High-density lipoprotein (HDL) is often referred to as the "good" cholesterol. It plays a crucial role in transporting cholesterol from the body's tissues to the liver, where it can be removed from the body. Higher levels of HDL cholesterol are associated with a reduced risk of cardiovascular diseases, while lower levels are linked to an increased risk. The American Heart Association, NIH, and NCEP provide the following guidelines for fasting HDL levels and risk for heart disease:
- Less than 40/50 mg/dL for men/women: Low HDL cholesterol, heightened risk considered correlated for heart disease.
- 40–59 mg/dL: Medium HDL level.
- Above 59 mg/dL: High HDL level, optimal condition considered correlated against heart disease
The Mayo Clinic suggests that HDL cholesterol levels greater than 60 mg/dL are high and offer protection against heart disease, while levels less than 40 mg/dL are low
. Similarly, WebMD states that HDL cholesterol levels greater than 60 mg/dL are high and levels less than 40 mg/dL are low
. The Cleveland Clinic also recommends that HDL should ideally be above 60, as it offers protection against heart disease
. Harvard Health mentions that guidelines recommend an HDL level of 40 mg/dL to 60 mg/dL for adult men, and a level below 40 mg/dL could mean that there is not enough HDL to do its job properly
. In summary, a good HDL level is generally considered to be above 60 mg/dL, as it is associated with a reduced risk of cardiovascular diseases.
