Silymarin is a key active complex extracted from ripe seeds of Milk Thistle (Silybum marianum). For decades, milk thistle extract has remained one of the most popular herbal raw materials for liver support products all over the world. Our silymarin powder is produced using low-temperature ethanol extraction and refined purification technology. The process effectively extracts flavonolignan compounds while removing unwanted fiber, impurities and residual substances.

Many low-grade milk thistle powders contain large amounts of plant residue and unstable active levels. Our standardized silymarin features consistent content, good flowability and uniform color. It is widely chosen by manufacturers of dietary supplements and natural skincare lines. All milk thistle seeds are carefully screened to remove broken, moldy and deteriorated raw materials. No artificial pigments, preservatives or unnecessary fillers are added during the whole production workflow.
