Maeng Da Collection The story behind the colours
The Maeng Da Collection is Kratomvia's range of Maeng Da kratom powder in four colours: white, green, yellow and red. Here is what the colours mean, how a batch goes from leaf to lab report, and how the four pack sizes compare.
Last updated: 7 November 2026
Four colours, one grade and a lab report for every batch. These are the figures behind the Maeng Da Collection.

One grade, four colours
Kratom is often sold under long rows of regional names: Borneo, Bali, Malay, Thai. Each name says where a leaf was grown or traded, and a shop can carry dozens of them. Kratom strains explained goes through the most common ones.
The Maeng Da Collection is built the other way round. It is one selected grade, Maeng Da, from one known supply chain in Southeast Asia, offered in four colours.
Keeping to one grade and one supply chain has a practical reason. Every batch can be traced back to its own lab report instead of a mix of regional stock.
What changes between the four is the colour. And the colour comes from two things: when the leaf is picked and how it is dried.
From leaf to powder
The colour of a Maeng Da powder is decided long before it reaches a pouch. Four steps shape every batch.
One Maeng Da grade from one known supply chain in Southeast Asia.
Leaves are picked at the stage of growth that sets the colour.
Gently, longer or quickly, depending on the colour.
Milled into a fine, even powder, then tested batch by batch.
Select
Maeng Da is a selected grade of Mitragyna speciosa known for large, mature leaves. All four colours in the collection come from the same grade and the same supply chain, so the differences between them come from harvest and drying, not from mixing regions.
Harvest
White leaves are harvested earlier, while the veins are still pale. Green leaves are usually picked in the middle of their growth cycle. Red leaves are usually picked when they are fully mature.
Dry
Green leaves are dried gently, mostly indoors and out of direct sunlight, so the powder keeps its bright green colour and fresh, grassy aroma. White leaves are dried quickly indoors, away from sunlight. Red leaves are dried for longer, which gives the powder its darker, reddish-brown tone. Yellow is usually made from green or white leaves that are dried for longer or in a special way.
Mill
All four are milled into a fine, even powder. A sample from every finished batch then goes to an independent, accredited laboratory, and the batch is approved for sale only once it passes. The checks are shown under five steps, every batch below.

What the colour actually means
Green, red and white describe the vein colour and how the leaf was dried. They are not different plants: all four powders in the collection come from the same Maeng Da grade.
Yellow is the exception. It is not a separate vein colour on the tree but a processing style, and the method varies a lot between producers.
So the colour is a good guide to how a batch was made. It says nothing about heavy metals, microbes or moisture. That is the job of the lab report.
The colour tells you how a batch was made. The lab report tells you what is in it.
How a Kratomvia pouch is labelled
- The logoKRATOMVIA in black capitals at the top, with a small leaf on the final A.
- The illustrationA seated Buddha among green leaves, framed by a thin gold halo and gold ornaments at the sides. It is the same on all four pouches.
- Premium QualityWritten in black script just above the name.
- The namePrinted in a tone of its own: grey for White, green for Green, olive for Yellow and red for Red.
- Weight and batchThe weight sits under the name, followed by www.kratomvia.com. Each package also carries a batch number printed on the label.
A language of colours
Maeng Da is a Thai expression, usually translated as slang for an especially high grade. Growers in Thailand used it for trees and leaves that stood out, and the name spread with the kratom trade. Today most Maeng Da is grown in Indonesia and Malaysia, but the name has stuck as a mark of a premium grade.
Within the collection, the colours do the job that long product names do elsewhere. Four colours are easy to tell apart and easy to remember, and they fall into a clear order, from the pale White to the reddish-brown Red.
Four colours. One grade. One lab report per batch.
Four tones, one for each colour, from early harvest to fully mature.
Four colours of Maeng Da
All four colours come in the same four pack sizes, 100 g, 250 g, 500 g and 1000 g, at the same prices. Pick a pack size directly under each colour.

Read the full guide to Maeng Da kratomWhat is Maeng Da?
Maeng Da is not a separate plant species but a selected grade of kratom (Mitragyna speciosa), known for large, mature leaves and a strong alkaloid profile. It is sold in several vein colours: red, green, white and yellow.
There is no single official definition, which is why quality varies so much between shops. In practice, good Maeng Da has three things in common: mature leaves, selected trees and careful processing.
Regional names work differently. Names such as Borneo, Bali, Malay or Thai describe where a leaf was grown or traded, not a grade. Read more in Maeng Da kratom: what it is and how it differs.
| Maeng Da | Regional names | |
|---|---|---|
| Describes | A selected grade with large, mature leaves | Where a leaf was grown or traded |
| Colours | White, green, yellow and red | Several per region, e.g. Red Bali, Green Malay |
| At Kratomvia | One grade from one known supply chain | Not sold as separate products |
| Traceability | Every batch has its own lab report | Depends on the seller |
What you can't see in a powder
Colour, aroma and texture tell you how a batch was made. They don't tell you what else might be in it.
Heavy metals can be present in soil and build up in plant material during growth. Microbial contamination can develop if harvesting, drying or storage conditions aren't controlled. Some suppliers dilute powder with fillers to cut costs.
Independent laboratory testing is the only reliable way to confirm what is inside a package before it is sold. Independent matters, because a lab with no commercial relationship to the seller has no reason to produce a favourable result.
That is why every batch in the collection goes to an independent, accredited laboratory before it is approved for sale. Checked batch by batch, not sampled occasionally. Our guide explains how kratom lab testing works.
Five steps, every batch
A sample from every finished batch goes through four lab tests before the batch is approved for sale.
See the lab reports >The sample is drawn following a documented chain of custody from warehouse to laboratory. Alkaloid analysis by HPLC (high-performance liquid chromatography) confirms that the profile matches Mitragyna speciosa. Heavy metal screening covers lead, arsenic, cadmium and mercury, and the microbiological test checks for Salmonella, E. coli, yeast, mould and other Enterobacteriaceae. Moisture is measured to confirm the batch sits within a stable range.
A batch that fails any of these checks is not sold, no matter how far along the supply chain it already is.
Each lot also has a product specification, and our e-beam treatment is certified by the irradiation facility. Both are on the lab reports page.
How to store Maeng Da powder
Store it airtight, cool, dark and dry. Moisture and air wear a batch down fastest, so keep the pouch tightly closed.
Kept sealed and dry, kratom powder typically stays fresh for roughly 12 to 24 months. Once opened, expect a shorter window of about 6 to 12 months. Read more about kratom shelf life.
