Application / Intended Use
Silymarin is standardised to 80% flavonolignans by UV and formulated into liver-support supplements, typically at 140-420 mg daily in divided doses. It is also used in veterinary hepatoprotective products and, at lower inclusion, in functional beverages. Poor water solubility means it is usually delivered in capsules or as a phospholipid complex.
