People who have elevated triglycerides may need two to four grams of EPA and DHA per day provided as capsules under a physician’s care. |

European Society of Cardiology (ESC) | Eat fish twice a week, of which once oily fish2. The recommended doses of total EPA and DHA to lower triglycerides have varied between 2 and 4 g/day. Use of n-3 fatty acids (prescription products) as an adjunct to the diet if triglycerides exceed 5.6 mmol/L (496 mg/dL)3. | Eat fish twice a week, of which once oily fish2.

American College of Cardiology (ACC) | No recommendation. | Encourages increased consumption of omega-3 fatty acids in the form of fish or in capsule form (1 g/d) for risk reduction. For treatment of elevated triglycerides, higher doses are usually necessary for risk reduction4. |

World Health Organization (WHO)7 | Regular fish consumption (1-2 servings per week) is protective against coronary heart disease and ischaemic stroke and is recommended.
