Questions, answered

What is No. 537 Kratom Seltzer?

No. 537 is a ready-to-drink kratom seltzer made with full spectrum kratom alkaloids. Each 16oz can delivers 75mg of mitragynine in a refreshing black cherry flavor with zero calories.

How much kratom is in each can?

Each 16oz can contains 75mg of mitragynine from full spectrum kratom extract. The serving size is half a can (8oz) which contains 37.5mg. The alkaloid composition is less than 2% 7-hydroxymitragynine.

What does it taste like?

No. 537 has a bold, refreshing black cherry flavor with crisp carbonation. It's light, bubbly, and easy to drink. Naturally flavored with other natural flavors.

How should I drink it?

Shake gently before opening and serve chilled. If you're new to kratom, start with half a can to assess your tolerance and wait at least 30 minutes before consuming more. Refrigerate after opening.

Is it safe to mix with alcohol?

No. Do not combine or mix this product with alcohol. Consume responsibly and discontinue use if you experience any negative effects.

What is a kratom drink?

It is a ready-to-drink beverage made with kratom leaf extract. Nothing to measure, nothing to mix. Kratom comes from the leaves of the Mitragyna speciosa tree, native to Southeast Asia, where it has been enjoyed for centuries. Think of it as the middle ground between coffee and a beer: alert but relaxed, social but clear-headed.

How much is one serving?

One can or bottle is one full serving, so drink the whole thing or share it, your call. Check the label for the amount of kratom extract in each container, and start with less if it is your first time. Like caffeine and sugar, kratom may be habit-forming. Use kratom responsibly and only as directed.

How fast does it work?

Effects typically begin within 15 to 30 minutes, since a liquid absorbs faster than powder or capsules. How long it lasts varies from person to person. Give it the full window before you open another.

Can you ship kratom drinks 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, and our checkout will flag an address we are not able to ship kratom to. The current list of restricted areas is in our site footer. Shipping costs on beverages are calculated at checkout.

Can I pick it up in store?

Many kratom drinks are available for in-store pickup, and singles are often easier to find on the shelf than online. Choose the pickup option on this page or at checkout to see which nearby locations have it in stock.
