The most recent cover story in the September 2010 issue of Consumer Reports, entitled The 12 Most Dangerous Supplements, generated a firestorm of comments and controversy all over the MSM and the Internets, albeit at the tail end of what's usually a very slow news month in the middle of the summer.

If you're one of the growing number of folks who have subscribed to our daily health blog over the past few months, however, I wouldn't be surprised if you thought you'd already heard about some of these very same problems before. Fact is, you probably have…

A few months ago in this space, we discussed Reader's Digest's "crash-course" on vitamin safety, 5 Vitamin Truths and Lies. Unlike the aforementioned piece that clocked in at just under 1,500 words, Consumers Digest devoted eight full pages to supplements, providing guidance on a variety of topics.

Even though the Consumers Digest article was very thorough and detailed, I'm not sure how much more you'd learn about supplements that you already have, if you've been following our blog, even for a little while. Arguably, if you've been doing your homework, you may already have a pretty good understanding about what it takes to choose the right supplement for your health.

But this may be your first time reading our 14-month old health blog, or, perhaps, you're just getting around to looking. No matter… We've done the work for you. What follows are six detailed questions you should be asking every time you consider taking a supplement:

1. Has the supplement you're considering ever failed a quality test by an independent source, like ConsumerLab.com?

2. Has the company producing the supplement ever been the target of a regulatory agency like the FDA or FTC?

3. Does the product label of the supplement you're considering include testing data that guarantees its authenticity, purity and potency?

4. Is the strength and amount of each ingredient listed prominently in the Supplement Facts box?

5. Can you find a readable lot number and expiration date on the product label?

6. Have you discussed taking this supplement with your doctor first to prevent any unforeseen drug or food interactions?

In addition, to help you get moving in the right direction, you'll want to review CNCA’s Nutritional Supplement Quality -- The Facts and watch this five-minute video interview with Dr. Timothy Birdsall, vice chairman of CNCA's Quality Control Unit, who explains just how easy it is to find a contaminated supplement and recommends which supplements everyone should consider taking.
