ConsumerLab tests milk thistle supplements

consumer-labMilk thistle is sometimes taken as a natural treatment for liver problems.

Unfortunately, most milk thistle supplements contain less than the labeled amount of silymarin.

Unfortunately, average consumers are wasting their money on milk thistle products that mislead about their contents.
