Evidence Summary
Profile-wide ·D PreliminaryEvidence lens
Early signal that needs stronger human replication before practical claims.
PreliminaryPreliminary evidence
Human clinical evidence: Not the primary signal
Mechanistic / preclinical: Mechanism mapped — Metabolic Regulation · HDL Increase · Vascular Function Support
Research maturity: Theoretical / mechanistic research — Mechanistic or unresolved evidence is kept separate from established human outcomes.
Safety boundary: Safety note available — Flushing; hepatotoxicity at high doses.

How evidence grades work
Each grade reflects the strength and consistency of published human evidence — not marketing claims. Grades are based on study count, design quality, effect size, consistency, and recency.
- Strong
- Multiple RCTs, consistent direction, adequate effect size
- Moderate
- Some RCTs or consistent observational data in humans
- Preliminary / Mixed
- Animal or in-vitro only, or conflicting human data
- Traditional / Theoretical
- Traditional use only; no controlled human trials
How Niacin Works
Simplified mechanism pathway based on preclinical and pharmacological evidence. Does not confirm clinical efficacy.
