Optimal levels for HDL (good) cholesterol are considered 60 mg/dL and higher. Slightly less great but still good levels are between 50 and 59 mg/dL. Levels that cause concern are considered 39 mg/dL or lower for men, and 49 mg/dL or lower for women.
An optimal LDL cholesterol level is below 100 mg/dL, although an LDL level of 100 to 129 mg/dL tends to be safe for most people. High-density lipoprotein cholesterol is a healthy type of cholesterol because it helps remove LDL cholesterol from your system. An HDL cholesterol level of 60 mg/dL and above helps protect against heart disease. In this case, a higher level is healthier.
