Editorial standards
This site publishes education about a compound whose name is its marketing claim and whose evidence is old, small, and contradictory. That combination sets our standards.
Our review process
The core monograph, evidence table, and claim manifest are built from a claims ledger matched to primary sources and graded by study design. Regulatory statements distinguish FDA records from attributed trade-press reporting. No named physician or clinician has reviewed this site, and we do not claim medical review. The generated guide archive and interactive tools have not completed the standard required for high-risk medical publication; they are visibly labeled, set noindex, and excluded from sitemaps and AI citation files until individually reviewed and approved.
Sourcing rules
We cite primary sources: peer-reviewed literature via Europe PMC and PubMed Central, and government records from FDA, ClinicalTrials.gov, PubChem and the NLM. 41 of this site's 42 references (97.6 percent) are peer-reviewed or government sources; the one press citation exists solely to carry the attributed committee-vote report and is visibly badged as press. Every reference URL is checked for a 200 response at build time. We do not cite vendor pages, supplement blogs or press releases as evidence of efficacy or safety.
Update policy
Pages carry a visible last-updated date. The regulatory sections will change: FDA's July 2026 proposal is a recommendation-stage action and the rulemaking is pending, so the PCAC page will be rebuilt when FDA acts, and the change will be dated. Literature census figures are re-run against the same archived queries so that a changed number is always a changed literature and never a changed method.
Corrections and feedback
If you find an error, tell us and we will fix it and say what changed. Corrections are made on the page itself with the date, not silently. We are particularly interested in corrections from anyone with access to the older sleep-laboratory literature in full text: five of our cited papers are indexed without abstracts, and where we relied on FDA's 2026 review to describe them, the pages say so.
