Since there is no universal dosage for CBD, finding the right one for you isn’t an easy task. There are a number of factors that go into determining your personal dosage to get the results you are seeking from CBD. Some of these major factors include:

  • CBD strength
  • Delivery method
  • Body weight
  • Body chemistry
  • Severity of condition

In addition, cannabidiol acts on multiple molecular pathways in the body, so everyone’s experience will be different based on the factors listed above, according to experiments conducted at King’s College London. In this guide, we will show you how these variables play a role in determining how much CBD you should take.

How much CBD should I take?

There is no direct answer to that question, but delivery method of CBD plays an important role in determining dosage. Each delivery method has its own unique potential for your body to absorb the cannabinoids. This is a concept known as bioavailability, which we explain in greater detail below.

Before you can determine your CBD dosage, you will need to know exactly how much CBD you are getting in the first place, expressed in milligrams (mg) on the label. This can be confirmed by looking at lab test reports for the product to make sure they contain the exact amount of CBD as advertised.

You can always experiment with slightly higher or lower potencies until you find what works best.

The thing about CBD is that it’s not exactly cheap, and taking an excessive dose isn’t necessarily going to provide any additional benefits. On the flip side, if you’re not taking enough, you might not even notice the benefits, which can be just as much of a waste of money. Here are some of the most common ways of taking CBD, and how to determine your dosage for each one.

For CBD oil and tinctures.

CBD oils are oil-based tinctures that are taken sublingually, which means taken under the tongue. They are not the same formula used for vaping—we can’t stress this enough. However, finding your dosage is actually a very similar process. The graphic above can also be applied to CBD oil dosages.

First, you’ll need to divide the total amount of CBD per bottle by the size of the bottle in mL. This will give you the amount of CBD per mL, which is an important number to know. Most CBD bottles come with a dropper that is designed to pull exactly 1 mL of liquid when you squeeze the rubber bulb. Some bottles will actually have the measurements in mL on the dropper itself for added precision. Once you know how much CBD is in each mL, you’ll know how much to take. A 1 mL dropper holds approximately 20 drops of liquid. If you really want to get technical, you can divide the mg/mL by 20 to get the amount of CBD in each drop, but it’s not necessary to count each drop.

Tip: Hold the CBD oil tincture under your tongue for at least 15-30 seconds before swallowing so that it gets absorbed into the blood vessels. Otherwise it will have to pass through your digestive tract.

For CBD edibles and capsules

CBD edibles and CBD capsules are similar in their effectiveness in that they both must pass through the digestive tract. For this reason, your ideal dosage for capsules and edibles are going to be similar. One of the biggest advantages of these delivery methods is that they utilize predetermined doses.

Most of them state the exact amount of CBD per gummy or per capsule. If by some chance it only states the total amount of CBD, then you can just divide that by the number of gummies or capsules per bottle. This will tell you exactly how much CBD is in each one, which is essential for figuring out how many and how often you should be taking them, based on your individual needs.

Recommended dosages for CBD

Keep in mind, your dosage is subject to change based on the condition you are trying to treat. Also, these dosages are for taking CBD orally, so if you’re vaping it, you might not need as much due to the higher bioavailability of vaped CBD. Here are a few recommended doses:

Increase appetite in cancer patients – 2.5 mg CBD (best when combined at a 1:1 ratio with THC, if it’s available where you live)

Chronic pain – 2.5-20 mg CBD

Epilepsy – 200-300 mg CBD

Sleep disorders – 40-160 mg CBD

Social anxiety – 40-300 mg

Use this guide as a reference, but keep in mind that finding your dosage typically may also require some trial and error. You may also want to consult your doctor if you are using CBD for medicinal benefits, especially if you’re taking medication.
