Vldl vs. Ldl — What's the Difference?
By Fiza Rafique & Urooj Arif — Updated on May 8, 2024
VLDL (Very Low-Density Lipoprotein) primarily transports triglycerides from the liver to tissues; LDL (Low-Density Lipoprotein), known as "bad cholesterol," mainly carries cholesterol to tissues, raising heart disease risk.

Key Differences
VLDL and LDL are both lipoproteins, but they differ significantly in their primary cargo. VLDL mainly carries triglycerides, which are fats used for energy or stored by the body, while LDL primarily transports cholesterol, crucial for cell membranes and hormone production. This difference in cargo affects how they influence cardiovascular health.
VLDL particles are produced by the liver and are initially rich in triglycerides. As they circulate in the bloodstream, these triglycerides are gradually delivered to various body tissues. On the other hand, LDL is formed as a byproduct when VLDL loses triglycerides; it becomes denser and richer in cholesterol.
The role of LDL in cardiovascular health is more prominent. High levels of LDL cholesterol are associated with an increased risk of atherosclerosis, where arteries are clogged by fatty deposits. In contrast, VLDL's impact on heart health is linked to its triglyceride content, which can also contribute to atherosclerosis if levels are excessively high.
Both VLDL and LDL are measured in blood tests to assess cardiovascular risk, but LDL levels are often given more attention in medical assessments. Whereas LDL is directly linked to the risk of heart attacks and strokes, VLDL is considered in the broader context of triglyceride levels.
Despite their roles in transporting different substances, both VLDL and LDL need to be kept within healthy levels to maintain cardiovascular health. Managing diet, exercising, and sometimes medications are recommended to control their levels in the blood.

Compare with Definitions
Vldl
A lipoprotein that carries triglycerides from the liver to tissues.
VLDL levels in the blood can indicate how the body handles fat.
Ldl
Known as "bad cholesterol," it transports cholesterol to body tissues.
High LDL levels are linked to an increased risk of heart disease.
Vldl
A precursor to LDL in the lipid metabolism process.
VLDL converts into LDL, increasing the cholesterol content.
Ldl
More directly linked to cardiovascular diseases.
Monitoring LDL is essential for heart health maintenance.
Vldl
Assessed as part of lipid profile tests.
Elevated VLDL can be a risk factor for metabolic syndrome.
Ldl
Lowering LDL is a key focus of dietary and pharmaceutical treatment.
Statins are prescribed to reduce LDL levels.
Vldl
Very Low-Density Lipoprotein involved in the transport of fats.
Doctors check VLDL to assess fat metabolism.
Ldl
Low-Density Lipoprotein that can deposit cholesterol in artery walls.
Reducing LDL is crucial for preventing atherosclerosis.
Vldl
Affects cardiovascular health indirectly through triglyceride transport.
High VLDL levels can also contribute to heart disease.
Ldl
Directly measured in standard cholesterol tests.
LDL levels are a primary target in cholesterol management.
Ldl
A lipoprotein with a relatively high proportion of lipids and low proportion of protein that incorporates cholesterol and transports it to cells. High levels are associated with an increased risk of atherosclerosis and coronary artery disease. Also called LDL cholesterol.
Common Curiosities
What is VLDL?
VLDL stands for Very Low-Density Lipoprotein, a type of lipoprotein that transports triglycerides from the liver to various tissues in the body.
What does LDL stand for?
LDL stands for Low-Density Lipoprotein, often referred to as "bad cholesterol" because it transports cholesterol to tissues and can lead to artery clogging.
What diet changes can help reduce LDL levels?
Eating more fiber, avoiding trans fats, and reducing saturated fat intake can help lower LDL levels.
How are VLDL and LDL related?
LDL is formed from VLDL as triglycerides are removed and it becomes richer in cholesterol.
Why is LDL considered more harmful than VLDL?
LDL contributes more directly to the buildup of fatty deposits in arteries, increasing the risk of heart disease and strokes.
Can VLDL levels affect heart health?
Yes, elevated VLDL levels, due to their triglyceride content, can contribute to the development of heart disease, though less directly than LDL.
What role does the liver play in VLDL and LDL production?
The liver produces VLDL, which later converts into LDL as it loses triglycerides and increases in cholesterol content.
What medications are commonly used to lower LDL?
Statins are the most common medications prescribed to reduce LDL levels effectively.
Are there any symptoms of high LDL or VLDL levels?
There are usually no symptoms; high levels are typically discovered through blood tests.
Is there a genetic component to high LDL and VLDL levels?
Yes, genetics can play a significant role in determining individual levels of VLDL and LDL.
How do VLDL and LDL levels affect the risk for diabetes?
While LDL is less directly linked to diabetes, high VLDL levels can be a part of metabolic syndrome, which includes insulin resistance, a precursor to diabetes.
How can one lower high VLDL levels?
Reducing intake of carbohydrates and fats, increasing physical activity, and sometimes medications can help lower VLDL levels.
How often should one check their VLDL and LDL levels?
Regular check-ups depend on individual risk factors for heart disease; doctors can provide personalized recommendations.
Can exercise affect VLDL and LDL levels?
Regular exercise can help lower both VLDL and LDL levels by improving overall fat metabolism.
Can children have high LDL and VLDL levels?
Yes, children can also have elevated lipoprotein levels, which is why early dietary habits are important.
