What’s in Those Supplements?

We have no idea what is in the supplements we buy. All because of the stupidity of our Congress passing the Dietary Supplement Health and Education Act of 1994 (DSHEA): (DSHEA) defined dietary supplements as a category of food, which put them under different regulations than drugs. They are considered safe until proven otherwise. Caveat Emptor.

The New York State attorney general’s office accused four national retailers on Monday of selling dietary supplements that were fraudulent and in many cases contaminated with unlisted ingredients.

The authorities said they had run tests on popular store brands of herbal supplements at the retailers — Walmart, Walgreens, Target and GNC — which showed that roughly four out of five of the products contained none of the herbs listed on their labels. In many cases, the authorities said, the supplements contained little more than cheap fillers like rice and house plants, or substances that could be hazardous to people with food allergies.

At GNC, for example, the agency found that five out of six samples from the company’s signature “Herbal Plus” brand of supplements “were either unrecognizable or a substance other than what they claimed to be.” In pills labeled ginkgo biloba, the agency found only rice, asparagus and spruce, an ornamental plant commonly used for Christmas decorations.
