▶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

Product Form & Quality Guidelines
When sourcing Probiotics, verify the label for:
- Standardized Extract: Confirm active content percentages on the supplement facts panel (e.g. standardized to specific marker compounds) rather than simple raw herb weights.
- Third-Party Testing: Look for independent purity labels (USP, NSF, ConsumerLab, or Eurofins) to ensure the product is free from heavy metals, solvents, and contaminants.
- Form Bioavailability: Ensure the form matches evidence-supported configurations (e.g. chelated bisglycinate/glycinate for magnesium, micronized monohydrate for creatine) for optimal onset and digestion tolerance.

Editorial Review
Reviewed against source evidence and safety constraints
Profiles are checked against primary sources, cited evidence, and contraindication language before publication. This is editorial review, not personal medical advice or a named clinician endorsement.
Evidence claims are matched to human, mechanistic, or traditional-use context.
Safety language is kept conservative when interaction or population data is incomplete.
Affiliate modules are separated from evidence ratings and caution language.
Editorial Process: We synthesize preclinical pharmacology, human clinical data, and source registry context while preserving uncertainty and avoiding commercial hype.
