Milk thistle consists of three potent liver protective flavonoids: silybin, silydianin and silychristin.* Collectively these are known as silymarin. To be effective, milk thistle products must be standardized to contain this active blend. Kirkman’s milk thistle is standardized to contain 80% silymarin. Recent research has indicated that silymarin helps to protect against the depletion of glutathione in liver cells.*
