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
