VLDL cholesterol: Is it harmful?

Very-low-density lipoprotein (VLDL) cholesterol is a type of lipoprotein. Although you may hear about VLDL, your VLDL level usually isn't reported to you as a part of a routine cholesterol test.

There are several types of cholesterol, each made up of lipoproteins and fats. Each type of lipoprotein contains a mixture of cholesterol, protein and a type of fat (triglyceride), but in varying amounts.

Of the lipoprotein types, VLDL contains the highest amount of triglyceride. Because it contains a high level of triglyceride, having a high VLDL level means you may have an increased risk of coronary artery disease, which can lead to a heart attack or stroke.

There's no simple, direct way to measure VLDL cholesterol, which is why it's normally not mentioned during a routine cholesterol screening. VLDL cholesterol is usually estimated as a percentage of your triglyceride value. A normal VLDL cholesterol level is between 5 and 40 milligrams per deciliter.
