Research & Citation Standards

• Systematic reviews, clinical guidelines, and high-quality controlled studies when appropriate.
• Primary publications instead of derivative summaries whenever available.
• Government and recognized professional sources for regulatory and public-health facts.
• Manufacturer materials only for clearly attributed product specifications or claims.

We distinguish established, moderate, emerging, and limited evidence. The label describes the available literature, not certainty for an individual patient.

References should identify the title, organization or authors, year, journal when available, and a stable source link, DOI, or PMID. Readers should consult the original publication before clinical or academic use.

Summaries should state relevant uncertainty, study limitations, and conflicts where known. Absence of evidence is not presented as evidence of no effect.
