Disclaimer
This COA reports analytical results for this specific batch and does not constitute medical advice.
American Grit products are not intended to diagnose, treat, cure, or prevent any disease.
Results may vary by batch and source because fulvic chemistry is naturally variable.

Research Spotlight — Nature Portfolio (Scientific Reports)
We publish batch testing (COAs) because variability is leverage—and fulvic chemistry can differ by source, processing, pH, and mineral co-factors. Below is a peer-reviewed research reference that helps explain why documentation matters in this category.
American Grit and OperationAmericanGrit.com include this as educational context, alongside batch-specific COA results.
Publication
- Title: Integrated safety and microbiota profiling of fulvic acid formulations across in vitro and in vivo models
- Journal: Scientific Reports (Nature Portfolio), 2026

What the Study Did (Plain English)
The authors evaluated multiple fulvic-acid-containing preparations using cell-based assays (to look at cytocompatibility and genotoxicity) and microbiome-related assays (in vitro and an in vivo model) to examine selective effects on microbes.
The paper explicitly treats fulvic preparations as variable formulations—not a single uniform ingredient.
Important: This publication is presented as peer-reviewed context and does not replace batch testing.
It evaluates specific fulvic formulations in defined models and conditions; it is not a claim that every fulvic product
behaves identically, nor that this study alone establishes medical outcomes.
