What is milk thistle press cake, and why is it included in this fiber blend? — Siberian Fiber with Milk Thistle 170g

A press cake is the solid material left after seeds are pressed for oil. In this product, milk thistle press cake is the distinctive component that contributes extra plant matter alongside its characteristic phytonutrients. Milk thistle has a long tradition in herbal practice, especially in formulas aimed at liver function and fat metabolism. Its best-known compounds are flavonolignans grouped under the name silymarin. The product information describes these substances as having antioxidant action.

Because of this tradition, milk thistle is often included in digestive and liver-focused supplements for people whose menu is rich, irregular or low in plant foods. In this blend, it is not the main fiber source — wheat bran provides the primary insoluble fiber fraction — but it adds a different type of plant material and gives the product its distinctive character.

If you are considering this product because of the milk thistle component, remember that it is a food supplement, not a medicine. It is not a substitute for a balanced diet. If you have a liver condition, take medication regularly, or are pregnant or breastfeeding, it is sensible to check with a specialist before use.
