Costco Milk Thistle Supplement Products Class Action

Among its many vitamins, minerals, and other supplements, Costco sells two supplements containing milk thistle, Trunature Milk Thistle and Trunature Liver Health Complex. This class action alleges that Costco cut corners in its manufacturing of the products, so that the supplements contain far less of the main ingredient of milk thistle than the labels advertise.

This class action proposes two classes. The nationwide class is made up of all persons in the US who purchased the products; the New York subclass is all persons in the state of New York who purchased the products.

Many people buy milk thistle products as a natural treatment for gallbladder problems or for liver problems such as cirrhosis, jaundice, or hepatitis. The main active ingredient in milk thistle is silymarin.

However, according to the complaint, Costco and other companies cut corners in manufacturing supplements, in order to keep costs low, so that supplements often don’t contain as much as they claim of the substances advertised on the labels.

The complaint contains photographs of the labels of the Costco products. In the photo of Trunature Liver Health Complex, the label claims that two tablets (one serving) of the complex contain “Milk Thistle (Silybum marianum) extract (seed) 500 mg (standardized for 80% [400 mg] silymarin).” Similarly, in the photo of Trunature Milk Thistle, the label claims that one softgel (one serving) of Trunature MT contains “Milk Thistle Extract (Silybum marianum) (seed) 200 mg (standardized to 80% [160 mg] silymarin).”

However, according to the complaint, an independent laboratory analysis of the two products shows far less silymarin. The complaint says that Trunature Liver Health Complex contained 203 mg silymarins per serving, just slightly more than half of the promised amount of silymarin and less than half of the promised amount of the extract. In the case of Trunature Milk Thistle, it says, one serving contained only 83.4 mg silymarins, just slightly more than half of the promised amount of silymarin and less than half of the promised amount of the extract.

Furthermore, the complaint alleges, there is little scientific support for the use of milk thistle in treating liver and gallbladder problems. The complaint claims that Costco’s low doses makes it unlikely that the products will have the effect that the purchaser is hoping for.

The complaint therefore alleges that Costco, in representing that the products to contain more of the active ingredient than they actually do, has violated New York’s general business law as well as breaches of express and implied warranty.
