Kratom Dosage Guide: Serving Sizes, Conversions and Label Basics
By Andrew Klein. Last updated October 14, 2026.
Looking for a kratom dosage guide? Here is the short version: follow the serving size on your label, start small, and never go past the label serving. This page covers how much leaf powder is in each KratZilla capsule, how to convert capsules and teaspoons to grams, and how to measure powder accurately. If you are still deciding on a format, our kratom capsules vs powder guide compares the two side by side.
What you will not find here is a chart that matches a number of grams to an “effect.” Kratom is not approved by the FDA for any use, and nobody can promise how a given amount will feel for you. What we can give you is accurate math and plain guidance.
Before you read: This article is for general information only and is not medical or legal advice. Kratom is not approved by the FDA for any use. Talk to a qualified healthcare provider before using any botanical product, especially if you take medication.

Quick answer: follow the label, start small
There is no single “correct” kratom dosage. Body size, food, tolerance and the product itself all vary, and research on kratom in people is still limited, according to the National Institute on Drug Abuse. That is exactly why a label-first approach makes sense:
01
Read the label serving size on your package and use it as the upper limit, not a target.
02
Start small. First-time customers often begin below the label serving.
03
Wait before taking more. Do not take a second serving because you have not noticed anything yet.
04
Do not exceed the label serving in one sitting or in one day.
05
Do not combine kratom with alcohol, medications or other substances.
Not for anyone under 21, or anyone who is pregnant or nursing. Do not drive or operate machinery until you know how kratom affects you.
Read the label
Serving size on KratZilla labels
Every KratZilla package lists a serving size on the label.
A few things worth knowing about how we label:
Capsules
Each vegetable capsule holds 0.6 g (600 mg) of Maeng Da leaf powder. That fill weight is the same across Green, Red and White.
Powder
The label serving is listed in grams, which is why we suggest a digital scale (more on that below).
Same weight across colors
Green, Red and White Maeng Da use the same label serving. Leaf color reflects harvest timing and drying, not a different serving size. Our Maeng Da strains guide explains the differences between vein colors.
Conversions
Capsule to gram conversion table
This is a weight conversion, not a recommendation. Always check it against the label serving on your package.
By package size
Quick tip: capsule counts on other brands are not interchangeable with ours. Fill weights vary across the market, so always do the math per brand.
Measuring powder
Teaspoon to gram conversion (and why a scale is better)
A level teaspoon of kratom powder weighs roughly 2 to 3 g, but that number moves around a lot.
Why a spoon is unreliable:
Grind and packing
A fine, tightly packed teaspoon can weigh noticeably more than a loose, fluffy one.
Level vs heaped
A slightly rounded spoon can add a surprising amount of weight.
Spoon size
Kitchen teaspoons are not standardized.
A small digital scale that reads to 0.01 g takes the guesswork out. Zero (tare) the scale with your cup on it, add powder slowly, and stop at your measured amount. Weighing also makes it easy to keep a simple log, so you are comparing the same amount every time. For mixing and preparation ideas, see how to take kratom.
Prefer to skip measuring altogether? Capsules give you the same 0.6 g every time.
Timing
Onset and duration
People often ask how long kratom takes to kick in and how long it lasts. Honest answer: it varies from person to person, and published research on timing in humans is limited.
What matters most for measuring:
Do not “top up” early
Taking more because you have not noticed anything yet is one of the most common ways people end up over the label serving.
Food changes timing
A full stomach can slow things down compared with an empty one.
Capsules dissolve first
Capsules have to break down before the powder is absorbed, so they may be slower than loose powder.
Food and water
Empty stomach vs with food
Some customers take kratom on an empty stomach and some prefer it after a light snack. A few practical points:
- An empty stomach is the situation where customers most often report an upset stomach.
- A small snack beforehand is a common choice for anyone prone to nausea.
- Whatever you choose, keep it consistent so you are not changing two things at once.
- Drink water. Kratom powder is dry and bitter, and staying hydrated is simple good practice.
Side effects
Nausea and why it happens
Nausea is one of the most commonly reported side effects of kratom, along with dizziness, according to FDA and NIDA. Customers report it most often when:
- they take more than the label serving,
- they take powder on an empty stomach, or
- they take a second serving too soon.
Some people call the combination of dizziness, nausea and unsteadiness “the wobbles.” It is a sign you have taken too much for your body. Stop, rest, drink water, and do not drive.
If it is serious
If symptoms are severe, or you think someone has taken too much, call 911 or Poison Control at 1-800-222-1222.
Kratom is not risk-free. Other reported side effects and risks are covered in our kratom safety guide, linked below.
Regular use
Tolerance and taking breaks
Regular, frequent kratom use can lead to tolerance and dependence, and stopping after regular use can be difficult and uncomfortable, according to NIDA. Our kratom safety guide covers dependence in more detail. That has two practical implications for serving size:
Do not raise your amount to keep up with tolerance.
The label serving stays the ceiling no matter how long you have been a customer.
Build in regular days off.
Many customers keep kratom as an occasional choice rather than a daily habit.
If you are finding it hard to cut back or stop, talk to a healthcare provider, or call the free, confidential SAMHSA National Helpline at 1-800-662-4357.
Do not mix
What not to combine with kratom
Do not combine kratom with:
ā
Alcohol
ā
Prescription or over-the-counter medications, unless your healthcare provider has said otherwise
ā
Other substances, including other botanicals and recreational drugs
ā
Concentrated 7-OH or “enhanced” products
A CDC review of overdose deaths where kratom was detected found that most of those deaths involved multiple substances (CDC MMWR). KratZilla sells natural leaf powder and capsules only, never 7-OH, extracts or “enhanced” products. Our guide to natural kratom leaf vs 7-OH explains why those are a different category.
Before you order, check where kratom is allowed. Kratom’s legal status varies by state, county and city, and it changed often in 2026. As of October 14, 2026, see our kratom laws by state guide for current details.
