Kratom Powder

White kratom is made from younger leaves that undergo a shorter fermentation process, producing a lighter-coloured powder. At 2.01% total alkaloid content, Great White comfortably sits above the two-percent threshold.

Alkaloid Profile: More Complex Than You'd Expect

Great White has a profile that defies the usual white-kratom stereotype. Mitragynine at 1.27% accounts for 63.2% of total alkaloids, solid, but notably lower in mitragynine dominance than White Elephant (67.9%). The interesting part is the speciociliatine: at 0.36%, representing 17.9% of total alkaloids, Great White carries the highest speciociliatine ratio of any white strain we test. Speciociliatine is the diastereomer of mitragynine that typically features more prominently in red strains. Its elevated presence in Great White gives this white a more complex character than its colour would suggest, paynantheine (0.22%) and speciogynine (0.15%) round out a well-distributed secondary alkaloid base.

Alkaloid Profile: The Mitragynine Leader

Here is what makes Green Hulu Kapuas genuinely remarkable: at 1.60% mitragynine representing 68.7% of total alkaloids, it has the highest mitragynine-dominance ratio of any strain we carry. In practical terms, this means Green Hulu Kapuas is the most mitragynine-concentrated product in our range. The paynantheine (0.28%) and speciogynine (0.19%) levels are also among the highest in our collection, while speciociliatine is proportionally lower (11.8% of total) than in any other strain.

The slow-growth conditions along the Kapuas River, cooler temperatures, shaded forest, river-fed soil, appear to favour a clean, mitragynine-led profile with less of the alkaloid diversity you see in sun-dried, fermented reds. This is what makes Hulu Kapuas varieties sought after by experienced customers.

Testing and Availability

Lab-tested and sterilised. Available as powder and capsules. Note that availability may vary by season due to the limited supply from the Kapuas region. Also included in our Sample Package I (180g).

This rare kratom powder comes from ancient trees that grow deep in the jungles of the Malay Peninsula - one of the original regions of the Mitragyna speciosa tree. Green Malay is where most customers start their journey into green kratom, and many never leave.

Alkaloid Profile: Balanced by Nature

Lab testing shows Green Malay at 1.93% total alkaloid content with 1.25% mitragynine, accounting for 64.8% of the total profile. What distinguishes Green Malay from other greens is its balance, no single secondary alkaloid dominates. Paynantheine sits at 0.22%, speciogynine at 0.14%, and speciociliatine at 0.33%. This even distribution across the alkaloid spectrum is consistent with how users describe Green Malay: versatile and well-rounded, sitting in the middle ground between red and white strains. Paynantheine and speciogynine are both associated with serotonin 5-HT1A receptor affinity in published research, which may contribute to the balanced character Green Malay is known for.

The Malay Peninsula Origin

The Malay Peninsula has the longest continuous history of kratom cultivation alongside Indonesia. The fertile lowland soils produce leaves with a naturally balanced alkaloid profile that has made Green Malay a global standard. Lab-tested and gamma-sterilised after vacuum packaging. Also available as Green Malay capsules. Explore our full green kratom range.

Sourced from the Jongkong region in western Borneo, this white strain delivers one of the highest alkaloid concentrations in our entire collection: 2.37% total alkaloids.

Alkaloid Profile: Mitragynine Powerhouse

White Elephant's lab results are striking. Mitragynine at 1.61% accounts for 67.9% of total alkaloids, the third-highest mitragynine reading in our range and the highest of any white strain. Paynantheine at 0.28% and speciogynine at 0.19% match the levels found in Super Maeng Da, our overall alkaloid leader. Meanwhile, speciociliatine at 0.30% accounts for just 12.5% of the total, the second-lowest speciociliatine ratio of any strain we carry. The result is a clean, mitragynine-led profile with strong secondary alkaloid support from the serotonin-associated paynantheine and speciogynine.

The Jongkong Origin

The Jongkong region sits along the Kapuas River in West Kalimantan, Indonesia. The combination of river-fed soil, tropical humidity, and old-growth forest canopy creates growing conditions that produce especially alkaloid-rich leaves.

At 1.57% total alkaloid content and 0.99% mitragynine, Red Borneo Classic delivers a different expression of the Borneo terroir compared to our standard Red Borneo.

Alkaloid Profile: A Different Borneo Character

Where our standard Red Borneo leads with a high mitragynine-dominance ratio (66.7%), Red Borneo Classic takes a different shape. Mitragynine at 0.99% accounts for 63.3% of total alkaloids,lower mitragynine dominance means the secondary alkaloids play a proportionally larger role in the overall composition. Speciociliatine at 0.26% (16.7% of total), paynantheine at 0.18%, and speciogynine at 0.14% contribute more meaningfully to the alkaloid fingerprint. The result is a broader, more distributed profile rather than a mitragynine-led one.

