Kratom products are tested by independent laboratories to verify alkaloid content and screen for potential contaminants. Because kratom is a natural botanical, alkaloid levels can vary between batches, making testing an important part of product evaluation.
Analysis typically includes key alkaloids such as:
- Mitragynine
- 7-Hydroxymitragynine
- Speciogynine
- Speciociliatine
- Mitraphylline
- Corynoxine
Additional screening may include heavy metals and microbial contaminants depending on the product.
Certificates of Analysis (COAs) allow you to review batch-specific results rather than relying on general product claims.

Why Third-Party Testing Matters for Kratom
Kratom is a raw botanical, which means quality can vary depending on sourcing, handling, and processing. Third-party lab testing helps confirm that products are screened for contaminants and meet basic safety and consistency standards.
Testing is typically used to check for:
- microbial contamination such as bacteria, yeast, and mold
- pathogens including E. coli and Salmonella
- heavy metals like lead, mercury, cadmium, and arsenic
- alkaloid content (such as mitragynine levels)
Because kratom is not federally standardized, independent testing plays a key role in verifying what’s actually in a product.
How to Read a Kratom Certificate of Analysis (COA)
A Certificate of Analysis (COA) is a third-party lab report that provides a breakdown of a kratom product’s composition and screening results.
Key sections typically include:
Alkaloid Profile
Measures active compounds like mitragynine to give a general sense of composition and consistency between batches.
Heavy Metal Screening
Checks for elements such as lead, mercury, cadmium, and arsenic that can occur in plant-based materials.
Microbial Testing
Screens for bacteria, yeast, mold, and harmful pathogens.
Contaminant Screening
May include additional checks depending on the lab and product type.
Reviewing a COA allows you to confirm that a specific batch has been tested, rather than relying on general claims about quality.
