What to expect

Taking kratom capsules

How it feels

Many people describe kratom as a smooth, functional shift in how they feel. How much you take shapes the experience, and everyone responds a little differently, so let your first serving be your guide.

Give it time

Everyone responds differently, so there is no set timeline. With capsules, wait at least an hour before taking more.

How to start

Start with 2 capsules with water and wait at least an hour before taking more. Each capsule is pre-measured, so counting capsules keeps your serving consistent.

Good to know

  • Do not combine kratom with alcohol.
  • Use caution when driving or operating machinery until you know how kratom affects you.
  • Talk to a physician before use if you are pregnant, nursing, managing a medical condition or taking medication.
  • Some drug tests can detect kratom.

Must be 21+ to purchase. Like caffeine and sugar, kratom may be habit-forming. Use kratom responsibly and only as directed.

What's inside

Honest ingredients

The dried, milled leaf of Mitragyna speciosa, the kratom tree, sealed inside each Green Borneo capsule. Of the leaf's natural alkaloids, mitragynine is the most abundant.

How

How Does It Work?

Green Borneo is kratom leaf powder in pre-measured capsules, so you count capsules rather than weigh powder. Take two with water and wait at least an hour before deciding on more. Responses vary from person to person, so build from that first serving.

When

When Do I Use It?

Many people reach for Green Borneo during the working day, from the morning into the afternoon. A bag tucks into a desk drawer or work bag, with no powder to measure or taste.

Good to know

Questions, answered

Where does Green Borneo land on the strain spectrum?

Right in the middle. The bag prints Green Vein, and green is fourth of seven on our kratom strain spectrum: White, Aged, Mixed, Green, Yellow, Orange, and Red. Many people choose Green Borneo for the working day.

What is a good first serving of Green Borneo?

Two capsules with water. Give it at least an hour before you decide on more. From there, four capsules is the middle of the range and six is the top. Like caffeine and sugar, kratom may be habit-forming. Use kratom responsibly and only as directed.

Which size is right for me?

To try Green Borneo, the 10 capsule bag covers five starting servings of two. If it becomes a regular, larger bags cost less per capsule, and you can subscribe and save on deliveries every 7, 14 or 30 days.

Is Green Borneo third-party 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 Borneo, so it is not a test of No. 445 alone. It is also linked on this page.

How should I keep Green Borneo capsules?

Store the sealed bag in a cool, dry place away from direct sunlight, and keep it 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 much kratom should I take?

There is no single answer, because everyone responds differently. Start with the lowest serving on the product page and give it time before deciding on more. Smaller servings are commonly chosen for a lift and larger servings for winding down. 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 with the lowest serving on the product page and give it time before taking more: at least an hour for capsules, and at least 30 minutes for other formats.

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.
