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.
For total cholesterol, less than 200 mg/dl is optimal, and the total level should be kept below 240 mg/dl to avoid the risk of heart disease. For LDL, less than 100 mg/dl is optimal, and the total level should be kept below 160 mg/dl. Finally, a healthy HDL level is set above 60 mg/dl, and should be kept above 40 mg/dl for men and above 50 mg/dl for women to prevent excessive accumulation in the blood and along the artery walls.
