A well-researched form of milk thistle that supports liver function* Siliphos combines a flavonoid from milk thistle (silybin) with phospholipids to support liver health and glutathione production.* Milk thistle contains multiple constituents with strong antioxidant activity. Silybin, normally a water-soluble flavonoid, is converted into a lipid-soluble compound by complexing it with phospholipids, such as phosphatidylcholine, to make a phytosome. The phytosome preparation helps with absorption.* Silymarin supports the liver's normal inflammatory response to liver-toxic compounds.* Of the three flavonoids that comprise silymarin, silybin predominates and is the most biologically active of the three.Thorne's logo, text, trademarks, graphics, videos and photo images are the property of Thorne and are used with permission.
