Fish Oil Supplementation Guidelines

Introduction to Fish Oil Supplementation

• The largest population study on fish oil supplementation, the VITAL trial, with 25,871 participants, used a dosage of 860 mg of EPA+DHA daily for cardiovascular benefits, showing significant reductions in myocardial infarction risk, particularly in Black individuals 1
• The International Society for the Study of Fatty Acids and Lipids recommends 500 mg of EPA+DHA daily for healthy humans 2

Primary Prevention

• For primary prevention in healthy individuals, at least 500 mg/day of combined EPA+DHA is recommended by the International Society for the Study of Fatty Acids and Lipids 2

Secondary Prevention

• For secondary prevention in individuals with existing coronary artery disease, 850-900 mg/day of omega-3 fatty acids (as EPA+DHA) has shown to reduce overall mortality by 20% and sudden death by 45% 3
• Consuming 1 fatty fish meal per day (or a fish oil supplement) could provide approximately 900 mg/day of EPA+DHA for cardiovascular benefits 3

Hypertriglyceridemia Treatment

Cancer Patients

• Fish oil (most frequently used doses: 4-6 g/day) and long-chain N-3 fatty acids (1-2 g/day) are used in cancer patients 4
• At least 2 g/day of N-3 fatty acids are required for clinical benefit on nutrition-related endpoints in cancer patients 4

Intensive Care Unit Patients

• Parenteral lipid emulsions enriched with EPA+DHA at 0.1-0.2 g/kg/day are used in intensive care unit patients 2

Safety and Efficacy

• Long-term supplemental intakes of EPA and DHA combined up to about 5 g/day do not appear to increase the risk of spontaneous bleeding episodes 4
• Supplemental intakes of EPA alone up to 1.8 g/day are considered safe for adults 4
• Mild gastrointestinal effects, fishy aftertaste, or fish belching may impair compliance 4
• Patients receiving ibrutinib (for chronic lymphocytic lymphoma) should avoid fish oil supplements due to risk of epistaxis 4
