Normal Cholesterol Levels by Age and What Your Results Mean

For adults 20 and older, normal cholesterol means a total cholesterol below 200 mg/dL, LDL cholesterol below 100 mg/dL, HDL cholesterol of 60 mg/dL or higher, and triglycerides below 150 mg/dL. For children and teens 19 and younger, healthy levels are lower, with total cholesterol below 170 mg/dL and LDL below 110 mg/dL. Cholesterol tends to rise with age, especially in women after menopause, but a higher number is never a safe new normal. An LDL of 160 mg/dL or higher is high for adults, and an LDL of 190 mg/dL or higher often needs treatment right away.

What Is Cholesterol and Why Does It Matter?

Cholesterol is a waxy, fat like substance found in every cell of your body. Your liver makes most of the cholesterol you need, and the rest comes from foods such as meat, eggs, butter, and cheese. Your body uses cholesterol to build cell walls, make hormones such as estrogen and testosterone, produce vitamin D, and form bile that helps digest fat.

Cholesterol cannot travel through the blood on its own, so it rides inside particles called lipoproteins. When too much cholesterol builds up in the blood, it sticks to the inner walls of your arteries and forms plaque. Over time, plaque narrows and hardens the arteries. A piece of plaque can break open and form a clot, which can cause a heart attack or stroke.

High cholesterol causes no symptoms, so most people do not know they have it until a blood test shows it. About 86 million adults in the United States have a total cholesterol of 200 mg/dL or higher. Heart disease is the leading cause of death for both men and women in the country. A simple blood test called a lipid panel is the only way to know your numbers.

What Each Cholesterol Number Means?

A lipid panel measures several numbers, and each one tells your doctor something different about your heart health. The sections below explain LDL, HDL, triglycerides, and total and non HDL cholesterol.

1. LDL Cholesterol (Bad Cholesterol)

LDL stands for low density lipoprotein, and many people call it bad cholesterol. LDL carries cholesterol to your cells, but extra LDL settles inside artery walls and forms plaque. This process is called atherosclerosis. The more LDL in your blood and the longer it stays high, the greater your risk of a heart attack, stroke, or blocked arteries in the legs.

For most adults, an LDL below 100 mg/dL is optimal. A level of 100 to 129 mg/dL is near optimal, 130 to 159 mg/dL is borderline high, 160 to 189 mg/dL is high, and 190 mg/dL or higher is very high. People with heart disease or diabetes often aim for an LDL below 70 mg/dL, and some high risk patients aim even lower.

2. HDL Cholesterol (Good Cholesterol)

HDL stands for high density lipoprotein, often called good cholesterol. HDL works like a cleanup crew. It picks up extra cholesterol from your arteries and carries it back to the liver, which removes it from the body. Higher HDL levels are linked to a lower risk of heart disease, which is why this is the one number you want to be high.

An HDL of 60 mg/dL or higher helps protect your heart. An HDL below 40 mg/dL in men or below 50 mg/dL in women raises the risk of heart disease. Extra weight, smoking, little exercise, and type 2 diabetes all lower HDL. Regular activity, quitting smoking, and healthy fats from olive oil, nuts, and fish can help raise it over time.

3. Triglycerides

Triglycerides are a type of fat in your blood that stores extra calories for energy. When you eat more calories than your body burns, especially from sugar, white bread, and alcohol, your body turns the extra into triglycerides. High levels often come with extra weight, high blood sugar, and a low HDL, a pattern that raises heart risk over time.

A triglyceride level below 150 mg/dL is normal. A level of 150 to 199 mg/dL is borderline high, 200 to 499 mg/dL is high, and 500 mg/dL or higher is very high. Very high triglycerides raise the risk of pancreatitis, a painful swelling of the pancreas that needs prompt care. A diet with less sugar, refined carbs, and alcohol often lowers triglycerides within a few weeks.

4. Total and Non HDL Cholesterol

Total cholesterol adds together your LDL, your HDL, and part of your triglycerides. A total below 200 mg/dL is desirable for adults, 200 to 239 mg/dL is borderline high, and 240 mg/dL or higher is high. Total cholesterol alone does not tell the full story. A person with a high HDL can have a higher total and still have healthy arteries.

Non HDL cholesterol is your total cholesterol minus your HDL. It includes every type of cholesterol that can clog arteries, not just LDL. Many doctors now consider it a better predictor of heart risk than LDL alone, especially for people with high triglycerides or diabetes. A non HDL level below 130 mg/dL is desirable for most adults, and lower is better for people at high risk.

Normal Cholesterol Levels by Age

Healthy cholesterol targets are the same for all adults, but average levels change as you get older. Children and teens have their own lower ranges. The sections below explain what normal looks like at each stage of life.

1. Cholesterol Levels for Children and Teens (19 and Younger)

Children and teens have lower healthy ranges than adults. Acceptable levels are a total cholesterol below 170 mg/dL, LDL below 110 mg/dL, HDL above 45 mg/dL, and non HDL cholesterol below 120 mg/dL. Triglycerides should stay below 75 mg/dL for children up to age 9, and below 90 mg/dL for ages 10 to 19. A total of 200 mg/dL or higher is high for kids.

The National Heart, Lung, and Blood Institute recommends a cholesterol test for every child between ages 9 and 11, and again between 17 and 21. Children with a family history of early heart disease or high cholesterol can be tested as early as age 2. Our blog on the Well Child Visit Schedule explains which health checks happen at each childhood checkup.

