VLDL, or very-low-density lipoprotein, is a type of lipoprotein made by the liver. It carries triglycerides, a type of fat, in the bloodstream to various tissues in the body. VLDL is one of the five main types of lipoproteins, which also include chylomicrons, LDL, HDL, and IDL. VLDL is considered less dense than other lipoproteins due to its high fat content compared to protein.
VLDL matters for health because high levels of it can lead to an increased risk of cardiovascular diseases. When there is too much VLDL in the blood, it can contribute to plaque buildup in the arteries, which can cause blockages and lead to heart attacks or strokes. Inflammation in the body can raise VLDL levels, making it important to monitor these levels as part of overall heart health.
The primary function of VLDL is to transport triglycerides from the liver to other tissues for energy use or storage. Once VLDL delivers triglycerides, it is converted into LDL (low-density lipoprotein), which is often referred to as “bad cholesterol.” This process is essential for maintaining energy balance in the body, but excess VLDL can disrupt this balance and harm cardiovascular health.
It is important to be aware of VLDL levels in the context of overall health, especially for individuals with risk factors for heart disease. Regular check-ups and blood tests can help assess lipid profiles, including VLDL, to better understand cardiovascular risk and manage health effectively.
