Best Supplements for High Cholesterol: What Lowers LDL
Plant sterols and psyllium reliably lower LDL; red yeast rice works but acts like a statin. Fish oil lowers triglycerides, not LDL. See doses and safety.

The best supplements for high cholesterol are plant sterols or stanols and psyllium fiber, which each lower LDL cholesterol by a modest, reliable amount. Red yeast rice lowers LDL because it can contain the same compound as the statin lovastatin, with the same risks. Fish oil lowers triglycerides but not LDL. Supplements don't match statins for preventing heart attacks.
