Tune in to our radio show on your local public radio station, or sign up for the podcast and listen at your leisure. Here's what it's about:

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. Turmeric has been one of the favorites, partly because there is some evidence that it may be helpful. But just how good is your turmeric supplement? We find out from ConsumerLab.com.   

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.

Call in your questions and comments at 888-472-3366 or email radio@peoplespharmacy.com between 7 and 8 am EDT.

Does cocoa powder contain a sufficient amount of flavonoids to be effective? After reading about the health affects of chocolate I have been putting a heaping spoon full of cocoa in my coffee in the morning. It gives the coffee a great chocolate flavor and I don't add any of the extra calories found in chocolate.

I've been taking a vitamin and mineral supplements for four decades and even though I can't point to any specific advantage I might have had from this practice, I can at least say that other than having to wear glasses, I function pretty much the same as I did in my 20s.

I take pains to seek out quality supplements that I take on a regular basis in addition to a healthy diet and lifestyle. And I am fully aware that I may in fact have "expensive pee" to some extent, but I don't really care because I'd rather have the nutrients and not need them than need the nutrients and not have them.

I don't understand why Centrum Silver was used in a study of supplements. They should have used real supplements, not the mashed condensed form that fits into one pill. That's ridiculous!

I was without health insurance for a number of years and I would have been in much poorer health without the E, A, niacin (I take it 4 times a day to control arthritis pain in my hands), C, and a number of others. I might add that my doctor is very much in favor of these supplements and checks with me at every appointment to make sure I'm still taking everything, especially my calcium and D3.

Dear Terry and Joe,

I love your show!! Please keep up the great work.

I was, however, quite disappointed that your need for a 'break' prompted you to interrupt (mid-sentence!) the herbalist who called, as she was providing some truly excellent information. Upon returning after the break, you moved forward with no reference to this caller.

I guess that's understandable, but I was disappointed. I would have liked to hear how she would have completed her sentence (if allowed to do so), and how she would have completed her thought process, in terms of her advice to listeners, based on her experience.

Maybe that caller will post here, with some additional information.

best,
Jen

PEOPLE'S PHARMACY RESPONSE:

Jen,

We always feel terrible when we have to cut off a caller. Sadly, though, our breaks are not modifiable on a live show. If we do not stop promptly, the computerized automation takes over and all our public radio listeners would hear a very disorienting transition that would not make any sense. So, rude as it sounded, we really did have to say goodbye. Perhaps she will call in another time and share more information.

So sorry that we are so constrained by the clock.

I suffer from neuropathy, was informed by neurologist it is due to B-12 deficiency, I have taken Prevacid or others for years for GERD. Now having B-12 injections and OTC B-12 and have stopped the Prevacid, etc. I was never told about the ill effects of these drugs. Don't know if things will improve with the neuropathy problem.

Why would a clinical trial that is designed to fail do anything as sensible as using genuine testing controls? ALL of the so-called clinical trials sponsored by the AMA, pharmaceutical manufacturers, or the FDA fall into the same category. They are contrived to validate a preconceived "fact".
