(CBS) - A Kaiser Permanente study of 200,000 patients is linking popular heartburn prescriptions with vitamin B12 deficiency.
The medications are known as Proton Pump Inhibitors and Histamine 2 receptor antagonists.
Researchers found people who took them for more than two years were more likely to have low levels of vitamin B12.
The authors say this is not definitive proof the drugs cause the deficiency and people should not stop taking them.
But doctors may want to consider lowering dosages.
B-12 deficiencies can lead to dementia, neurological damage and anemia.
