Well, you’re not crazy. It may not come as a surprise to many of you, that a recent study conducted by the New York attorney general’s office, has found that some store brand supplements don’t supplement much of anything. In fact, the study found that 79 percent of the brands tested, did not contain the herbs labeled on the bottle.
Walmart’s “Spring Valley” supplements: ginkgo biloba, St. John’s wort, ginseng, garlic, echinacea, saw palmetto were tested. Walmart had the worst results: of 90 DNA tests on 18 bottles, only 4% found any DNA from the labeled ingredient.
Huh. I'm so surprised.
