Mindfulness & Anxiety

How Much CBD Should You Take?

An effective dose of CBD is different for everyone. The most important thing is understanding how to measure and take CBD in an effective way. Only then is it possible to gradually increase dose until a result is achieved.

Quick Introduction

  • CBD dosage varies for every person
  • It's important to know how much CBD is in a product
  • Research on dosing for conditions like sleep, anxiety, and pain is limited
  • Consult a doctor about possible drug interactions

Calculate Serving Strength

A bottle of CBD oil, if properly labeled, will list the total number of milligrams of CBD contained in the bottle. Some typical concentrations include 300, 750, or 1000 milligrams.

One can calculate the strength of a serving by dividing number of milligrams in the bottle by the number of servings in the bottle. For example, a 1 oz bottle that uses a 1 mL dropper contains about 30 servings. If the bottle contains 300 mg of CBD and 30 servings, there are 10 mg of CBD in each serving.

Estimated CBD in a serving based on bottle strength.

StrengthBottle Dropper
Low100 mg3.3 mg
300 mg10 mg
Medium500 mg17 mg
750 mg25 mg
High1,000 mg33 mg
1,500 mg50 mg
Extra Strength2,500mg83 mg
5,000mg167 mg

Consider Your Weight

Your body processes CBD at a different rate than your neighbor’s. However, you can use your weight as a starting place for understanding dosing.

One general guideline suggests 1 to 6 milligrams of CBD for every 10 pounds of body weight, increasing the dose based on the severity of symptoms.

A dose may be higher or lower depending on the condition one is trying to treat. A dose for sleep may be different than a dose for pain.

Estimated dose based on body weight and severity of symptoms.

Mild6 mg9 mg12 mg18 mg22 mg
Medium9 mg12 mg15 mg22 mg30 mg
Severe12 mg15 mg18 mg27 mg45 mg

Dosages used in clinical trials are often much higher than servings listed on bottles for commercial sale. If you read a study that suggests CBD cures anxiety, make sure you look to see what dose was used in the trial.

Compare Delivery Methods

After reading the label and using weight to estimate a dose of CBD (number of milligrams) that may provide relief, choose an effective way to take a dose. Options include oils, gummies, capsules, and vapes or flower. Each delivery method works differently and takes a different amount of time to work.

Estimated time each CBD delivery method takes to work.

MethodTime to WorkTime it Lasts

Vape1-10 minutes1-4 hours
Edible45 minutes1-8 hours

Give products time to work before taking more. Especially with edibles or gummies, it’s not smart to take multiple doses before understanding how the CBD is working in your body.
