Kratom and kava have both become increasingly popular in the western world. On the surface, they seem to have a lot in common. Both substances come from plants. They’re often sold alongside each other, and are often used to relieve anxiety. This may lead you to the question of whether you should try kratom or kava.

Both kratom and kava carry benefits and risks. We’ll touch on them here, but for a deeper dive on some of these specific properties, check out these articles on kratom for sleep and kratom for energy.

Despite the surface-level similarities, they’re entirely different substances with completely different psychoactive processes. Before consuming either, it’s important to have a baseline understanding of not only their effects, but their mechanisms for effect. As we all (hopefully) learned in high school biology, form follows function, and that holds true here as well.

Here are the factors that make kratom and kava very different from each other, and the steps you should take before consuming either.

Different Plants

Kava piper methysticum
kratom plant
Kratom mitragyna speciosa

Kratom and Kava are similar in that they’re both naturally-occurring substances extracted from plants with very different evolutionary backgrounds.

Kratom comes from a tree called mitragyna speciosa native to Southeast Asia. The tree is a cousin of coffee plants.

Kava comes from the plant piper methysticum, which is indigenous to the Western Pacific, like Hawaii and other islands. This plant belongs to the pepper family.

Since they’re not even closely-related species, their properties will also be very different. Historically we can look at how they were used among the populations indigenous to where they grow. In Thailand where Kratom grows, they chewed the leaves of the kratom tree to

Similar Effects, Different Mechanisms

kratom vs kava

Both plants can relieve stress, anxiety, and even support sleep and insomnia in several instances. However they do so with completely different mechanisms.

Kava’s Mechanism

Kava contains a class of compounds called kavalactones which act on the gamaminoburtyic-acid (GABA) receptors. GABA is notoriously linked to sleep and relaxation, which makes kava a clear depressant. This mechanism also makes perfect sense why kava reduces anxiety. This makes kava’s main use as a substitute for alcohol in social situations. Both compounds are classified as depressants.

Kratom’s Mechanism

Kratom contains two alkaloids, mitragynine and 7-hydroxymitragynine (7-HMG), which act on the same receptors as other psychoactive compounds like opioids. Because these serious painkiller drugs act on these receptors, they’re called the opioid receptors. As you can imagine, this explains a lot of the controversy with kratom. But it also explains one of the more potentially beneficial use cases, and that’s its use in opioid withdrawal.

At modest doses, this reaction in the brain provides a stimulating effect like its cousin, coffee, and pain-relief effects. At higher doses, it can support sleep as well, a controversial claim which we explore in greater depth here.

Green Kratom Strains for a Similar Effect

If you want the mix of alertness and euphoria but with a relaxant effect, which is as close to kava as you’re going to get, then use green strains of kratom. Green strains are a mix of red and white, which have differrent alkaloid compounds. Generally, red is less stimulating than white, so green gives a mix of both.

As we’ll talk about later, you should only get kratom from a trusted source. So if you want to try kratom for this effect, Viable Solution’s Green Maeng Da is a safe place to start.

Different Effects

Sure, kava and kratom can have similar effects, but they have many differences as well which stem from the different mechanisms.

First, because kratom acts on the opioid receptors, it has the potential to support opioid withdrawal. It also clearly has a pain relief effect which kava lacks. So if you’re looking for either of those two benefits, kratom is the way to go.

Second, kratom can be a sedative at high doses of certain strains, but in general, it has a stimulant effect. We can go back to its indigenous uses to see this and it’s backed by countless anecdotal evidence from the 5 million plus kratom users in the US alone.

While there are similarities, these are completely different substances with very different effects.

Different Use Cases

Because they’re different, they’re used differently too.

How Kava is Used

Kava traditionally was used before ceremonies as a way to bring people together. Today it’s used as a social drink at bars (kava bars, where they don’t sell alcohol). It’s used to relax and relieve anxiety.

Many report it as a replacement to alcohol, which means it may have some merit to supporting alcoholics, although as of now there isn’t any research behind this.

