Low levels of vitamin B12 can cause different health issues

Vitamin B12 or cobalamin is a water-soluble nutrient, found primarily in animal foods. By water-soluble, it means that the vitamin can dissolve in water and travel through the bloodstream. Surprisingly, the body can store vitamin B12 for up to 4 years, however, one can still be deficient of it at some point in life.

It is one of the most important nutrients that our body needs for several functions like forming red blood cells and DNA. It also plays a significant role in the development of brain and nerve cells.

What is vitamin B12 deficiency?

Although vitamin B12 is found in many animal products and one can get enough of it through supplements, B12 insufficiency or deficiency is a common problem among people. This can either be due to reduced intake of foods that contain the B vitamin or due to certain health conditions including pernicious anemia, gastrointestinal issues such as peptic ulcer disease, gastrinoma or Zollinger-Ellison syndrome and certain drugs that negatively impact the absorption of vitamin B12.
