How Omega-3 Fish Oil Helps with Depression
Omega-3 fatty acids (especially EPA) support brain cell membrane fluidity and reduce neuroinflammation, which is increasingly linked to depression. EPA appears to be more effective than DHA for mood disorders.
🔬 What the Research Says
A 2019 meta-analysis in Translational Psychiatry analyzing 26 studies found omega-3 supplementation (particularly EPA-predominant formulas) had a significant antidepressant effect, especially as an adjunct to standard antidepressant therapy.

📋 How to Use
Take fish oil capsules with meals to reduce fishy aftertaste. Choose a supplement with a high EPA-to-DHA ratio. Combine with a diet rich in fatty fish (salmon, sardines, mackerel).
💊 Recommended Dosage
1-2 grams of EPA per day. Look for supplements providing at least 60% EPA. Effects typically noticed within 4-8 weeks.
⚠️ Side Effects & Cautions
Fish oil burps, GI upset at high doses. May increase bleeding risk in those on blood thinners. High-quality supplements minimize contaminant concerns.
