How To Store Kratom & Make It Last

Kratom has been used for thousands of years for medicinal purposes, and the West is beginning to rediscover how fantastic an herb it really is. But when purchasing kratom powder in bulk, many users fail to properly store their excess kratom, which leads to leftover kratom going to waste.

Here we’ll discuss storing kratom for the short and long term so that you can stop wasting excess kratom and keep it fresh for up to a year!

Things that Impact Kratom Freshness:

  • Exposure to light
  • Exposure to strong odors
  • Exposure to extreme temperatures
  • Exposure to oxygen

Shelf Life of Kratom

Kratom is an organic compound, just like teas and other dried leaves, so kratom’s shelf life is roughly one month. That said, it can certainly be extended through proper storage. But when simply left to be, it will last around one month.

Now it’s important to remember, kratom will not be toxic or deadly if enjoyed after that one month. But, at that point, kratom will have begun to get stale and lose much of its flavor and potent effects. It’s therefore recommended to consume your kratom within one month of purchasing or preparing it for storage.

Things That Affect Kratom’s Shelf Life

The sun’s UV light can be incredibly damaging to our skin, and the same holds true for kratom.

Repeated exposure to UV light can break down kratom’s alkaloids, which are responsible for kratom’s effects. Light, therefore, significantly degrades its potency.


While kratom retains its properties best if stored in a cool place, the most detrimental thing to kratom’s chemical constitution is extreme temperature fluctuations.


Many organic compounds react with oxygen, and kratom is no different. When exposed to oxygen, kratom oxidizes, and the primary alkaloid responsible for kratom’s effects, mitragynine, becomes mitragynine pseudoindoxyl. 

While not toxic, this significantly detracts from kratom’s potency and effects. Saving kratom from oxygen exposure will substantially improve both kratom’s potency and extend your kratom’s shelf life.

Other Odors

Kratom, like other herbs, is susceptible to picking up strong, nearby odors. While the taste of kratom is not what many people would label “appetizing”, you certainly don’t want to add hints of garlic on top of that!

Short-Term Kratom Storage (1-3 Months)


Containers To Store Kratom In

When picking containers to store kratom in, you’ll want to balance storage ability with ease of access. In other words, you won’t want to take all of your kratom out of short-term storage at once, but rather you’ll want to “pick at” your supply.Containers that provide airtight seals which are easy to open and reseal, like mason jars, are excellent choices. Also, ziploc bags that allow you to push excess air out to create a semi-vacuum seal are great options for storing kratom in the short term.

Where To Store Kratom

The best place to store kratom in the short term is somewhere dark that maintains near-constant temperatures. A kitchen pantry or refrigerator are both excellent places to store kratom. 

But remember, you’ll want to store it somewhere relatively accessible so you can easily get to it when you want to take a small amount out for that day’s use.

Long-Term Kratom Storage (3-12 Months)

Storing kratom for the long term means taking short-term kratom storage to the next level. So instead of using a ziploc bag, consider getting a vacuum sealer and using that to seal your kratom. This will ensure maximum kratom shelf life. Also, consider freezing kratom to keep it in a very dark, very temperature-stable environment. 

The ultimate in kratom storage would obviously be putting vacuum-sealed kratom bags in the freezer. But keep in mind that when opening the bags of frozen kratom, you’ll want to allow it to warm up to room temperature before opening in order to avoid thawing in the presence of excess humidity.

We generally don’t recommend storing kratom for longer than 12 months, as even well-stored kratom begins to deteriorate at this point.


How To Check If Your Kratom Is Still Good

When pulling your kratom out of storage, be careful to check for signs of deterioration. Things like mold, faded colors, and loss of scent all indicate that your kratom is no longer fresh, and will deliver disappointing effects if taken. 

Instead of settling for this stale kratom, we recommend picking up some fresh kratom for sale.

    Does old kratom not mix well with water? I found some I purchased to be clumpy and stay that way even after hot water and spoon stirring. Does Kratom give an ill effect after use when it’s old?

