Omega-3 Daily Requirement Calculator

Estimate your personalized omega-3 (EPA + DHA) needs based on age, health status, and fish consumption.

Understanding the Inputs

Collect accurate information for meaningful results

  • Age & Gender: Omega-3 requirements vary by age and gender. Adults typically need 1,000–1,500 mg total (EPA + DHA) daily, with men needing slightly more.
  • Pregnancy Status: Pregnant and breastfeeding women need additional DHA (200–300 mg extra) for fetal brain development and breast milk production.
  • Health Condition: Certain conditions (heart disease, depression, arthritis) may benefit from higher omega-3 intake for therapeutic effects.
  • Fish Consumption: Regular fish consumption (2+ servings per week) significantly reduces supplemental omega-3 needs. Those who never eat fish need more from supplements.
  • Current Intake (optional): Enter your usual daily omega-3 intake from food and supplements to compare with the recommended target.

Complete Guide: Mastering Omega-3 Intake

Evidence-based strategies for cardiovascular and brain health

Omega-3 fatty acids (EPA and DHA) are essential for heart health, brain function, and reducing inflammation. Most adults need 1,000–1,500 mg total daily. Fatty fish (salmon, mackerel, sardines) provide the best sources. Those who don't eat fish should consider high-quality supplements or algae oil (for vegans).

Pregnant and breastfeeding women need additional DHA (200–300 mg extra) for fetal brain development. Higher intakes (1,000–2,000 mg/day) may benefit those with heart disease, depression, or arthritis. Choose purified, third-party tested supplements to avoid contaminants.

Frequently Asked Questions

Omega-3 fundamentals and best practices

What are omega-3 fatty acids?

Omega-3s are essential polyunsaturated fats your body cannot produce. The main types are EPA (heart/brain), DHA (brain/eye), and ALA (plant sources that convert to EPA/DHA).

How much omega-3 do adults need each day?

Most adults need 1,000–1,500 mg total (EPA + DHA) daily. Men typically need slightly more (1,000–1,500 mg) than women (800–1,200 mg). Higher intakes may benefit those with heart disease or inflammation.

What is the difference between EPA and DHA?

EPA supports cardiovascular health and reduces inflammation. DHA is critical for brain function, eye health, and fetal development. Both are found in fatty fish and fish oil supplements.

Which foods are highest in omega-3?

Fatty fish (salmon, mackerel, sardines, herring) provide EPA and DHA. Plant sources (flaxseeds, chia seeds, walnuts) provide ALA, which converts to EPA/DHA at low rates (5–10%).

Can I get enough omega-3 from plants alone?

Plant sources (ALA) convert poorly to EPA/DHA. Vegans should consider algae oil supplements (rich in DHA) or focus on maximizing ALA intake from flax, chia, and walnuts.

Do omega-3 supplements have side effects?

High doses (>3,000 mg/day) may cause fishy aftertaste, gastrointestinal upset, or increased bleeding risk. Start with lower doses and take with meals to minimize side effects.

How do omega-3s benefit heart health?

Omega-3s reduce triglycerides, lower blood pressure, decrease inflammation, and may reduce arrhythmia risk. The American Heart Association recommends 1,000 mg/day for heart disease prevention.

Can omega-3 help with depression?

Some studies suggest EPA-rich omega-3 supplements may support mood and reduce depressive symptoms, especially when combined with standard treatments. Consult a healthcare provider.

Should pregnant women take omega-3 supplements?

Yes. Pregnant and breastfeeding women need 200–300 mg additional DHA daily for fetal brain development. Choose high-quality, purified fish oil or algae supplements to avoid contaminants.

How often should I reassess my omega-3 intake?

Review every few months or when health conditions, fish consumption patterns, or pregnancy status changes. Blood omega-3 index testing can assess actual tissue levels.
