What are the best cholesterol levels for an adult human?

Many factors affect our body—one of them has to do with our cholesterol levels, especially in terms of our heart. The following, from the American Heart Association, lists what is currently thought to be the best cholesterol levels for an adult:

Total Cholesterol


Less than 200 mg/dL

Desirable level that puts you at lower risk for coronary heart disease.


A cholesterol level of 200 mg/dL or higher raises your risk.

200 to 239 mg/dL

Borderline high

240 mg/dL and above

High blood cholesterol. A person with this level has more than twice the risk of coronary heart disease as someone whose cholesterol is below 200 mg/dL.
