HDL ("good") cholesterol acts as your body's cholesterol recycling system. HDL particles scavenge excess cholesterol from artery walls and carry it back to the liver for disposal, a process called reverse cholesterol transport. Higher HDL is generally protective against heart disease. However, very high levels (above 100 mg/dL) may paradoxically increase risk in some people, and medications that artificially raise HDL have not consistently reduced heart attacks, suggesting HDL function matters more than the number alone.
