Evidence Rules
Research and Citation Policy
Citations should help a reader verify a specific statement, not create the appearance of authority through a long reference list.
Our evidence hierarchy
We use the strongest relevant source available for the claim being made.
- Government health agencies, regulations, and professional clinical guidelines
- Systematic reviews and meta-analyses of relevant human evidence
- Randomized controlled human trials
- Observational human research when stronger evidence is unavailable
- Mechanistic, animal, or laboratory evidence only with explicit limitations
How citations are used
A source must support the nearby claim in population, intervention, outcome, and degree of certainty. Evidence about magnesium generally is not presented as proof about magnesium glycinate specifically.
What we avoid
- Treating a small or preliminary study as settled science
- Using a source that discusses a different magnesium form as direct proof
- Presenting association as causation
- Hiding null findings, adverse effects, or important study limitations
- Citing another retailer as the authority for a medical or scientific claim
Sources and Evidence sections
Every retained health article includes a Sources and Evidence section. Each entry identifies why the source is relevant, while the article itself states the limitations that affect its conclusion.
