Product education

Siliphos®: A Highly Absorbable Silybin Phytosome for Liver Support*

Thorne’s Siliphos® provides an advanced form of milk thistle extract for exceptional liver health support. The key active component in milk thistle is silybin phytosome, a powerful antioxidant that protects liver cells. However, the body normally struggles to absorb standard silybin. Siliphos® solves this problem using phytosome technology, which binds the silybin to phospholipids.*

How It Works: The Phytosome Power for Liver Wellness

Siliphos® enhances the body’s natural antioxidant defenses. It also supports the liver’s crucial role as the body’s primary filter.*

Superior Absorption for Enhanced Protection
The Siliphos® phytosome technology creates a complex that is more easily transported across intestinal cell membranes. In fact, clinical studies show Siliphos® is absorbed up to 10 times better than standard milk thistle. This superior bioavailability ensures that a clinically effective amount of silybin reaches the liver to perform its key functions.*

Supporting Detoxification and Glutathione
Once absorbed, silybin works by directly scavenging for damaging free radicals. In addition, it supports the body’s own antioxidant systems by helping to maintain and increase glutathione levels. By bolstering these defenses, Siliphos® helps maintain the health of liver cell membranes. This also supports the liver’s Phase II detoxification pathways, which are essential for neutralizing and eliminating toxins.*

  • Provides powerful antioxidant support for liver cells*
  • Features silybin phytosome for up to 10x greater absorption than standard extracts*
  • Supports the body’s natural production of glutathione*
  • Aids the liver’s natural detoxification processes
  • NSF Certified for Sport®, trusted for purity and safety
