Kratom
Our range consists of high-quality kratom sourced directly from Indonesia. Kratomuj.com was founded in 2026 to bring premium-quality kratom to customers across Europe, building on my experience in the kratom industry since 2017, when I launched my first project in the Czech Republic. We have worked with the same GMP-certified supplier in Indonesia since then, ensuring consistently high quality. Every batch is carefully selected, processed, and subjected to thorough laboratory testing.

Laboratory-tested kratom of the highest efficacy
We source Kratom solely from one exclusive supplier in Indonesia, with whom we have been working since 2017. The farmers involved in the collection and processing are members of the Appuri Association, which guarantees fair working conditions, but also the collection of the highest-quality leaves. For a long time, we have held the value of the active ingredient mitragynine at around 2%.
We detail all the information about kratom in our article “What is kratom?”
What is kratom and alkaloids?
Kratom (Mitragyna speciosa) is a tropical tree that grows mainly in Southeast Asia, especially in Indonesia, Thailand and Malaysia. Its leaves are rich in potent alkaloids, the most famous of which are mitragynine and 7-hydroxymitragynine.
Kratom contains approximately 0.5–2% alkaloids, where up to 69.4% of this is mitragynine, an alkaloid responsible for both stimulating and relaxing effects.

Kratom types – find the right one for you
Green kratom – most popular for its powerful and balanced stimulating effect. It improves mood and induces a sense of joy and euphoria, often serving as an alternative to alcohol.
White kratom – supports mental and physical performance and concentration. It helps with higher work or study loads, stimulates the mind and keeps your thinking clear.
Red kratom – soothes, relaxes and helps with pain relief. It has analgesic and aphrodisiac effects, reduces stress and supports quality sleep. In higher doses, it relieves pain and deepens relaxation.
Cultivation, harvesting and processing of kratom
Regular visits to Indonesia allow us to know in detail every step, from cultivation on fertile plantations to final packaging. The leaves are collected by hand and then dried in a controlled environment in the sun and in a greenhouse to maintain optimum alkaloid content.
Laboratory-tested kratom
Every batch of our kratom undergoes comprehensive laboratory testing in Indonesia, where it is analyzed for heavy metals, pesticides, microbiological contaminants, and alkaloid content. To ensure the highest standards of safety and quality, we also use gamma sterilization, which effectively eliminates microorganisms while preserving the product's natural properties.

Frequently Asked Questions
Everything You Need to Know About Kratom
How to Dose Kratom Safely?
Proper kratom dosage is key to safe use. Beginners should start with a low dose (e.g. around 1–1.5 g, or half a small teaspoon, with a maximum of one level small teaspoon) and gradually increase it as needed to test how their body responds. More experienced users typically use around 3–5 g per dose. The total daily dose should not exceed approximately 10–12 grams, as higher amounts increase the risk of unpleasant effects.
What Are the Side Effects of Kratom?
Kratom is a psychoactive plant, and therefore side effects may occur if it is used improperly or excessively. Users most commonly report nausea, stomach and digestive problems, dizziness, or headaches. Excessive and long-term use of kratom may put strain on the liver and kidneys. Risks can be reduced by choosing high-quality, laboratory-tested kratom and taking an overall responsible approach without combining it with alcohol or certain medications.
Kratom and Driving?
We do not recommend using kratom before or while driving a vehicle. Kratom may affect attention, reaction time, and coordination. Although there is currently no explicit rule stating that driving under the influence of kratom is prohibited, its effects on the body should be taken into account. Kratom yes, but never behind the wheel or while operating machinery.
What Does Kratom Do in the Body?
Kratom contains alkaloids, primarily mitragynine and 7-hydroxymitragynine, which act on receptors in the brain and nervous system. Depending on the type of kratom (white, green, red, yellow), the amount, and individual sensitivity, users may experience increased energy and focus, improved mood and sociability, or, conversely, greater relaxation and pain relief.
What Is Kratom Used For?
Users primarily seek it out for its subjectively perceived effects on mood, energy, focus, or, conversely, relaxation, calming effects, and pain relief. Effects may vary depending on the type of kratom and individual sensitivity. Kratom is not a substitute for professional medical treatment, and its use is always at the user's own responsibility.
Is Kratom Safe?
Kratom is not completely risk-free; its safety depends mainly on the frequency of use, the amount, the quality of the kratom, and the user's health condition. Long-term daily use in high doses and combining kratom with alcohol, sedatives, or certain medications can be considered particularly risky.
Is Kratom Addictive or Does It Cause Withdrawal Symptoms?
Long-term and frequent use of kratom may lead to dependence. Some users report withdrawal symptoms such as irritability, poor sleep, muscle pain, digestive problems, or a strong urge to take kratom again. The risk of dependence can be reduced by not using kratom every day, taking breaks, and monitoring your body's and mind's response. Kratom may only be sold to and used by persons over the age of 18 under current legislation.
What Is the Difference Between White, Green, and Red Kratom?
The main difference between white, green, and red kratom is related to the drying process, fermentation and processing of the leaves, which affects the alkaloid profile and the resulting effects. White kratom is perceived as the most stimulating and is mainly used to increase energy and focus. Green kratom combines mild stimulation with light relaxation and a more pronounced effect on positive mood, for example as an alternative to alcohol. Red kratom tends to have a more calming and relaxing effect and is often associated with deeper relaxation and pain relief.
How Long Do the Effects of Kratom Last?
The effects of kratom may begin within a few tens of minutes and last for several hours. The duration of the effects is individual and varies depending on the type of kratom, the amount, and individual sensitivity. In general, the effects are described as lasting approximately several hours and gradually wearing off. Kratom is a psychoactive substance and, under the law, may only be sold to and used by adults (18+).
Can Kratom Be Combined With Alcohol or Energy Drinks?
Combining kratom with alcohol or energy drinks is not recommended, as it may significantly increase the strain on the liver and heart. Alcohol may intensify nausea and loss of control, while combining kratom with energy drinks or high doses of caffeine may lead to heart palpitations and overstimulation of the system.
What Is the Difference Between More Expensive and Cheaper Kratom?
Today, kratom may only be sold by a licensed seller, and basic safety requirements should be met by everyone who sells kratom. However, the price may vary depending on the quality of the leaves and the production and processing methods. More expensive kratom usually undergoes more careful leaf selection, better processing technology, and more detailed laboratory testing, resulting in more consistent effects.
