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 to interpret Tanshinone IIA
Tanshinone IIA compound profile with evidence context, key research topics, source notes, safety context, and references presented in an evidence-first… Use this compound profile to understand mechanism, evidence quality, and practical safety context before comparing products or building a stack. A biochemical pathway connection can be useful for discovery, but it is not the same as proven benefit in humans.
When reviewing Tanshinone IIA, separate the active molecule from the product category around it. Dose form, absorption, extract standardization, medication interactions, and individual sensitivity can change the real-world risk-benefit picture.
For supplement planning, avoid combining multiple compounds with overlapping sedating, stimulating, serotonergic, blood-pressure, anticoagulant, or liver-metabolism effects unless a qualified clinician has reviewed the context.
