Sourcing, processing, testing of Kratom

At Kraatje all kratom comes from a good, ethical and environmentally friendly source and is thoroughly tested before it reaches you. Every batch is lab-tested sterilized. We manage the entire supply chain ourselves, from sourcing in Indonesia to packaging in the Netherlands. Below we explain exactly how our kratom is sourced, processed and tested.

How our kratom is sourced and processed

Our kratom comes from experienced farmers in Indonesia, from regions where the kratom tree (Mitragyna speciosa) naturally grows. These farmers use sustainable and environmentally friendly farming practices, healthy rich soils and natural resources to grow their acres. All our kratom is sourced from soils with close to zero heavy metals in the ground; mercury, arsenic, cadmium, lead and mercury are practically non-existent. Because of this we ensure that all our kratom is free from toxic dosages of heavy metals. Other metals occur naturally in the leaves, however, absorbed by the tree from the soil. These are beneficial to its health, in supporting photosynthesis, respiration, and nitrogen assimilation.

We work with farmers across South-East Asia, they grow and nurture the trees, collect the leaves, and dry them in their own greenhouses until they are ready to be processed. After the leaves are properly dried, the stems and veins are separated from the leaf material. Then, our partner Borneo World Kratom, a leading producer of kratom in Indonesia, ships the dried leaves to their factory, where they are further dried and fermented until they reach the right moisture level for making kratom powder. 

Grinding, testing and homogenizing

Next the dried leaves are ground into a fine powder. But just grinding is not enough to guarantee a consistent product. That is why every batch goes through a homogenizing process with an industrial mixer. This makes sure that the alkaloid profile, including the mitragynine percentage (MIT%), is evenly distributed across the entire batch. Whether you open the first bag or the last, you get the same quality.

Every batch is tested twice during production. The first test happens after grinding, and a second test after homogenizing. The batch gets separated into multiple sub-batches to ensure consistency. This confirms that the entire batch is potent and of quality throughout .

Sterilization

All our kratom batches are sterilized by food-grade gamma radiation. This is the same technique used in the food and pharmaceutical industry to kill bacteria, molds and other micro-organisms, insects and pests. It is a non-chemical method that does not alter the alkaloid profile. After sterilization the kratom is clean and free from micro-organisms.

How we test our kratom

What do we test for?

Our lab testing covers three important areas:

Microbiological testing: Every batch is tested for bacteria and micro-organisms. This includes total aerobic plate count, coliforms, E. coli, Salmonella, Staphylococcus aureus, and yeast and mould levels. Only batches that pass these tests make it to our shelves.

Alkaloid profile: The alkaloid content of each batch is tested to verify the concentration of key alkaloids, in particular mitragynine, which is considered the most important alkaloïde in determining quality. This way we know every batch has the expected alkaloid profile for its strain. You get consistent quality, every time. You can view our lab-tests here

Why we take testing so seriously

Kratom is a natural product and natural products can vary. Different harvests, different weather, different soil, different trees, it all has an effect on the final product. Lab testing and homogenization is how we control that variability and deliver consistent quality.

We source directly from certified Indonesian farms, process under strict conditions, test every batch and sterilize before packaging. It is a process we have refined over more than 12 years. This is also why over 7,250 customers have rated us 9.6/10 at ValuedShops. Our kratom reviews speak for themselves.
