5 Best Kratom Capsules in 2023

Kratom is the latest superfood that’s taking the plant-based wellness world by storm. Kratom leaves contain a powerful, all-natural phytochemical called mitragynine that acts on the nervous system by bonding to opioid receptors.

Obviously, this potentially makes Kratom a great alternative to opioids.

Like cannabis before it, Kratom is now gaining more steam for its litany of natural benefits. People looking for plant-based wellness to help with sleep, anxiety, pain and more are experiencing relief with Kratom. 

You can take Kratom a few different ways:

  • Capsule form: Kratom capsules contain Kratom powder and (sometimes) additional ingredients like fillers or superfood powders.
  • Powdered form: You can use Kratom powder to make tea or to add to a smoothie.
  • Extract form: Kratom extracts are a more concentrated form of Kratom powder that allows users to take a small amount for a more potent effect.
  • Kratom leaves: For Kratom purists and those who want to take Kratom the old-school way, you can use the leaves to make teas and elixirs. 

Our two cents?

Kratom capsules are one of the easiest, most popular ways to get down with this wonder plant from Southeast Asia. 

They’re perfect for travel, for throwing in your gym bag, you get the idea. 

But here’s the thing — 

Kratom is still a relatively new supplement, which means there’s a lot of inferior products out there. Some of which could even be dangerous, like in this FDA probe that revealed toxic levels of heavy metals in imported Kratom. 

The main thing to look out for is transparency. 

Kratom companies that disclose their sources in Asia, their processing, and their lab testing protocols are the ones you want to buy from. (Don’t go for the nondescript bag of Kratom powder at your local head shop.)

So naturally, what did we do?

We reviewed the most popular Kratom companies in the US and selected a handful of reputable Kratom vendors in our search for the best Kratom capsules to make it easy to buy Kratom online. 

Here are the best Kratom capsules available this year. We’ve covered a nice variety of different strains and blends, all from transparent brands with safety and testing protocols in place. There are also different effects from different Kratom strains on our list. Some are energy boosters while others are for relaxation. 

Check out our review complete with descriptions of the effects of each, what users say about taking them, ingredients and more.

Benefits of Using Kratom

Kratom is a relatively new superfood on the market and has gained a reputation in the plant-based wellness world as the next best thing.

But what’s behind all the hype? Can Kratom really help make people feel better inside and out? The anecdotal evidence of countless verified Kratom users points to yes

There’s also a documented history of Kratom use in Indonesia that goes back hundreds of years to support its effectiveness. 

People in Southeast Asia have traditionally chewed kratom leaves or made them into tea. Kratom has been commonly used to treat fatigue, diarrhea, and pain in the area. The plant’s leaves have also been used ritualistically in local religious ceremonies.

Fast forward to today, and people all over the globe are taking kratom as an alternative to traditional medicine. In this interesting survey by Johns Hopkins of nearly 3,000 adult kratom users, the majority take kratom to deal with pain, anxiety and depression.

However, note that the FDA has not approved the use of kratom for any kind of medical treatment. 

Adding kratom to your daily health regimen may help you get a leg-up on your wellbeing. Here are the natural benefits of taking kratom:

Energy boost

Kratom is known to have stimulant-like effects, and most users report an energetic feel in lower doses. For energy, green kratom, yellow kratom, and white kratom strains are most popular.

Anti-inflammatory/pain relief

The main alkaloids present in kratom– mitragynine and 7-hydroxymitragynine– may relieve pain by binding to opioid receptors. This makes kratom a natural opioid with analgesic and pain-relieving properties.


A lot of people claim to get their anxiety under control by turning to kratom, but this evidence is pretty much all anecdotal. However, here is a recent, legitimate case study of kratom use in self-regulated treatment of anxiety and depression. The findings are positive and indicate that kratom could have potential to help symptoms of anxiety. 

Better sleep

Kratom is also used commonly to get a good night’s rest, and users report being able to fall asleep and stay asleep faster. Kratom users looking for better sleep most commonly take their capsules at night, allowing for around 30 minutes to absorb through the digestive tract. Red kratom strains are most widely taken for those who want the plant’s more relaxing effects to come through.

