Overview

Korthals' Collection No. 488 Green Sumatra is a Green Vein kratom in pre-measured capsules. It may offer a balanced mix of energy and tranquility, and many people choose it for the late morning into the afternoon.

What's inside

Honest ingredients

Each Green Sumatra capsule holds dried, milled leaf of Mitragyna speciosa, the kratom tree. Mitragynine is the most abundant of the leaf's natural alkaloids.

How

How Does It Work?

Each Green Sumatra capsule is filled with kratom leaf powder, so a serving is a number of capsules, not a scoop. Start low, go slow. Take them with water and wait at least an hour before you decide on more. Everyone responds differently.

When

When Do I Use It?

Many people choose Green Sumatra from the late morning into the afternoon, when the day still has a few hours left in it. Capsules ride along in a bag or jacket pocket and skip the taste of powder altogether.

Good to know

Questions, answered

Where is Green Sumatra on the strain spectrum?

Green Sumatra is printed as a Green Vein. On our kratom strain spectrum of White, Aged, Mixed, Green, Yellow, Orange, and Red, that is the middle position, fourth of seven. It tends to be an afternoon pick.

How should I start?

Start low, go slow, and take them with water. Wait at least an hour before deciding on more. Like caffeine and sugar, kratom may be habit-forming. Use kratom responsibly and only as directed.

What size bag should I get?

The 10 capsule bag is the smallest size, enough to see whether Green Sumatra fits your routine. Larger bags cost less per capsule, and you can subscribe and save on deliveries every 7, 14 or 30 days.

Has Green Sumatra been lab tested?

Yes, as part of our green kratom testing. Murray-Brown Laboratories, an independent lab, tested a sample described as Korthals Green Kratom for its alkaloid content; the certificate is dated December 2025. Our Test Results page lists that same certificate for several strains, including Green Sumatra, so it is not a test of No. 488 alone. It is also linked on this page.

What is the right way to store it?

Keep the bag closed and in a cool, dry place, 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.
