HDL Cholesterol
High-density lipoprotein – the 'good' cholesterol
Also known as
HDL HDL-C good cholesterol high-density lipoprotein
Definition
HDL cholesterol facilitates reverse cholesterol transport by shuttling excess cholesterol from arterial walls back to the liver. High HDL levels are considered cardioprotective, although HDL function (cholesterol efflux capacity) matters more than the measured value alone. Regular physical activity and smoking cessation sustainably raise HDL levels.
