A possible side-effect of heartburn medications
A lot of people who suffer from heartburn take what's called a proton pump inhibitor or PPI. Prilosec and Nexium are two popular brands.
PPIs work really well, but a large study in the Journal of the American Medical Association found that they can interfere with your body's ability to absorb vitamin B12.
"People who regularly took these proton pump inhibitors had lower vviamin B12 levels, sometimes seriously lower levels," said Dr. John Swartzberg, head of the editorial board at the UC Berkeley Wellness Letter.
His advice: If you have to take these drugs regularly, make certain your doctor knows and have your vitamin B12 level checked to be sure it's OK.
"The other thing to remember is that the liver can store vitamin B12 for several years, so it may take several years for your vitamin B12 level to drop. But you don't want to be in that position because vitamin B12 is necessary for our bodies to work," Dr. Swartzberg said.
