High ldl cholesterol

A medical finding, review with a doctor

A high LDL raises cardiovascular risk and is a medical decision; omega-3, bergamot, and berberine can support a healthier profile, but they sit alongside, not instead of, your doctor's plan.

LDL carries cholesterol into artery walls, so a high level over time raises heart-disease risk, weighed against your other risk factors. Diet and exercise move it, and some supplements help modestly: bergamot and berberine for LDL, omega-3 for triglycerides. Red yeast rice is effectively a low-dose statin and must be used only under medical supervision.
