Milk thistle uses a seed extract; silymarin is the flavonolignan mixture in it, used for hepatocyte-membrane stability and glutathione-related antioxidant protection.

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.

Fatigue

People who cannot get going by day and feel foggy in the afternoon more often notice stamina for tasks and mental freshness after several continuous weeks.

Non-alcoholic fatty liver disease

Seed extract delivers silibinin and related lignans to the hepatocyte membrane and lessens toxin and oxidative interference with membrane structure. People whose imaging or enzyme markers suggest fatty liver and who feel fullness under the right ribs more often notice abdominal feel and labs after several continuous weeks.
