Context before conclusions
Every summary should preserve what was studied, who was studied, the ingredient form and amount, duration, outcome, uncertainty and source date.
Start with the strongest appropriate source
We prioritize systematic reviews and meta-analyses, then controlled human studies, observational human evidence and clearly labeled mechanistic, animal or in-vitro research. An authoritative public-agency summary may anchor consumer context without replacing the underlying evidence.
Separate ingredient and product evidence
A study of an ingredient does not prove that a commercial formula works. Exact-product trials, label declarations, manufacturer claims and NutraFavorites analysis remain visibly distinct.
Record limitations
Population, comparator, duration, outcome, form, amount, conflicts, inconsistency and indirectness can all limit what a source supports. Absence of evidence is recorded as uncertainty, not proof of no effect.
Maintain freshness
Evidence summaries show retrieval and review dates. Material new evidence triggers review; stale or incomplete records remain visibly labeled until updated.
Evidence labels are context-specific
A label such as established, contextual or limited applies to a defined outcome and context—not to an ingredient in every use. We avoid turning studied ranges into personalized dosing instructions.
Claims remain classified
Label facts, nutrient-content claims, structure/function claims, disease-related claims and editorial conclusions are stored as different statement types so marketing language is never presented as independent evidence.
