What is the role of omega-3 fatty acids in triglyceride management?

Omega-3 fatty acids lower triglycerides by reducing hepatic VLDL production, which decreases the amount of triglyceride carried in the blood. In the liver, these fats reduce triglyceride synthesis and VLDL assembly while increasing fatty acid oxidation, so fewer TG-rich VLDL particles are released into circulation. The resulting drop in circulating VLDL translates to lower fasting triglyceride levels. This mechanism explains their use in severe hypertriglyceridemia. They don’t work by inhibiting HMG-CoA reductase (that’s statins) and they don’t reliably produce a large, consistent increase in HDL-C; they can cause a small, variable change in LDL-C in some individuals, but the major triglyceride-lowering effect comes from decreased hepatic VLDL output.
