What’s the Issue with the Milk Thistle Products?
Independent lab tests have shown that these three Costco products do not contain enough of the active ingredient silymarin needed to live up to their advertised claims. Some of the supplements advertise that they contain the “standardized amount” of silymarin – the amount established by the herbal supplement industry to help guarantee the effectiveness of a product – but contain far less when tested.
Essentially, these lab tests have shown that the amount of silymarin contained in the supplements is too low and therefore renders the products useless. As a result, attorneys believe the products’ labels are misleading in that they don’t live up to their advertised claims about liver health and do not meet the minimum amount of silymarin required to advertise a product as containing the “standardized extract.”
