Cholesterol Levels by Age Chart: Normal Ranges (mg/dL)

Yes, cholesterol serves as the biochemical precursor that your body uses to make testosterone and every other steroid hormone. As documented in research archived by the National Institutes of Health (NIH), synthesis begins inside mitochondria when cholesterol converts into pregnenolone. That rate-limiting step is regulated by luteinizing hormone (LH) and catalyzed by the enzyme cytochrome P450 family 11 subfamily A member 1 (CYP11A1), before the testes complete production through several additional enzymatic steps. Your body requires adequate cholesterol to maintain this pathway, but clinically low testosterone caused by low cholesterol alone is unusual in people with typical or low-normal lipid numbers. This biological requirement does not provide a reason to avoid lowering high cholesterol. The relationship also runs in the other direction and is documented more thoroughly. A five-year prospective study in the European Journal of Preventive Cardiology found that men with lower total testosterone had higher triglycerides and lower high-density lipoprotein (HDL) cholesterol. Participants with lower testosterone also developed dyslipidemia at higher rates over the five years. This pattern indicates a statistical association. It does not prove that low testosterone directly causes lipid changes, because aging, obesity, and metabolic syndrome often occur alongside lower hormone levels. If you want to evaluate your hormone numbers alongside your lipid panel, check our guide to testosterone levels by age for typical ranges and testing guidance.

The 2026 ACC/AHA dyslipidemia guideline replaced the 2018 cholesterol guideline. It restored numeric LDL goals by risk (under 100, 70, or 55 mg/dL), recommended once-in-a-lifetime lipoprotein(a) screening for all adults, and formally recommended at least 5% weight loss for people who are overweight. See our full guide to the 2026 cholesterol guidelines for details.

A normal total cholesterol level is below 200 mg/dL for most adults of any age, per the CDC. LDL should stay below 100 mg/dL and triglycerides below 150 mg/dL. These targets stay similar across adult age groups. Children should stay below 170 mg/dL total.

Normal means your level falls within the common acceptable range, while optimal means the level tied to the lowest heart risk. For example, an LDL of 120 mg/dL is normal but not optimal. The AHA notes lower LDL is generally better. High-risk people often aim for LDL below 70 mg/dL.

Healthy ranges are LDL below 100 mg/dL, HDL at or above 60 mg/dL, and triglycerides below 150 mg/dL. These come from the NCEP ATP III report. HDL below 40 mg/dL is considered too low. Triglycerides at or above 500 mg/dL are very high and need urgent care.

Children and teens aged 2–19 should have total cholesterol below 170 mg/dL and LDL below 110 mg/dL, per the NHLBI. Levels of 170–199 mg/dL total are borderline. A total of 200 mg/dL or higher is high. The CDC advises screening once between ages 9 and 11.

Most adults should check cholesterol every 4 to 6 years starting at age 20, per the AHA. People with diabetes, high blood pressure, or a family history may need checks more often. A full lipid panel is part of a comprehensive workup. You can review it alongside a comprehensive metabolic panel.

For most people, no — dietary cholesterol (the cholesterol you eat, like the ~185 mg in one egg yolk) has a much smaller effect on blood cholesterol than saturated fat does for the average person. This is why the US Dietary Guidelines dropped their long-standing 300 mg/day dietary cholesterol limit back in 2015: the body makes most of its own blood cholesterol in the liver and adjusts production down somewhat when dietary intake rises, so eggs in moderation (current AHA guidance: up to one egg a day is fine within an otherwise healthy diet) aren't the driver of high LDL for most people. The exception is a subset of "hyper-responders" whose LDL does rise meaningfully with dietary cholesterol intake — if your LDL is already elevated or you have known heart disease, ask your clinician whether you're likely to be in that group before assuming eggs are automatically fine. Saturated fat (butter, fatty meat, full-fat dairy) remains the bigger lever for most people's LDL than any single cholesterol-containing food.

Non-HDL cholesterol is your total cholesterol minus HDL — a single number that captures every artery-clogging ("atherogenic") particle in your blood, not just LDL. That includes LDL, VLDL, IDL, and lipoprotein(a), which is why many labs and the 2026 ACC/AHA dyslipidemia guideline treat it as at least as good a risk predictor as LDL alone, and arguably better when triglycerides are elevated, since high triglycerides make the standard LDL calculation less reliable (see the LDL calculated vs. direct question below). The target follows a simple rule: non-HDL goal equals your LDL goal plus 30 mg/dL. So if your LDL target is under 100 mg/dL, your non-HDL target is under 130 mg/dL; a target of 70 mg/dL becomes 100 mg/dL non-HDL, and 55 mg/dL becomes 85 mg/dL. Unlike LDL, non-HDL cholesterol doesn't require a fasting blood draw to measure accurately, which is part of why it's gained favor for routine screening.

