Active ingredient
Milk thistle (Silybum marianum MZ 80)

Each capsule contains extract equivalent to dry:  

Specific extract of Silybum marianum (Milk thistle) (MZ 80) 180 mg equiv. to dry fruit 7.2 g standardised
to silymarin 140 mg


Medicines containing naturally sourced active ingredients like Silybum marianum can vary considerably depending on the species of plant chosen, the way it’s grown and harvested, and the extraction and production process. So it is essential to ensure the final product you get is the same as the one researched in clinical trials.

In Legalon, care is taken to use the same specific extract of Milk thistle, known as MZ 80,  made using a patented production process and researched in clinical studies to support healthy liver function.1-8 

That’s why you can feel confident that Legalon can offer the same benefits and tolerability as demonstrated in the clinical studies.

There are no known reported interactions between Legalon and other medications. As always it is  recommended  that you talk to your healthcare professional if you have any questions about using Legalon.
