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.
Your HDL should be at least 40 mg/dL, according to guidelines from the National Heart, Lung, and Blood Institute (NHLBI). Since lower levels of good cholesterol appear to cause greater risk of heart disease in women, the American Heart Association (AHA) recommends that women's HDL be at least 50 mg/dl.
