4 Causes of Vitamin B12 Deficiency
Diet
Vitamin B12 can be found naturally in many foods. Thus, an unbalanced diet without some B12-rich foods, such as meat, eggs, or dairy, would lead to vitamin B12 deficiency. In addition, people with a vegetarian diet would also be at a higher risk of developing this health issue. In some cases, your body cannot absorb vitamin B12 from some foods that you eat. Thus, it is better to consult your doctor and plan a suitable diet. [7]
