Our Evidence Hierarchy
- Current physical product label
- Current seller-controlled product information
- Government and academic health sources
- Peer-reviewed human research
- Secondary sources used for discovery and cross-checking
- Testimonials and forum anecdotes, treated as low-level signals
Our Core Rule
Evidence about an ingredient is not automatically evidence about the finished product. We state that distinction throughout the site.
Our Evidence Hierarchy
The first layer is what can be directly verified from the product label or official product materials. The next layer is relevant research on the exact ingredient form and dose. Human clinical evidence generally carries more weight for outcome questions than mechanistic explanations or laboratory findings. Consumer anecdotes can identify questions but are not treated as controlled evidence.
Our Core Rule: Match the Claim to the Evidence
A label can tell us what is in a product. An ingredient study can tell us what happened in that study. Neither fact alone proves that the finished product produces a specific outcome for every buyer. Pages therefore try to identify whether a statement is a label fact, seller claim, research finding, interpretation, or unresolved question.
Safety Review
Safety discussions consider the ingredient list, known cautions where supported by reliable sources, and the limitations of available information. The site does not attempt to provide individualized medical clearance. Where medication interactions or health conditions may matter, readers are directed toward qualified professional advice rather than a blanket safety conclusion.
Commercial Information
Price, package size, shipping, guarantee, and purchase terms are treated as dynamic commercial information. We avoid implying that an old price is permanent and encourage readers to verify the current checkout before payment. Affiliate links are disclosed and are not treated as evidence of effectiveness.
Updating Pages
Pages may be reviewed when product materials, pricing, labels, research, or site policies change. The visible update date helps readers understand that a page is time-sensitive. If a claim can no longer be supported by the available source, it should be revised, qualified, or removed.
What We Avoid
We avoid invented testimonials, fabricated study findings, guaranteed health outcomes, keyword-stuffed claims, and presenting indirect ingredient evidence as if it were a direct product trial. We also avoid hiding commercial relationships or using a positive conclusion as a substitute for evidence.
Frequently Asked Questions
How does the site evaluate evidence?
It starts with directly verifiable product information, then considers relevant research and separates stronger evidence from indirect or anecdotal information.
Why separate ingredient and product evidence?
Because a study of an ingredient or different formulation does not automatically establish the effectiveness of the finished product.
Are testimonials treated as proof?
No. Anecdotes can raise questions but cannot establish efficacy or calculate how often a product works.
How are commercial claims handled?
They are treated as seller-facing information and should be verified against current pricing, checkout, shipping, and guarantee terms.
What happens when evidence is uncertain?
The uncertainty is stated rather than replaced with a stronger conclusion than the evidence supports.
