What is the normal LDL cholesterol range?

A healthy LDL cholesterol range is anything from below 100 to 129 mg per deciliter of blood, or mg/dL. 7 The target level should be 50-70 mg/dL to prevent plaque formation in your arteries. 7 The risk of plaque buildup is increased by diabetes, high blood pressure, smoking, or a pre-existing atherosclerosis.
