To enjoy dried kratom powder to the fullest and retain its maximum health benefits, you should ensure you store your kratom properly. This begs the question: does kratom expire? Here, the experts at Kratora will answer all your questions about kratom degradation, kratom shelf life, and kratom expiration. Learning as much as you can about the herb is the best way to ensure you have the best experience possible!

Does Kratom Expire?

In short, yes, kratom does expire. Kratom is a plant, and like all living matter, it will naturally decay over time. When kratom is properly dried and preserved, however, it can last for an impressive amount of time.

Think of kitchen herbs. Many people are unaware that their store-bought spices expire, but over time, even well-dried and preserved herbs can lose their flavor and any potential benefits. Have you ever tried to use a ten-year-old jar of oregano only to find that not only did it fail to enhance your meal, but it also had a stale, unpleasant flavor? Likewise, have you ever brewed a cup of tea with an old teabag you found in the back of the pantry, only to find the taste was less than satisfactory, and the caffeine wasn’t hitting your system at all?

The same can happen with kratom expiration. Expired kratom is not likely to hurt you, but it’s not going to have the same taste or desired effects.

Additionally, certain chemical effects can cause kratom to expire. Prolonged exposure to oxygen can cause the alkaloid mitragynine, found in kratom, to degrade into a less effective substance. We’ll go through how to store your kratom properly below.


How long does kratom last?

This answer can be surprisingly complex because it depends on a variety of factors:

  • The strain of kratom
  • How the kratom is preserved (e.g. dried powder, liquid, or capsules)
  • In what temperature, light, and humidity you store the kratom
  • In what container you store the kratom
  • Where you purchased the kratom from

Generally, kratom powder can last several months if kept in optimal conditions. The more recently your kratom was growing fresh in the ground, the better, so try to buy only as much kratom as you think you’ll need in the next few months. If you have multiple people in your household using kratom on a regular basis, you shouldn’t have to worry about kratom expiration if you follow the right storage advice and purchase your kratom regularly.

For kratom capsules and liquid kratom, the manufacturing process can vary. There is no universal instruction we can recommend for these products because of how widely they vary, so find this information on your individual product. No matter the type of kratom you purchase, always refer to the kratom shelf life details on your individual package!

When kratom does expire, can it harm me?

There’s a difference between the questions “does kratom expire” and “can kratom go bad?” “Expired” just means that kratom is past its sell-by date. But that doesn’t mean it’s actually harmful.

Expired kratom won’t hurt you, but it won’t have the same potency, either. If you use kratom after the recommended shelf life is over, you’re unlikely to experience the maximum benefits that make kratom use so popular, such as:

Mold, however, can make you very sick. Throw away moldy kratom. Do not use kratom exposed to moisture and fallen victim to any kind of mold. It’s not enough to pull off the mold and use the kratom beneath: any amount of kratom that has been partially exposed to mold can contain microscopic, invisible spores that can be just as harmful. Don’t risk it!

How can I best preserve and store my kratom?

For dried kratom, store it much in the way you would store fine herbs or tea leaves. So your kratom doesn’t expire prematurely, follow these instructions:

  • Keep kratom in a cool, dry place.
  • Do not freeze or refrigerate your kratom, as that can introduce moisture and promote mold.
  • Keep it away from direct UV light.
  • Store kratom in an airtight container to minimize oxygen exposure.
  • Purchase your kratom from a trusted, high-quality supplier.
  • When storing a new package of kratom, don’t mix it with the old kratom — use a separate container, or empty the old one first.

This is just a brief overview of correct kratom storage. To best avoid kratom expiration, read our extensive guide on how to store your kratom properly.

Buy your kratom from a trusted source

Can kratom go bad? Yes it can. But the best way to ensure your kratom will stay fresher for longer is to purchase it from a trusted source. The higher quality the kratom is from the moment it starts growing in the ground, the longer the kratom shelf life you’ll have.

Frequently Asked Questions

How can I tell if my kratom has mold? 

The two best tests for moldy kratom are the sight test and the smell test. Certain types of mold, like powdery mildew, are easy to identify on account of their splotchy white and gray appearance. Other types of mold might look like a thin spider web or subtle discoloration. If your kratom smells musty (like a wet basement), this is another sign that you need to toss the product in the garbage.

How can I know if kratom is fresh when I buy it? 

Some kratom products will have a date of harvest posted on the packaging. If this information isn’t available, check the date on the 3rd party lab report. Kratom is generally lab-tested shortly after harvest, so this should give you some indication of the product’s freshness.

How does a kratom’s strain affect its longevity? 

Different kratom strains have different concentrations of key alkaloids like mitragynine and 7-hydroxymitragynine. These concentrations may have an effect on how long kratom remains potent (as higher alkaloid concentrations are traceable for longer amounts of time), but this difference is usually minimal. For instance, Maeng Da kratom may retain potency for longer than many other strains, and kratom extracts are likely to maintain measurable potency for longer than standard kratom products.
