Fish Oil for Fatty Liver: Can Omega-3 Help NAFLD and MASLD?

Fatty liver is increasingly common, and many people looking for ways to support liver health come across fish oil and omega-3 supplements. But does fish oil actually help fatty liver?

The short answer is: omega-3 may have some useful effects in people with fatty liver, but fish oil is not a cure and should not replace medical care or lifestyle changes. Research is promising in some areas, especially blood triglycerides and certain measures of liver health, but results are not completely consistent.

It is also worth knowing that NAFLD is now commonly referred to as MASLD—metabolic dysfunction-associated steatotic liver disease. The 2024 EASL-EASD-EASO guideline uses MASLD as the current term for fatty liver associated with metabolic risk factors. Learn more about the current MASLD definition and clinical guidance.

What Is Fatty Liver and NAFLD?

Fatty liver means excess fat has accumulated in the liver. When this occurs in the context of metabolic risk factors and without harmful alcohol intake, it is now generally described as MASLD. The older term NAFLD—non-alcoholic fatty liver disease—is still widely used in searches and everyday conversation.

MASLD can range from simple liver fat accumulation to more serious disease involving inflammation, fibrosis and cirrhosis. Having fatty liver does not automatically mean that a person will develop advanced liver disease, but it deserves appropriate evaluation.

Can Fish Oil Help Fatty Liver?

Fish oil provides omega-3 fatty acids, mainly EPA and DHA. Researchers have studied omega-3 supplements in people with NAFLD and MASLD because omega-3 fatty acids can influence lipid metabolism and blood triglycerides.

The evidence suggests that omega-3 supplementation may improve some metabolic and liver-related markers in certain people. However, it is too strong to say that fish oil removes fatty liver or reverses liver disease on its own.

A 2025 meta-analysis of 20 randomized controlled trials involving 1,615 adults found that omega-3 supplementation improved GGT and was associated with improved ultrasound-assessed hepatic steatosis, but it did not show significant improvements in ALT, AST, MRI-based liver fat, liver stiffness or histology. The researchers also noted substantial heterogeneity and called for better trials. Read the 2025 meta-analysis. citeturn0search3

How Might Omega-3 Work?

1. It can influence triglyceride metabolism

One of the better-established effects of EPA and DHA supplementation is on blood triglycerides. This matters because high triglycerides commonly occur alongside metabolic dysfunction and fatty liver.

A 2025 meta-analysis of randomized trials of fish oil in MASLD found improvements in triglycerides, AST, insulin resistance and waist circumference, although several other outcomes—including ALT—did not significantly improve. Review the fish oil and MASLD evidence. citeturn0search13

2. Omega-3 may affect liver fat metabolism

Omega-3 fatty acids are involved in lipid metabolism. This is one reason researchers have investigated whether supplementation can reduce fat stored in the liver. Some studies show improvements, while others do not, so the effect should be described as possible rather than guaranteed.

3. It may support a healthier metabolic profile

Fatty liver is closely connected with metabolic health. Diet quality, body weight, physical activity, blood glucose and blood lipids all matter. Omega-3 may be one small part of that bigger picture.

What Does the Research Actually Say?

The evidence has evolved over time. Earlier reviews suggested potential improvements in liver fat and liver enzymes, while newer analyses have found mixed results across different measures.

An umbrella meta-analysis published in 2023 reported improvements in ALT, AST, GGT and liver fat with omega-3 polyunsaturated fatty acids. However, a newer 2025 meta-analysis found a more limited pattern of benefit, with improvements in GGT and ultrasound-assessed steatosis but not several MRI or histology outcomes. These differences show why it is better to say omega-3 may help some aspects of fatty liver rather than claiming it is a treatment or cure. citeturn0search7turn0search3

Fish Oil Is Not a Stand-Alone Treatment for Fatty Liver

This is the most important point.

Current MASLD guidance emphasizes a comprehensive approach to metabolic health rather than relying on one supplement. Management can involve improving diet quality, increasing physical activity, addressing excess body weight when appropriate, and managing metabolic risk factors under medical guidance. citeturn0search4turn0search9

If you have been diagnosed with fatty liver, do not stop prescribed medicines or replace your treatment plan with fish oil.

Can Omega-3 Help With Triglycerides in People With Fatty Liver?

Potentially, yes. Omega-3 supplements are particularly relevant because EPA and DHA can lower blood triglycerides in appropriate doses. The 2025 fish-oil meta-analysis in MASLD found a significant improvement in triglycerides. citeturn0search13

However, the right dose depends on the specific goal and individual health situation. A supplement label should be assessed based on its EPA and DHA content rather than only the total amount of fish oil.

How to Choose Fish Oil for Fatty Liver

If a healthcare professional has recommended omega-3 supplementation, compare products carefully.

• Check EPA and DHA: Do not judge a product only by the total fish oil amount.
• Check the serving size: See how many capsules provide the stated EPA and DHA.
• Choose transparent labeling: The source, ingredients and usage instructions should be easy to understand.
• Consider quality and freshness: Follow storage instructions and choose a reputable manufacturer.
• Don't assume more is better: Higher doses should be used only when appropriate and with professional guidance.

Lifestyle Changes Matter More Than Any Single Supplement

If you have fatty liver, think beyond supplements. Regular physical activity, a balanced diet, appropriate weight management, good sleep and management of blood sugar and blood lipids can all be important parts of metabolic health.

For many people, the practical goal is not to find one “fatty liver supplement,” but to build a sustainable routine that addresses the factors contributing to liver fat.

Frequently Asked Questions

Does fish oil cure fatty liver?

No. Current evidence does not support presenting fish oil as a cure for fatty liver. Omega-3 may improve some metabolic or liver-related markers, but it should be considered an adjunct to appropriate lifestyle and medical management.

Is fish oil good for NAFLD?

Omega-3 supplementation may help some people with NAFLD/MASLD, particularly with triglycerides and some measures of steatosis. However, research results are mixed, and benefits are not guaranteed.

How much fish oil should I take for fatty liver?

There is no single dose that is appropriate for everyone with fatty liver. The amount depends on the EPA and DHA content, the reason for supplementation, medications and individual health factors. Follow professional advice and the product label.

Is EPA or DHA better for fatty liver?

Both EPA and DHA are omega-3 fatty acids, and studies often evaluate them together. There is not enough evidence to say that one is universally better for fatty liver.

Can I take fish oil if I have fatty liver?

Some people can, but a healthcare professional should guide supplementation if you have diagnosed liver disease, take medicines, have a bleeding disorder, have an upcoming procedure or have other medical concerns.

Conclusion:

Fish oil and omega-3 are promising but should not be oversold as a fatty liver treatment. Current research suggests omega-3 supplementation may improve triglycerides and some measures of steatosis in people with NAFLD/MASLD, while other outcomes remain uncertain.

If you have fatty liver, the strongest strategy is a complete approach to metabolic health, with supplements used only when they make sense for your individual situation.