Digestive health

While further research is needed, remember that kratom leaves have been used for centuries in Southeast Asia to treat diarrhea. Research on rats shows that mitragynine from kratom may help relax the digestive system and reduce acidic buildup that can cause gastrointestinal problems.

The Best Kratom Capsules in 2023

These are some of our favorite kratom vendors and products so that you can buy kratom online and know that you’re getting the best options available.


K-Tropix 2K ENERGY Capsules

1. K-Tropix 2K ENERGY Capsules

A lot of hard-working people end up landing on kratom capsules because they need more energy, without the pitfalls of a coffee addiction. People want natural, plant-based energy without the mal effects that come from chugging energy drinks all day.

Our #1 pick for energy-boosting kratom capsules goes to K-Tropix. They’ve taken the natural energy we love from kratom and made it even smoother. 

These little supplements are powerful, all-natural, and contain brain-healthy compounds that make the effect like no other. 

That’s because K-Tropix is into the science of natural nootropics- compounds that can help boost brain function. One of these is caffeine, and K-Tropix puts 100mg in each capsule to add a powerful energy charge.

The next brain booster is K-Tropix’s unique blend of teacrine and dynamine. According to the brand, these nootropics have been found to have therapeutic effects for both anxiety and caffeine withdrawal aka the jitters. 

The combination of caffeine and other nootropics with kratom is a somewhat new undertaking. K-Tropix’s innovation in this area is helping people get energy they need from scientifically researched ingredients. No crash, no anxiety, just the brain boosters you need to think and feel great all day. 

What we love: 

  • Super-potent energy boost
  • No crash
  • Brain-healthy ingredients

K-Tropix kratom capsules are hands down, effective. Kratom combines with natural caffeine sources to give you that all-day energy that doesn’t make you feel like crap at 3pm. We also happen to recommend at 3pm to beat the afternoon slump and get your workout in with a smile:)

Each capsule contains:

  • 100mg mitragynine (kratom powder)
  • 100mg caffeine
  • 100mg proprietary nootropic blend

Recommended use: 1 capsule for hours of energy

Effect: Powerful energy boost, focus, long-lasting energy

What users say: The online reviews for the 2K energy capsules are all nearly identical when it comes to describing potency. Reviewers consistently touch on the huge energy boost they feel with just one capsule and how they don’t experience jitters. We saw that people who work at night or at multiple jobs, especially, are big fans.


MIT45 Red Vein Capsules

2. MIT45 Red Vein Capsules

Like hemp and other superfoods, kratom provides a variety of natural benefits. Our #1 pick showcases kratom’s energetic effects, but coming in hot at #2 are MIT45’s game-changing red vein kratom capsules. If it’s stress relief or better sleep you’re after, this is the place.

Red vein kratom looks different from traditional green kratom. Its leaves have pronounced red veins. This kratom strain also receives more sun exposure than the other kratom varieties, as it’s more mature at the time of harvest.

Red vein kratom contains mitragynine, the principal alkaloid found in the kratom leaf. It also contains a high concentration of another phytochemical known as 7-hydroxymitragynine. This high concentration gives red vein kratom more relaxing and pain-relieving effects.

MIT45’s red vein kratom capsules are powerful and fast-acting. We love that MIT45 takes testing seriously, and third-party lab reports are available for every single kratom supplement they sell. 

Included in MIT45’s kratom testing are results for microbials, heavy metals, yeast, mold, and more. To see the results for your product, simply enter the lot number on MIT45’s website to see an up-to-date Certificate of Analysis. 

What we love:

  • Pure, red vein kratom powder 
  • Highest standards for lab testing
  • All-natural relaxation and stress relief

While certain kratom strains are known for their energy-boosting effects, red vein kratom is a more calming variety. In low doses, it feels like it calms the nervous system. We can see red vein kratom potentially in a wide range of applications, from sleep health to pain management.

