Here’s how to calculate your CBD dose
Use the dosage calculation formula below or try out our CBD dosage calculator to find the perfect CBD product and dose for you.
The dosage calculation guide below will answer a few of the most common questions first-time users ask when beginning CBD, such as how do I calculate the optimal CBD dosage, how do I choose the right CBD formula, and can I change my CBD dose frequently before I find the amount that works best for me.
Step 1: How do I calculate the optimal dosage
We discussed microdosing and weight-based dosing above in the section titled how much CBD do I take?
To summarize, microdosing involves taking tiny doses of CBD many times during the day. You will typically divide the dose you choose (e.g., the minimum effective dose of 25 mg CBD) into ten microdoses taken about every hour. The research on microdosing is scant at best and body-weight dosing is recommended due to the wealth of clinical research that supports its effectiveness.
CBD is a very forgiving natural medicine. Its excellent safety profile leaves plenty of wiggle room for you to experiment safely while you find the optimal dose. The process of gradually increasing and moderating your CBD intake until you find the most effective daily dose is called titration. It may take just a few days up to a couple of weeks to titrate depending on your individual response to CBD.
Our CBD dosage chart at the top of this article is recommended to calculate your weight-based dose unless you are in between the listed weight classes and want an amount more specific to your exact weight. Then you should use the following dosage formula to calculate the optimal CBD dose by plugging in your exact weight and preferred strength:
[TOTAL WEIGHT] x [STRENGTH OF DOSE] = RECOMMENDED AMOUNT OF MILLIGRAMS OF CBD PER DOSE
The following chart provides the CBD dosage recommendations for mild strength, average strength, and maximum strength in kilograms (kg) or pounds (lbs):
Chart: CBD Dosage By Pound or Kilogram |
|||
|---|---|---|---|
| Single Unit Weight Metric | Mild Strength Dose | Average Stength Dose | Maximum Stength Dose |
| 1 lbs U.S. Imperial Pound |
0.25 mg / lbs | 0.5 mg / lbs | 1.5 mg / lbs |
| 1 kg Metric Kilogram |
0.55 mg / kg | 1.1 mg / kg | 3.3 mg / kg |
Here is how you would use the dosage formula to calculate the CBD dose for someone who weighs 100lbs:
Example #1:
Weight: 100 lbs.
Dosage Strength Preference: Average Dose
Optimal Dose Calculation: [100 lbs] x [0.5 mg] = 50 mg of CBD Recommended Per Dose
Here is another example for a person weighing 200lbs:
Example #2:
Weight: 200 lbs.
Dosage Strength Preference: Average Dose
Optimal Dose Calculation: [200 lbs] x [0.5 mg] = 100 mg of CBD Recommended Per Dose
Substitute your current body weight and your preferred CBD dosage strength (i.e., average, mild, or maximum strength) to find the perfect CBD dose for you.
Step 2: Finding the right CBD strength for you
You’ve figured out the perfect CBD dose for you based on your body weight. It’s now time to choose the best CBD formula strength to meet your needs.
What is the one thing all CBD products have in common, be it oil tinctures, softgels, gummies, baked goods, concentrates, isolate powders, topicals, or vapes? They contain CBD of course!
The first thing you must do is figure out how much CBD is in the product you plan to take. CBD products display various numbers on the label, such as “750 mg,” “3,000 mg,” “12,000 mg,” et cetera. These numbers tell you the strength of your CBD product and account for how much CBD is in it calculated in milligrams (mg). You divide the strength of your CBD product by the number of servings in it to determine the potency of each dose you take.
Here is an example of how you would determine the potency of a 1 mL dose of Cannabiva 12,000 mg Full Spectrum CBD Oil using our potency calculation formula:
[TOTAL CBD IN THE BOTTLE] / [TOTAL MILLILITERS IN THE BOTTLE] = AMOUNT OF CBD PER DOSE
Example #1:
Cannabiva 12,000MG Full Spectrum CBD Oil (30 mL bottle)
[12,0000] / [30] = 400 mg of CBD per dose
In the next example, we will determine the potency of a 1 mL dose of Zero High 10,000 mg Pure CBD Isolate Oil:
Example #2:
Zero High 10,000MG Pure CBD Isolate Oil (30 mL bottle)
[10,000] / [30] = 333 mg of CBD per dose
Apply our dose potency formula to any product for which you know the total amount of CBD along with the exact amount of servings in the package. Not sure how many servings your CBD product contains? Check the “Nutrition Facts” panel on the product label to find the serving size and number of servings.

Step 3: Adjust your dosage based on how your body responds
You now know the optimal CBD dose you should take and how to measure the correct amount of CBD using our potency calculation formula.
The last step is to take your first dose and begin titration (gradually increasing and moderating your CBD intake until you find the most effective daily dose). Only you know how much CBD helps you feel better, so it’s important to pay careful attention to how you feel before, during, and after each dose until you find the right amount for you.
CBD has a well-established safety profile. It’s also a very forgiving natural medicine that leaves you quite a bit of wiggle room to experiment safely while you find the optimal dose. CBD is not psychoactive and will never cause you to feel euphoric or “high” after taking it, even if you take more than the recommended CBD dosage.
Side effects are extremely rare when you take CBD as directed. Clinical trials typically use CBD dosages that range from 25 mg up to as much as 1,200 mg or more, depending on the study and specific wellness concerns being scientifically researched. Reported side effects (with a less than 0.5% chance of occurrence) are often similar to placebo and may include dry mouth, increased thirst, increased or decreased appetite, stomach upset, or drowsiness. Allergic reactions are not commonly reported when taking CBD, but you should talk to your doctor if you are unsure.
