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

Overview

Korthals' Collection No. 657 Kratom Extract Softgels hold kratom extract in a softgel, 10 to a box, and one softgel is one serving. The box marks them for experienced kratom consumers, so they are not the place to start with kratom. The Murray-Brown Laboratories certificate for No. 657 is linked on this page.

What's inside

Honest ingredients

Kratom is a plant, not a synthetic. Its most abundant natural alkaloid is mitragynine, alongside other compounds that occur in the leaf. Where a third-party certificate of analysis is available, it is linked on the product page, and our published lab results are on our Test Results page.

How

How Kratom Works

Kratom comes from the leaves of the Mitragyna speciosa tree, native to Southeast Asia, where it has been enjoyed for centuries. Its natural leaf compounds, called alkaloids, interact with the body in a way many people describe as a smooth, functional shift in how they feel. Everyone responds a little differently, so start low, go slow.

Good to know

Questions, answered

How much kratom is in each serving?

Each softgel is one serving of kratom extract, and each box holds 10. The ingredients printed on the box are MCT, gelatin, glycerin, beeswax, sunflower lecithin, purified water and kratom extract. The Murray-Brown Laboratories certificate linked on this page reports the alkaloids measured in a sample of No. 657.

How should I take the extract?

One softgel is one serving, as the box directs. Start low, go slow: wait at least an hour before deciding whether to take another, and never take more than you planned. Like caffeine and sugar, kratom may be habit-forming. Use kratom responsibly and only as directed.

Are there any side effects I should know about?

Follow the warning on the box. Do not use it if you are under 21, pregnant or lactating, and talk to a physician first if you have a medical condition or take any medication. Do not combine or mix it with alcohol, use caution when operating machinery, stop if you notice any negative effects, seek medical help in an emergency, and keep it out of reach of children and pets.

Is this product good for beginners?

No. The box states that No. 657 is intended for experienced kratom consumers. If you are new to kratom, look at our Korthals' Collection leaf capsules instead, and start low, go slow.

How should I store this product?

Store the box at room temperature, as the label directs, 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 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.
