Milk thistle extract has long been valued for its role in ensuring healthy liver function.56-65 This extract consists of silibinins and other similar compounds. Until recently, researchers believed silibinins were the most biologically active ingredient in milk thistle extract. Highly advanced extraction technology has now enabled scientists to isolate silymarin constituents and 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.66 Certified European Milk Thistle is the first milk thistle extract to contain standardized, premium-quality potencies of silymarin, silibinins, isosilybin A and isosilybin B, providing the full spectrum of milk thistle compounds that promote a healthy liver and prostate.61-73 The botanical extract in Certified European Milk Thistle is a triple standardized milk thistle extract. In addition to an optimal 80% stan-dardization of the main active compounds, silymarin flavonolignans, this formula is further standardized to three highly active isomers — silibinins and isosilybin A and B. |
