Viscous soluble psyllium husk forms a non-absorbable gel in the intestinal lumen that sequesters bile acids, forcing the liver to deplete intrahepatic cholesterol to synthesize new bile; plant phytosterols competitively displace dietary and biliary cholesterol from mixed micelles at the NPC1L1 transporter.
