01 / MATCH THE FORMULA
The details to pin down.
Ingredient identity & form
Record EPA and DHA separately, source oil, and chemical form; total fish-oil weight is not the EPA/DHA dose.
Dose, duration & study fit
EPA/DHA amounts, formulation, duration, background diet, and baseline health status.
Record the tested dose from the original study. A study dose is not a recommended dose or proof that every claim at that dose is supported.
02 / READ IN CONTEXT
What changes the interpretation?
Distinguish dietary intake studies, supplement trials, and prescription-product studies. Check baseline intake and the exact outcome measured.
- Population: Does the study population match your intended audience?
- Comparison: What changed compared with the control group—not just compared with baseline?
- Consistency: Do independent studies agree? Include null findings, limitations, and adverse events.
- Claim wording: Does the measured outcome support the strength and scope of the proposed claim?
