Causes of Vitamin B12 Deficiency
Most commonly caused by inadequate dietary intake in strict vegetarians and vegans, since B12 occurs naturally only in animal-derived foods. Malabsorption due to conditions like pernicious anaemia, gastric surgery, or chronic use of medications such as metformin and proton pump inhibitors can also impair B12 absorption even with adequate intake. Ageing reduces stomach acid production, which further impairs the body's ability to absorb B12 from food.
