About the Fish Oil Dosage Calculator
The Fish Oil Dosage calculator provides evidence-based EPA+DHA intake recommendations tailored to your health profile and life stage. Omega-3 fatty acids EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) are essential polyunsaturated fats with wide-ranging physiological functions including cardiovascular protection, anti-inflammatory action, brain and neurological support, and fetal development. The Western diet is typically deficient in omega-3 fatty acids relative to omega-6s, with the omega-6 to omega-3 ratio often exceeding 15:1 (optimal is closer to 4:1 to 1:1). This imbalance contributes to chronic low-grade inflammation linked to cardiovascular disease, depression, cognitive decline, and autoimmune conditions. Increasing EPA and DHA intake through fatty fish (salmon, mackerel, sardines, anchovies) or high-quality supplements is one of the most evidence-supported nutritional interventions. Dosing recommendations vary significantly by health condition and life stage. General health maintenance requires far lower doses than cardiovascular disease management or triglyceride reduction. This calculator provides a starting point based on professional guidelines — specific medical conditions may warrant different doses or prescription-grade formulations under medical supervision.
How Fish Oil Recommendations are Determined
Recommendations are based on guidelines from the American Heart Association (AHA), European Food Safety Authority (EFSA), WHO, and published clinical research for each health profile. General healthy adults: 250–500 mg EPA+DHA/day (AHA minimum). Pregnant/breastfeeding: 200–300 mg DHA/day minimum (EFSA). Cardiovascular disease: 1,000 mg EPA+DHA/day (AHA). High triglycerides: 2,000–4,000 mg EPA+DHA/day (prescription level, medical supervision required). Standard fish oil capsules (1g total) typically contain 180 mg EPA and 120 mg DHA (300 mg EPA+DHA combined). Concentrated formulations may provide 500–600 mg EPA+DHA per capsule. Always check the actual EPA+DHA content on the supplement label, not just the total 'fish oil' amount.
Frequently Asked Questions
Fish oil is a source of omega-3 fatty acids (EPA and DHA), but not all omega-3 products are fish oil. Algae-based omega-3 supplements provide DHA (and sometimes EPA) directly from the original algae source that fish eat — making them a vegan alternative with equivalent DHA content. Krill oil provides EPA and DHA in phospholipid form, which may have slightly higher bioavailability. Flaxseed and other plant sources provide ALA, which the body converts to EPA/DHA very inefficiently (< 5%).
Fish oil is best absorbed when taken with a meal containing fat, which stimulates bile secretion and enhances omega-3 absorption. Taking fish oil with food also reduces the 'fishy burp' side effect common with some products. Enteric-coated capsules, frozen capsules, or high-quality refined fish oil products typically minimize this issue regardless of meal timing.
Yes — for general health maintenance, eating fatty fish (salmon, sardines, mackerel, herring, anchovies) 2–3 times per week provides adequate EPA+DHA for most healthy adults. A 100g serving of salmon contains approximately 2,000–3,000 mg EPA+DHA. Supplements become particularly valuable for those who do not eat fish regularly, have elevated triglycerides, are pregnant, or have other conditions requiring higher doses.
