What Are the Strongest Kratom Capsules?

Strongest Kratom Capsules

With so many kratom capsule options to choose from, you might have a hard time picking the best for your needs. New users often start by looking for the strongest kratom capsules — but is there really such a thing, or is it a matter of personal preference?

The search for the strongest kratom capsules is complex, as there are so many variations, strains, and even sizes of capsules available. Ultimately, the “strongest” kratom capsule will depend on your preferences and the reasons you choose to use kratom.

Just like in our article on the strongest kratom strains, we’ll go in-depth on the most important factors for finding the suitable kratom capsules for your needs. Let’s jump right in with the most important points.

The Strongest Kratom Capsules: A Matter of Preference

Different users take kratom for different reasons, and different kratom strains are better suited to some purposes than others. Depending on your needs and why you take kratom, the “strongest” kratom capsules may differ for you than for others.

It’s all about choosing the right strain for your needs.

Kratom strains are typically classified in two ways: by strain color and by geographic region of origin. Both of these elements have an effect on the strains effects, and understanding each will help you find the strongest kratom capsules for your needs.

Strain Color: The Most Important Factor

When choosing the right kratom capsules, always start by choosing the right strain color. Besides choosing the right kratom vendor, it’s the single biggest factor for having a pleasant kratom experience.

Below you’ll find a quick run-down on the distinct effects of each strain. But if you’d like to learn more, be sure to check out our in-depth Guide to the Different Kratom Strains.

Red Vein Kratom: Calming, Relaxing

Most users looking for a calm, relaxing strain will end up favoring red vein kratom. Red vein strains are harvested very late in the kratom tree’s maturation cycle when the balance of kratom alkaloids has shifted towards higher levels of 7-hydroxymitragynine.

Red veins likely make for the strongest kratom capsules so long as you’re looking for a relaxing kratom experience.

White Vein Kratom: Energizing, Uplifting

Our users tell us that, for an uplifting daytime kratom, white vein kratom strains are the way to go. White vein strains are harvested at the earliest point in the kratom tree’s maturation cycle, preserving the highest proportion of mitragynine.

For those looking for a good “any time of day” strain of kratom, then white vein kratom strains are likely the strongest kratom capsules for you.

Green Vein Kratom: Balanced, Versatile

Green vein kratom strains are reputed to be a sort of “middle of the road”, offering a hybrid of red veins’ relaxation and green veins’ energy. Many Kratom Spot community members report using green veins for their versatility, as they are appropriate for use at almost any time of day.

Because they are jacks of all trades, most users will not find green vein strains to be the strongest kratom capsules, at least not for any particular purpose. But again: “strength” here is a bit of a misnomer, as we should be looking at how well suited the strain is to your purpose. And if you’re looking for a versatile strain? Well, green vein strains are the way to go!

Strain Region: A Secondary, But Meaningful, Factor

While the kratom leaves’ color has the biggest effect on which kratom capsules are right for you, the geographic origin of the strain is also worth considering. Due to variations in local environmental and agricultural conditions, different regional strains are subtly different from one another.

Again, these differences are far more subtle than strain color, so there’s no need to overthink this particular selection. Nonetheless, a basic awareness of these strains is great when you’re looking for the strongest kratom capsules.


Thai kratom is often associated with greater levels of energy, focus, and mood. Legend has it that it was these properties that made Thai kratom so popular among Thai manual laborers and other workers who had to manage excruciatingly long work days. But one thing’s for certain: Thai kratom strains are certainly a fan favorite, and they may be an excellent candidate for the title of “strongest kratom capsules.”

Borneo kratom is said to have a higher-than-usual mitragynine content. That’s the same alkaloid responsible for white vein kratom’s distinctive, purportedly energizing effects. So, it’s unsurprising: Borneo is a natural match with green vein kratom, and the combination is a strong candidate for the title of “strongest kratom capsules” — at least when it comes to uplifting morning use. If you prefer green or white strains but wish they were just a little more on the “up” side, then Borneo may be the strain for you.

Indo kratom is one of the most popular strains on the market, especially red vein Indo. These strains tend to be milder and more relaxing. Combined with reds, these definitely make for one of the strongest kratom capsules for relaxation. Combined with a green or white vein, they make a more balanced, mild, and relaxing experience than you’ll find with most other geographic varieties. Regardless of your pick, it’s easy to see why Indo strains of kratom are one of the Kratom Spot community’s favorites!

Malay strains of kratom are known for their versatility and their mild, balanced effects. Much as green vein kratom tends to combine the best of both red and white, Malay rides the center by providing a middle-of-the-road effect. And just like green vein strains, Malay kratom is unlikely to be the strongest kratom capsules for any particular purpose — but if you’re looking for a balanced, any-time-of-day strain, Malay is a great option.

Sumatra kratom is known as being somewhat more potent than many other regional strains. Some users compare it favorably with Maeng Da (described below). Whichever color strain you’re a fan of, expect a heightened experience when you shop Sumatra kratom. In short: Sumatra is certainly a contender for the strongest kratom capsules!

Maeng Da

Maeng Da is not actually named after a particular region, and Maeng Da strains of kratom come in all varieties. What these share is an unusually high potency! Indeed, Maeng Da literally translates to “pimp grade”, a cheeky reference to the top-shelf nature of these strains. Whatever color of Maeng Da kratom you choose, simply know that it will be a more potent experience than you’ll find from traditional strains!

Without doubt, Maeng Da strains make standout contenders for the title of “strongest kratom capsules”.

Like Maeng Da, Bentuangie kratom isn’t actually named after a region of origin. Instead, this describes a specific preparation of kratom. Red Indo kratom undergoes a special fermenting process, resulting in a strain of kratom leaves that is supposedly more relaxing and euphoric.
