Sourcing Policy

Material health, product and regulatory statements should be traceable to the strongest accessible source that directly answers the claim.

Source order

1. Regulators, public-health agencies, official labels and authoritative databases
2. Clinical guidelines and major professional societies
3. Peer-reviewed trials, systematic reviews and transparent observational research
4. First-party product pages for current specifications, price and terms
5. Independent certification databases for the exact listed product

What first-party sources can support

A product page can document its current label, size, price or company claim. It cannot independently prove comparative benefit, batch quality, clinical effectiveness or user experience.

What we do not infer

Paywalled details, unreported subgroups, unseen supplements, future regulatory status, product testing, identity or sterility are not reconstructed from snippets or marketing language.

Freshness

Regulatory, product, price, certification, affiliate-term and safety claims receive dated checks and event-driven updates when a label, recall, warning, guideline or material source changes.
