Milk thistle is composed of three strong liver-safeguarding flavonoids: silybin, silydianin and silychristin - collectively referred to as silymarin. In order to appear effective, milk thistle supplements must be standardized to include this powerful mix. Kirkman's Milk Thistle is specifically standardized to 80% silymarin, based on current research that suggests silymarin also helps protect liver cells from the loss of glutathione.
