About this calculator
The Omega-3 EPA+DHA Calculator estimates daily intake of essential fatty acids EPA (Eicosapentaenoic Acid) and DHA (Docosahexaenoic Acid), crucial for brain, heart, and inflammation health. It uses a formula of 1.5mg/g of fish consumed, assuming fish is the primary source. Recommended intake is 250, 500mg/day, though individual needs may vary based on health conditions.
It works by inputting daily fish consumption in grams, then calculating EPA+DHA content using the 1.5mg/g ratio. For example: 50g of salmon (rich in omega-3) provides ~75mg of EPA+DHA. The result indicates whether dietary intake meets recommendations, serving as a foundation for diet planning, supplementation, or adjustments. Note that other sources like flaxseed or capsules also contribute to daily needs.
Use this calculator to plan omega-3 intake, especially if following plant-based diets, vegetarianism, or fish restrictions. It helps pregnant individuals, the elderly, or those with heart conditions. Adjust diet based on results: supplement if deficient or reduce excess. Children, athletes, or medical cases should consult a nutritionist before changing intake.
Cautions: Do not exceed 3,000mg/day of omega-3 without medical advice, as high doses may affect blood clotting. The calculator assumes fish is the primary source; if other sources (like fortified eggs) are used, adjust manually. It also doesn’t account for individual absorption variations due to genetics or medications.

How to use the Omega-3 EPA+DHA Calculator?
Enter your daily fish consumption in grams. The calculator uses 1.5mg/g to estimate EPA+DHA intake. Compare the result to the 250, 500mg/day recommendation.
What is the difference between Omega-3 and EPA+DHA?
Omega-3 is a group of essential fatty acids, including ALA (plant-based), EPA, and DHA (fish). The calculator focuses on EPA+DHA, which are more bioavailable and linked to heart and cognitive benefits.
Can I use the calculator if I don’t eat fish?
Yes, but the calculation assumes fish is the primary source. If you consume other sources like flaxseed or supplements, adjust intake manually or consult a nutritionist for personalized needs.
How many fish portions per day are needed?
To reach 250, 500mg of EPA+DHA, eat 167, 333g of fish daily (based on 1.5mg/g). Variations depend on fish type and preparation methods.
Do I need supplements if I meet the recommendation?
Not necessarily. If your diet is balanced, supplements may be optional. However, in cases of dietary restrictions, deficiency, or higher needs, consult a doctor.