Many of our customers enjoy alternating between Red Borneo and Red Borneo Classic,same origin, different character. The contrast highlights how tree age, leaf selection, and processing can shape the alkaloid composition even within the same region.

Lab-Tested and Sterilised

Every batch independently tested for alkaloid content and heavy metals. Gamma-sterilised after vacuum packaging at our facility in the Netherlands. Also available as capsules.

This organic kratom powder is sourced from mature trees in the primary and secondary rainforests of central Borneo (Kalimantan), Indonesia, one of the oldest rainforests on the planet, estimated at 140 million years old. The mature red-veined leaves go through an extended drying and fermentation process that shapes the alkaloid composition into a profile characteristic of red kratom varieties.

Alkaloid Profile

Our lab analysis shows Red Borneo at 1.92% total alkaloid content, the highest total of any standard red strain in our collection. Mitragynine leads at 1.28%, accounting for 66.7% of the total profile, one of the highest mitragynine-dominance ratios among our reds. Paynantheine (0.20%) and speciogynine (0.14%) provide a secondary layer, both associated in published research with serotonin 5-HT1A receptor affinity. Speciociliatine sits at 0.30%, representing 15.7% of total alkaloids, a moderate ratio that balances mitragynine dominance with enough of its diastereomer to give Red Borneo a distinctly red character.

You may see this kratom sold elsewhere as "Bali Kratom." That name is misleading. There are virtually no kratom plantations on the island of Bali. What most vendors sell as Bali Kratom is simply Red Borneo by another name. At Kraatje, we name our products honestly, by region of origin and colour.

Quality and Testing

Every batch is independently lab-tested for alkaloid content and heavy metals at our facility in the Netherlands. After vacuum packaging, each bag is treated with gamma radiation sterilisation — eliminating any possibility of microbial contamination. Also available as Red Borneo capsules. Explore our Red Borneo Classic for an alternative Borneo red, or try the sample package to compare nine strains side by side.

Alkaloid Profile

Lab analysis shows 1.54% total alkaloid content with mitragynine at 0.95%, making up 61.6% of the total, one of the lower mitragynine-dominance ratios in our range. This means the secondary alkaloids, paynantheine (0.17%), speciogynine (0.13%), and speciociliatine (0.29%), play a proportionally larger role in the overall composition. The speciociliatine-to-mitragynine ratio of 0.31 is among the highest across all our strains, giving Red Hulu Kapuas a more complex and varied alkaloid fingerprint than strains where mitragynine dominates more heavily.

The slow-growth environment along the Kapuas River gives the leaves more time to develop. Availability varies by season. When we secure a batch that passes our testing standards, we stock it.

Alkaloid Profile: A Sumatran Signature

Red Sumatra registers 1.37% total alkaloids, with mitragynine at 0.85% accounting for 61.7% of the total. The secondary alkaloid ratios tell the story of Sumatra's different growing environment: paynantheine at 0.15% and speciogynine at 0.12% show the same proportional balance as Borneo reds, but speciociliatine at 0.26% (19.1% of total alkaloids) gives Red Sumatra one of the highest speciociliatine ratios in our range. Research suggests speciociliatine has a distinct binding profile from mitragynine due to its different stereochemistry. The volcanic soil composition of Sumatra, enriched by centuries of volcanic activity, likely contributes to these regional alkaloid differences.

Tested and Ready to Ship

Less widely available than our Borneo reds because fewer Sumatran farms meet our quality standards. Lab-tested for alkaloid content and heavy metals, gamma-sterilised after vacuum packaging. Also available as capsules. Explore our full red kratom collection.

What the Alkaloid Profile Reveals

Mitragynine sits at 1.14%, accounting for 63.3% of total alkaloids. But what makes Red Thai Maeng Da particularly interesting is its speciociliatine content, at 0.33%, it is the highest absolute speciociliatine level of any red strain we carry, and at 18.5% of the total profile, it contributes meaningfully to the character. Speciociliatine is the C3 diastereomer of mitragynine, meaning it has the same atoms but arranged differently in three-dimensional space. Research suggests this structural difference results in a distinct receptor binding profile. The combination of relatively high mitragynine and high speciociliatine gives Red Thai Maeng Da a more layered alkaloid composition than simpler reds.

The Maeng Da Name

"Maeng Da" was coined by an American distributor and has become the most recognised name in kratom. In 1943, Thailand banned kratom cultivation, pushing production to Indonesian farms. Our Red Thai Maeng Da comes from these lineage trees, real Thai genetics, not a marketing invention. We use the name honestly.

