ALBANY, N.Y. — Bottles of Walmart-brand echinacea, an herb said to ward off colds, were found to contain no echinacea at all. GNC-brand bottles of St. John’s wort, touted as a cure for depression, held rice, garlic and a tropical houseplant, but not a trace of the herb.
In fact, DNA testing on hundreds of bottles of store-brand herbal supplements sold as treatments for everything from memory loss to prostate trouble found that four out of five contained none of the herbs on the label. Instead, they were packed with cheap fillers such as wheat, rice, beans or houseplants.
Analysis finds most brands contain only 68% of fatty acid amounts listed on label
Nearly all fish oil supplements marketed in New Zealand contain much less of the brain-boosting omega-3 fatty acids than their labels claim, an eye-opening study has found.
When researchers at the University of Auckland’s Liggins Institute tested 36 different brands of fish oil capsules, just three contained the same concentrations of omega-3 fatty acids as listed on the label.
They found that over half had oxidised to a level higher than the recommended limit – and this had nothing to do with the best-before date, price, or country they came from.
