Lab testing verifies what a supplement contains and what it does not. Third-party testing means an independent laboratory runs the analysis, so the verification does not rest on the manufacturer's own checks.
Screening And Extracts
Pesticide residues can remain on botanical material, and residual solvents can remain from the extraction process. Screening confirms both sit below acceptable limits.
For extracts this matters more than for raw botanicals. Extraction concentrates whatever is in the plant material — the alkaloids and any contaminants alike.
Why Testing Is Not Universal
Supplement regulation does not require comprehensive contaminant screening for every product, and full panels cost money. Many products are sold on basic quality checks alone.
Reading A Certificate Of Analysis
- Match the lot or batch number to the product label.
- Confirm the product identity section matches the claimed material.
- Check the potency results — for kanna, the alkaloid levels — against the label.
- Review the contaminant screens: heavy metals, pesticides, residual solvents, and microbials, each against its limit.
- Note the methods used, such as HPLC (high-performance liquid chromatography).
- Check the lab's name, accreditation, and the date of analysis.
How We Test
Every Kanna Extract Co. lot is tested twice: in-house by HPLC, and by an independent third-party laboratory for its alkaloid profile plus screening for heavy metals, pesticides, residual solvents, and microbial contamination.
Where a certificate of analysis has been issued for a product, it is published on that product's page. Certificates for the current lot are available on request.
Common Questions
If a product has no published certificate, has it not been tested?
Those are two different things. A certificate is a document; testing is the work behind it. Every lot we sell is tested in-house and by an independent laboratory whether or not a certificate is posted on the page, and current-lot certificates are available on request. Ask any seller the same question and judge the answer.
What is HPLC?
High-performance liquid chromatography — the standard laboratory method for separating and quantifying compounds in a mixture. For kanna it is what produces the alkaloid figures: how much total alkaloid is present, and how the mesembrine, mesembrenone, and ∆7-mesembrenone shares divide up. Those numbers are what a label can then state — see How To Choose A Kanna Extract.
How do I know a certificate is genuine?
Check that the laboratory is named and accredited, that the date of analysis is recent, and that the lot number on the certificate matches the lot number on the product in your hand. A certificate with no lot number, no lab name, or no date is not evidence of anything. Where a laboratory is named, you can contact it directly.
Does a clean certificate mean the product suits me?
No. A certificate speaks to identity, potency, and contaminants. It says nothing about whether a substance is appropriate for you. Kanna is serotonergic and rules out a specific list of medications and supplements — that list is in Kanna Side Effects & Safety.
Kanna is serotonergic. Consult a healthcare provider before use, especially if you take any serotonergic medication or supplement.
