HDL

High-Density Lipoprotein (HDL) is one of the lipoprotein types responsible for transporting cholesterol and triglycerides within the bloodstream. HDL is known for being beneficial as it helps remove cholesterol from arteries and transport it back to the liver, where it can be processed and eliminated. This action of HDL is often referred to as "reverse cholesterol transport" and is why HDL is commonly labeled as "good cholesterol."

In a discussion with Dr. Peter Attia on the Huberman Lab, the properties of HDL and its role in cardiovascular health were explained. HDL falls under the category of lipoproteins that are wrapped in apolipoprotein A, characterized by a higher density of protein relative to lipid content. This composition enables HDL to function effectively in its role of cholesterol management within the body 1 2.
