HDL Cholesterol Levels

HDL stands for High Density Lipoprotein.  It is commonly referred to as good cholesterol since studies indicate that high HDL cholesterol levels in the blood stream can actually reduce the chances of heart disease.

As we explained in the LDL cholesterol levels article, cholesterol is essential and necessary for maintaining strong cell membranes and some hormones such as estrogen and testosterone. However, since cholesterol does not dissolve in blood, it relies on lipo proteins to act as carriers to transport it from liver (where it is generated) to the cells (where it is needed) and then back to the liver (where it is recycled or excreted).

It is believed that the job of HDL, i.e, the High Density Lipoprotein, is to carry the cholesterol from the cells back to the liver where it can be properly disposed. Since high levels of HDL cholesterol could result in moving the plaque forming cholesterol away from the walls of the arteries back to the liver, HDL is generally considered a “good” cholesterol and it is recommended that one should maintain high HDL levels.

Optimal HDL Cholesterol Levels

60 mg/dL and above

HDL cholesterol levels of 60mg/dL and above are considered optimal and can help protect against heart disease. If you are in a high risk category, you should aim to raise your HDL levels to be above this value. 

Moderate HDL Cholesterol Levels

40 mg/dL to 60 mg/dL (for men) and 50 mg/dL to 60 mg/dL (for women)

If your HDL cholesterol is in this range you are not quite at a risk of heart disease, but you could do better. Aim to increase your HDL levels to the optimal range of 60 mg/DL or above to protect your artery walls.

Low HDL Cholesterol Levels

Less than 40 mg/dL (for men) and Less than 50 mg/dL (for women)

Having HDL cholesterol in this range puts you in the risk for heart disease. Make a conscious effort to increase your HDL cholesterol levels to moderate, if not optimal, levels. Evaluate your lifestyle. Smoking, being overweight or not having an active lifestyle can result in HDL cholesterol levels in this range. Focus on lifestyle changes first to improve your HDL levels. If that does not work, speak to your health care provider about alternate options.
