What is HDL Cholesterol? Your Complete Guide
HDL is the 'good' cholesterol — it carries cholesterol away from your arteries and back to the liver for disposal. Higher is better. Think of it as the cleanup crew.
💡Simply Explained
HDL is the "good" cholesterol — it's like a garbage truck that picks up excess cholesterol from your arteries and takes it back to the liver for recycling. More garbage trucks = cleaner streets = healthier arteries.
