How Long Does Kava Last

How Long Does Kava Last?

Kava is a traditional beverage that originates from the South Pacific Islands. It has been used there for centuries as a recreational drink and medicine, and can be taken in pill form or as kava tea. 

Kava is sometimes called “the most effective anti-anxiety agent on Earth.” In this article, we will answer the question “how long does kava last?”!

How Long Does It Take for Kava to Work?

In short, it all depends on how you take it. If you drink kava, the effects will be felt within minutes as the kavalactones are absorbed into your bloodstream directly through your gut. However, if you take kava in pill form, it can take up to an hour for the active ingredients to be released for absorption by your body.

The effects of kava usually peak around 45 minutes after ingestion and last for two to four hours. After this initial period, there is a gradual decline in the effects experienced until they disappear entirely 12 hours later. So, if you’re planning on drinking kava for treatment of anxiety, make sure you allow enough time for it to kick in and plan accordingly!

There are many different kava experiences, so how long the kava you ingest lasts will also depend on how much is consumed. If you take too little, the effects might not be felt at all, or could even be slightly negative in that it will intensify your anxiety rather than alleviate it. 

At moderate doses of around 200 – 400 mg worth of root extract (or 70 – 140 grams when made into tea), people often experience feelings of calmness and tranquillity without mental cloudiness or impairment. Kava can also help ease muscle tension and pain if taken in a larger amount.

What Happens in Your Body Immediately After Drinking Kava?

When you drink kava, it begins to take effect within 30 minutes and can last for up to 90 minutes. The micronized kavalactones begin to bind with GABA receptors as soon as those micronized particles hit the stomach lining. This reduces stress hormones such as cortisol and adrenaline after just 25 – 30 minutes of drinking or otherwise consuming some form of Kava beverage or extract.

However, not all effects will occur immediately. Instant versions generally have a more rapid onset than traditional brews since they’re made from already extracted material that has been dried into powder form, which means they are ready for micronization.

Consuming up to 250 mg of micronized beverage extract is an optimal dose for aiding in relaxation. This 250 mg limit is ideal because it won’t cause cognitive dulling or sedative effects that may lead to a lack of focus. In studies conducted on kava used as a treatment for anxiety, it was found that the dosage required ranged from 120 – 240 milligrams per day, with subjects reporting significant relief within one week.

The best results were reported after two weeks, which led researchers to conclude that staying on this regimen for anywhere from three to six months would be necessary in order to properly assess each individual’s needs.

As we were saying, the micronized particles cross the blood-brain barrier and bind with GABA receptors, reducing stress hormones such as cortisol and adrenaline. This results in an increased sense of well-being for up to six hours after drinking kava beverages or taking it in other forms like powders or capsules/pills before bedtime. 

If you’re trying instant versions, be sure that they do not contain extra ingredients besides micronized material because this will allow you to experience the best effects! Otherwise, adding maltodextrin can reduce its potency due to negative interactions between these two substances when mixed. So, if you want the full benefits, micronized kava is the way to go!

Factors that Can Affect Kava and Your Body

Several factors can influence the effectiveness of kava. Some include: Kavalactone content, other ingredients in your cup, and whether the powder is micronized or non-micronized. Another factor to think about when ingesting kava root products is whether or not it was prepared using a traditional method. 

Since there are so many ways to prepare kava drinks, some methods produce substances that may require more time than others to notice an effect depending on multiple variables which we discuss below!

Kavalactone Content

The potency of kava will vary depending on its source and how it was processed. The effectiveness of kava is usually determined by the kavalactone content, which is the main active ingredient in the plant. This means that a higher-quality product with more kavalactones is likely to be more potent than a lower-quality one.

The kavalactones are the main active ingredients in the plant, so a higher-quality product with more of these is likely to be more potent. It’s also important to know that kavalactones aren’t the only thing that matters when it comes to effectiveness. Other ingredients in the drink, such as water and herbs, can also play a role.

Other Ingredients in Your Cup

If you’re mixing kava with other ingredients like fruit or water, the amount of time it takes for your system to absorb it may be delayed or sped up. For example, drinking juice and kava can help absorb it faster because of the added sugar. Conversely, adding milk to your drink can slow down absorption. 

The effectiveness of kava can also depend on the other ingredients in your cup or drink. This is due to the fact that, as you consume kava, it can cause side effects for those who are sensitive to other ingredients such as caffeine. This means that the effectiveness of kava can be reduced by these additional ingredients even if you don’t suffer from any caffeine-induced feelings of anxiety or restlessness.

Micronized or Non-Micronized Powder

Kava roots come in different particle sizes. Micronized kava is ground into very fine particles, while non-micronized kava contains whole or chopped-up pieces of the plant. 

It’s also important to note that kava effectiveness and onset times will be influenced by how you prepare your drink. For example, some people prefer mixing their drinks with more liquid than others due to preference or because they don’t want it too strong.

Traditional Preparation vs Pure Extract

As we mentioned before, the traditional way of preparing kava can cause the amount of time it takes for you to notice an effect to be higher than if you’re using a pure extract from an ethanolic extraction process. This is because other ingredients in the drink can slow down or delay absorption. 

Metabolism and Reverse Tolerance

Kava’s effects will also depend on your body’s metabolism. This means that if you have a slower metabolism, kava products may take longer to kick in than for someone with a faster metabolism.

