 Recent research suggests that the optimal intake of omega-3 fatty acids—especially EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid)—may be higher than previously recommended for supporting not just heart health, but also brain function, mood regulation, metabolic health, and inflammation control.

Key Insights:

1. Traditional Recommendations Are Minimal, Not Optimal

Agencies like the WHO and EFSA often recommend 250–500 mg/day of EPA + DHA for adults.

However, these levels are baseline for deficiency prevention—not for optimal performance or long-term health protection.

2. Emerging Evidence Supports Higher Intakes

New studies show benefits at higher daily intakes:

1,000–2,000 mg/day of EPA+DHA for cardiovascular and metabolic protection.

Doses up to 3,000–4,000 mg/day used in clinical settings for lowering triglycerides, inflammation, or mood disorders.

Athletes, pregnant women, individuals with mental health conditions, and those on inflammatory or carb-heavy diets may need significantly more.

3. The Omega-3 Index as a Marker

A more accurate way to gauge adequacy is through the Omega-3 Index (RBC membrane EPA+DHA %).

Target index: 8–12% (most people are below 4%).

People in Japan and coastal populations often reach these optimal ranges through diet alone (e.g., high seafood intake).

4. Modern Diets Are Severely Skewed

High omega-6 to omega-3 ratio (often >15:1) in Western diets contributes to chronic inflammation.

Rebalancing this ratio through higher omega-3 intake (from fish, krill oil, algae oil, grass-fed meats) is now considered crucial.

Summary:

> Modern optimal omega-3 intake may be closer to 1,000–3,000 mg of EPA+DHA daily, especially for those seeking:

Cognitive support

Anti-inflammatory effects

Cardiovascular protection

Hormonal and emotional balance
