HDL cholesterol, often called the "good" cholesterol, plays a crucial role in maintaining heart health. But what exactly makes it so important? HDL helps remove other forms of cholesterol from your bloodstream, reducing the risk of heart disease. Unlike its counterpart, LDL (low-density lipoprotein), which can clog arteries, HDL works to keep them clear. Understanding the benefits of HDL can empower you to make healthier lifestyle choices. From diet tips to exercise routines, there are many ways to boost your HDL levels naturally. Ready to learn some surprising facts about HDL cholesterol? Let's dive in!
What is HDL Cholesterol?
High-Density Lipoprotein (HDL) cholesterol is often called the "good" cholesterol. It helps remove other forms of cholesterol from your bloodstream. Higher levels of HDL are associated with a lower risk of heart disease.
- 01
HDL stands for High-Density Lipoprotein. It carries cholesterol from other parts of your body back to your liver, which removes it from your body.
- 02
HDL is known as "good" cholesterol. Unlike Low-Density Lipoprotein (LDL), which can clog arteries, HDL helps clear cholesterol from your blood vessels.
- 03
HDL levels are measured in milligrams per deciliter (mg/dL). Doctors use this measurement to assess your risk for heart disease.
- 04
Higher HDL levels are better. An HDL level of 60 mg/dL or higher is considered protective against heart disease.
How HDL Cholesterol Works
Understanding how HDL functions can help you appreciate its role in maintaining heart health. Here are some key points about its mechanism.
- 05
HDL removes excess cholesterol. It transports cholesterol to the liver, where it can be processed and excreted.

HDL has anti-inflammatory properties. It can reduce inflammation in your blood vessels, lowering the risk of heart disease.
- 07
HDL helps repair damaged blood vessels. It promotes the healing of the endothelium, the inner lining of blood vessels.

HDL can act as an antioxidant. It prevents the oxidation of LDL cholesterol, which is a key step in the formation of artery-clogging plaques.
