What is Non-HDL Cholesterol?

Your total cholesterol minus your good HDL cholesterol, so it captures all the cholesterol carried by particles that can clog arteries.

Non-HDL cholesterol rolls together every kind of artery-clogging cholesterol particle into a single number, giving a fuller view of risk than LDL alone. A higher non-HDL number can be associated with more of these particles in the blood and a greater long-term risk of heart and blood-vessel problems. An optimal level for most people is often described as under 130 mg/dL.
