Overview

Known for its potential to provide full-body comfort and relaxation, Red Sumatra is a popular choice for evening relaxation. No. 457 is printed as a Red Vein on the Korthals' Collection bag, and each capsule is pre-measured, so a serving is simply a count.

What's inside

Honest ingredients

Mitragyna speciosa leaf, dried and milled into a fine powder, then packed into capsules. The No. 457 bag prints Red Sumatra as a Red Vein. Mitragynine is the most abundant of the natural alkaloids found in kratom leaf.

How

How Does It Work?

Red Sumatra comes as leaf powder packed inside pre-measured capsules, so counting capsules is how you set your serving. Start low, go slow. Take them with water and give it at least an hour before you decide on more. People respond to kratom differently.

When

When Do I Use It?

Many people choose Red Sumatra for the evening, once the workday is behind them. Because every serving is already measured, the capsules are easy to keep on hand, with no scoop, no shaker and no powder taste. Not for anyone under 21, and never mix kratom with alcohol.

Good to know

Questions, answered

Where is No. 457 Red Sumatra on the strain spectrum?

We list kratom strains in this order: White, Aged, Mixed, Green, Yellow, Orange and Red. The No. 457 bag is printed Red Vein, which puts Red Sumatra at the red end of the spectrum. Many people choose it for the evening.

How should I start with Red Sumatra?

Start low, go slow, and wait at least an hour before deciding whether to take more. Like caffeine and sugar, kratom may be habit-forming. Use kratom responsibly and only as directed.

What size bag is right for me?

The 10 capsule bag is the smallest size, a simple way to try Red Sumatra first. Bigger bags bring the cost per capsule down, and the size menu shows it for each option. Subscriptions deliver every 7, 14 or 30 days.

Is No. 457 Red Sumatra lab tested?

Yes, as part of our red kratom testing. Murray-Brown Laboratories, an independent lab, tested a sample described as Korthals Red Kratom for its alkaloid content; the certificate is dated December 2025. Our Test Results page lists that same certificate for several strains, including Red Sumatra, so it is not a test of No. 457 alone. It is also linked on this page.

What is the best way to store the capsules?

Close the bag after each use and keep it somewhere cool and dry, away from 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.
