Vitamin B12 is probably one of the most known and studied of vitamins. It is a powerhouse vitamin and it works with folate to help produce and maintain the myelin surrounding nerve cells. It also helps with mental ability, red blood cell formation, and the breakdown of some fatty acids and amino acids to produce energy.

There are only two ways you can obtain B12. By eating foods that are rich in B12, such as meat, poultry and milk products, or you must obtain it from a supplement. Unlike other B vitamins, deficiencies are common, particularly in vegans and older adults, since B12 is most commonly found in animal products. It is also available in soy products, fortified foods and nutritional yeast. Deficiency symptoms include anemia, fatigue, weakness, depression, confusion, dementia, [poor memory](https://myvillagegreen.com/blogs/post/4-foods-that-fight-memory-loss), constipation, loss of appetite, weight loss, numbness and tingling in hands/feet, balance issues, and soreness of the mouth and tongue.

## Reasons to take vitamin B12

### 1\. Vegetarian/vegan

Most omnivores get all the B12 we need from animal foods: red meat, fish and dairy products. However, little or no B12 is found in plant-based foods. Although vitamin B12 deficiency is fairly rare in healthy adults, it is common in strict vegetarians who eat no animal products. In these cases, [taking a supplement would be beneficial.](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5188422/)

### 2\. Gastrointestinal problems

Deficiency can also be a problem for those who suffer with digestive system disorders, such as chronic gastric reflux, that limit the absorption of the nutrient, and in elderly people whose stomach acid production has dropped. That’s because B12 is absorbed into the body when hydrochloric acid in the stomach breaks down the protein and combines with a substance called intrinsic factor so the nutrient can be absorbed through the digestive tract.

### 3\. Boosts brain power

Sometimes the only symptom of B12 deficiency is a barely noticeable decrease in cognitive function. Over time, if the deficiency is not reversed, anemia and dementia that looks very similar to Alzheimer’s disease can develop.

A simple blood test for B12 level is essential, especially in someone who is elderly and in whom memory loss has been noticed. For all of those people, [B12 supplementation is crucial.](https://www.mayoclinic.org/diseases-conditions/alzheimers-disease/expert-answers/alzheimers/faq-20057895#:~:text=Vitamin%20B%2D12%20helps%20maintain,supplements%20can%20help%20improve%20memory.) Memory loss that is attributed to deficiency of B12 will often significantly improve or even reverse the condition, when supplementation is introduced.

B12 may also help with depression. Studies have demonstrated a benefit of supplementation with vitamin B12 alongside antidepressants in patients with low-normal B12 levels and depression.
