Boost Your Mental Clarity: Essential Vitamins for Banishing Brain Fog

Do you often find yourself struggling with brain fog? That feeling of mental cloudiness, forgetfulness, and difficulty concentrating can be frustrating. There is no magic pill to clear away brain fog, but incorporating certain vitamins into your diet may help support cognitive function and promote mental clarity. In this article, we’ll provide some clarity by exploring the vitamins associated with brain health and how to include them in your daily diet.

Vitamins that help boost Brain Health

Vitamin B12

B12 is the brain’s best friend, it is crucial for proper brain function and overall cognitive health. It is involved in the synthesis of neurotransmitters, the production of myelin (the protective sheath around nerves), and the formation of red blood cells, which carry oxygen to the brain. Deficiency in vitamin B12 has been linked to cognitive impairment, memory problems, and difficulty concentrating, often associated with brain fog.
Food sources: mainly animal products like meat, fish, eggs, and dairy, veggies and vegans can include nutritional yeast, fortified spreads and plant milks but to reach required levels, it’s worth supplementing.
Our Pink Grapefruit B12 drink contains 200% of your daily dose of B12.

Vitamin D

Low levels have been linked to cognitive impairment and mood disorders. Vitamin D receptors are found throughout the brain, including areas associated with memory and learning. It is thought to influence cognitive function in several ways – it regulates calcium balance which supports the health of brain cells, and has anti-inflammatory and antioxidant properties, which may protect cells from damage and reduce cognitive decline.
Food sources: sunlight is the best source of vitamin D, it’s also found in fatty fish, egg yolks, meat, mushrooms, fortified dairy products and cereals. In the UK we are advised to supplement with 10mcg per day.
Our best-selling Mango & Passionfruit Vitamin D drink contains 10mcg of vitamin D in just one bottle. 

Omega-3 Fatty Acids

Omega-3 Fatty Acids particularly EPA and DHA, are essential for brain health. These fatty acids are critical components of cell membranes in the brain and play a vital role in cognitive function. Research suggests that omega-3 fatty acids support optimal brain health, enhance memory, and reduce the risk of age-related cognitive decline and disease. They are also linked to improved mood, attention, and overall mental well-being.
Food sources: oily fish - salmon, mackerel and sardines, walnuts, chia seeds, and flaxseeds.

Vitamin E 

Vitamin E is a powerful antioxidant for brain function and cognitive health. Vitamin E's antioxidant properties help neutralise ‘free radicals’, reduce inflammation, and maintain cell membranes. This helps protect brain cells from oxidative stress, which can contribute to cognitive decline and neurodegenerative disorders. Vitamin E has also been associated with a reduced risk of Alzheimer's disease and other forms of dementia.
Food sources: nuts, seeds, spinach, and broccoli.


Magnesium is a vital mineral involved in hundreds of biochemical reactions in the body, including brain function. It helps regulate communication between brain cells and may improve cognitive performance. It has also been shown to promote ‘neuroplasticity’, the brain's ability to adapt and form new connections, crucial for learning and memory formation. It is also helpful for managing stress, relaxation, and sleep, which can indirectly improve brain health.
Food sources: leafy green veg, legumes, whole grains, almonds and dark chocolate.

 Take home message 

While incorporating these brain boosting nutrients into your diet can support brain health, don’t forget the basics - stress, lack of sleep and dehydration may all be contributing to brain fog. Exercise, stress management, and working on sleep quality can also improve mental clarity. If you have ongoing concerns always consult with a healthcare professional.
