Are you among the 50% of Americans who suffer from acid reflux (aka gastroesophageal reflux disease (GERD) or peptic ulcer disease)? If so, chances are you’ve taken a proton pump inhibitor (PPI) like Prilosec to put an end to the heartburn, wheezing, and tightness in your throat. These drugs act like Band-aids to soothe gastrointestinal upset, but a recent study links long-term use of PPIs to vitamin B12 deficiency…a condition with serious consequences that outweigh any perceived benefit.
