Kratom Quality Under the Microscope: Our Lab Tests & Analysis

1. Why are laboratory tests necessary for Kratom?

Kratom powder can, in rare cases, be contaminated with heavy metals, pesticide residues, or unwanted microbes. To ensure that you receive only a clean, safe product, every reputable supplier subjects their stock to comprehensive testing before sale. At Kratom.eu, we make no compromises.

By analyzing the alkaloid profile, we also ensure that each batch contains the expected levels of mitragynine and other key alkaloids, keeping its composition consistently uniform.

2. Where is our Kratom tested?

In tests of identical, homogenized samples, various laboratories showed significant deviations in mitragynine values. Many competitors rely on fast, low-cost lab services whose analyses are often imprecise and tend to report the highest possible alkaloid levels. Our supplier Bigtrea, by contrast, searched meticulously for the laboratory that provides not the highest, but the most accurate results.

After extensive comparative trials, the choice fell on the Murray Brown Laboratory in the USA. Thanks to its outstanding expertise in alkaloid analysis, it delivers consistently precise and reliable results. Every batch of Kratom powder that reaches us is tested by Bigtrea there—for total assurance and genuine quality.

3. Why are only the test results for Bigtrea Premium Kratom published?

As a pure natural product, a single sample of Kratom can only ever provide an indication for the entire batch. A pallet of about 500 kg of Kratom, spread across around 20–25 boxes, inevitably exhibits variations: even within one box, mitragynine content can vary, since each leaf contains different concentrations. Upon receipt, a sample is taken from one box and tested—but it is not representative of the whole batch.

Only through thorough homogenization—mixing the entire batch over several hours, as is done for our Bigtrea Premium and Bigtrea Ultra Enhanced products—do we obtain a uniform sample that allows reliable conclusions.

For the sake of transparency and to avoid misunderstandings, we therefore publish only the analysis certificates of these homogenized Premium and Ultra-Enhanced batches. We do not release the test reports for our regular Kratom, as this could lead to incorrect assumptions about partial lots.

4. How is the hygiene of the Kratom powder ensured?

Before your Kratom powder arrives at our warehouse, it undergoes a microbial reduction process also used in the food industry. This step further lowers the microbial load and adds an extra layer of safety to the laboratory tests.