Each capsule contains:

  • 0.5 grams red vein kratom powder

Recommended use: 1 to 2 capsules taken in the evening/night

Effect: Anti-inflammatory, calming, sleepy

What users say: Users who choose red vein kratom many times are looking for help with pain and sleeping. Everyone is different, so it’s best to start with just 1 of these kratom capsules until you know how your body will respond. The majority of users say 1 or 2 capsules helps them have a deeply restful sleep, and most take them at night.


Just Kratom Trainwreck Kratom Capsules

3. Just Kratom Trainwreck Kratom Capsules

The best multi-strain kratom we’ve found are the trainwreck capsules from Just Kratom. Just Kratom blends their high-quality strains of red, green, and white to support balance and overall wellness. 

Red kratom strains are known for their more sedative effects, usually taken to promote sleep, relaxation, anti-inflammatory relief, etc. Then you have green kratom, sought after for its energy without the crash. And last, white kratom is largely used to support good mood and concentration.

The energetic effect from these three strains together is one of balance. In fact, we recommend the trainwreck capsules for regular users who can experience the benefits of microdosing each of these kratom strains.

Also, you can buy Just Kratom’s kratom capsules starting at a 30-count all the way up to 1000 capsules per bag. This is a great product if you want to limit the psychoactive effects of kratom while experiencing the natural wellness benefits. 

Just 1 to 3 per day along with your supplements may just deliver that extra boost you need to conquer the day. You can take these kratom capsules at any time and keep kratom in your system on a daily basis. 

What we love:

  • Red, green, and white kratom 
  • Take anytime
  • Great value for regular kratom users

The best part about Just Kratom’s trainwreck capsules is that they bring you a low dose of the benefits of each kratom strain. The result is a boon to overall wellbeing– think long-lasting energy, good sleep, and a feeling of balance.

Each capsule contains:

  • 0.5 grams red, green, and white kratom powder

Recommended use: 1-3 capsules per day

Effect: Good mood, calm energy, overall wellbeing

What users say: Unlike specific kratom strains that you’d flock to to tackle an issue — i.e. taking red kratom for stress relief — the trainwreck capsules are more holistic in nature. Rather than high doses of one strain, they deliver microdoses of each. This makes the effects less psychoactive and more subtle. You can take the trainwreck capsules at any time, without disrupting your sleep or energy (at low doses).

4. Kingdom Kratom Capsules Small Sample Pack

What we love:

  • Select 4 different kratom strains

  • Lots of positive verified reviews

Different kratom strains have different effects, and everyone’s system is unique, meaning that what’s right for one person may not translate to someone else. This is why Kingdom Kratom’s sampler pack is so awesome: you can try the different types of kratom to see how they will affect you. This is a great entry point into using kratom as a natural alternative. 

Each capsule contains:

  • 550mg kratom powder of your selection: green, red, white, yellow, and multi-strain blends

Recommended use: 1-3 capsules per day

Effect: Because Kingdom Kratom offers such a wide selection of kratom strains, we can’t list all the possible effects here. Luckily, the brand offers this useful kratom guidebook that details the description and effects of each strain they offer. Take a look before selecting your strains in the sample pack. That way, you’ll have a better idea of what you’re in for with each variety.

What users say: The reviews for Kingdom Kratom’s sampler pack are currently all 5 of 5 stars, with only 1 errant reviewer giving it 4 stars. Repeatedly, we notice that people rave about the sampler pack because it helps them land on their favorite strains. Users try different blends at different times of the day, and households with more than one kratom user are also big fans.

Each capsule contains:

Recommended use: 1-3 capsules per day

Effect: Calm, energetic, good mood

What users say: It appears most users report that these white kratom capsules aid with stress relief and cognitive support. Unlike green kratom, white kratom doesn’t provide a huge energy boost.

