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 Iron, 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.

Compound profile context

How to interpret Iron

Iron dosage by use case, onset and duration, safety limits, and interactions for hemoglobin, graded against research. Strong 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 Iron, 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.
