What The Labs Test For

Every batch of KO Kratom undergoes rigorous testing by an accredited third-party laboratory. Here is a breakdown of what we test for to ensure your safety and satisfaction.

Kratom Alkaloids

We test for the two primary active alkaloids in the Kratom leaf to ensure potency and consistency across all our products.

Mitragynine1.5% Floor
7-Hydroxymitragynine<0.05%

Heavy Metals

Because Kratom is grown in soil, it can absorb heavy metals. We test to ensure levels are well below the strict safety limits.

Lead (Pb)
Arsenic (As)
Cadmium (Cd)
Mercury (Hg)

Microbials & Pathogens

We screen for harmful bacteria and biological contaminants to guarantee the cleanliness of our Kratom powder.
