HDL Cholesterol

HDL is the cholesterol particle that carries excess cholesterol back to the liver for clearance — often called the protective lipid because a low reading correlates with cardiovascular risk.

Reference range

Male: 40–999 mg/dL (optimal ≥ 45 mg/dL)
Female: 50–999 mg/dL (optimal ≥ 55 mg/dL)

Watch points

Critical: at or below 30 mg/dL
High: at or below 40 mg/dL

Same thresholds apply to men and women in this table.

Why hard-training athletes watch it

Steady-state cardio and consistent training raise HDL over months, while a recomposition phase heavy on saturated fat and light on activity can quietly lower it — a lifter who only tracks LDL is missing half the lipid picture.

When to retest

A fasting lipid panel every 3–6 months during an active training block is enough to see a real trend; a single post-holiday reading is noise.

Talk to your clinician

Add steady cardio and discuss your lipid profile with your clinician. A reading below the reference band is a common, routine finding — bring your full lipid panel, not just HDL alone, to your clinician for context.
