No 431 White Sumatra Kratom Capsules

We line up kratom strains as White, Aged, Mixed, Green, Yellow, Orange and Red. No. 431 White Sumatra carries a White Vein label, at the start of that line, and many people choose it for later in the day.

Start low, go slow, and take them with water. Give it 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.

Start with the 10 capsule bag: five 2-capsule servings, enough to learn how White Sumatra suits you. If it becomes a regular, the larger bags cost less per capsule. Subscriptions deliver every 7, 14 or 30 days.

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 Sumatra, so it is not a test of No. 431 alone. It is also linked on this page.

Seal the bag after each use and keep it somewhere cool and dry, out of direct sunlight. Store it out of reach of children and pets.

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.

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.

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.

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.

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.
