What is the normal HDL level range considered healthy?

Less than 40 mg/dL
50 mg/dL or higher
40-50 mg/dL
60 mg/dL or higher

The correct answer is: 50 mg/dL or higher

A normal HDL (high-density lipoprotein) level is considered healthy when it is 50 mg/dL or higher. HDL is often referred to as "good" cholesterol because it helps transport cholesterol to the liver for excretion, thus reducing the risk of cardiovascular diseases. Higher levels of HDL cholesterol are generally associated with lower risks for heart disease and stroke. In healthy individuals, HDL levels above 50 mg/dL indicate an adequate protective effect against heart conditions. Levels below 40 mg/dL are considered a risk factor for cardiovascular problems, particularly in men. Therefore, understanding the significance of maintaining HDL within the recommended range is crucial for promoting heart health and preventing disease. The other specified ranges do not denote a healthy HDL level. For instance, less than 40 mg/dL signifies a potential risk, while the range of 40-50 mg/dL is still below the optimal threshold. Additionally, while 60 mg/dL or higher is indeed beneficial, it is not the minimum threshold for what is considered healthy; the critical benchmark starts at 50 mg/dL.
