New research suggests that multivitamins are not beneficial against heart disease or dementia. But though some doctors are saying vitamins are a waste of money, sometimes people really need to pay attention to possible vitamin deficiencies.
The hugely popular acid-suppressing drugs such as omeprazole (Prilosec), lansoprazole (Prevacid) or esomeprazole (Nexium) have long been know to interfere with vitamin B12 absorption. But doctors don’t often test patients taking such PPIs (proton pump inhibitors) for vitamin B12 status, perhaps because this complication is unlikely. New research from Kaiser Permanente demonstrates that it is not as uncommon as it has been thought.
Lots of people are looking to natural supplements instead of drugs for relief from joint pain or possible protection from cognitive decline.

There are brand new guidelines for treating blood pressure. How might they affect your treatment? We talk with Dr. Sidney Smith about the guidelines and how they are being received.
Cancer screening seems like such a good idea: isn’t an ounce of prevention supposed to be worth a pound of cure? Yet as screening technologies become more and more sensitive, they may pick up tumors that don’t require treatment. What do doctors and patients do? Listen to Dr. Ned Patz, the lead author of a new study on lung cancer screening published in JAMA Internal Medicine, explain the problem.
