The Active Ingredient Is: Milk Thistle (Silybum marianum) Extract

Milk thistle seed extract, often standardised to contain silymarin, is a herbal supplement used for its antioxidant properties and potential support for liver function. This form is typically provided as a concentrated extract from milk thistle seeds.

Form is rapid-release softgels containing the extract for convenient daily use; source material is the milk thistle plant (Silybum marianum).

What Does Milk Thistle Do?

Milk thistle is involved in supporting normal liver function and antioxidant activity as suggested by clinical context and regulatory guidance. Research indicates potential improvements in liver enzyme measures in some populations, reflecting its role in metabolic and detoxification processes.

Dr. Saller of the University of Freiburg found that silymarin may contribute to liver function support in certain individuals, aligning with EFSA-style interpretations for ordinary nutrition.
