Safety & Cautions
Elevated caution
Caution level: Elevated. One caution category applies — read it before use.
- Pregnancy/Breastfeeding CautionPregnancy or breastfeeding caution language is present.
- Safety evidence
- extended release may prolong exposure and next-day drowsiness, but formulation-specific comparative safety evidence is limited
- Who should avoid this?
- No specific evidence-backed contraindication is documented for this profile. This is not the same as established safety.
- Talk to a professional if
- you are pregnant or breastfeeding.
Headache and dizziness occur in melatonin trials; driving, concurrent sedatives, pregnancy, breastfeeding, pediatric use, and chronic use require individualized review.
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 — MT1/MT2 Receptor Mediated Circadian Regulation · Circadian Phase Timing Support · Hormonal Signaling Context
Research maturity: Theoretical / mechanistic research — Mechanistic or unresolved evidence is kept separate from established human outcomes.
Safety boundary: Safety note available — Safety evidence: extended release may prolong exposure and next day drowsiness, but formulation specific comparative safety evidence is limited.

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
