Primary

Protects hepatocyte-membrane stability

Seed extract delivers silibinin and related lignans to the hepatocyte membrane and lessens toxin and oxidative interference with membrane structure. People with a dull right-upper-quadrant fullness after drinking at gatherings and oily eating-out more often see change in abdominal comfort and related enzyme markers after several continuous weeks.

Primary

Helps the hepatic glutathione network

Milk-thistle seed constituents can support regeneration of reduced glutathione in the liver so electrophilic metabolites are more readily conjugated and cleared. People who have long felt a bitter mouth and morning fatigue and who attend to hepatic oxidative load more often see a difference in mental freshness after several continuous weeks.
