Should Functional-Food Studies Use a Placebo-Controlled Design?
Functional-food clinical research should align product characterization, safety, ethics, study design, participants, endpoints, statistics, data quality, and reporting with the intended evidence and applicable regulations.
A placebo-controlled design can reduce bias when feasible and ethical, but the appropriate comparator depends on the research question, product, endpoints, participant population, and practical constraints.
Functional-Food Research
Functional-food research should use a well-characterized product, scientifically justified objectives, appropriate safety information, ethics review, suitable participants and endpoints, informed consent, quality controls, statistical planning, and transparent reporting.
