Several options can lower high triglycerides, ranging from dietary changes and exercise to prescription medications that can cut levels by 30% to 50%. The right approach depends on how elevated your numbers are. Normal triglycerides fall below 150 mg/dL, while levels of 150 to 199 are considered mild, 200 to 499 moderate, and anything above 500 severe.
Lifestyle Changes Come First
For mild to moderate elevations, lifestyle changes are the starting point and sometimes the only intervention needed. Your liver converts excess calories, especially from sugar and alcohol, directly into triglycerides. That makes these two dietary targets disproportionately effective compared to other changes.
Cutting back on added sugars, refined carbohydrates (white bread, pastries, sugary drinks), and alcohol can produce noticeable drops in triglyceride levels within weeks. Alcohol is particularly potent at raising triglycerides because the liver prioritizes processing it over other fats, causing a temporary spike that becomes chronic with regular drinking. Even moderate alcohol use can keep triglycerides elevated in people who are sensitive to it.
Regular aerobic exercise, even without weight loss, lowers triglycerides by helping your muscles burn circulating fat for fuel. Losing excess weight amplifies the effect. Replacing saturated fats with unsaturated fats (olive oil, nuts, avocados, fatty fish) also helps shift the balance.
Prescription Omega-3 Fatty Acids
The American Heart Association recognizes prescription omega-3 supplements at a dose of 4 grams per day as an effective triglyceride-lowering treatment. These are not the same as the fish oil capsules you find at the pharmacy. Prescription formulations contain concentrated EPA (one of the two active fats in fish oil), either alone or combined with DHA, at doses far higher than any over-the-counter product delivers.
The most well-studied prescription omega-3, a purified EPA product, was tested in over 8,000 patients in the REDUCE-IT trial, where participants took 4 grams daily for nearly five years. The trial found significant reductions in cardiovascular events. These products can be used alone or alongside other cholesterol-lowering medications, and they’re typically prescribed when triglycerides remain elevated despite lifestyle changes.
Over-the-counter fish oil supplements contain much lower concentrations of EPA and DHA. You’d need to take a large number of capsules to approach the prescription dose, and doing so introduces unnecessary calories and potential contaminants. If your levels are high enough to need omega-3 therapy, the prescription version is what works reliably.
Fibrates
Fibrates are the most powerful class of triglyceride-lowering drugs available for most patients. They work by activating a protein in your cells that controls how your body processes and clears fat from the bloodstream. In people with moderate elevations (under 500 mg/dL), fibrates typically reduce triglycerides by 30% to 50%.
These medications are often prescribed when triglycerides are stubbornly high despite diet changes, or when levels reach the severe range where there’s a real risk of pancreatitis, a painful and potentially dangerous inflammation of the pancreas. For people already taking a statin for cholesterol, adding a fibrate is sometimes considered. The combination does carry a slightly increased risk of muscle pain and damage, though the actual incidence of serious muscle problems is low, roughly 0.12% in clinical studies.
Statins
Statins are best known for lowering LDL cholesterol, but they also reduce triglycerides by 10% to 30%. That secondary benefit makes them a practical choice when someone has both high cholesterol and moderately elevated triglycerides. For people whose triglycerides are the primary problem rather than a side issue, statins alone usually aren’t enough, but they contribute meaningfully as part of a broader strategy.
Why Niacin Has Fallen Out of Favor
Niacin (vitamin B3) was once a standard recommendation for high triglycerides. At doses of 1,500 to 2,000 milligrams per day, it can lower triglycerides and raise HDL (“good”) cholesterol. But its reputation has deteriorated significantly over the past decade.
A major study of more than 25,000 patients found that adding niacin to statin therapy provided little additional benefit. More concerning, high-dose niacin was linked to a higher risk of developing diabetes, worsened blood sugar control in people who already had it, and serious gastrointestinal problems requiring hospitalization. In 2016, the FDA withdrew its approval for using niacin alongside statins or other lipid-lowering drugs. More recently, researchers found that breakdown products of excess niacin in the blood were associated with an increased risk of heart attack and stroke. Given these risks and the lack of proven benefit for preventing cardiovascular events, niacin is rarely recommended today.
Treatments for Severe Cases
When triglycerides climb above 500 mg/dL, the treatment priority shifts from cardiovascular risk to preventing pancreatitis. At these levels, standard medications like fibrates and prescription omega-3s are used more aggressively, and dietary fat restriction becomes critical.
For people with genetic conditions that push triglycerides to extreme levels, such as familial chylomicronemia syndrome (where levels can exceed 750 mg/dL), newer injectable medications have been developed. These drugs work by blocking a specific protein your liver produces that normally slows the clearance of fat from your blood. By silencing that protein, the body clears triglyceride-rich particles much more efficiently. These treatments are reserved for severe, genetically driven cases that don’t respond adequately to conventional therapy.
Choosing the Right Approach
The path forward depends largely on your numbers and overall cardiovascular risk. Mild elevations (150 to 199 mg/dL) often respond well to cutting sugar and alcohol, exercising more, and losing weight if needed. Moderate levels (200 to 499 mg/dL) may require medication, particularly if lifestyle changes haven’t brought numbers down or if you have other risk factors like diabetes or existing heart disease. Severe levels (above 500 mg/dL) almost always require medication to reduce the near-term risk of pancreatitis.
Your provider will likely recheck your triglycerides with a fasting blood test after you’ve had time to respond to whatever treatment you start. Since triglycerides fluctuate more than cholesterol from day to day, a single reading doesn’t always tell the full story. Consistency matters: a sustained pattern of improvement is more meaningful than any one lab result.
