Brain Fog

Clear The Mist - How To Combat Brain Fog

Many of us have experienced moments where our mind feels clouded, making concentration and memory recall more challenging than usual. This is commonly referred to as brain fog and can be very frustrating to deal with. While it’s not a medical diagnosis in itself, brain fog is a symptom that can significantly impact your quality of life.

What Is Brain Fog?

Severe brain fog can be debilitating, particularly if you need to function day-to-day in a high-performance or pressured environment at home or work. It can affect your levels of confidence, self-esteem and performance.

Brain Fog Causes

Many factors can contribute to brain fog such:

Lifestyle Factors: Poor sleep quality, lack of exercise, and a nutrient deficient diet.

Medical Conditions: Chronic fatigue syndrome, fibromyalgia, anaemia, depression, thyroid disorders. diabetes and post viral syndrome are among the conditions associated with brain fog.

Medications: Certain medications can affect cognitive function as a side effect.

Stress and Mental Health: High-stress levels and mental health issues like anxiety and depression are closely linked to brain fog.

Other factors that can affect brain fog are age, hormonal changes, nutritional deficiencies, and even the aftermath of conditions such as COVID.

Brain Fog Symptoms

Brain fog manifests as cognitive impairments including:

Brain Fog Symptoms
  • Mood swings
  • Lack of focus
  • Irritability
  • Confusion
  • Trouble sleeping,
  • Low energy or fatigue
  • Forgetfulness
  • Trouble concentrating
  • Low motivation
  • Difficulty making decisions

Menopause Brain Fog

Brain fog during perimenopause and menopause is a real and sometimes challenging symptom faced by many going through the hormonal transition. 

Hormonal fluctuations - particularly a decrease in oestrogen and testosterone - are believed to play a critical role in this. When the levels of these hormones begin to fall during perimenopause and menopause, you can experience a range of cognitive symptoms including memory loss, difficulty staying focused, losing your train of thought, and getting confused easily.

Oestrogen is involved in regulating neurotransmitters that affect cognition, including serotonin and dopamine. As these hormone levels fluctuate, so does the clarity of thought, making brain fog a frequent complaint amongst menopausal women.

Testosterone strengthens nerves in the brain and contributes to mental sharpness and clarity, as well as overall energy levels. It also strengthens arteries that supply blood flow to the brain, which is crucial to protect against loss of memory.

Brain fog is very common. In research conducted by the British Menopause Society, almost 40% of the women interviewed reported issues with memory and concentration as they go through the menopause.*

The COVID Connection

Post-COVID brain fog has emerged as a lingering symptom for many individuals recovering from the virus due to consequences such as inflammation and the overall stress of dealing with the illness. 

In one study, 7.2% of people who reported having long COVID experienced brain fog, and this symptom was more common in those who had a more severe case of COVID-19. 



Chronic stress can increase blood pressure, weaken the immune system, and trigger depression. According to a study undertaken in 2017, stress can also cause mental fatigue.

Chronic stress leads to sustained high levels of cortisol, the body's stress hormone. High cortisol levels can impair cognitive function such as memory and concentration, contributing to brain fog.

Stress can also disrupt the balance of neurotransmitters, such as serotonin and dopamine, which play crucial roles in mood regulation, focus, and cognitive processing. Imbalances in these chemicals can lead to difficulties in concentrating and memory lapses.

Chronic stress is linked to increased inflammation in the body, which can negatively affect brain function and lead to symptoms of brain fog.


Brain fog is a known side effect of certain medications, such as certain painkillers, antidepressants and sleep medications.

Brain fog can also occur after cancer treatments. This is often referred to as ‘chemo brain’.


The NHS recommends that adults should aim for 7 – 9 hours of sleep each night. However, Nuffield Health surveyed 8,000 adults in the UK and found that most adults are getting an average of 5.9 hours of sleep every night in 2023.

Poor sleep quality and sleep deprivation can significantly contribute to cognitive impairments, including reduced attention span, memory issues, and decreased mental clarity.


How To Clear The Fog

Brain fog can be frustrating, but relief is possible. You should not ignore your symptoms because, if left untreated, brain fog can impact your ability to function and undertake tasks.

Addressing brain fog involves treating underlying causes or making lifestyle changes to improve cognitive function, these include:

SleepEnsuring adequate, high-quality sleep can significantly reduce symptoms of brain fog. Aim for 7-9 hours per night and maintain a consistent sleep schedule.

Nutrition: A diet rich in fruits, vegetables, whole grains, and omega-3 fatty acids (found in fish) can support brain health. Avoiding excessive alcohol, sugar, and processed foods is also advisable.

Exercise: Regular exercise increases blood flow to the brain and has been linked to improved cognitive function. Activities like walking, swimming, and yoga can be particularly beneficial.

Stress Management: Techniques such as mindfulness, meditation, and yoga can reduce stress and improve mental clarity.

Hydration: Adequate hydration is crucial for maintaining cognitive function. Aim for 8 glasses of water daily.

