01 / MATCH THE FORMULA
The details to pin down.
Ingredient identity & form
Identify ubiquinone or ubiquinol, carrier system, and any combination ingredients.
Dose, duration & study fit
Form, milligrams, duration, baseline characteristics, and background medications in the study.
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?
Separate healthy-adult outcomes from disease-management studies. Match the fatigue scale or exercise test to the proposed wording.
- 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?
