Thorne Research Siliphos®

Normal Glutathione Levels and Liver Support

Antioxidant - 90 Capsules

Thorne Research Siliphos® has liver-protective benefits from milk thistle extract and phosphatidylcholine and supports the liver and normal glutathione levels.

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.

Highly Bioavailable Silybin-Phosphatidylcholine Complex

  • Provides potent liver support
  • Helps maintain normal glutathione levels
  • Phytosome preparation provides higher liver concentrations of silybin
  • Dual liver-protective benefits from milk thistle extract and phosphatidylcholine

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 potent. 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 potent antioxidant activity, while phosphatidylcholine helps repair and replace cell membranes. These constituents likely offer the synergistic benefit of sparing liver cells from destruction.
