What is brain fog?

According to CNET, brain fog is the general feeling of sluggishness, and an inability to concentrate or focus. It is usually accompanied by deep feelings of fatigue and could become extremely challenging if not resolved. Brain fog isn’t exactly a medical condition but experts believe it results from neuroinflammation which can be caused by a wide range of reasons.

Brain fog can be caused by poor sleep, drug use or withdrawal, stress or jet lag. It can even be a side effect of some prescribed medication.

Vitamin D

Per Healthline, Vitamin D is crucial for many aspects of health including brain function. Some research has found that a lack of vitamin D can also be a risk factor for depression, a symptom of which is the dreaded brain fog. The best source of vitamin D is the sun, but for many people it is not feasible to get enough sunshine throughout the day so it is recommended to take a vitamin D supplement.


Iron is the most important building block for the formation of healthy red blood cells. It is also involved in cognitive function as some research found that too high or too low of iron concentrations in the blood has a disruptive effect on the nervous system.

Vitamin B12

B12 is also a very important tool to make blood cells, however nerves rely on it as well to ensure healthy development. A consistent B12 deficiency can result in the production of faulty red cells which limit the distribution of oxygen to the body thereby creating symptoms that mimic brain fog such as weakness and fatigue, according to RUSH.

The best way to combat brain fog is to ensure a balanced diet, making sure to exercise frequently, reduce the consumption of caffeine, alcohol and tobacco, and most importantly ensuring adequate sleep.
