Factors That Determine How Long A Kilo Lasts

A kilo of kratom can last anywhere from three months to a year — though you’ll need to store it properly. How much you take and how often you use it will be the biggest determining factor in how far a kilo will stretch.

1. Finding the Right Dose

Different effects call for varying dosages, and like with any substance; it doesn’t affect everyone the same way.

Although an increasing number of people are taking kratom, many still do not know their ideal dosage. This is important because taking too much makes you more likely to suffer from side effects, such as fatigue, headache, vomiting, etc. It’s also crucial if you want to get the most out of kratom. Some people take more than they need to and go through it faster.

Unfortunately, finding the correct dose is complex, as it depends on several things — weight, tolerance, and goals are the major ones. The best way to find your dosage is to start with low quantities and see how your body reacts. Remember that the effects may take an hour to appear.

Here are some factors to keep in mind:

  • Bodyweight — Heavier people tend to need higher doses.
  • Tolerance — It’s easy to build a tolerance to kratom if you aren’t taking breaks, requiring you to need more of it to get the same effects.
  • Goals  — If you want energizing effects, we recommend taking lower doses. You’ll need larger quantities to treat depression, insomnia, or pain.

The following sections give a good starting point based on your goals.

When Using Kratom for Pain

Higher doses are better for treating pain, thanks to one of kratom’s main alkaloids, 7-hydroxymitragynine. The standard kratom dosage for pain relief is 5-10 grams, so one kilo can last up to 100 doses in a worst-case scenario.

Generally, red vein kratom powder is ideal for treating aches and pains, but keep in mind these strains are very potent.

These are the best strains for treating pain:

  • Red Maeng DaThis strain is great for daytime pain relief thanks to its energizing effects. Because Maeng Da strains tend to be very potent, start with less than usual.
  • Red BaliThis is one of the best strains for pain and can help you fall asleep at night. 
  • Red BorneoThis is a good strain for reducing anxiety but still has excellent analgesic effects.

When Using Kratom for Opiate Withdrawal

One of the most common uses of kratom is to combat opioid addiction. The body adapts to opioids’ effects after repeated use, and stopping can cause severe withdrawal symptoms. Kratom acts on the opioid system and can help relieve some of the pain and discomfort associated with it.

Most people need large amounts of kratom — between 5 and 15 grams — to control opioid withdrawal symptoms. Therefore, a kilo of kratom may be about 65 doses.

Again, red varieties are ideal for opiate withdrawal, as they relieve pain and many other withdrawal symptoms. However, all colors of Maeng Da can also be helpful.

These are the best strains for opiate withdrawal:

  • Red Maeng DaBoth red and green varieties are ideal for treating opioid addiction.
  • Red BaliBali is excellent for relieving common symptoms of addiction, such as anxiety and muscle aches.
  • Red ThaiHere’s another excellent strain for relaxing muscles and the mind.

When Using Kratom for Energy

Kratom can be a great help when you need an energy boost for long days. That’s why many students or people who work hard use it for better performance.

Lower doses — between 2 and 6 grams — are usually better for energizing effects. Approximately one kilo of kratom can last you about 170 to 500 doses.

White strains are ideal for increasing energy as they have excellent stimulant properties. However, most green strains can also help you achieve these goals.

These are the best strains for energy:

  • Maeng DaFor energizing effects, we recommend going for green or white varieties.
  • White BorneoAn excellent strain for increasing energy and mood.
  • Green IndoTo achieve energizing effects with this strain, we recommend taking small amounts.

When Dosing for Anxiety & Depression

Although kratom is not a cure, it can be a great tool to combat anxiety and depression. This is thanks to its high content of 7-hydroxymitragynine and speciogynine, the main ones responsible for producing relaxing effects.

The ideal dose for anxiety is 2–6 grams. However, there is no correct dose for depression, as the mood-enhancing effects of kratom can occur at both ends of the spectrum.

As usual, start with low amounts and increase until you find your dosage.

The best varieties for relieving depression are green and white, but use red or green strains for anxiety, as white strains can cause anxiety in some people.

These are the best strains for anxiety and depression:

  • Green Malay This is one of the most relaxing green strains and is also an excellent social lubricant.
  • Red ThaiKeep in mind that large amounts can make you sleepy, but this strain is great for reducing stress and providing a more positive outlook.
  • White Maeng Da — Be careful since it’s a white strain; it won’t take much to get you going.

2. Measuring Your Kratom Properly

Properly measuring your doses is crucial if you want to accurately estimate how long a kilo of kratom will last. If you don’t know precisely how much kratom you’re taking, your math will be wrong, and you may run out of kratom sooner than you thought.

The best way to measure your kratom powder doses is to have a small scale. If you cannot access one of these, you can measure it with a spoon, but remember that it is less accurate.

