Kratom (Mitragyna speciosa) is a tropical tree from the coffee family (Rubiaceae), native to Southeast Asia. At Next Level Smart our kratom comes directly from our own plantation in West Kalimantan, Indonesia — no middlemen, only pure Mitragyna speciosa of consistent quality.
Kratom leaves are traditionally categorised by vein colour, reflecting the drying process and alkaloid profile:
Alongside loose colours we offer kratom extracts and whole kratom leaves. All products are tested for purity and contain no pesticides or artificial additives.
Our plantation in West Kalimantan manages the full process — from plant to packaging. For the Indonesian kratom tradition and botanical background, read our Kratom Blogs.

Kratom, scientifically referred to as Mitragyna speciosa, is a tropical tree indigenous to Southeast Asia, the Philippines, and New Guinea, now cultivated across various regions.
Belonging to the Rubiaceae family, this tree can reach heights of 4 to 16 meters. It is notable for containing over 40 structurally related alkaloids, with mitragynine and 7-hydroxymitragynine being the most prominent.
Kratom leaves, which are oval or ovate-lanceolate and dark green in color, can be processed into crushed or powdered forms for various uses. Traditionally utilized in Southeast Asia, Kratom has gained global popularity for its diverse properties. Discover our range of Kratom products: Extracts, Leaves, and Powder, and for an in-depth look at how Kratom powder is produced, explore our blog post on the production process.
Our Kratom selection encompasses various forms, from traditional leaves esteemed for their natural state to finely ground powder for easy water mixing, and potent extracts for concentrated solutions. Each product form highlights a different facet of Kratom's botanical essence.

Kratom Types categorize the diverse strains of the Kratom plant, each distinguished by unique characteristics derived from their region of growth, leaf maturity, and processing methods. These types include Green, White, Red, and Yellow Kratom, each offering a distinct profile.
The classification into different types helps navigate the varieties of Kratom, based on the plant's cultivation and preparation, reflecting the rich cultural and botanical heritage of this unique plant.
Each type's distinct coloration reflects the maturity and processing method of the leaves, contributing to their classification.
At Next Level, we stand as one of Europe's premier Kratom suppliers, dedicated to bringing only the finest natural products to your doorstep.
We guarantee the highest quality Kratom by overseeing every production stage, from cultivation in Indonesia to processing in our facility. Quality is assured with each batch tested in our laboratory. Working directly with our farmers eliminates middlemen, ensuring cost-effectiveness.
Please note that, Given that Kratom does not appear on the list of approved novel foods and ingredients (Regulation (EC) No. 258/97), we do not market Kratom for human consumption. Please be aware of these restrictions when purchasing.

The choice depends on the alkaloid profile you are looking for. Green kratom from Jongkong has the most balanced profile. Red kratom from Sentarum is fermented longer with more 7-hydroxymitragynine. White kratom from Putussibau contains more unoxidised mitragynine. Yellow kratom combines green and red characteristics via a hybrid drying process.
The colour (green, red, white, yellow) is determined by the drying method and fermentation level, not the leaf colour. Green kratom is shade-dried to preserve chlorophyll. Red kratom undergoes longer fermentation and sun drying. White kratom is harvested young and dried without fermentation. Each process yields a unique alkaloid profile. Read our Complete Kratom Guide for a detailed comparison.
Store kratom in a cool, dry and dark place in an airtight container, away from direct sunlight. UV light and moisture break down the alkaloids, causing quality to deteriorate quickly. Properly sealed in the original packaging, kratom stays fresh for up to 3 months. Vacuum sealing significantly extends shelf life.
We offer kratom as loose leaf, finely ground powder and concentrated extract. Loose leaf is the most traditional and unprocessed form with the longest-preserved alkaloid profile. Powder is versatile and can be precisely weighed with a precision scale. Extracts contain a higher concentration of mitragynine per gram through a controlled extraction process.
Yes, kratom (Mitragyna speciosa) is fully legal in the Netherlands and is not listed under the Opium Act. It is freely traded as a botanical product. However, regulations differ per country — some EU countries have introduced restrictions. Always check local legislation if you live outside the Netherlands.
