White kratom is harvested early in the Putussibau region, the capital of the Kapuas Hulu district at the upper reaches of the Kapuas River in West Kalimantan. The young, light-green leaves with white veins are dried in the sun without fermentation, preserving the original alkaloid profile of the young leaf — particularly the high content of mitragynine and speciociliatine.

Young Mitragyna speciosa leaves from Putussibau have a different alkaloid profile than mature leaves. The white veins of young leaves contain proportionally more mitragynine and speciociliatine. As the leaf matures, this profile shifts. By harvesting early, this specific young-leaf profile is captured.
The crucial difference is the absence of fermentation. Red kratom is fermented for days, causing alkaloid oxidation. White kratom is dried directly in the sun after harvest without a fermentation step. This preserves the original alkaloid profile, with a higher proportion of unoxidised mitragynine.

Our white kratom comes from the Putussibau region — located at the upper reaches of the Kapuas River, the longest river in Borneo (1,143 km). The Mitragyna speciosa trees grow on fertile river banks in the tropical rainforest. Young leaves are selectively hand-picked by experienced local farmers who recognise the optimal harvest moment by the colour and texture of the leaf.
White kratom is more susceptible to oxidation than red kratom due to its higher unoxidised mitragynine content. Always store it in an airtight, light-proof container in a cool place (below 25°C). Avoid moisture and direct sunlight. Vacuum sealing is strongly recommended to protect the alkaloid profile.
