Omega-3 Fatty Acids
& Fatty Liver Disease

What the science says — and what it means for your liver health

Fatty liver disease (MASLD) affects 1 in 4 adults worldwide — and the connection to what we eat is profound. Omega-3 fatty acids are among the most studied nutritional interventions for liver health. Here is what you need to know.

What is Fatty Liver Disease?

Metabolic-associated steatotic liver disease (MASLD — formerly NAFLD) occurs when excess fat accumulates in liver cells, often driven by insulin resistance, visceral adiposity, and poor dietary fat quality. Left unaddressed, it can progress from simple steatosis to inflammation (MASH), fibrosis, and cirrhosis. Crucially, it is both preventable and reversible with the right metabolic interventions.

How omega-3s work in the liver

Reduces De Novo Lipogenesis

EPA & DHA suppress SREBP-1c — the key transcription factor that drives the liver to make new fat from carbohydrates.

🔥

Boosts Fat Oxidation

Activates PPAR-α, shifting the liver from fat storage toward fat burning via mitochondrial beta-oxidation pathways.

🛡️

Anti-Inflammatory Action

Resolvin and protectin synthesis from EPA/DHA actively resolves hepatic inflammation — critical in MASH progression.

📉

Lowers Triglycerides

Inhibits VLDL-TG secretion and increases lipoprotein lipase activity, reducing circulating and stored liver triglycerides.

🧬

Improves Insulin Sensitivity

Enhances adiponectin signalling and reduces hepatic inflammation, both of which directly improve insulin receptor function.

🦠

Modulates the Gut-Liver Axis

Promotes a healthier gut microbiome composition, reducing lipopolysaccharide translocation and liver immune activation.

Clinical Evidence

Therapeutic Range

Liver health (general) 2–4 g/day
Triglyceride lowering 3–4 g/day
Anti-inflammatory 2–3 g/day
Preferred form EPA+DHA
Minimum ratio EPA ≥ DHA

Food-First Approach

🐟 Fatty fish — salmon, mackerel, sardines (2–3×/week)
🥜 Walnuts & flaxseed (ALA — precursor to EPA/DHA)
🌿 Chia seeds & hemp seeds (plant-based ALA)
🦐 Anchovies, herring, and mussels
💊 High-quality fish oil or algae-based supplements
⚠️

Important Considerations

High-dose omega-3 supplementation (>3 g/day) may increase bleeding risk — discuss with your doctor if you are on anticoagulants. Oxidised fish oil supplements may be pro-inflammatory; choose third-party tested, high-purity products. Omega-3s are an adjunct to — not a replacement for — dietary change, exercise, and metabolic optimisation.
