What is a normal LDL level?
LDL (low-density lipoprotein) carries cholesterol to your arteries. Elevated LDL is a primary driver of atherosclerosis and cardiovascular disease. The AHA/ACC recommends keeping LDL below 100 mg/dL, but longevity-focused physicians target below 80 mg/dL.
| Range | Values |
|---|---|
| Standard Reference | 0–100 mg/dL |
| Optimal | 0–100 mg/dL |
| Longevity Optimal | < 80 mg/dL |
| High Risk | > 160 mg/dL |
What causes abnormal LDL levels?
High LDL cholesterol is commonly caused by a diet high in saturated and trans fats, genetic conditions like familial hypercholesterolemia, obesity, lack of physical activity, smoking, and certain medications. Age and sex also play a role — LDL tends to rise with age, and women often see increases after menopause.
When should you see a doctor?
See your doctor if your LDL is above 160 mg/dL, if you have a family history of heart disease or high cholesterol, or if you have other cardiovascular risk factors like high blood pressure, diabetes, or smoking. If your LDL is between 100-160 mg/dL, discuss lifestyle changes and whether medication is appropriate.
