Supplements: Helpful or Harmful?

About a week ago when a press release about a study published in the Journal of American Academy of Cardiology stated that vitamins and minerals don’t seem to help the health of those people who use them; they should stick to getting nutrients from the food they eat. As you can imagine, I got questions from many readers.

For those of us who use dietary supplements, have we been wasting our money? Or maybe as part of the study showed, we’re doing ourselves harm? Don’t throw out your supplements just yet.

The study was a meta-analysis that examined randomized controlled trials (RCT) since the U.S. Preventive Services Task Force (USPSTF) Recommendations for Dietary Supplements was published in 2012. They examined RCTs that used multivitamins, vitamins and minerals, and antioxidants to determine their affect on health variables related to cardiovascular disease and overall mortality.

Was the study done well? Yes and no. They included RCTs that examined the use of specific supplements and health outcomes. The problem is that they didn’t examine the quality of the supplements used in those studies. That’s a significant problem but not the only one. More on this Saturday. Until then, regardless of the headlines, take your supplements if you know why you’re taking them.

What are you prepared to do today?