How We Chose Our Winners

There are more and more kratom companies popping up on the internet, so it can be hard to know who to trust, especially if you’re new to kratom. That’s why we kept in mind the following qualifications to make our list:


Where does the kratom come from? How is it processed? These are important questions that every kratom supplier should be able to answer. All the kratom capsule brands on our list show high levels of transparency by disclosing the geographic location of their sourcing. Additionally, kratom brands should be able to speak to how their imports are processed and what kind of specifications they must meet.

Lab Testing

Not to get too scary, but you should know that there have been some ugly outbreaks and toxic materials found in imported kratom in the US. To avoid inferior quality and unsafe supplements, make sure that the kratom capsules you purchase come with a lab test to back them up. All the kratom brands on our list provide current, independent lab reports for their kratom capsules. These reports show negative results for contaminants like mold, yeast, and heavy metals. 


Will it work? Whenever you buy a new dietary supplement, it can feel like you’re rolling the dice. Therefore, we wanted to make sure our favorite kratom capsules pass the efficiency test: not only with us, but with verified users online. We went through the reviews for each product to make sure users reported that the capsules were indeed effective and provided value for the money.

What is Kratom?

Kratom — official scientific name, Mitragyna speciosa — is a tree indigenous to Southeast Asia, specifically southern Thailand and the northern Malay Peninsula. Its leaves are sold

commercially around the world to people looking for alternative, plant-based medicine.

  • Kratom leaves are used to make tea or are ground up into kratom powder to make kratom capsules. 
  • The major phytochemical at play in kratom is called mitragynine, an alkaloid that binds to the body’s opioid receptors.
  • Because kratom binds to opioid receptors, it’s commonly used for issues like pain, anxiety, fatigue, stress and sleep problems. 

Potential Side Effects of Using Kratom

According to integrative medicine specialist Yufang Lin, MD, kratom has the following potential side effects

  • Psychoactivity
  • Constipation
  • Drowsiness
  • Dry mouth
  • Nausea

As always, consult your healthcare practitioner when beginning any new health regimen.

How to Store Kratom Capsules

You should store your kratom capsules like you would any dietary supplement: in a secure, dry place at room temperature. 

The biggest thing to avoid is moisture and any changes in humidity, as this can affect the quality of the kratom capsules and potentially cause mold.

If you live in a tropical, super-humid environment, store your kratom capsules in the refrigerator to avoid moisture and high temperatures. 

Kratom Frequently Asked Questions

What are the different Kratom strains and effects of each?

Different kratom strains have different effects. Here’s a quick run-down:
Green kratom: Energy and focus
Red kratom: Sleep, pain relief, and relaxation
White kratom: Mood and sustained energy
Yellow kratom: Energy and clarity
Multi-strain blends: Combinations of the above effects

Is Kratom the same as CBD?

No, kratom is not the same thing as CBD. Kratom comes from a specific kratom plant, aka from a tree indigenous to just one geographic area; it’s a totally different plant than CBD, which comes from cannabis sativa aka the hemp plant.

Can I take Kratom every day?

You can take kratom every day, provided you do not experience any adverse side effects. Remember, always consult your physician before starting a new health regimen.

Will Kratom make me high?

Kratom has documented psychoactive properties, but it depends on how much you take. Kratom in lower doses is not as strongly associated with psychoactivity. In higher amounts, kratom may cause a feeling of euphoria and/or sedation. 

Final Verdict

We love all the plant-based goodness kratom capsules have to offer. Our favorite benefits of kratom include energy, anti-anxiety, sleep health, digestive health, and more. Although most of the evidence to support kratom’s benefits is anecdotal, we also found a lot of scientific research into mitragynine, the alkaloid found in kratom that binds to opioid receptors.

There are a ton of kratom capsules to choose from, but we selected the top 5 of 2023 that meet our standards for transparency, safety, and efficiency. These include the best kratom capsules for energy, the best for sleep, the best multi-strain blend, the best for beginners, and finally, the best white kratom. 

The best kratom capsules for you depend largely on your wellness concern and desired effects. Each of our selections provides a different effect but is backed by current lab reports for safety. So whether you’re looking for pain relief, more sleep, or more energy, kratom capsules have your back!