Most lab reports list LDL cholesterol as "calculated" rather than directly measured. Labs use the Friedewald equation — LDL = Total cholesterol − HDL − (Triglycerides ÷ 5) — to estimate LDL from your other three lipid values, since directly measuring LDL used to be expensive and slow. This calculation works well for most people, but it becomes unreliable once triglycerides climb above 400 mg/dL, or if the blood draw wasn't fasting, because the formula assumes a fixed ratio between triglycerides and VLDL cholesterol that breaks down at high triglyceride levels — in that range, calculated LDL tends to underestimate the true value. "LDL direct" is a separate lab method that measures LDL particles directly rather than deriving them from the other three numbers; it costs more and isn't run by default, but it's the more accurate option when triglycerides are high, the sample is non-fasting, or in someone with diabetes or metabolic syndrome, where elevated triglycerides are common. If your report says "LDL Calc" or "LDL Cholesterol Calc," that's the Friedewald estimate; "LDL Direct" means it was actually measured.

Not exactly, though the terms overlap heavily. Hyperlipidemia is the clinical umbrella term for any elevated blood lipid — cholesterol, triglycerides, or both — and it's the diagnosis code your doctor is more likely to actually use. "High cholesterol" in everyday language usually refers to one specific piece of that picture: elevated LDL or total cholesterol. Since hyperlipidemia can also be driven by high triglycerides alone with normal cholesterol, someone can have hyperlipidemia without technically having "high cholesterol," which is why the lipid panel breaks these values out separately rather than reporting a single number.

Yes — several non-statin, FDA-approved options exist, and a doctor may consider them alongside or instead of a statin depending on the situation, not as a reason to avoid statins altogether. Ezetimibe lowers LDL by blocking cholesterol absorption in the gut and is often added to a statin or used alone if statins aren't tolerated. PCSK9 inhibitors — injectable antibody drugs including evolocumab and alirocumab — produce larger LDL reductions and are FDA-approved for people with familial hypercholesterolemia or existing cardiovascular disease who need additional lowering beyond a statin. Bempedoic acid is a once-daily oral non-statin approved for similar situations, including for people who can't tolerate statin side effects. As the section above on improving your numbers makes clear, statins remain a first-line, well-studied option for many people — these alternatives exist for when a statin isn't enough, isn't tolerated, or isn't the right fit, and choosing between them is a conversation to have with your doctor based on your full risk profile.

Your cholesterol ratio — total cholesterol divided by HDL — is a separate metric from any single number above, and some clinicians use it as a quick cross-check. According to Mayo Clinic, most people should aim for a ratio below 5:1, with under 3.5:1 considered especially favorable; since HDL targets differ by sex (≥40 mg/dL for men, ≥50 mg/dL for women), the ratio a man and a woman need to hit the same target number can differ. To calculate it, divide your total cholesterol by your HDL from a recent lipid panel — a total of 200 with an HDL of 50 gives a ratio of 4. Mayo Clinic notes this ratio has largely been supplanted by non-HDL cholesterol and direct LDL goals (see above) as the primary treatment target in current guidelines — it's still a useful quick read, but your clinician is more likely to focus on your LDL and non-HDL numbers when deciding on treatment. A related value, VLDL cholesterol, isn't usually measured directly either — it's typically estimated as triglycerides ÷ 5 (the same VLDL estimate used inside the Friedewald LDL calculation above) rather than reported or targeted as its own number.

Yes — a substantial, expected rise. During a normal pregnancy, total cholesterol typically climbs from around 180 mg/dL at the end of the first trimester to roughly 230 mg/dL by the third trimester, according to a review in the NIH's Endotext reference on lipid metabolism in pregnancy — driven by rising estrogen, which increases the liver's production of lipoproteins to support placental hormone production and fetal development. LDL rises roughly 30-40% and HDL about 25% over the same period, while triglycerides can climb two- to three-fold — a pattern sometimes called physiological hypercholesterolemia, distinct from the high-cholesterol ranges elsewhere on this page, which reflect a non-pregnant baseline. These changes reverse on their own after delivery and breastfeeding, as lipid levels return toward pre-pregnancy levels within weeks to months. A lipid panel drawn during pregnancy isn't meant to be compared against the general-population ranges above — ask your OB about pregnancy-specific interpretation rather than assuming a pregnancy result that looks "high" by the standard chart is a problem.