2. Cholesterol Levels for Adults Ages 20 to 39

Young adults usually have the lowest cholesterol of any adult group. Normal levels are a total below 200 mg/dL, LDL below 100 mg/dL, HDL of 60 mg/dL or higher, and triglycerides below 150 mg/dL. Many people in their 20s and 30s skip cholesterol tests because they feel healthy, but plaque can start forming in the arteries in early adulthood, years before any symptoms appear.

High cholesterol at a young age often runs in families. Familial hypercholesterolemia, an inherited condition that affects about 1 in 250 people, causes an LDL of 190 mg/dL or higher from childhood. Our guide on What Causes High Cholesterol explains how genes, diet, weight, and daily habits each push cholesterol higher, even in young and active adults who feel healthy.

3. Cholesterol Levels for Adults Ages 40 to 59

Cholesterol tends to climb through middle age as metabolism slows and weight increases. The healthy targets stay the same, with total cholesterol below 200 mg/dL and LDL below 100 mg/dL for most adults. Type 2 diabetes, high blood pressure, and less physical activity become more common in this age group, and each one makes high cholesterol more harmful to your heart and blood vessels.

An underactive thyroid is another common cause of rising LDL in middle age, especially in women. Low thyroid hormone slows the way your liver clears cholesterol from the blood. Our post on Thyroid Function Test explains how doctors check thyroid levels when cholesterol rises without a clear reason, and what each result means.

4. Cholesterol Levels for Adults 60 and Older

Cholesterol often peaks between ages 60 and 70, then levels off or falls slightly. Even though averages rise, a healthy target is still a total below 200 mg/dL and an LDL below 100 mg/dL. Older adults with heart disease or diabetes often aim for an LDL below 70 mg/dL to lower the risk of another heart attack or stroke.

Heart disease risk rises with age, so cholesterol control matters even more after 60. Statins such as atorvastatin and rosuvastatin remain safe and effective for most older adults, and guidelines support starting them up to age 75 for people at high risk. Your doctor weighs your age, your other health conditions, and your current medicines before setting a personal cholesterol goal that fits your overall health.

Cholesterol Levels Chart for Adults and Children

This chart compares healthy, borderline, and high cholesterol levels for children and adults, based on guidelines from the National Heart, Lung, and Blood Institute and the American Heart Association. All numbers are in mg/dL.

Normal Cholesterol Levels for Men vs Women

The healthy targets for total cholesterol, LDL, and triglycerides are the same for men and women. The main difference is HDL. Women need an HDL of at least 50 mg/dL, while men need at least 40 mg/dL. Women usually have HDL levels about 10 mg/dL higher than men, partly because estrogen helps raise good cholesterol during the childbearing years.

Men tend to see their LDL rise earlier, often in their 30s and 40s. Men also face heart attacks about 7 to 10 years earlier than women on average. Extra belly fat, low testosterone, smoking, and heavy drinking push cholesterol higher in men. For this reason, many doctors start closer cholesterol checks in men by age 45 or sooner if risk factors exist.

Women often see a sharp rise in cholesterol after menopause, when estrogen levels fall. LDL and triglycerides climb, and HDL can drop, so many women over 55 have higher total cholesterol than men their age. Pregnancy also raises cholesterol for a short time, which is normal. Our guide on Hormone Replacement Therapy for Women explains how estrogen affects heart health after menopause.

What Your Cholesterol Results Mean?

Your doctor reads all your numbers together, not just one. A high LDL with a low HDL and high triglycerides carries more risk than a high LDL alone. This pattern often appears in people with prediabetes or extra belly fat. Some reports also show a total cholesterol to HDL ratio, where a ratio below 5 is good and below 3.5 is ideal.

Cholesterol is only one part of your heart risk. Doctors use a risk calculator that includes your age, sex, blood pressure, blood sugar, and smoking status to estimate your 10 year risk of heart attack or stroke. High cholesterol often appears with high blood pressure and high blood sugar, and our guides on Normal Blood Pressure by Age and Normal Blood Sugar Levels by Age explain those numbers too.

How to Lower Your Cholesterol Naturally?

Daily habits can lower your cholesterol in a meaningful way, often by 10 to 20 percent. The sections below explain the food choices and lifestyle changes that make the biggest difference.

1. Foods That Lower Cholesterol

Soluble fiber binds cholesterol in the gut and helps remove it from the body. Good sources include oats, beans, lentils, apples, pears, barley, and chia seeds. About 5 to 10 grams of soluble fiber each day can lower LDL by about 5 percent. Nuts, avocados, olive oil, and fatty fish such as salmon also support healthy cholesterol levels and a healthier heart.

The American Heart Association advises keeping saturated fat below 6 percent of daily calories, which is about 13 grams on a 2,000 calorie diet. Cut back on fatty red meat, butter, cheese, fried foods, and baked goods. Avoid trans fats completely, since they raise LDL and lower HDL at the same time. Plant sterols in fortified foods can lower LDL by up to 10 percent.

2. Exercise, Weight Loss, and Daily Habits

Regular exercise raises HDL and lowers triglycerides. Aim for at least 150 minutes of moderate activity each week, such as brisk walking, cycling, or swimming. Weight loss also helps, since a loss of 5 to 10 percent of body weight can lower triglycerides by 20 percent or more. If you need support, weight loss management in Cypress offers medically supervised plans.

Quit smoking, since smoking lowers HDL and damages artery walls. HDL can rise by up to 10 percent within weeks of quitting. Limit alcohol to one drink a day for women and two for men, since alcohol raises triglycerides. Better sleep and lower stress also support healthy cholesterol, along with steady blood sugar and blood pressure control over time.
