A well-researched, standardized botanical extract, milk thistle contains potent antioxidants that can protect liver cells from free radical damage, strengthen liver cell membranes, and help maintain the liver's built-in antioxidant system – glutathione and superoxide dismutase (SOD).* In numerous studies, its active ingredient, silymarin, has been utilized to prevent liver cell damage by carbon tetrachloride, ethanol, acetaminophen, mushroom toxins, and benzopyrene from automobile exhaust.* Silymarin has also been shown to help maintain the body's normal inflammatory response in the liver.*

Siliphos provides the benefits of silymarin (flavonoid complex from milk thistle) and phosphatidylcholine in one compound.* Siliphos is a phytosome, a water-soluble flavonoid (in this case, silybin) made lipid-friendly by the addition of phosphatidylcholine. This allows for better incorporation of this liver-protective flavonoid into liver cell membranes.* Of the three flavonoids comprising silymarin, silybin predominates and is the most biologically active. Studies indicate the silybin-phosphatidylcholine complex in Siliphos provides superior bioavailability compared to conventional milk thistle products.*

Phosphatidylcholine is not merely a passive "carrier" for the active flavonoid silybin, but is itself an active ingredient with documented efficacy for promoting liver health.* Silybin protects the liver because of its significant antioxidant activity, while phosphatidylcholine helps repair and replace cell membranes.* These constituents likely offer the synergistic benefit of sparing liver cells from destruction.*
