Vitamin B12

Why Vitamin B12 Deficiency Occurs?

Vitamin B12 deficiency often arises due to inadequate dietary intake, particularly in those following a vegan or vegetarian diet, as B12 is primarily found in animal products. Malabsorption issues, such as those caused by pernicious anemia or gastrointestinal disorders like Crohn's disease, can also prevent proper absorption. 

Aging can diminish the stomach's ability to produce intrinsic factor, a protein essential for B12 absorption. Certain medications, like proton pump inhibitors and metformin, can further interfere with B12 absorption, exacerbating deficiency risks.

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.
