Editorial policy

The sourcing, writing, review and update standards behind HowToSupplement.

Updated 7/12/2026

Evidence standards

We prioritize clinical guidelines, government fact sheets, systematic reviews, meta-analyses and controlled human trials. Observational, mechanistic, animal and traditional-use evidence is labelled accordingly.

  • Claims must match the studied outcome and population.
  • Safety and interaction limitations appear close to recommendations.
  • Popularity, sponsorship and affiliate value do not change evidence grades.
  • Material changes receive a new evidence-review date and change log.

Use of automation

Automation may assist with structured extraction, translation, consistency checks and drafting. It does not independently approve health claims, doses, safety classifications or review status.
