How Long Does Kratom Take to Kick In?

Kratom is a commonly used name for the Mitragyna Speciosa tree. This tropical member of the coffee plant family is grown in Southeast Asia and has been used by workers for hundreds of years to boost focus and productivity or, in larger doses, as a sedative and pain reliever. 

Kratom has become popular outside of Southeast Asia in recent years, and many people around the world are now trying kratom as a natural plant-based aid to daily life. As it can come in capsules, powder, tincture, or natural leaf form, there is some uncertainty about how long the effects kick in and how long they last. 

The main alkaloids in kratom that are responsible for its effects are mitragynine and 7-hydroxymitragynine. These compounds need to interact with the opioid receptors in the brain to produce either an energizing and focus-boosting effect or a calming effect. 

In this article, we will answer the following questions:

How long does kratom powder take to kick in?

Powder is the most common and readily available form of Kratom in the U.S. Powder can take 10-15 minutes for the effects to start kicking in. Depending on the dosage, the effects can last 2-8 hours. Doses of around 4-5 g usually last around 2 hours. Doses of 7-8 g can last up to 8 hours, with the peak effects reportedly felt at the 1.5-2.5 hour mark. While most doses are around 4-8 g, it’s important to note the effect will be different for everyone. 

How long do kratom capsules take to kick in? 

Kratom capsules take slightly longer to kick in because the stomach needs to digest the capsule shell. If capsules are of good quality, they will be made from easily digestible substances. There are two main capsule types: cellulose-based and gelatin capsules. 

The former are vegan and easy to digest, while the latter are not vegan but also easy to digest and are the most common type of capsule available. 

Capsule shells take about 15 minutes to dissolve. The effect of Kratom capsules can be felt between 25 and 45 minutes after taking them. Their effects last as long as for powder because they are powder put into a capsule form. 

How long does kratom tincture take to kick in?

Kratom tinctures are the most potent form of kratom as they are concentrated extracts. You can take Kratom tinctures mixed in food or drink or swallow them directly. They can come in extract shots, which is an easy way to take them. 

Kratom tinctures usually take about 5-10 minutes to kick in, and their duration depends on the dosage you take. A good idea is to start with small dosages and work your way up. This way, you won’t find yourself inadvertently sedated for 8 hours. 

What factors affect kratom absorption?

The factors that affect kratom absorption are: 

Fullness/emptiness of the stomach 

The fullness of your stomach affects the rate at which kratom is absorbed. If you have just eaten, it will take longer for your stomach to digest the kratom as it must first digest the food. Taking kratom on a full stomach can also lead to nausea. On the other hand, a full stomach can sometimes extend the effects of kratom but make them milder as your body digests the kratom alongside the food. 

Taking kratom on an empty stomach can cause nausea, too. We recommend taking Kratom 2-3 hours after your meal so your stomach is not empty but doesn’t have much food left in it. 

It may take longer for older people to feel the effects of kratom as the body’s processes naturally slow down with age, which makes digestion take longer. 

Body fat 

One of the alkaloids in kratom, mitragynine, is highly fat-soluble, so someone with a more significant amount of body fat may absorb kratom more quickly and feel more potent effects. 

Metabolic rate 

If you have a high metabolic rate, meaning your bodily processes move faster, your kratom effects might come on faster. 


If you take kratom regularly and have developed a tolerance for it, it may take longer for the onset of effects, and you may require a higher dosage. 

Water intake 

If you drink too much water, you can dilute the kratom and move it through your body too quickly, but if you drink too little, you could become dehydrated. Kratom is also a diuretic, which means it can dehydrate you if you don’t drink water. The best route is to take the kratom with water and keep drinking small amounts throughout the period in which you are feeling the effects. 

What can you do to speed up kratom absorption? 

Some people like to potentiate or enhance the effectiveness of kratom by taking it with another product or by using the red bubble technique. We advise you to be very careful when doing this because adding other substances to kratom could cause the alkaloids to act unpredictably. 

There are two reasons to use a potentiate: to prolong the effects of kratom while taking less of it or to increase the effects without taking more kratom if you have developed a tolerance for it. 

Citrus juices, such as orange, grapefruit, lime, and lemon juices, act as potentiators because their enzymes help to activate the alkaloids in kratom.


The onset of kratom’s effects depends on the form in which you take it and the state of your body at the time. The duration depends on how much you take and your tolerance for kratom.
