The Main Ingredient Is: Milk Thistle (Silymarin)

Milk thistle is a herb whose seeds hold silymarin, a bunch of flavonolignans praised for antioxidant action. This blend fuses milk thistle seed extract with seed powder for a balanced herbal profile.

This form is derived from milk thistle seeds and is used to help the liver’s normal detoxification processes and antioxidant defences.

What Does Milk Thistle Do?

Milk thistle helps support liver function and detoxification through its antioxidant properties, as described in clinical assessments of silymarin use for liver health. This mechanism aligns with EFSA and NHS understandings of antioxidant support in the liver.

Dr. Rambaldi of the University of Bologna found that silymarin supplementation can help modulate liver enzymes in studies evaluating liver health, contributing to membrane stability and cellular antioxidant protection.