Kratom powder can have different levels of grind, affecting the volume that fits inside the spoon.

Amounts of kratom per teaspoon:

  • Kratom coarse ground — approximately 2.7 grams
  • Ultrafine ground kratom — up to 3.5 grams

For a more precise use, we recommend that you always use the same spoon — also, make sure that it is flat and not heaped.

3. Taking Breaks & Avoiding Building a Tolerance

The biggest reason to space your kratom doses is to help you avoid developing dependence or addiction. However, the effects can lose their charm if you use it too much, leading you to need larger doses and go through it faster.

Mitragynine — the main component of kratom — can last up to 24 hours in your blood. If you need to use it frequently, space your doses by approximately 12 hours.

But, if you don’t need to use it frequently, you can afford to take it every 6 hours when necessary.

Tips for spacing kratom doses:

  • It’s best to take one or two days off every week and then a whole week off every month to keep your tolerance low.
  • Record your doses and experiences so you will have an idea of what works for you and what does not.
  • Alternate it with different herbs and supplements. Coffee, yerba mate, and guarana are excellent herbs for energy, while passionflower, damiana, and cannabis are helpful for sleep.

Still, we recommend that you avoid making this a habit, as it could lead to a dependency on both.

Potentiators: A Simple Way to Boost Kratom’s Effects

Did you know you can make a kilo of kratom last even longer by combining it with other substances or compounds that synergize, boosting its efficacy?

These are called kratom potentiators, and they work well enough that you need to be careful when trying them.

These compounds work by either increasing the absorption of the kratom alkaloids or by interacting with them, creating a stronger effect.

Following up, we’ll briefly review the most used ones.


Caffeine is a stimulant found in coffee and many commercial energy drinks. Drinking a cup of coffee or tea before taking kratom can enhance its stimulant effects.

Grapefruit Juice

Grapefruit juice contains compounds that can increase the absorption of kratom alkaloids in the body, leading to a stronger effect. In fact, it’s known to interact with many drugs for this reason.


Turmeric is a spice that contains curcumin, a compound that has been shown to increase the potency of kratom. Taking turmeric along with kratom can enhance its effects, making your supply last longer.


Magnesium is a mineral that can increase kratom’s potency by increasing absorption. Magnesium supplements or foods that contain lots of it, such as leafy greens and nuts, can be taken before taking kratom to make the experience more powerful.

Black Pepper

Black pepper contains piperine, which can also strengthen your kratom dose. Although the taste won’t be pleasant for some, taking black pepper and kratom together can enhance the effects.

Cayenne Pepper

Cayenne can be rough going down, but a little can go a long way. It might help to combine cayenne with honey or juice to make it taste better. Still, it’s a good potentiator if you can stand it.

Lemon Juice

Lemon juice, and other citrus juices, can help increase kratom’s effects. It also helps make it taste better. Add some to your kratom tea, and it will go down much easier.

How Much Does a Kilo of Kratom Cost?

The cost of kratom can vary greatly depending on the vendor you go to, as prices range from $90 to $240 per kilo.

The seller is one of the most influential factors in the price of kratom. Quality, testing, and the market play a role, but the vendor sets the price. Some companies do little as far as testing or extra measures go but still charge far more than average (about $120 a kilo).

Here’s an approximate price range of kratom across the US:

  • 1 oz (28 g): $6-$12
  • 8 oz (250 g): $30-$55
  • 35 oz (1000 g/1 kilo): $90-$240

Cheapest Kratom

To get the cheapest kratom, first, research the different options available. Our list of the top ten best vendors is a good place to start since it gives a good idea of pricing, selection, and other important information.

Also, go for kratom powder, as the capsules and tinctures are more expensive because they require more time to manufacture.

It might help to look at the different kratom strains — sometimes, the most popular varieties, such as Bali, are less expensive. However, this is less common now that kratom is so popular.

Most Expensive Kratom

Vendors with the most expensive kratom often — but not always — have better quality products, as they pass strict quality controls on their products. But as we said, some vendors charge much more than they should.

Rare strains like  Red Dragon or Green Hulu Kapuas sometimes cost more due to supply and demand, but most of the added cost comes from testing and other measures that make the kratom better.

Conclusion: How Long Does a Kilo of Kratom Last?

How long kratom lasts depends exclusively on what you use it for. Generally, if you use it as a stimulant, it will last longer than a sedative since it requires lower doses.

You can also use different kratom potentiators or alternate it with herbs or supplements with similar effects to further stretch your kratom.

Finally, remember to keep track of your dosages and experiences with them, as it will help you avoid suffering from unpleasant side effects — including tolerance and addiction — and can help keep you from using too much.
