Vitamin B12 deficiency: THESE common medications are the hidden cause, top doc says

A top Indian neurologist warns that common medications like Metformin and proton pump inhibitors (PPIs) can silently deplete Vitamin B12 levels. This deficiency, if unchecked, can lead to severe neurological damage. Individuals on these drugs long-term, especially older adults and vegetarians, are at higher risk. Regular B12 testing is advised.