    • Jasmin Weber says:

      It is possible that the age of the kratom powder is causing it to clump up like that, although it could be a few other things like the humidity of where it was stored. From what we’ve heard, old kratom loses potency & becomes much less effective, but probably won’t have ill effects, although we can’t say that for certain as the way it’s been stored makes a difference.

  • K. Mark Smith says:

    Will it store well if it’s in capsules? Haven’t tried this yet but trying to stop using Suboxone. Any ideas

    • Jasmin Weber says:

      Hi there! Kratom does store very well in capsules, if kept in proper conditions (out of light & low humidity like a kitchen pantry) they should stay potent on the shelf for 3 months without issue, potentially up to 6 months. If the color is still vibrant & scent is not faded, your kratom probably hasn’t lost any potency. We wish you all the best in your endeavors, but because we aren’t doctors we cannot make any medical recommendations.

  • Shaun says:

    Hello everyone, was wondering how long Kratom resin and tincture last in the fridge or better yet freezer,thanks in advance

  • kendell clark says:

    I really like this article, I’ve always wondered about kratom storage. I store my capsules inside very large, 8k capsules each, tupperware containers with rubber lids with a vacuum seal, and the containers themselves appear to be light resistant, and on top of that, I store them in my desk cabinet, out of sight of light and oxygen. I always check one of the capsules I take by opening it, and the kratom is always potent and fresh. Seems that storing them in capsules protects them against some of this, and the containers do the rest. I’ve been taking kratom for over a year and I’ve never had a disappointing dose, I used it to get off of tramadol. I’m going to share this to my own timeline.

    • Jasmin Weber says:

      Wow, that sounds like a fantastic method of keeping your kratom fresh! The extra steps are absolutely worth it if it keeps the product perfect & ready-to-use!
      Thanks for sharing your method with us!

    • Matthew says:

      I also used kratom to get off tramadol! Of course, then I had to taper off kratom. It really is a helpful plant if used properly. Now I just use Javanica, which is surprisingly similar, but less potent. I arrived at this page look for methods of long-term storage because the leaves are so similar. Good luck Kendall, I hope you’re doing well.

      • kelly says:

        hi Matthew. my name is Kelly. I have a serious injury at the moment and stopped tramadol. does it actually help? help you sleep?

      • Ryan says:

        Now I want to get off Kratom, as I used it to get off methadone, but after a year free of the methadone, I’m having difficulty shaking the Kratom. I will try this…”javanica” stuff…never heard of it

        • Jasmin Weber says:

          We wish you all the best in your endeavors! Different methods work for different people, but tapering usage to smaller doses is perhaps a good place to start.
          All the best,
          GRH Team

    • James Proie says:

      Thanks Kendall just the answer I was looking for. I want to stock up. Also I prefer Kratom to medical marijuana. Kratom does not mess with my head and gets my lazy ass started for the day.

  • Ken Bodah says:

    I found some kratom in capsules in a travel bag I haven’t used in over a year. They were in a sandwich bag. Should I try them or throw them out?

    • Jasmin Weber says:

      Please understand this isn’t medical advice, only our best understanding of the subject- because kratom is a natural botanical and it’s possible for it to go stale or mold, we wouldn’t recommend using kratom that has been sitting that long if it has any visible signs of aging/discoloration.

  • Amber says:

    Can Kratom maintain potency after a couple years of storage or is it best to discard?

    • Jasmin Weber says:

      In our experience, kratom will definitely lose some potency after a couple years of being stored. If it’s been out of light, air, and hasn’t been exposed to liquid it might still be safe to use, but I wouldn’t expect very strong effects.

  • Amelia Hill says:

    Can you mix it with water and put it in the frigerator and use day by day and have it’s potent.

    • teelogas says:

      I have know reliable knowledge on this so take it as you want, my guess would be, that it’s not a good idea, since Kratom seems to like stable temperatures. So maybe having to let it thaw regularly is not very good.
      But as I said, just my 2 cents

    • Jasmin Weber says:

      Hi there, just mixing it with water, I’m not sure how that would go- but there is a way to make kratom tea very easily! You can find the recipe by searching kratom tea on the site!

  • Katie H. says:

    Does kratom lose some of iits potency after a meal ?

  • Jay Miv Dittmar says:

    Thanks,I will store it well.
