The VLDL (Very Low-Density Lipoprotein) Calculator estimates VLDL cholesterol from triglyceride levels using the standard formula VLDL = Triglycerides / 5. VLDL particles are triglyceride-rich lipoproteins produced by the liver that serve as precursors to LDL. Elevated VLDL contributes independently to atherosclerosis and cardiovascular disease through mechanisms distinct from LDL cholesterol.
VLDL particles are synthesized in the liver and carry primarily triglycerides with some cholesterol. In the bloodstream, lipoprotein lipase hydrolyzes VLDL triglycerides, progressively converting VLDL to IDL (intermediate-density lipoprotein) and ultimately to LDL. VLDL remnants can penetrate the arterial wall and promote foam cell formation and atherosclerosis, independent of LDL pathways.
Normal VLDL cholesterol is below 30 mg/dL. The standard estimation method divides fasting triglycerides by 5 (in mg/dL units) based on the observation that the TG:cholesterol ratio in VLDL averages approximately 5:1 in fasting individuals. This method is reasonably accurate when triglycerides are below 400 mg/dL but becomes progressively less reliable with higher triglyceride levels due to altered VLDL composition.
Elevated VLDL is common in metabolic syndrome, type 2 diabetes, obesity, excessive alcohol intake, and high-carbohydrate diets. These conditions increase hepatic triglyceride synthesis and VLDL secretion. VLDL overproduction also leads to increased small dense LDL particles (pattern B), which are more atherogenic than large buoyant LDL, creating a particularly harmful lipid environment.
Treatment of elevated VLDL focuses on triglyceride reduction: lifestyle modifications including weight loss, exercise, reduced refined carbohydrates and alcohol, and omega-3 fatty acids are first-line. Fibrates (fenofibrate, gemfibrozil) specifically reduce VLDL production and enhance clearance. Statins have modest triglyceride-lowering effects (10-30%) while primarily targeting LDL.
Very high triglycerides above 500 mg/dL represent pancreatitis risk requiring urgent intervention. At these levels, the VLDL estimation becomes unreliable, and the primary clinical concern shifts from cardiovascular risk to acute pancreatitis prevention through aggressive triglyceride lowering.
VLDL = Triglycerides / 5 (mg/dL). For mmol/L input, converted first (TG mmol/L × 88.57 = mg/dL). Normal VLDL: <30 mg/dL. Triglyceride categories per NCEP ATP III.
VLDL <30: normal. 30-40: borderline, monitor. >40: elevated, associated with atherogenic dyslipidemia. TG >500: pancreatitis risk. Formula unreliable above TG 400.

TG 280, VLDL 56 = elevated, associated with metabolic syndrome.
Very low-density lipoprotein cholesterol. VLDL carries triglycerides from the liver and is a precursor to LDL.
VLDL = Triglycerides / 5 (mg/dL). Based on typical 5:1 TG:cholesterol ratio in fasting VLDL particles.
Below 30 mg/dL. No separate VLDL treatment target exists; it is captured in non-HDL cholesterol goals.
Yes. VLDL remnants penetrate arterial walls and promote atherosclerosis independently of LDL through foam cell formation.
At very high TG, VLDL composition changes (higher TG:cholesterol ratio), making the fixed 5:1 division inaccurate.
Obesity, metabolic syndrome, diabetes, high-carbohydrate diet, excessive alcohol, genetic lipid disorders.
Weight loss, exercise, reduced refined carbs and alcohol, omega-3 fatty acids, fibrates. Statins have modest effect on VLDL.
Yes, non-HDL = TC - HDL captures LDL + VLDL + IDL + Lp(a). VLDL is a component of non-HDL cholesterol.
Yes, fasting (9-12 hours) is required for accurate VLDL estimation because triglycerides rise significantly after meals.
VLDL is metabolized to LDL via IDL. High VLDL increases production of small dense LDL, the most atherogenic LDL subtype.