Reverse tolerance can also determine the effectiveness of kava for different individuals. This means the more you drink, the less effective it will become for you to achieve its effects because of how tolerant or resistant your system becomes to it over time.

Strength of the Individual Dose

Another factor that affects effectiveness and onset times is the amount of kava used per cup. For example, if someone drinks a potent kava beverage, this could make effectiveness slower than someone who’s drinking a weaker one even though they’ve consumed similar amounts due to their different concentrations or preparations.

Taking all these variables into account when consuming Kava root beverages means there’s no one-size-fits-all approach to determining effectiveness and absorption time!

Benefits of Kava

Kava is a dietary supplement that has many benefits. These benefits include reducing anxiety, relieving stress, and promoting relaxation. Kava can also be helpful for people who have insomnia or other sleep disorders.

Natural Alternative to Alcohol

Kava is an excellent alternative to alcohol because it has similar effects but doesn’t have as many adverse side effects. Kava can help reduce anxiety and stress, while alcohol can actually increase these feelings. 

Kava is also less likely to cause liver damage than alcohol. There have been cases of severe liver injury associated with kava use, but this is a rare occurrence. It’s essential to purchase kava from reputable sources and avoid consuming it in excess to minimize potential risks. 

Reduce Anxiety Levels

Kava is a relaxant and can help you calm down and de-stress. It’s been shown to be helpful for people with anxiety disorders, and can also help relieve stress after a long day at work.

Taste Can Be Tailored to Your Preference

Kava comes in various flavors, so you can always find one you enjoy. Depending on your needs, it’s also possible to buy kava with different potency levels. It would be a good idea to start with lower-strength kava if you’re just starting out. You can always increase the kava dosage later if needed.

Disadvantages of Kava

Kava has been linked with various adverse effects, including nausea, vomiting, and diarrhea. It can also cause liver damage in some cases, so it’s essential to be aware of the risks before you start drinking kava. Additionally, kavalactones can interact with certain medications-including birth control pills. 

Kava can also negatively impact heart rate and blood pressure, so those with pre-existing cardiovascular conditions should avoid it altogether. Finally, kava is known to have an impact on various aspects of cognition so it may not be suitable for everyone who wants to improve their mood or focus. 

Different Types of Kava and How They Affect Your Body

Noble Kava

Noble kava is the most sought-after type of kava. It’s made from the plant’s roots and is known for its high quality and potency. Noble kava can help reduce anxiety, stress, and promote relaxation. It is the only type of kava that is legally exported from the Pacific Islands

The kavalactones in noble kava are more potent and can provide a more substantial effect than other types of kava. If you’re looking for the most effective kava possible, then noble kava is the way to go.

Medicinal Kava

Medicinal kava is known for having high concentrations of the active chemical compounds found in regular kava. They’re usually prepared traditionally by mixing ground root bark with water and straining out the solids before drinking.

You can drink it up to four times per day or until you feel relaxed, euphoric, or sedated enough, depending on your dosage recommendations. This type has a higher percentage of kavalactones which are responsible for the therapeutic benefits it provides.

Full Stomach vs. Empty Stomach Effects of Kava

Full Stomach and Kava

When kava is consumed on a full stomach, its effects are slowed down because it has to go through the entire digestive process. This means that it will take longer for the kavalactones to be released and absorbed into the bloodstream. Keep in mind that this will make the euphoria and relaxation you feel from drinking kava more subtle.

Empty Stomach and Kava

If you drink kava on an empty stomach, its effects will be felt more quickly because there is nothing else in your system competing with it for absorption. The downside to this is that if you have too much kava or you’re not used to its potency, you may experience nausea or vomiting.

Overview of the Chemicals in Kava

When you drink kava, the kavalactones in the plant react with your body to produce psychoactive effects. These kavalactones are then absorbed into the bloodstream and travel to the brain, where they interact with neurotransmitters to produce feelings of relaxation and pleasure. 

The half-life of kava is up to 18 hours long! This means that it can take up to an entire day for kava to completely leave the body once ingested! The specific effects you experience will depend on the type of kava you drink and your physiology.

Kavalactones and Your Liver

The kavalactones in kava are metabolized by the liver, which means that they must be processed before leaving your body. Because kavalactone metabolites can sometimes accumulate and remain in fatty tissues for a long time after intake, it is not recommended for daily use.

Kava and Your Blood

Kavalactones can also affect your blood pressure and heart rate. In some cases, kava has been associated with increased heart rate and a decrease in blood pressure. If you have any pre-existing cardiovascular conditions, it is best to avoid drinking kava altogether.

Kava and Kavalactone Side Effects

Some kavalactones, like dihydromethysticin (DHM), can cause an upset stomach in some individuals. If you experience irritation while drinking kava, it is recommended to stop using it immediately. 

Some kavalactones are also associated with liver damage. If any unusual symptoms occur, such as nausea or jaundice, it is best to consult a doctor right away.

Kava and Our Brain

Kava is known to have a direct impact on our brains. Kavalactones can also stimulate cognitive function and memory. By improving communication between our brains’ left and right hemispheres, kava might be able to help us become more creative and productive.


Kava, as a dietary supplement, can also be combined with kratom, another herbal supplement, for a more powerful effect. How long kava lasts is something that depends on many variables, but it can generally take up to 2 hours before it starts to wear off. 

With the right dosage and medical guidance from a doctor, kava may be able to help you feel better inside and out!
