Very Low-Density Lipoprotein, or VLDL, is a type of lipoprotein produced by the liver. It primarily carries triglycerides, a type of fat, through the bloodstream to various tissues in the body. VLDL is considered one of the "bad" cholesterol types because high levels can lead to plaque buildup in arteries, increasing the risk of heart disease. VLDL is classified based on its density, which is lower than that of LDL (Low-Density Lipoprotein) and HDL (High-Density Lipoprotein). When VLDL delivers triglycerides to cells, it transforms into LDL, further contributing to cholesterol levels in the body. Monitoring VLDL levels is important for maintaining cardiovascular health.