Mental Stimulation: Engage in activities that challenge your brain, such as puzzles, learning a new skill, or reading.


Magnesium is an essential nutrient that plays a pivotal role in over 300 physiological processes in the body, including those involved in energy production, sleep quality, and the regulation of neurotransmitters. It’s, therefore, no wonder that magnesium has been identified for its potential to alleviate brain fog.

Magnesium aids in improving brain function by supporting the nervous system, enhancing sleep quality, reducing inflammation, and reducing stress levels—all factors that can mitigate the symptoms of brain fog. For those individuals navigating menopause, magnesium's role in balancing hormones further highlights its significance.

Marine Magnesium Supplements

Marine Magnesium can help to restore clarity for anyone experiencing brain fog. Our bodies require this micromineral to function healthily however our bodies do not synthesise or store magnesium. It is therefore essential that we get an adequate daily intake from our diet or high-quality food supplements. 

Marine Magnesium Supplement

“There are so many magnesium supplements on the market, which one should I choose?”

We understand how overwhelming it can be when deciding on which Magnesium supplement you should be taking. The key to selecting the most suitable supplement lies in understanding the difference in the quality and purity of the different supplements available.

Our Marine Magnesium is sourced from purified seawater and is in the form of magnesium hydroxide. Due to its natural and pure source, it is quickly absorbed by the body making it more effective and very gentle on the stomach. 

Marine Magnesium contains only 3 ingredients:

  1. Magnesium (from seawater)
  2. Organic baobab (natural prebiotic) 
  3. A natural, tapioca capsule shell. 

Most other magnesium supplements such as magnesium glycinate, citrate, picolinate and taurate are synthetic and manufactured using chemicals and often contain numerous additives, fillers and bulking agents. 

Like your food, it is best to avoid supplements that are overprocessed and contain unnecessary additives that can often affect the supplement's effectiveness and even be harmful to health. Remember to always read ingredient labels to help you choose your supplements wisely - choose NAKED.

Best Magnesium Supplement

Marine Magnesium has been voted as one of the best magnesium supplements by experts in The Independent. Maz Packham, a nutritionist says:

“Magnesium is needed for more than 300 different reactions in the body and is involved in everything from sleep, mood, to bone health and blood pressure, even energy production. It’s often referred to as nature’s tranquiliser because it’s a natural muscle relaxer.

This supplement (Marine Magnesium) is made from pure seawater plus it has added prebiotic to support the gut. The only other ingredient is its tapioca shell.
Plus, the brand uses biodegradable packaging which is another tick for me, and the pouches are easy to travel with,”

Effects of sugar on the brain

The Bittersweet Truth – The Effects Of Sugar On The Brain

In this blog our pharmacist Dimple delves into the relationship between sugar consumption and its effects on the brain. Dimple aims to unravel the connection between excessive sugar intake and its impact on brain inflammation and the heightened risk of Alzheimer's disease.  In a world where sweet indulgences are abundant, understanding the potential consequences on cognitive health becomes imperative.


What Is Alzheimers Disease?

In our lifetime, one in two of us will be affected by dementia whether this is through caring for someone with the condition, developing it ourselves, or both. The NHS defines Alzheimer's disease a progressive neurodegenerative disorder that primarily affects older adults, typically becoming noticeable after the age of 65. The symptoms of Alzheimer's disease worsen over time and can be divided into early, middle, and late stages.

(NHS Alzheimers Disease Symptoms)

Although there is currently no cure for Alzheimer's, evidence points to a link between high sugar intake and Alzheimer’s risk. (Alzheimers Research UK 2023)

Dementia is not a specific disease but is a general term used to describe a group of symptoms that affect the ability to think, remember, and perform everyday tasks. Alzheimer's disease is the most common type of dementia.

Alzheimers Disease Symptoms

Alzheimer's disease unfolds in distinct stages, each marked by varying symptoms that progressively intensify, posing challenges for both individuals with the condition and their caregivers.

In the early stages, subtle memory lapses manifest as forgetfulness about recent conversations, misplacement of items, and difficulty recalling names and objects.
Concurrently, signs of mood changes, anxiety, and repetitive questioning may emerge. As the disease advances into the middle stage, memory deterioration becomes more pronounced, leading to difficulty recognizing familiar faces and an escalation of confusion and disorientation.

Additional symptoms include impulsive behavior, delusions, speech and language problems, disturbed sleep, and changes in mood. Individuals often require support for daily activities as cognitive decline accelerates. In the later stages, full-time care becomes a necessity.

What Is Type 3 Diabetes?

Evidence shows that poorly controlled blood sugar can increase the risk of developing Alzheimer’s Disease. This relationship is so strong that Alzheimer’s disease is often referred to as diabetes of the brain or Type 3 diabetes.

Insulin Resistance

Insulin is vital for glucose regulation and plays a crucial role in maintaining cognitive function. However, when the brain becomes resistant to insulin, it struggles to utilise glucose effectively, potentially contributing to the development and progression of Alzheimer's disease.

Does sugar cause inflammation?

