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.

Questions, answered

What does Aged Strain mean on the No. 471 bag?

Dark Green Borneo is dried longer than traditional Green Borneo, and the bag prints it as an Aged Strain. Our kratom strains run White, Aged, Mixed, Green, Yellow, Orange, Red, so No. 471 sits second on that list rather than with the Green Vein strains. Many people choose it for the daytime and afternoon.

How many capsules should I start with?

Two, with water. Wait at least an hour before you decide on more. 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 bag size makes sense to start?

The 10 capsule bag holds five 2-capsule starting servings, enough to get to know Dark Green Borneo. Larger bags cost less per capsule, and the size picker shows the price per capsule for each one. Subscriptions deliver every 7, 14 or 30 days, and subscribers save.

Has No. 471 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 Dark Green Borneo, so it is not a test of No. 471 alone. It is also linked on this page.

How should I keep the capsules fresh?

Keep the bag sealed and store 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 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.
