What Is Silymarin Extract Powder?
Silymarin Extract Powder is a concentrated botanical ingredient derived from milk thistle, a flowering plant in the Asteraceae family. The plant is native to the Mediterranean region and is also widely known as milk thistle, Mary thistle, blessed milk thistle, or Saint Mary’s thistle. Because of its long history in traditional herbal use and its well-recognized active compounds, Silymarin Extract Powder has become a widely used raw material in dietary supplements, functional foods, pharmaceutical formulations, and nutraceutical products.
Milk thistle is identified by its distinctive leaves, which are marked with white mottling and contain a milky sap. The extract is typically obtained from the seed, where the major bioactive flavonolignans are concentrated. For manufacturers, formulators, and bulk buyers, Silymarin Extract Powder is valued for its standardized composition, technical versatility, and broad market demand in health-focused product development.
