Editorial method

How GutGuard reviews ingredient evidence

In short

GutGuard pages are written and evidence-checked by the GutGuard editorial team. We cite claims beside the text, separate evidence by study type and state what a label or study cannot tell you. We do not imply clinical review when none occurred.

GutGuard’s editorial method for sources, evidence separation, uncertainty, corrections and scope.

Who writes these pages

GutGuard editorial team

GutGuard’s guides are written and maintained by the GutGuard editorial team. We do not claim that a clinician reviewed a page unless a named clinician has actually done so.

How we work

Our evidence method

  • Start with the exact question a person has while reading a packet.
  • Prefer official UK guidance, systematic reviews and primary human studies.
  • State study size, dose, duration and design when those details change the meaning.
  • Keep human, animal, laboratory and observational findings visibly separate.
  • Put regulatory conclusions beside emerging research, including uncertainty in both.
  • Explain what a label or study cannot establish, not only what it found.
  • Correct factual errors and update dates when the substance of a page changes.

Scope

What GutGuard does not do

These pages do not diagnose conditions, identify the cause of symptoms, calculate an undisclosed ingredient dose, manage allergies or replace personalised medical or dietetic advice.

Corrections

Tell us when something needs attention

If a source has changed or a statement needs correction, contact us through GutGuard support. We check substantive corrections against the cited source and update the page date when its meaning changes.
