Our evidence hierarchy
- Current product label: ingredients, amounts, warnings and serving directions.
- Official merchant or brand page: pricing, guarantee language, product positioning and current instructions.
- Government and primary research context: used for clinical evidence and safety interpretation.
- Secondary sources: used cautiously and not as a substitute for the current label when the label is available.
How we describe claims
Seller statements are identified as merchant claims. Ingredient research is not converted into a claim about the finished product unless the finished product itself has appropriate evidence. We do not invent testimonials, firsthand experience, medical outcomes, prices or doses.
Corrections and updates
Product pages can change. Major commercial facts on this site record the date checked. If a current shipped label conflicts with older web copy, the current label should control.
Comparisons
Comparison pages are intended to clarify differences in formulas, transparency and evidence context. They do not claim that one product is medically appropriate for every reader.
