Safety & Cautions
GI upset and fishy odor possible; caution seizure disorders and trimethylamine N oxide risk discussions in cardiovascular risk users.
High caution
Caution level: High. Multiple caution categories apply, or the record uses avoid/contraindication language.
- Interaction-AwareMedication or interaction context is explicitly noted.
- Hormonal Activity ContextHormone-adjacent wording is present and should be interpreted carefully.
Evidence-based safety
Caution when combined
Severity and certainty are shown separately. A high-priority caution can still be theoretical: these pairings are screened from shared contraindication mechanisms and are not automatically documented clinical interactions. Provenance identifies the source fields that produced each flag; it does not upgrade the certainty of the pairwise claim.

Evaluation of methodological rigor, population reach, and evidence alignment.
- Design Match
- Randomized controlled trial
- Risk of Bias
- Low
- Consistency
- Not assessed
Strongest recorded design is a randomized controlled trial, drawn from 2 recorded studies, 2 in people.
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
