Supplements & Lifestyle Support for Menopause Brain Fog - and How This Protects Long Term Brain Health
Last week I wrote about why Alzheimer’s is now being looked at as a metabolic condition, and not simply as a disease of memory, but one of brain energy. Today, I want to bring that into everyday life, because while understanding the science matters, knowing what to do matters just as much.
I’m asked all the time in clinic: what are the best supplements to help with brain fog in menopause? This question often comes long before women ever worry about long term brain health. Which makes sense as the same shifts affecting concentration, word recall and mental clarity are often connected to how the brain is accessing fuel.
So, in this blog I’ll be focusing on support and what helps the brain use energy more efficiently right now, while also supporting resilience over time.
If you haven’t read last week’s blog on the background science, I’ve linked it here. It’s helpful for better understanding, but you don’t need it to follow along.
Why Brain Fog Is Often an Energy Issue First
I’m not going to revisit everything from last week, as today is about practical steps. But I do want to briefly touch on menopausal brain fog.
When women are asking me about supplements to help with brain fog in menopause, they’re rarely describing memory loss or confusion. It’s more slower thinking, word finding difficulty, mental fatigue by mid afternoon, or struggling to concentrate the way they used to.
And this is where energy comes into it. We know that oestrogen helps brain cells use glucose efficiently. It also supports insulin sensitivity and helps shuttle fuel into the cell so energy can be produced smoothly. As levels naturally decline during perimenopause and menopause, that system can become slightly less efficient.
Some research suggests brain glucose use may fall up to 30% during this transition. That doesn’t mean the brain is failing, it simply means it may need a little more support to access and use energy well.
At the same time, many women notice blood sugar shifts, they become a little more reactive to carbohydrates, more sensitive to skipped meals, more crashes in the afternoon and so on. This is because the brain relies heavily on stable fuel, and when glucose swings up and down, mental clarity often does the same.
These are positive findings, as energy problems are far more modifiable than structural decline.
The Daily Foundations That Actually Improve Brain Clarity
This is where we can make the biggest difference, as research shows that small, consistent changes can have a big impact on long term brain health.
1. Stabilise blood sugar first
The brain runs primarily on glucose, but it prefers steady fuel. That means:
-
Eating protein at breakfast (ideally 30-40g and always before coffee).
-
Including protein, healthy fats and fibre with carbohydrates to stabilise blood sugar.
-
Eating fibre first, then protein and fats, with carbohydrates and starchy vegetables last at meal times.
-
Avoiding long gaps without food, especially if you feel shaky or fatigued. Ideally eat balanced meals every 3-4 meals without snacking in between.
-
Walking for 10–15 minutes after meals.
Even small improvements in blood sugar stability can improve concentration and clarity within weeks.
2. Prioritise muscle, not just cardio
Strength training improves insulin sensitivity, supports metabolic flexibility and reduces visceral fat - all of which influence brain energy.
You don’t need overwhelming gym plans, just two to three sessions per week of resistance work is enough. That could be:
-
Bodyweight squats and lunges
-
Dumbbells at home
-
Machines at the gym
-
Resistance bands
Aim for weights that feel challenging for 6–10 repetitions. Building muscle is one of the most protective metabolic shifts you can make. It is what I like to call it 'your longevity currency'.
3. Protect sleep where possible
Deep sleep is when the brain clears out metabolic waste. I totally understand that perfect sleep isn’t realistic for everyone, especially new mums or shift workers. So the focus here is on improving quality where possible:
-
Keep the room cool and well ventilated.
-
Reduce light exposure before bed (dim lighting, minimise screens).
-
Support blood sugar stability in the evening.
-
Avoid large amounts of alcohol close to bedtime.
-
Minimise caffeine after 3pm and eat no later than 2-3 hours before bedtime.
Better sleep supports mental clarity more than most people think. It’s one of the most important tools for health and wellbeing.
4. Support metabolic flexibility through food
A Mediterranean style diet consistently shows benefit for long term cognitive health.
That means:
-
Oily fish 2–3 times per week (wild caught where possible).
-
Extra virgin olive oil.
-
Colourful vegetables.
-
Legumes and fibre/rich carbohydrates.
-
Adequate protein (eating 100-120g daily).
It’s less about restriction and more about nourishment and stability.
Supplements to Support Brain Health
Layered support always makes the biggest impact. I always recommend food and lifestyle first, then targeted supplementation to deeply support the body.
Here are the key supplements I recommend:
1. Supporting Brain Energy Production
If cognitive function is partly an energy issue, then we support energy first.
Creatine isn’t just for muscle. The brain has high ATP demands, and creatine helps buffer and regenerate energy inside cells. Emerging research suggests it may support cognitive resilience, particularly during stress or sleep disruption.
Women often store less creatine than men, and levels may fluctuate with hormonal changes. For some, this can result in mental fatigue that improves with supplementation.
(I’ve written a full blog on creatine if you fancy a little read here.)
B vitamins are essential for energy metabolism and neurotransmitter production. Even low-normal levels can contribute to fatigue and poor concentration. Supporting methylation pathways with B vitamins can improve mental clarity, particularly during menopause.
2. Calming an Overstimulated Brain
Brain fog isn’t always slow thinking, sometimes it’s scattered thinking.
Magnesium supports nervous system regulation, sleep quality and glucose balance. Magnesium glycinate can help calm overstimulation while supporting cellular energy processes. Plus, it’s well tolerated and gentle on digestion.
The brain is largely made of fat. Omega 3s support membrane fluidity, inflammation balance and neuronal signalling. Oily fish intake is ideal, but supplementation can be helpful if dietary intake is low or if in the presence of chronic inflammation.
3. Supporting Glucose Regulation
If blood sugar swings are contributing to mental dips, addressing this is key.
Yes, again. It plays a major role in blood sugar balance and insulin sensitivity.
Berberine has been heavily researched for its role in glucose regulation. There is evidence supporting its use in metabolic health, cholesterol, inflammation and even gut health, which are all key for brain health.
4. Supporting Neuroplasticity & Repair
Lion’s Mane has been used traditionally for centuries and is now being studied for its potential role in supporting nerve growth factor (NGF), involved in maintaining and regenerating neurons (brain cells responsible for thinking, memory and communication).
It may support cognitive function and mental clarity, particularly when combined with lifestyle foundations. This is my personal go to when I’m doing a speech, running a masterclass or just need to be hyperfocused.
A Little Reminder
Not everyone needs all of these. The most effective approach is targeted, based on symptoms, diet, blood markers and lifestyle. Supplements work best when they support the body’s natural systems.
Looking Beyond Brain Fog
It’s easy to dismiss brain fog as “just hormones.” But when we understand that many of these changes relate to how the brain accesses and uses energy, the perspective shifts.
And that shift works in our favour. Supporting blood sugar stability, building muscle, improving sleep quality and using targeted supplements aren’t extreme interventions, they’re small steps toward better metabolic resilience.
The reassuring part is that the brain is adaptable. It responds to nourishment, movement, rest and rhythm throughout life. And when we respond early, we’re not just supporting clarity today, we’re investing in long term brain health for decades to come.
