Vitamin B12

Why Does a Vitamin B12 Deficiency Occur?

 Vitamin B12 deficiency often results from low intake, especially in vegans and vegetarians, as B12 is mainly in animal products. Malabsorption issues, such as pernicious anemia or Crohn’s disease, also prevent proper absorption. Aging can reduce intrinsic factor production, essential for B12 absorption, and certain medications like proton pump inhibitors and metformin can further interfere with absorption.

What to Do About Vitamin B12 Deficiency?

Increase B12 intake through dietary sources like meat, fish, dairy, and eggs. For those unable to absorb B12 effectively, supplementation in the form of oral tablets or injections may be necessary. Addressing underlying health conditions that impact B12 absorption is also crucial for managing deficiency effectively.
