Overview
- The study synthesized 42 technical and scientific documents underpinning national and international guidance across life stages and regions.
- Recommendations vary widely by country and format, with intakes expressed as mg/day, percent of fatty acids, or mg/kg, creating public confusion.
- The most common advice is 250 mg/day of combined EPA+DHA for adults and an extra 100–200 mg/day of DHA during pregnancy, with higher intakes for low-status pregnancies in some guidance.
- Authors report many people cannot meet targets from diet alone because of low seafood intake, sustainability concerns, and limited access to advice, so supplementation and alternative sustainable sources may be needed.
- Published in Nutrition Research Reviews by researchers from the University of East Anglia, the University of Southampton, and collaborators, the paper aims to inform policy and harmonize guidance globally, including regions developing public advice.
