What Is Vitamin B12?
If you’re like most people, you probably don’t think about vitamin B12 much. But this essential nutrient plays a vital role in keeping your body and brain healthy.
B12 is a water-soluble vitamin that’s found in animal-based foods such as meat, poultry, fish, and eggs. It’s also available in supplement form.
B12 is important for many functions in your body, including the formation of red blood cells, the maintenance of your nervous system, and the production of DNA.
A lack of B12 can lead to a condition called pernicious anemia, which can cause fatigue, weakness, and other symptoms.
B12 deficiency can also cause cognitive problems such as memory loss and brain fog.
If you think you might be deficient in B12, talk to your doctor. They can order a blood test to check your levels.
If you are deficient, they may recommend supplements or shots.
Causes of B12 Deficiency
One of the most common causes of vitamin B12 deficiency is pernicious anemia which is an autoimmune disorder that destroys the stomach lining.
This lining is necessary for the absorption of vitamin B12.
Vitamin B12 deficiency is also common in:
- Vegans or vegetarians who don’t eat foods that are fortified with vitamin B12.
- People with gastrointestinal disorders like Crohn’s disease or celiac disease.
- People who have had surgery to remove part of the stomach or intestine.
- Older adults.

Mental Symptoms of Vitamin B12 Deficiency
If you’re feeling forgetful, having trouble concentrating, or just generally feeling mentally foggy, you could be experiencing symptoms of a vitamin B12 deficiency.
Though vitamin B12 is found naturally in animal products like meat and eggs, many people don’t get enough of it in their diets. This can lead to a host of problems, including brain fog.
Brain fog can be a frustrating symptom of a vitamin B12 deficiency. You might feel like you can’t think clearly or that your memory is slipping.
Thankfully, vitamin B12 supplements can help to clear up brain fog and improve your overall cognitive function.
Can B12 Deficiency Cause Brain Fog?
While there can be many causes of brain fog, one potential cause is vitamin B12 deficiency.
Vitamin B12 is a nutrient that’s essential for proper brain function. It helps to produce the myelin sheath that protects nerve cells, and it’s also involved in the synthesis of neurotransmitters like serotonin and dopamine.
A lack of vitamin B12 can therefore lead to cognitive problems like brain fog.
