Siliphos combines a flavonoid from milk thistle (silybin) with phospholipids to form a well-absorbed complex. It offers liver-protective benefits and helps maintain normal levels of glutathione. Silymarin has been shown to help maintain the liver's normal inflammatory response to liver-toxic compounds.
Milk thistle contains multiple constituents with strong antioxidant activity 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, the milk thistle constituent silybin – the most active flavonoid in milk thistle – has been utilized to prevent liver cell damage from carbon tetrachloride, ethanol, acetaminophen, mushroom toxins, and benzopyrene from automobile exhaust. Thorne's Siliphos provides the benefits of silybin and phosphatidylcholine in one well-absorbed compound. These ingredients likely provide the synergistic benefit of sparing liver cells from degradation. Studies indicate this silybin-phosphatidylcholine complex provides superior absorption compared to conventional milk thistle products.
