Lab-Tested Kratom in Canada: How to Read a Certificate of Analysis
“Lab-tested” only means something if you can see the report. A Certificate of Analysis (COA) is an independent lab document showing what’s actually in a kratom batch — and what isn’t. Therefore, this guide shows what a real COA contains, line by line. It also lists the red flags that mean you should buy elsewhere.
Also, you can browse the shop, check where we deliver or contact our team with questions.
Why Lab Reports Matter in Canada
Kratom is an unapproved natural health product in Canada, which means no government agency checks its quality before sale. As a result, the COA is the only verification you get. Untested batches, for example, can carry heavy metals from contaminated soil, mould from poor drying, or bacteria like Salmonella. All of them are invisible to the eye. In fact, Health Canada has seized untested retail kratom for exactly these reasons.
The Four Sections of a Real COA
Red Flags That End the Conversation
- No COA available — after all, “we test everything” without paperwork means nothing;
- Company-wide COA instead of batch-specific — one old report doesn’t cover today’s stock;
- Health claims — “treats pain,” “cures anxiety” violates Health Canada rules (see the legal guide);
- Suspiciously cheap kilos — testing costs money; therefore, prices far below the fair-price band usually skip it;
- Vague sourcing — instead, quality vendors name the region and harvest practices.
How to Ask for a COA (and What a Good Vendor Says)
Email or message the vendor: “Can you send the COA for the current batch of ?” A quality vendor then replies with a PDF. It shows a recent date and the batch number that matches your bag. However, anything else — delays, excuses, generic marketing pages — is your answer.
Testing and Capsules
Encapsulated products need two tests: the powder before filling, and the finished capsules for fill-weight consistency. Details in our capsules guide.
What our lab tests check
Every batch we sell goes to an outside lab first. The lab checks five things:
- Heavy metals, such as lead.
- Bacteria.
- Mould.
- Pesticides left on the leaf.
- Alkaloid content, which shows how much mitragynine the batch has.
Each batch gets its own lab certificate. You can ask us for the certificate for the product you want.
Lab-tested kratom strains we sell
Every strain in our shop is lab-tested, batch by batch. Here is the full range by vein colour:
- Red vein: Red Maeng Da, Red Bali, Red Borneo
- Green vein: Green Maeng Da, Green Malay
- White vein: White Maeng Da, White Hulu
- Yellow and gold: Yellow Thai, Gold Maeng Da
We also sell kratom capsules and our Strong Kratom Powder Mixture, made from the same tested powder.
Frequently Asked Questions
What does "mitragynine percentage" mean?
Mitragynine is kratom’s primary natural alkaloid. The COA states how much of it the batch contains. This figure therefore confirms the leaf is genuine and fresh.
How do I know the lab itself is legitimate?
First, look for ISO 17025 accreditation on the report. Then verify the lab exists independently of the vendor.
Does a COA guarantee results?
No — instead, it guarantees transparency and safety screening. After all, that’s exactly what an unregulated product category needs.
Is all your kratom lab-tested?
Yes. Every batch of every product is tested by an outside lab before we sell it.
Can I see the lab certificate before I buy?
Yes. Every batch has its own lab certificate. Text (647) 330-9497 or email us to ask for the one for the product you want.
