Protects hepatocyte-membrane stability

Lignans such as silybin can embed in hepatocyte membranes and reduce interference from toxins and bile acids, so markers of hepatocyte integrity are watched. For people with right-upper-quadrant fullness after drinking at meals, or enzymes that run high, changes in abdominal feel and those markers are more often noticeable after several weeks of continued use.

Helps the liver handle oxidative load

Silymarin can support the hepatic glutathione network and trap electrophilic metabolites, so oxidative load more often falls with continued use. For people with oily takeout, a heavy drug-metabolism burden, and a bitter mouth plus fatigue, differences in energy and digestive comfort are more often noticeable after several weeks of continued use.
