How much omega-3 should you take for dry eyes? Research commonly evaluates between 1,000 and 3,000 milligrams of combined EPA and DHA daily, but the benefits can vary depending on the person, dosage, supplement quality and type of dry eye disease.
On the Doctor Eye Health Podcast, Dr. Joseph Allen examines the research behind omega-3 fatty acids for dry eye relief. He explains how omega-3s may help reduce inflammation, improve tear film stability and support healthier meibomian gland secretions.
You will learn the difference between EPA, DHA and plant-based ALA, why the amount of fish oil listed on the front of a bottle can be misleading and how re-esterified triglyceride supplements compare with ethyl ester forms. Dr. Allen also discusses omega-3 testing, dietary sources, absorption and supplement safety.
Although omega-3s may benefit some people with dry eye, they are not a cure or standalone treatment. Dry eye disease is complex and often requires a personalized plan that may include lubricating drops, eyelid care, environmental changes, prescription medications and in-office treatments.

Key Takeaways
🔹 Research commonly evaluates between 1,000 and 3,000 milligrams of combined EPA and DHA daily for dry eye, but results are mixed and individual responses vary.
🔹 Look at the EPA and DHA amounts on the supplement facts label rather than relying on the total fish oil amount printed on the front of the bottle.
🔹 Fatty fish such as salmon, mackerel, anchovies, sardines and herring provide natural sources of EPA and DHA. Algae-based omega-3 is an alternative for people who do not consume fish.
🔹 Omega-3 should be considered one part of a comprehensive dry eye treatment plan. Speak with a healthcare professional before taking higher doses, especially if you use blood thinners, have atrial fibrillation, are preparing for surgery, are pregnant or breastfeeding or have a fish allergy.
