Problèmes des suppléments de ginseng
Five out of 11 ginseng supplements recently selected for testing contained less ginseng than expected from their labels or were contaminated with lead and/or pesticides, according to a report from ConsumerLab.com, White Plains, NY.
ConsumerLab.com has reported problems with the quality of ginseng supplements since 2000. Ginseng is a popular herb with U.S. sales last year of $83 million according to Nutrition Business Journal.
“Consumers need to be wary of the quality of ginseng supplements,” said Tod Cooperman, MD, president of ConsumerLab.com. “People should also recognize that there is enormous variation in the amount of ginsenosides—key ginseng compounds—in marketed supplements. We found most products to provide approximately 10 to 40 mg of ginsenosides per day, but some yielded much higher amounts, including one that delivered a whopping 304 mg. We are not aware of human studies with the higher amounts. The effects might certainly differ from one product to another.”
