Frequently asked questions
How much omega-3 DHA+EPA should I take daily?
The American Heart Association recommends 250–500mg of combined DHA+EPA daily. Your individual needs may vary based on age, current diet, and health status.
What's the difference between DHA and EPA?
DHA (docosahexaenoic acid) supports brain and eye function, while EPA (eicosapentaenoic acid) supports heart and mood health. Both are omega-3 fatty acids found mainly in fatty fish.
Do I need omega-3 supplements?
If you eat fatty fish 2–3 times per week, you may meet your omega-3 needs through diet. If not, supplements can help you reach daily recommendations.
Can you take too much omega-3?
While omega-3 is generally safe, very high doses may increase bleeding risk. Don't exceed 3,000mg daily without consulting your healthcare provider.
What foods are high in omega-3?
Fatty fish (salmon, mackerel, sardines), walnuts, flaxseeds, chia seeds, and algae are excellent sources of DHA and EPA.
Is this calculator medically accurate?
This is a reference tool based on AHA guidelines and population studies. For medical advice, consult a healthcare professional—individual needs vary significantly.
When should I see a doctor about omega-3 intake?
See a healthcare provider if you have heart disease, take blood-thinning medications, or are unsure about your omega-3 needs.
When's the best time to take omega-3 supplements?
Omega-3 supplements are best taken with meals to improve absorption and reduce digestive discomfort.
