If you’re battling brain fog, struggling to concentrate at work, lacking focus, or simply starting to forget things, the chances are you’ll reach for a caffeine fix or sugary snack. But before you do, consider healthier and natural cognitive enhancers and nootropics.

First though, what exactly is brain fog, what causes it, and how can we combat it to enhance our cognitive function and overall well-being?


Brain fog is non-medical term used to describe a collection of symptoms that affect one's ability to think clearly. It includes:

Forgetfulness: Difficulty remembering information, simple tasks or where you placed your keys.

Lack of Focus: Struggling to concentrate on a task or maintain attention.

Mental Clarity: Feeling like your head is in a haze, making it hard to process information.

    These symptoms can severely impact your productivity and quality of life, making it essential to understand and address them.


    Several factors can contribute to brain fog, including:

    Poor Diet: A diet high in sugar and processed foods can lead to fluctuating blood sugar levels, affecting brain function.

    Lack of Sleep: Sleep is crucial for cognitive function. Chronic sleep deprivation can impair concentration and memory.

    Stress: Chronic stress increases cortisol levels, which can negatively impact brain health.

    Dehydration: Even mild dehydration can affect cognitive performance.

    Hormonal Changes: Hormonal imbalances, such as those occurring during “male menopause”, and low-testosterone levels, can cause brain fog.

    Medications: Certain medications have side effects that include cognitive impairment.

    Medical Conditions: Conditions like chronic fatigue syndrome, fibromyalgia, and depression are often associated with brain fog.

    Ageing: While ageing is associated with a natural decline in cognitive abilities, maintaining a healthy lifestyle, including a balanced diet, regular physical exercise, mental stimulation, taking supplements, and adequate sleep, can help mitigate some of the impacts of ageing on brain function.


      The symptoms of brain fog can vary from person to person but commonly include:

      Difficulty concentrating or focusing

      Short-term memory problems

      Confusion or disorientation

      Mental fatigue or feeling mentally "sluggish"

      Difficulty thinking clearly or processing information

      Feeling "out of it" or detached


        Combatting brain fog and enhancing cognitive function requires a multi-faceted approach. Here are some effective strategies:

        Healthy Diet

        Eating a balanced diet rich in nutrients supports brain health. Focus on:

        Omega-3 Fatty Acids: Found in fish, flaxseed, and walnuts, omega-3s are essential for brain health.

        Antioxidants: Berries, dark chocolate, and nuts are rich in antioxidants that protect brain cells from damage.

        Whole Grains: Foods like oats and quinoa provide steady energy for the brain.

          Adequate Sleep

          Ensure you get 7-9 hours of quality sleep per night. Good sleep hygiene practices include maintaining a regular sleep schedule, creating a restful environment, and avoiding screens before bedtime.

          Stress Management

          Practicing stress-reducing techniques such as meditation, yoga, deep breathing exercises, and mindfulness can lower cortisol levels and improve cognitive function.


          Drinking enough water is vital for brain function. Aim for at least 8 glasses of water per day and more if you're physically active.

          Physical Exercise

          Regular physical activity boosts blood flow to the brain, enhancing cognitive performance and reducing stress. Aim for at least 30 minutes of moderate exercise most days of the week.

          Mental Exercise

          Keep your brain active with puzzles, reading, learning new skills, or engaging in stimulating conversations. Cognitive training exercises have been shown to improve mental functions.


          Certain supplements can support cognitive function and reduce brain fog. Here are some with scientific backing:

          B Vitamins: Particularly B6, B9 (folic acid), and B12, which are crucial for brain health and can improve mood and energy levels. In fact, researchers have found that higher intake of B vitamins throughout young adulthood is associated with better cognitive function in midlife.

          Iron: A vital mineral essential for transporting oxygen throughout the body, energy metabolism, DNA synthesis, myelination, and the production of neurotransmitters, all of which support cognitive function and overall brain health. Iron deficiency is one of the most common nutritional deficiencies worldwide and is associated with fatigue and impaired cognitive function. Symptoms can include poor concentration, decreased attention and slower cognitive processing.

          Zinc: An essential trace mineral that plays an important role in many physiological and pathological processes in normal brain development, especially in the development of the central nervous system. It’s, therefore, not surprising, that studies have found that Zinc deficiency can lead to neurodegenerative diseases, mental abnormalities, depression, sleep disorders, tumours, vascular diseases, and other pathological conditions, which can cause cognitive impairment and premature aging.

          Omega-3 Fatty Acids: Studies have shown that omega-3s can improve cognitive function and memory.

          Lion’s Mane: A mushroom, also known as Hericium erinaceus, that contains compounds which are known to stimulate the production of nerve growth. Studies show that Lion's Mane may help protect against neurodegenerative diseases like Alzheimer's and Parkinson's by promoting neural health and function. Furthermore, studies suggest that this mushroom improves memory and cognitive function in healthy individuals or patients with mild cognitive impairment (MCI).

          Bacopa Monnieri: Also called brahmi and water hyssop, a plant that has been used in traditional Ayurvedic medicine for centuries for the treatment of neurological disorders associated with intellectual decline and memory loss, such as AD. In healthy adults, research shows that it enhances brain function, including memory, attention, and the ability to process information.

          Ginseng: One of the most widely consumed herbal products in the world. It has long been used for its apparent medicinal and performance-enhancing properties. Studies suggest that ginseng has potentially beneficial effects on cognition and can improve working memory in adults.

          Ashwagandha: Also known as Withania somnifera, an Ayurvedic plant that has been used medicinally for over 3,000 years. Studies suggest the ashwagandha root improves cognitive health and supports learning, memory and recall.  Research also shows it can reduces stress and anxiety. High levels of which can negatively impact brain function and overall health.

          Ginkgo Biloba: Known for its potential to enhance memory and cognitive speed.

          Rhodiola Rosea: An adaptogen that can reduce fatigue and improve mental performance.

          L-Theanine: An amino acid found naturally in green tea, known for its relaxing properties and its ability to promote mental clarity without causing drowsiness. Studies show, when combined with caffeine, L-theanine enhances cognitive performance more effectively than caffeine alone. This combination can lead to better performance on tasks requiring attention, quick reaction time, and working memory.

          Guarana Seed: Rich in caffeine and provide sustained, stable energy throughout the day, without the crash. Caffeine blocks adenosine receptors in the brain, reducing feelings of tiredness and increasing alertness and concentration. This leads to enhanced cognitive performance, especially in tasks that require sustained attention and quick reaction times. Studies have shown that Guarana can improve memory, reaction time, accuracy of performance and learning abilities.
