Evidence Summary

Profile-wide ·D Preliminary

Evidence lens

Early signal that needs stronger human replication before practical claims.

PreliminaryPreliminary evidence

Human clinical evidence: Not the primary signal

Mechanistic / preclinical: Mechanism mapped — Vascular Function Support · Caffeine Alike CNS Stimulation · Adenosine Receptor Antagonism

Research maturity: Theoretical / mechanistic research — Mechanistic or unresolved evidence is kept separate from established human outcomes.

Safety boundary: Safety note available — "Potential stimulant effects; caution cardiovascular disease

Evidence Strength

Confidence estimate based on the design quality and consistency of published clinical trials.

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
