What is Brain Fog?

Brain fog is a term often used to describe feelings of confusion, forgetfulness, and general mental fatigue. Whilst there is no formal definition of brain fog, the symptoms are generally described as a temporary and mild cognitive impairment affecting memory, concentration, and motivation.

Brain fog can also be described as mental fog or clouding of consciousness. It’s not a specific medical term but is often a sign or a symptom of another issue. Brain fog is an umbrella term describing a variety of issues, which can include:

  • Lowered ability to think clearly
  • Lowered ability to react and express thoughts
  • Low energy
  • Lack of focus and concentration
  • Memory issues and forgetfulness
  • Feeling confused or disoriented
  • Feeling disorganised or scattered
  • Overall decreased mental performance

Brain fog is often associated with stress, fatigue, and sleep deprivation, but it can also be a symptom of more serious conditions such as depression, anxiety, and autoimmune diseases.

No matter what the cause of your brain fog is, it can negatively affect your day-to-day life, making it difficult to be productive at work, in university or in your free time.

What Causes Brain Fog?

As we mentioned earlier, brain fog can be caused by various things. Some medical conditions that cause inflammation, fatigue or changes in blood glucose levels may cause brain fog. Some examples of medical conditions that have been known to cause brain fog are:

  • Alzheimer’s
  • Anaemia
  • Attention Deficit Hyperactivity Disorder (ADHD)
  • Autoimmune diseases such as arthritis, lupus and multiple sclerosis
  • Chronic fatigue syndrome
  • Depression
  • Diabetes
  • Fibromyalgia
  • Gluten intolerance
  • Hypothyroidism
  • Migraines
  • Sjögren's syndrome

Furthermore, if your brain is tired and overworked, it’s naturally more difficult for you to think clearly and focus. Therefore, brain fog can also be caused by stress, sleep deficiency or insomnia.

Brain fog can also occur during pregnancy or menopause, as big hormone changes can cause forgetfulness, poor focus and cloudy thinking.


Brain fog can also be a side effect of some medications. These include

  • Antihistamines
  • Blood pressure medication
  • Anti-anxiety medication
  • Anti-nausea medication
  • Some sleep aids
  • Chemotherapy

If you aren’t on any medication or don’t suffer from any medical conditions that may cause brain fog, it’s likely that your brain fog is caused by a diet that is lacking in vitamins, minerals and nutrients. This is one of the most common causes of brain fog.

13 Herbs and Vitamins for Brain Fog

1. Vitamin B1

Vitamin B1, also known as thiamine, plays a significant role in reducing brain fog by promoting a healthy connection between the brain and the nervous system. It helps prevent conditions like Cerebellar Syndrome and nerve damage. Furthermore, vitamin B1 supports the development of myelin, a protective sheath around nerves, which improves nerve function and contributes to better concentration, focus, and memory.

2. Vitamin B3

Vitamin B3, also known as niacin, is essential for maintaining proper brain function and cognitive performance. It supports energy production in brain cells and promotes healthy blood flow to the brain. By enhancing brain energy and circulation, vitamin B3 can contribute to mental alertness and clarity, reducing the effects of brain fog.

3. Vitamin B5

Vitamin B5, or pantothenic acid, is involved in energy metabolism and the production of acetylcholine, a neurotransmitter crucial for memory and learning. By supporting energy levels and neurotransmitter function, vitamin B5 can help improve focus, concentration, and mental clarity, thereby reducing brain fog and mental fatigue.

4. Vitamin B6

Vitamin B6, or pyridoxine, is essential for combating brain fog as it facilitates the production of serotonin, a neurotransmitter that enhances mood and mental well-being. Additionally, this vitamin supports the production of hemoglobin, vital for oxygen transport in the blood, thus ensuring proper oxygen supply to the brain. Improved oxygenation leads to enhanced cognitive function and reduced mental fatigue.

5. Vitamin B9

Vitamin B9, also known as folate or folic acid, plays a vital role in brain function and cognitive health. It supports the synthesis of neurotransmitters, including serotonin and dopamine, which are essential for mood regulation and mental clarity. By aiding in the formation of new brain cells and supporting cognitive processes, vitamin B9 can help reduce brain fog and enhance overall mental acuity.

6. Vitamin B12

Vitamin B12, also known as cobalamin, is instrumental in preventing brain fog through its support of nerve and brain development. It aids in the synthesis of neurotransmitters, crucial for efficient neural communication and cognitive processes. By promoting brain health and mental development, vitamin B12 helps maintain a clear and sharp mind, benefiting the overall nervous system.

7. Vitamin D3

Vitamin D3 is an essential ally in the fight against brain fog as it plays a protective role for the brain, immune system, and calcium balance. By regulating key genes involved in brain function, vitamin D3 supports optimal cognitive performance. It also acts as a neurosteroid, nurturing brain development and maintaining neural health. Moreover, vitamin D3 contributes to hormone balance and melatonin production, facilitating healthy sleep patterns and further reducing brain fog symptoms.

8. Iron

Iron is a crucial element for combating brain fog as it facilitates oxygen delivery to brain cells. By improving blood oxygenation, iron enhances cognitive activity and mental clarity. Additionally, iron supports the strength of neural networks, promoting efficient brain function and reducing the occurrence of brain fog.

9. Magnesium

Magnesium is a critical factor in preventing brain fog, as the brain relies heavily on energy derived from this mineral. Supporting nerve transmission, magnesium prevents excessive neuron excitation and helps reduce oxidative stress, both of which can contribute to brain fog. By maintaining optimal magnesium levels, cognitive performance improves, and the risk of brain fog-related issues such as migraines, depression, chronic pain, strokes, and seizures is reduced.

10. Zinc

Zinc contributes significantly to combating brain fog by stimulating the development of neurons in the hippocampus, which is essential for memory and emotions. Proper zinc levels, along with regular exercise and adequate sleep, support overall brain health. Zinc also aids in memory formation and facilitates effective communication between brain cells, promoting mental clarity and preventing brain fog.

11. Ginkgo Biloba

Ginkgo biloba is an herbal supplement known for its potential benefits in brain health. It contains antioxidants that help protect brain cells from oxidative stress, which can contribute to brain fog and cognitive decline. By improving blood flow to the brain and supporting neural health, Gingko biloba may alleviate brain fog symptoms and enhance mental clarity.

12. Matcha Green Tea

Matcha green tea contains L-theanine, an amino acid that can promote relaxation and focus without causing drowsiness. The combination of L-theanine and caffeine in matcha green tea can provide a balanced boost of alertness and concentration. This can help reduce brain fog and mental fatigue, supporting clearer thinking and improved cognitive function.

13. Maca Root

Maca root is an adaptogenic herb that may help reduce stress and fatigue, both of which can contribute to brain fog. By supporting adrenal function and hormonal balance, maca root can enhance energy levels and mental clarity, providing relief from brain fog and supporting overall cognitive performance.
