Although omega-3s are considered vital, there is no established Adequate Intake (AI) or Dietary Reference Intake (DRI) in the United States for EPA and DHA omega-3s. Governments in other countries and a variety of expert scientific bodies around the world have set recommendations between 250 and 1000 mg of EPA and DHA per day. GOED recommends at least 500 mg EPA+DHA per day for overall health — more if you’re pregnant, breastfeeding, or have a history of heart disease.
