Milk thistle extract

Milk thistle extract (CAS 84604-20-6), derived from Silybum marianum, is a standardized botanical extract concentrated in silymarin flavonolignans. It functions as a plant-based antioxidant active across nutraceutical, pharmaceutical, and cosmetic formulations. Buyers typically source it against defined silymarin content, making standardization the primary procurement specification. In dietary supplements and functional foods, it is formulated into capsules, softgels, and tablets targeting liver support positioning.

This extract represents one of the highest-volume botanical supplement categories globally. Pharmaceutical manufacturers use silymarin-standardized grades as an intermediate in hepatoprotective drug formulations, particularly in European and Asian markets. In these regions, liver-related indications are formally approved for medical use. In cosmetics and personal care, it is incorporated into anti-aging serums, facial creams, and scalp treatments where antioxidant actives are required.

These formulations protect against oxidative stress in the formulation matrix. Sports nutrition and wellness brands also use it in detox and cleanse product lines as a label-active botanical ingredient for health-conscious consumers. Milk thistle extract is supplied as a fine powder, typically standardized to 70%, 80%, or 95% silymarin content by HPLC. Food-grade and USP-grade specifications are available for supplement and pharmaceutical applications.

Bulk supply is standard in kilogram to metric ton quantities to meet industrial demand. Water-soluble and oil-dispersible variants are available for specific formulation needs across various delivery systems.
