Siliphos (Silybin Phytosome)

A milk thistle product. 


Milk thistle has been in common use for many years as a natural treatment for liver diseases. The active constituents of milk thistle have been well-studied and shown to possess antioxidant and NRF2 activator properties. Pre-clinical and clinical studies support their benefit in liver disease, especially non-alcoholic fatty liver disease.

Product Description

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.*


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.*


Drug Interactions with Silybin

While the clinical significance has not yet been established, Silybin has been shown to inhibit P-gp, a transporter that affects blood levels and central nervous system levels of certain drugs. As a result of this inhibition, it may be possible that Silybin can decrease blood levels but at the same time increase central nervous levels of fentanyl, morphine, methadone and possibly oxycodone. This could result in either increased or decreased therapeutic effect and/or side effects. When taking Silybin while also taking these medications, caution should be emphasized by monitoring for changes in responsiveness to the medications and it may be necessary to reduce the dose of these medications to avoid side effects.
