seeds and walnuts provide plant-based omega-3 fats. If you rarely eat oily fish, you may wish to consider an omega-3 supplement. DHA contributes to the maintenance of normal brain function when the required daily intake is met. You can also explore Evergreen’s Omega & Fish Oils collection.
Prioritise quality sleep
It’s harder to feel mentally sharp when you’re running on poor sleep. Hot flushes, night sweats and changing sleep patterns can make restful nights more difficult during menopause.¹ Try keeping your bedroom cool, following a regular bedtime routine, limiting caffeine later in the day and allowing time to wind down before bed. If sleep difficulties continue, speak to your GP rather than simply putting them down to menopause.
Find manageable ways to reduce stress
Stress and mental overload can make it harder to concentrate. A short walk, breathing exercises, yoga, meditation or time away from screens may help you build moments of calm into a busy day. You don’t need an elaborate routine. Choose something realistic that you can return to regularly.
Keep your body and brain active
Walking, swimming, cycling, Pilates and strength training are all ways to stay active. Choose movement you enjoy and can maintain consistently. Keep yourself mentally engaged, too. Reading, learning a skill, taking up a hobby or trying a new activity can add variety and enjoyment to your routine.
Which nutrients support normal brain and nervous system function?
A varied diet is the starting point, but certain nutrients have recognised roles in normal everyday function. Magnesium contributes to normal nervous system and psychological function, while several B vitamins contribute to normal energy-yielding metabolism and nervous system function. DHA, an omega-3 fatty acid, contributes to the maintenance of normal brain function at the required daily intake. These nutrients support normal functions; supplements should not be viewed as a treatment for menopause brain fog. If you are considering a supplement, check whether it overlaps with anything you already take and seek advice if you are unsure.
BioCare nutritional support to consider during menopause
If you would like additional nutritional support alongside a balanced diet and healthy lifestyle, these three BioCare products offer different options.
BioCare Menopause Multinutrient
Formulated for women during and after menopause, BioCare Menopause Multinutrient provides a combination of vitamins and minerals, including B vitamins, magnesium, zinc and vitamin D. It offers broader nutritional support for this stage of life rather than focusing on one symptom.
BioCare Magnesium Glycinate
BioCare Magnesium Glycinate provides magnesium, which contributes to normal nervous system function, normal psychological function and the reduction of tiredness and fatigue. It may be worth considering if you need help meeting your daily magnesium intake.
BioCare Mega EPA
BioCare Mega EPA provides the omega-3 fatty acids EPA and DHA. It offers a convenient way to supplement your intake if oily fish is not a regular part of your diet. DHA contributes to the maintenance of normal brain function when the required daily intake is met.

When should you speak to your GP about brain fog?
Not every memory or concentration change should automatically be attributed to menopause. If your symptoms are new, severe, persistent, worsening or interfering with daily life, arrange an appointment with your GP. A healthcare professional can discuss your symptoms, consider other possible causes and help you decide what support is appropriate.

Menopause brain fog: frequently asked questions
Is brain fog a symptom of menopause?
Yes. Problems with memory and concentration are recognised symptoms of perimenopause and menopause.¹ They can occur alongside sleep disruption, tiredness and mood changes. However, brain fog is not specific to menopause, so persistent or concerning symptoms should be discussed with your GP.
Can brain fog start during perimenopause?
Yes. Perimenopause is the period leading up to menopause, when hormone levels can fluctuate and symptoms may begin. Some women notice changes in concentration or memory during this stage, even before their periods stop.
Can poor sleep make menopause brain fog worse?
Poor sleep can leave you feeling tired and make it more difficult to focus during the day. If hot flushes, night sweats or other symptoms are regularly disrupting your sleep, speak to your GP about ways to manage them.
Do supplements get rid of menopause brain fog?
No supplement should be relied on to treat brain fog. A balanced diet can help you obtain nutrients needed for normal brain and nervous system function, while supplements may help you meet particular nutritional needs. Persistent symptoms deserve medical attention.
Look at the bigger picture
Menopause brain fog can be frustrating, but you do not need to tackle every aspect of your routine at once. Start with the basics: regular meals, good sleep habits, enjoyable movement and manageable ways to reduce stress. Consider nutritional support where it is appropriate for you. Most importantly, pay attention to changes that feel unusual or interfere with your daily life, and seek advice when you need it. Looking after your wellbeing during menopause means finding support that suits you.
