Omega-3 Dose Calculator
Choose a goal to compare common EPA+DHA amounts. Count EPA plus DHA on the label, not the total fish-oil weight.
How to read your result
- Start with Your dose and How to split; this is a comparison point, not a prescription.
- Check the Evidence range / upper limit and safety cautions.
- Weight, age and sex are not dose inputs unless the result explicitly says they are.

Medication & safety cautions
- Ask your clinician before higher-dose omega-3 if you take an anticoagulant or antiplatelet medicine.
- Higher supplemental doses have been associated with a small increase in atrial fibrillation risk; discuss doses above 1 g/day, particularly if you have an arrhythmia history.
How this estimate works
Heart/brain: 1,000 mg EPA+DHA daily. High triglycerides: 2,000 mg/day in this estimate; 2–4 g/day requires a doctor. Mood: 1,500 mg/day of an EPA-rich product (at least 60% EPA). Take with meals and split amounts above 1,000 mg. EFSA/FDA consider up to 5,000 mg/day safe for most adults; personal risks differ.

Frequently asked questions
Does the dose mean fish-oil weight?
No. It means combined EPA plus DHA. The total fish-oil amount on the front of a bottle can be much higher than its EPA+DHA content.
Can I use omega-3 for high triglycerides?
Prescription-level doses may be used for triglycerides, but the 2–4 g/day range should be supervised by a clinician; this tool is not a treatment recommendation.
What changes during pregnancy?
The reference shown is 1,000 mg/day EPA+DHA including 200–300 mg DHA. Discuss products and dosing with your obstetric clinician.
