Overview

Korthals' Collection No. 424 White Borneo is a White Vein kratom in pre-measured capsules, ready to take without a scale or a scoop. It may offer comfort and focus, and many people choose it to stay calm through the working day.

What's inside

Honest ingredients

Dried, finely milled leaf of Mitragyna speciosa, the kratom tree, filled into capsules. Mitragynine is the most abundant natural alkaloid in the leaf.

How

How Does It Work?

White Borneo comes as kratom leaf powder packed into capsules, so a serving is simply a count. Start low, go slow. Take them with a glass of water and wait at least an hour before deciding whether to take more. People respond to kratom differently, and pacing yourself is the simplest way to find your serving.

When

When Do I Use It?

Many people choose White Borneo for the first half of the day, from an early start to a long stretch at work. The capsules fit easily into a backpack, a briefcase or a desk drawer, and they skip the taste of raw powder.

Good to know

Questions, answered

Which strain line is No. 424 White Borneo?

Our kratom strain spectrum runs White, Aged, Mixed, Green, Yellow, Orange and Red. No. 424 White Borneo is printed as a White Vein, the first stop on that spectrum, and many people choose it for the daytime.

How should I start with White Borneo?

Start low, go slow. Take them with water and wait at least an hour before deciding on more. Never take more than you planned. Like caffeine and sugar, kratom may be habit-forming. Use kratom responsibly and only as directed.

Which bag size should I choose?

The 10 capsule bag is the smallest size, an easy way to get to know White Borneo. The 30, 90, 180 and 360 capsule bags cost less per capsule as they get larger. You can also subscribe and save, with deliveries every 7, 14 or 30 days.

Is No. 424 White Borneo lab tested?

Yes, as part of our white kratom testing. Murray-Brown Laboratories, an independent lab, tested a sample described as Korthals White Kratom for its alkaloid content; the certificate is dated December 2025. Our Test Results page lists that same certificate for several strains, including White Borneo, so it is not a test of No. 424 alone. It is also linked on this page.

Where should I keep my White Borneo capsules?

Store the sealed bag somewhere cool and dry, out of direct sunlight and out of reach of children and pets.

What is kratom?

Kratom comes from the leaves of the Mitragyna speciosa tree, native to Southeast Asia, where it has been part of daily life for centuries. The leaf is dried and milled into powder, then packed into capsules, brewed, or made into extracts. Its natural leaf compounds are called alkaloids, and mitragynine is the most abundant one.

How should I start with kratom?

There is no single answer, because everyone responds differently. Start low, go slow, and give it time before deciding on more. A small kitchen scale helps if you are using powder. Like caffeine and sugar, kratom may be habit-forming. Use kratom responsibly and only as directed.

How long should I wait before taking more?

Everyone responds differently, so there is no set timeline. Start low, go slow: wait at least an hour after capsules, and at least 30 minutes after other formats, before taking more.

Can you ship kratom to my state?

We cannot ship kratom to Tennessee. Kratom is also restricted in a handful of other states and in some counties and cities. Our checkout will flag an address we are not able to ship kratom to, and the current list of restricted areas is in our site footer. If you are in a restricted area, our stores and our non-kratom selection are still open to you.

Can I pick it up in store?

Many kratom items are available for in-store pickup, and shelf selection can differ from what is online. Choose the pickup option on this page or at checkout to see which nearby locations have it in stock.