How Kratom is Used

Kratom isn’t used as much in social situations, and is more for pain relief, as a stimulant, or at higher doses as a sedative. It also, as we’ve mentioned, has potential for opioid withdrawal.

In other words, entirely different uses.

Risks of Kratom vs Kava

Addictive Potential

Like almost any substance, from everything from caffeine to alcohol, both kratom and kava have addictive potential. Anybody who tells you one of them isn’t, is almost definitely trying to sell one of them to you. (I’m talking to the kava sellers in particular, who love to claim that kava isn’t addictive.)

The addictive potential of kratom is stronger and more recognized. If you generally have a problem with moderation and addiction, it might not be the best choice for you to either get that energy boost, help relieve pain, or improve your sleep. But in moderation, like almost anything, can have remarkably beneficial effects and is perfectly safe. Many users anecdotally claim that as long as you don’t go above 5g per day of kratom, you won’t have anything more than minor side effects.

Often kava is claimed as non-addictive. This is simply not true. Like I said, they’re trying to sell you kava. Kavalactones also act on receptors that signal the release of dopamine, leading to a euphoric experience like we feel with other drugs, like alcohol. Anything that releases dopamine part of us will want more and more of. That said, the addictive potential is likely much lower than that of kratom. However, keep this in mind when using kava.

Health Problems

Kratom used frequently at high doses can cause nausea, sweating, and other common withdrawal symptoms. We won’t dive in too much, but if you take kratom ALL THE TIME, that’s inadvisable. If you take alcohol all the time too, that’s inadvisable. There are almost no total panacea substances you can take without care. And the ones that are unequivocally safe, like fish oil, generally won’t have as strong an effect.

Kava’s main reported health effect is liver damage. It’s kind of funny, that like alcohol, kava can damage the liver. Again in moderation it’s probably nothing to worry about, but do not abuse kava.


Kratom is legal in the US, but is not FDA approved so it’s not subject to strict, safe manufacturing processes. This means that kratom you buy in stores and online, may be contaminated and complete garbage.

This is crucial when selecting kratom. You should ONLY buy kratom from places with transparent manufacturing and third-party approval. To that, Viable Kratom has the strictest and most transparent processes in the industry, so if you do give kratom a shot, keep it simple for yourself and get it from them. DO NOT buy kratom from your local gas station or smoke shop. You’ll have no way of knowing what you’re getting.

Kava is legal and available at places like “kava bars.” Not only is it legal, but it’s classified as a dietary supplement by the FDA, and therefore is subject to many of its regulations. This is generally positive because it means Kava in the US is less likely to be contaminated or otherwise made with shady practices. Keep in mind, though, that supplements still have limited regulation, and supplement companies can get away with a lot. Like kratom, you should still seek out kava sources that are third-party tested.

Can You Take Kratom and Kava Together?

There is no research on combining the two, but it seems like it’s not necessary. Although there are products on the market right now that combine them, taking a stimulant (kratom) and a depressant (kava) on the surface seems counterproductive. I would try one based on your specific circumstance if you’re trying to reduce anxiety and see for yourself how it helps you.

These are substances with a lot of potential and are both worth exploring, but they carry risks. Like a good scientist, do your best to isolate variables and start by trying them separately if you think they can support you.

Kratom and Kava In Conclusion

While kratom and kava share some surface-level similarities and are often used for similar purposes, they are different substances.

Kratom, derived from the leaves of the mitragyna speciosa tree native to Southeast Asia, contains alkaloids that act on opioid receptors, potentially providing pain relief and aiding in opioid withdrawal.

On the other hand, kava, extracted from the roots of the piper methysticum plant indigenous to the Western Pacific, contains kavalactones that interact with GABA receptors, inducing relaxation and anxiety relief.

Both substances have their own set of risks, including potential health problems and regulatory issues.

Whether to try kratom or kava depends on your preference and desired outcome. Be sure to always start with a small dose, and book a consult with your doctor if you are unsure about your usage.