Lab-Tested and Sterilised

Every batch independently tested for alkaloid content and heavy metals. Gamma-sterilised after vacuum packaging. Also available as Red Thai Maeng Da capsules. Explore the sample package to compare this strain against eight other varieties.

At Kraatje, we recognised years ago that the stems and veins contain their own distinct alkaloid composition and deserve a product of their own.

Alkaloid Profile: A Radically Different Composition

This is where Stem and Vein stands apart from everything else in our range. Total alkaloid content is 1.22%, which places it in the lower end numerically. But the ratios are unlike anything else we carry.

Speciociliatine at 0.49% makes up 39.8% of total alkaloids, more than double the proportion seen in any other strain in our collection (the next highest is 19.8%). Meanwhile, mitragynine at 0.55% accounts for only 45.2% of total alkaloids, in every other strain, mitragynine represents 61-69% of the total. The speciociliatine-to-mitragynine ratio is 0.88, meaning these two alkaloids are present in nearly equal amounts. In a typical strain like Green Borneo, that ratio is 0.19.

This is not a weaker version of regular kratom. It is a fundamentally different product with a fundamentally different alkaloid fingerprint. Speciociliatine is the C3 diastereomer of mitragynine, same atoms, different three-dimensional arrangement, and published research suggests it interacts with receptors differently than mitragynine itself. The near-equal mitragynine-to-speciociliatine ratio in Stem and Vein is something you will not find in any leaf-based kratom powder.

How Customers Approach Stem and Vein

Experienced users commonly add Stem and Vein into their rotation alongside regular strains. The radically different alkaloid balance means it provides genuine variety rather than simply more of the same. Some users mix Stem and Vein with a standard powder to create a custom profile. Lab-tested and gamma-sterilised after vacuum packaging, same quality standards as all our products.

 These are not standard harvest batches. Super Green delivers a noticeably more robust green experience than our regular Green Borneo.

Alkaloid Profile: The Speciociliatine-Rich Green

What sets Super Green apart from other greens in our range is its speciociliatine content. At 0.37% speciociliatine, representing 18.9% of total alkaloids, it has the highest speciociliatine ratio of any green strain we carry. This brings Super Green closer to the alkaloid balance you typically see in red strains, where speciociliatine plays a more prominent role. It is an unusual profile for a green and may account for why experienced users often describe Super Green as having more depth and complexity than a typical green like Green Borneo (where speciociliatine is only 13.2% of total).

Mitragynine still dominates at 62.9% of the total profile, with paynantheine (0.22%) and speciogynine (0.15%) in their expected supporting roles. The net result is a green that is concentrated, complex, and genuinely distinct from its peers.

What Makes It "Super"

The "super" label at Kraatje is not a marketing gimmick. It refers to a specific leaf selection process: only the most alkaloid-rich leaves from a harvest are used. This selective approach produces a more concentrated product, which is why Super Green appeals particularly to experienced customers looking for a step up.

For enthusiasts wanting even more, our Premium Edition kratom blend combines Super Green with a special kratom extract for added strength. It is available in the Specials section.

The "super" label is earned, this is leaf selected specifically for its above-average alkaloid density from harvests that already begin with strong baseline numbers.

Alkaloid Profile: The Numbers Leader

Mitragynine at 1.62% accounts for 66.9% of total alkaloids, firmly in the upper range. But what makes Super Maeng Da distinctive is not just the mitragynine. Its secondary alkaloids are also elevated: paynantheine at 0.27% and speciogynine at 0.19% are among the highest absolute values in our range. Published research associates both paynantheine and speciogynine with serotonin 5-HT1A receptor affinity, suggesting they contribute to the broader character profile that users describe in whole-leaf kratom. Speciociliatine sits at 0.34% (14.1% of total), moderate for the range, the profile leans toward the mitragynine-led end rather than the speciociliatine-rich end you see in some reds.

At Kraatje, "Maeng Da" refers to a genuine Thai-origin variety, not a marketing label. And "super" means verifiable above-average alkaloid content. These are not empty words, the lab data on this page proves that.

Alkaloid Profile: Speciociliatine-Forward

What makes Super Red Borneo interesting is not the total alkaloid concentration but the ratio. Mitragynine at 0.64% accounts for 61.6% of total alkaloids, one of the lower mitragynine-dominance ratios in our collection. Speciociliatine, at 0.21% and 19.8% of the total profile, is among the highest speciociliatine ratios we carry. This means the secondary alkaloids play a proportionally larger role than in our mitragynine-led strains. Speciociliatine is the C3 diastereomer of mitragynine, same molecular formula, different three-dimensional structure and research suggests it interacts with receptors differently. The result is a red kratom with a character that is distinctly its own.

Paynantheine (0.11%) and speciogynine (0.08%) are present at lower absolute levels but maintain their proportional balance within the profile.
