Understanding Low LDL Cholesterol Levels

LDL (Low-Density Lipoprotein) cholesterol, while often called “bad” cholesterol, is still necessary for normal body function. Low LDL levels (below 50 mg/dL) may indicate certain health conditions or be a result of intensive cholesterol-lowering therapy.

What is Considered Low?

An LDL cholesterol level below 50 mg/dL is considered low. While lower LDL is generally beneficial, extremely low levels may be concerning:

  • Below 50 mg/dL: Low
  • Below 40 mg/dL: Very low
  • Below 25 mg/dL: Extremely low
