There are a few possible explanations for brain fog. One possibility is that you’re not getting enough essential fatty acids, specifically the omega-3 fatty acids found in fish oil.
A lack of these fatty acids can lead to inflammation, which has been linked with cognitive decline and other brain health problems. Another possibility is that you’re not getting enough quality sleep, which can also impact cognitive function.
Brain fog can also be a symptom of nutrient deficiencies, such as low levels of iron or vitamin B12. If you think you might be experiencing brain fog, it’s worth checking with your doctor to see if there might be an underlying cause that can be addressed.
