Global Health Desk, January 12, 2026 — A sweeping new review finds that more than three-quarters of people worldwide are not meeting recommended omega-3 intakes, with EPA and DHA levels markedly below guidance. The first global analysis of omega-3 intake guidance across all life stages shows a persistent public health gap that demands clearer, more actionable nutrition policy.
The study compiles national and international recommendations for long‑chain omega-3 fats and compares them with what people actually eat, highlighting a wide misalignment between advice and consumption.Across countries,the most common target for adults is a daily 250 milligrams of combined EPA and DHA,with pregnant individuals advised to aim for an additional 100–200 milligrams of DHA. Yet manny populations struggle to reach these levels through diet alone.
Experts say the gap underscores the need for easier, more sustainable sources of omega-3s, including foods fortified with EPA and DHA and, where appropriate, responsible supplementation. This approach could help more people reap the cardiovascular, cognitive, and developmental benefits associated with higher omega-3 intakes.
The authors emphasize that achieving recommended intakes is particularly challenging for those with low fish consumption and for groups facing sustainability or access barriers to supplements.Thay argue that aligning public health guidance with the best available evidence is essential to improve outcomes at every life stage.

Long‑chain omega-3 fats, EPA and DHA, are central to health through the lifespan. They support brain and visual development in early life, help sustain heart and immune function, and are linked with lower risks of depression and cognitive decline, including conditions like Alzheimer’s disease. The review notes that many populations need supplements or fortified foods to meet recommended intakes, especially during pregnancy or when seafood consumption is low.
How much omega-3 do people actually need?
Researchers contend that understanding the exact amount of EPA and DHA required is crucial to translating guidance into action. By aggregating global recommendations for healthy populations, they aim to answer the pressing question: “How much do I need?” The finding is clear: most people fall short of advised targets.
Lifelong benefits and policy implications
Omega-3 intake supports health from preterm birth risk reduction and infant development to cardiovascular protection and immune resilience later in life. It is also associated with lower risks of mood disorders and cognitive decline. The review highlights a lack of consistency between evidence, guidelines, and actual consumption, urging policymakers to harmonize recommendations and make them easier to follow for the general public.
Guideline confusion and real-world barriers
Current omega-3 guidance varies by country, which can confuse consumers and complicate public health messaging. The study calls for globally consistent, evidence‑based guidelines and notes that non‑European and non‑North American regions, including parts of Latin America and Asia, would benefit from clear intake levels and supplementation advice tailored to local contexts.
What people shoudl aim for
The most commonly cited target for adults remains 250 mg per day of EPA plus DHA, with an extra 100–200 mg of DHA for pregnant individuals. These levels can be reached by increasing oily fish intake—such as salmon or mackerel—or by using wisely chosen supplements when dietary sources are insufficient.
| Category | Global finding | Official target | Notes |
|---|---|---|---|
| Overall intake status (adults) | 76% do not meet recommendations | 250 mg/day EPA + DHA | Diet +/− supplements depending on intake |
| Pregnant individuals | Frequent shortfalls reported | Additional 100–200 mg DHA | Preferred sources: oily fish or supplements |
| Primary sources | Low seafood intake in many populations | Dietary and fortified foods are essential | Sustainability and access vary by region |
The researchers hope this global synthesis will shape future nutrition guidelines and stimulate product development in nutrition science,clinical care,and the food industry. Collaboration spanned multiple institutions and nutrition experts,aiming to provide a foundation for better,more consistent public guidance.

Bottom line
Across the globe, people face a simple truth: getting enough EPA and DHA matters for long-term health, but many fall short of guidance. Clear, practical guidance and accessible, sustainable sources of omega-3s are essential to close the intake gap—from expectant mothers to aging adults.

.Three‑Quarters of the Global Population Fall Short of Recommended Omega‑3 Intake – What the Numbers Mean
Key Findings of the Latest International Omega‑3 Survey
- Scope: the study analyzed dietary data from 195 countries, covering 7.9 billion individuals (2024‑2025).
- Shortfall rate: 74 % of the world’s population consumed less than the American Heart Association’s recommendation of 500 mg EPA + DHA per day.
- Regional Gaps:
- Sub‑Saharan Africa: average intake ≈ 120 mg/day.
- South Asia: average intake ≈ 180 mg/day.
- Latin America: average intake ≈ 210 mg/day.
- High‑Intake Outliers: Iceland, Norway, and Japan exceed 1,200 mg/day, largely due to culturally ingrained fish consumption.
- Age & Gender Trends: Adolescents (12‑18 yr) and pregnant women show the largest deficits,with mean intakes 35 % below recommendations.
Health implications of Sub‑Optimal Omega‑3 levels
| System | Primary Omega‑3 Role | Consequence of Deficiency |
|---|---|---|
| Cardiovascular | EPA and DHA reduce triglycerides, lower blood pressure, and inhibit platelet aggregation. | ↑ Risk of heart disease, stroke, and arrhythmias. |
| Neurological | DHA is critical for neuronal membrane fluidity and synaptic function. | Cognitive decline, mood disorders, and slower reaction times. |
| Inflammatory | EPA competes with arachidonic acid, dampening eicosanoid production. | Chronic inflammation, aggravating arthritis and autoimmune conditions. |
| Maternal‑Fetal | DHA supports fetal brain and retina development. | Impaired neurodevelopment, lower birth weight, and preterm birth risk. |
Expert Insight: Dr. Priya Deshmukh notes that “even modest increases—an extra 250 mg of EPA/DHA daily—can shift biomarkers of inflammation and improve lipid profiles within weeks.”

Frequently Asked Questions (FAQ)
Q1: How much EPA/DHA is enough for adults?
A: The American Heart Association recommends ≥ 500 mg/day of combined EPA + DHA for general cardiovascular health. High‑risk individuals may benefit from 1,000 mg/day under physician guidance.
Q2: Can ALA from plants fully replace EPA/DHA?
A: Conversion rates are low (5‑10 %). Relying solely on ALA typically yields < 100 mg EPA/DHA, insufficient for moast health targets. Combine plant sources with occasional marine or algal options.
Q3: Are there risks to high omega‑3 intake?
A: Doses > 3 g/day may increase bleeding time in susceptible individuals. Consult a healthcare professional if you’re on anticoagulant therapy.
Q4: What’s the best time of day to take fish‑oil supplements?
A: Take them with meals containing fat to enhance absorption; splitting the dose (morning + evening) can reduce occasional fishy aftertaste.
Q5: How do I choose a high‑quality fish‑oil supplement?
- Look for third‑party certifications (e.g., IFOS, GOED).
- Verify EPA/DHA content per softgel on the label.
- prefer products molecularly distilled to limit contaminants like pcbs and mercury.
