Were you looking for information about HDL? Good cholestrol is a common misspelling of good cholesterol.
Also known as "good" cholesterol, HDL (high density lipoprotein) is a waxy substance that is used to transport cholesterol in the blood. HDL is considered "good" cholesterol because it removes excess "bad" cholesterol (LDL). Therefore, it is good to have high levels of HDL in your blood and low levels of LDL. An HDL level of 60 mg/dL and above is considered good (the higher the better), while numbers below this level put you at risk for developing heart disease.
