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.

A

Strong

Multiple RCTs, consistent direction, adequate effect size

B

Moderate

Some RCTs or consistent observational data in humans

C

Preliminary / Mixed

Animal or in-vitro only, or conflicting human data

D

Traditional / Theoretical

Traditional use only; no controlled human trials

Compound profile context

How to interpret Icariin

Icariin dosage by use case, onset and duration, safety limits, and interactions for pde5 no, graded against research. Limited Human Evidence research evidence. 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 Icariin, 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.