Excessive sugar intake has been implicated in chronic inflammation throughout the body, and the brain is no exception. Neuroinflammation, triggered by the body’s response to poorly controlled sugar levels, is now recognised as a potential contributor to Alzheimer's disease. The inflammatory response in the brain can lead to the formation of beta-amyloid plaques, a hallmark of Alzheimer's.

Excessive Sugar

Symptoms of too much sugar in your body

It's important to note that the body reacts differently to sugar depending on individual health, metabolism, and the amount and type of sugar consumed. Here are some common symptoms associated with excessive sugar intake:

  • Weight gain: high sugar intake, especially from sugary drinks, can contribute to weight gain due to its high calorie content and its ability to increase hunger and craving for more sugary foods.
  • Low energy: consuming a lot of sugar can cause rapid spikes in blood sugar levels, followed by sharp drops, which can lead to feelings of fatigue, irritability, and hunger.
  • Dental problems: sugar is a leading cause of dental cavities and gum disease as sugar feeds the harmful bacteria in the mouth.
  • Mood changes: excessive sugar consumption can lead to mood swings, irritability, and may even contribute to symptoms of depression and anxiety.
  • Skin issues: high sugar diets can exacerbate skin conditions such as acne and can contribute to premature aging of the skin.
  • Fatty liver disease: excessive intake of fructose, a type of sugar, can lead to a build-up of fat in the liver, which can progress to non-alcoholic fatty liver disease.
  • Impact on Sleep: High sugar consumption, especially close to bedtime, can interfere with your ability to have a restful night's sleep.

The Scientific Evidence

A 2021 study involving 1865 adults over 19 years found a higher risk of Alzheimer's, all types of dementia, and stroke in people who consumed the most sugar, especially in the form of drinks.

A study with 37,689 people found a link between high sugar intake and increased Alzheimer’s risk among women.

A review undertaken in 2022 found that people with type 2 diabetes are up to 90% more likely to develop Alzheimer’s disease or another type of dementia.

A 2022 study with 4,932 people found that the link between Alzheimer’s, high blood sugar, and high cholesterol can begin as early as age 35. Researchers followed the participants over decades. They found that managing cholesterol and blood sugar levels early may help lower the risk of developing Alzheimer’s later. 

Metabolic Gold

Metabolic Gold is our natural supplement formulated using pure artichoke leaf extract and bergamot fruit extract. These two botanicals contain bioactive compounds that provides effective support to help control sugar levels and therfore reduce your risk of dementia.

Metabolic Gold will help to improve sugar metabolism, reduce insulin resistance and restore normal cholesterol balance and weight management.

Metabolic Gold

How does Metabolic Gold work?

Metabolic Gold will help to regulate the enzyme, alpha-glucosidase, which is involved in the breakdown of complex carbohydrates into simpler sugars. By inhibiting this enzyme, you can slow down the absorption of glucose from the digestive tract, leading to more stable blood sugar levels.

The cholesterol-lowering effects are achieved through stimulating bile flow which in turn helps to break down, bind and excrete excess cholesterol from the body.

Here at The Naked Pharmacy we ensure all of our supplements are formulated using scientific evidence to ensure that they are safe and effective. Here is some trial data to support the use of Metabolic Gold to help manage your sugar levels and reduce the risk of dementia.

A study undertaken in 2019 involving 60 participants found that supplementation with bergamot fruit extract resulted in a significant reduction in sugar levels, LDL cholesterol and triglycerides.

Another study found that supplementing with artichoke leaf extract for 60 days improved sugar control, insulin sensitivity, and reduced LDL cholesterol and weight circumference.

Protecting the Brain

It’s never too late to make the lifestyle changes needed to protect your health. Here are a few things you can do to reduce your risk by managing your sugar levels.

Balanced Nutrition

Healthy diet

Opt for a diet rich in whole foods, emphasising fruits, vegetables, lean proteins, and whole grains. Minimise processed foods and refined sugars. Be wary about hidden sugars in processed foods, drinks, and snacks. Read labels and choose low-sugar alternatives when possible.

Foods with Anti Inflammatory properties

Eat foods with anti-inflammatory properties such as beans, avocados, green leafy vegetables, berries, fish and incorporate spices such as turmeric and ginger into your cooking.

What are Inflammatory Foods?

Avoid foods that can cause inflammation such as processed meat, red meat (steak, hamburgers), bread and pasta made with white flour, baked goods (cakes, cookies) and bad sugars.

Our Natruflex Turmeric capsules contain high-strength turmeric containing 95% curcuminoids (the compounds responsible for the anti-inflammatory effects) alongside black pepper extract to increase absorption of the turmeric and we’ve also added in Marine Magnesium.

Regular Exercise

Physical activity not only helps regulate blood sugar levels but also promotes overall brain health by enhancing blood flow and reducing inflammation.

Regular Exercise

Cognitive Stimulation

Mental stimulation is vital for maintaining cognitive function. Engage in activities that stimulate the brain, such as puzzles, reading, and learning new skills.
