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.

Evidence Summary
Evidence lens
Read as directional context, not settled clinical proof.
LimitedLimited Evidence
Human clinical evidence: Not the primary signal
Mechanistic / preclinical: Mechanism mapped — Neuroprotective Activity
Research maturity: Theoretical / mechanistic research — Mechanistic or unresolved evidence is kept separate from established human outcomes.
Safety boundary: Safety note available — May lower blood pressure or increase heart rate in sensitive users.
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
Dosing & Timing
- No standardized dose
- Preparation specific; use standardized product label for Evidence is strongest for standardized forskolin extracts and require source backed dosage review before therapeutic claims.
