Get tested with Superpower

If you’ve been postponing blood testing for years or feel frustrated by doctor appointments and limited lab panels, you are not alone. Standard healthcare is often reactive, focusing on testing only after symptoms appear or leaving patients in the dark.

Superpower flips that approach. We give you full insight into your body with over 100 biomarkers, personalized action plans, long-term tracking, and answers to your questions, so you can stay ahead of any health issues.

With physician-reviewed results, CLIA-certified labs, and the option for at-home blood draws, Superpower is designed for people who want clarity, convenience, and real accountability - all in one place.

Key benefits of LDL Cholesterol testing

• Measures "bad" cholesterol that builds plaque and raises heart attack risk.
• Spots elevated cardiovascular risk years before symptoms like chest pain appear.
• Guides statin therapy decisions and tracks whether treatment is lowering LDL effectively.
• Flags familial hypercholesterolemia, a genetic condition causing early heart disease.
• Clarifies stroke risk when combined with blood pressure and diabetes screening.
• Tracks progress after diet, exercise, or medication changes over time.
• Best interpreted with HDL cholesterol, triglycerides, and total cholesterol for complete risk assessment.

What is LDL Cholesterol?

LDL cholesterol stands for low-density lipoprotein cholesterol. It's a package that carries cholesterol through your bloodstream to cells throughout your body. These particles are made primarily in the liver and consist of a fatty core of cholesterol wrapped in a protein shell.

The body's cholesterol delivery system

LDL particles transport cholesterol to tissues that need it for building cell membranes, making hormones, and producing vitamin D. When cells require cholesterol, they pull LDL from the blood using specialized receptors on their surface.

Why LDL earned its reputation

LDL cholesterol is often called "bad cholesterol" because excess particles can infiltrate artery walls. Once inside, they can become oxidized and trigger inflammation, contributing to plaque buildup (atherosclerosis). This process narrows arteries and increases the risk of heart attack and stroke.

The amount of cholesterol carried inside LDL particles reflects how much is circulating in your blood available for delivery - or potentially for deposition in arterial walls.

Why is LDL Cholesterol important?

LDL cholesterol carries fat-based molecules from your liver into your bloodstream, delivering building blocks for cell membranes and hormones. When LDL levels climb too high, these particles infiltrate artery walls, triggering inflammation and plaque formation that narrows blood flow to your heart, brain, kidneys, and limbs. This biomarker predicts your long-term risk for heart attack and stroke more powerfully than almost any other single lab value.

When LDL runs lower than expected

Values below 70 mg/dL are generally considered protective against cardiovascular disease, especially for people with prior heart events. Very low readings - under 40 - are uncommon without medication and rarely cause symptoms on their own. In these cases, your body still produces enough cholesterol internally for hormone synthesis and cell repair.

When LDL climbs into risky territory

Levels above 130 mg/dL begin to accelerate plaque buildup in coronary and carotid arteries, a process called atherosclerosis. You won't feel chest pain or fatigue until blockages become severe, which is why elevated LDL is often called a "silent" risk. Women before menopause tend to have lower LDL than men due to estrogen's protective effects, but that advantage fades after menopause when cardiovascular risk equalizes.

The bigger cardiovascular picture

LDL works in concert with HDL cholesterol, triglycerides, blood pressure, and blood sugar to shape your overall metabolic health. Chronic elevation drives not only coronary disease but also peripheral artery disease, chronic kidney damage, and cognitive decline over decades. Monitoring LDL helps you understand how your liver, diet, genetics, and lifestyle converge to influence lifelong vascular integrity.

What do my LDL Cholesterol results mean?

Low LDL cholesterol

Low values usually reflect reduced cholesterol production in the liver, malabsorption of fats from the gut, or genetic conditions that impair lipoprotein assembly. Very low LDL can occur with malnutrition, advanced liver disease, hyperthyroidism, or rare inherited disorders like abetalipoproteinemia. While lower LDL generally reduces cardiovascular risk, extremely low levels may signal underlying metabolic or absorptive dysfunction that warrants investigation.

Optimal LDL cholesterol

Being in range suggests balanced cholesterol synthesis and clearance, with the liver producing lipoproteins efficiently and receptors removing LDL particles appropriately. For cardiovascular health, optimal LDL tends toward the lower end of the traditional reference range. Most guidelines now emphasize that lower LDL values confer progressively lower risk of atherosclerotic disease, though what constitutes "optimal" depends on individual risk factors and clinical context.

High LDL cholesterol

High values usually reflect increased hepatic production of cholesterol-rich lipoproteins, reduced clearance by LDL receptors, or both. Elevated LDL is strongly associated with atherosclerosis, the process in which cholesterol accumulates in artery walls and drives plaque formation. Common contributors include familial hypercholesterolemia, insulin resistance, hypothyroidism, and diets high in saturated fat. Women often see LDL rise after menopause due to declining estrogen.

Factors that influence LDL cholesterol

LDL fluctuates with fasting status, recent illness, pregnancy, and certain medications including statins, steroids, and hormonal therapies. Assay methods vary slightly between labs, so trends over time within the same laboratory are most informative.
