What is Silybin?

Silybin (also known as silibinin) is the primary bioactive component of Milk Thistle extract (Silybum marianum). It is not the whole extract, but rather the most potent and studied molecule within a complex called silymarin.

Identity: Silybin is a flavolignan—a unique compound combining a flavonoid and a lignan structure. It is the major and most active constituent of silymarin, which is the standardized extract of milk thistle seeds (typically 70-80% flavonolignans, with silybin A & B making up about 50-70% of that).

Key Point: "Milk Thistle Extract" is often standardized to 70-80% silymarin. Silybin is a purified, more potent component within silymarin. High-quality supplements may offer silybin phytosome or silybin complexed with phospholipids, which dramatically increase its bioavailability (by up to 10x).

Milk thistle extract is a well-known herbal supplement with a long history of use, primarily for supporting liver health and function through its active compound, silymarin.
