HDL Cholesterol: What Your Good Cholesterol Level Means

HDL (high-density lipoprotein) is known as "good cholesterol" because it carries cholesterol away from arteries and back to the liver for disposal, helping to protect against cardiovascular disease.

What Your Results Mean

Normal

HDL above 60 mg/dL is considered protective against heart disease. Higher HDL levels are associated with lower cardiovascular risk.

High

Very high HDL (above 100 mg/dL) is generally not a concern and is often genetic. However, extremely high levels may in rare cases be associated with certain genetic disorders.

Low

Low HDL (below 40 mg/dL in men, below 50 mg/dL in women) is a major risk factor for heart disease. It means less cholesterol is being removed from arteries.

Frequently Asked Questions

What is a good HDL level? expand_more

Above 60 mg/dL is considered protective. 40–59 mg/dL is acceptable but not optimal. Below 40 mg/dL (men) or 50 mg/dL (women) is low and increases cardiovascular risk.

How can I raise my HDL cholesterol? expand_more

Regular aerobic exercise is the most effective way to raise HDL. Quitting smoking, reducing refined carbohydrates, consuming healthy fats (olive oil, avocado, nuts), and moderate alcohol consumption also help.

Is higher HDL always better? expand_more

Generally yes, up to a point. Very high HDL (above 100 mg/dL) does not provide additional benefit and some research suggests extremely high levels may paradoxically increase risk in certain populations.

What causes low HDL? expand_more

Smoking, physical inactivity, obesity, a diet high in refined carbohydrates, type 2 diabetes, and certain medications are the most common causes of low HDL.
