Milk thistle extract has long been valued for its role in ensuring healthy liver function.* Milk thistle extract consists of silibinin and other similar compounds. Until recently, researchers believed that silibinin was the most biologically active ingredient found in milk thistle extract. Highly advanced extraction technology has now enabled scientists to isolate silymarin constituents and to test their efficacy against various cell lines. Among the compounds tested, a silymarin constituent called isosilybin B proved to be the most efficient in maintaining healthy cell division.1*

New Mega Silymarin with Isosilybin B is the first milk thistle extract to contain standardized, pharmaceutical grade potencies of silymarin, silibinin and isosilybin B - providing the full spectrum of milk thistle's liver and prostate protective compounds.
