Research and citations
Our source-based editorial approach uses published studies, systematic reviews and authoritative reference material. Prioritize relevant human research and consider study design, population, formulation, dose, outcomes and limitations. Systematic reviews provide context, but their conclusions depend on the quality and relevance of the included studies. Articles identify supporting sources and preparation dates; a preparation date is not a study publication date.
Interpreting the evidence
Our role is editorial interpretation of published information, not independent scientific review. An ingredient finding does not establish that a retail product produces the same result. Manufacturer information describes a product; it is not independent evidence of clinical effectiveness.
Product selection
Product selection starts with the reader’s task. We consider exact ingredient form, flavor or variant, labeled serving, package and practical format. A product must fit the specific article; shared keywords alone are insufficient. Some articles have no shopping recommendation.
Comparisons
Our comparisons describe meaningful differences rather than declaring a universal winner. We do not infer superior effectiveness from a higher dose, price, strain count or absorption claim, and we do not invent ratings, personal testing or current prices.
Editorial independence and disclosures
Select products for their fit with the reader’s task and the available evidence, rather than commission size. Affiliate income supports the site, but a commission is not evidence that a product is suitable or superior. Disclose material ownership, employment, sponsorship or gifted-product relationships with the relevant content.
Product identity and retail links
Retail links require an identified product and approved destination. Product data and images can change; uncertain identities or expired images stay unavailable until checked. We distinguish a page draft from a product cleared for a purchasing link.
Updates and corrections
Revisit affected content when new evidence, a changed formulation, a broken source or a reader correction changes the discussion. Check material claims against the cited source, preserve important qualifications, and record the reason for material corrections. Update related product dossiers, comparisons and article placements together where needed.
