Who is most at risk of vitamin B12 deficiency

Vitamin B12 deficiency occurs mainly in people who follow a vegetarian diet without consuming cow's milk and dairy products, the elderly and in cases of gastrointestinal surgeries, Crohn's disease, celiac disease and pernicious anemia.

In addition, the use of medications such as antibiotics, metformin, and remedies for gastritis and gastric ulcers, such as Omeprazole, may decrease the absorption of B12 in the gut, and so it is recommended that you talk to your doctor about the need to use vitamin supplements.
