Dosage

Typical range

500–2,000 mg daily for general health; 2,000–4,000 mg daily for cardiovascular support

Timing

with meals to enhance absorption and reduce gastrointestinal side effects

With food

with food containing dietary fat for optimal bioavailability

Duration

benefits typically appear after 4–12 weeks of consistent supplementation; long-term use is safe

Special Populations

higher doses (2,000+ mg daily) should be discussed with healthcare provider; pregnant/nursing women may benefit from EPA but should confirm dosing with provider

Mechanism of Action

• reduces triglyceride synthesis in the liver
• decreases platelet aggregation and blood clotting
• modulates inflammatory eicosanoid production
• supports neuronal cell membrane integrity and synaptic function

Evidence Quality

Evidence Grade A

Multiple large-scale RCTs (including REDUCE-IT) demonstrate efficacy for triglyceride reduction and cardiovascular outcomes. Consistent evidence for anti-inflammatory effects and cognitive benefits from systematic reviews and meta-analyses.

Safety & Contraindications

Contraindications

• bleeding disorders or use of anticoagulants (warfarin, dabigatran) at very high doses
• fish or seafood allergy (fish oil forms)
• upcoming surgery (may increase bleeding risk at very high doses)

Common Side Effects

• fishy aftertaste
• gastrointestinal upset
• nausea
• loose stools
• mild bruising (rare)

Interactions

💊 Medications

• anticoagulants (warfarin, dabigatran) — increased bleeding risk at high doses; monitor INR
• antiplatelet agents (aspirin, clopidogrel) — additive antiplatelet effect at high doses
• NSAIDs — may increase GI upset risk

🧪 Supplements

• other omega-3 sources (fish oil, flaxseed) — may cause additive effects
