Various studies are being conducted to explore the effects of CBD products on our bodies. Because of this, there is still much to determine when it comes to taking CBD products.

One of the most asked questions of people who plan on using CBD is, "How much CBD should I take?". This is an important question to answer since you won't likely enjoy the potential benefits of CBD if you take a dose lower than necessary. On the other hand, you could be at risk of experiencing side effects if you take too much CBD. 

In this article, we will discuss different things that we need to understand about CBD Dosage. 

How Much CBD Should You Take?

We will be straightforward in answering this simple question: there is no "right" CBD dosage. The optimal dose for a person may vary depending on various factors, so no one dosage would work best for all people. 

Instead of suggesting the "right" dose, we will provide some factors to consider and tips to help identify a good dosage for you.

Factors to Consider when Determining CBD Dosage

Some of the different factors to keep in mind when determining the right dosage for you are as follows:


Your weight can significantly affect how little or how much CBD you need to achieve the desired effects. In general, the heavier the person is, the higher the dose they need. On the other hand, lower doses would likely work well on smaller people.

Body Chemistry

In addition to bodyweight, a person's unique body chemistry should also be kept in mind when determining the right dosage of CBD. 

Since CBD attaches to our CB2 receptors upon ingestion, it may affect our endocannabinoid system. Because of this, we should consider the sensitivity of this system. For example, a person with a highly sensitive ECB system would probably need a lower dose of CBD.

This is one reason why two people of the same weight will not necessarily experience the same effects even if they take the same dose.


By concentration, we are referring to the total amount of CBD substance that can be found in a product relative to overall product volume. 

When determining your CBD dose, you will also need to consider the product's serving size. 

For example, if CBD oil contains 30 ml of tincture and 1500 mg of CBD, you will get 1500 mg of CBD if you ingest the entire tincture. 

So, if your doctor recommended a dosage of 50 mg, you would need to take only 1 ml (1500 mg/30 ml = 50 mg/ml) of the tincture. If you have been prescribed 100 mg of CBD, you would need to take 2 ml of the tincture.

The dosage is easier to track when you take CBD capsules, as one capsule already contains a specific serving size of CBD. For example, if a capsule contains 50 mg and you have been prescribed with 100 mg of CBD, you would take 2 capsules. 


If you have already been taking CBD products for quite a while, you may have already developed tolerance to the substance. This means that you may experience reduced effects even when you take the same dosage. To address this, you may have to gradually increase your dosage so you can achieve the desired results.

Of course, you should never adjust the dosage on your own. You should always seek the advice of a medical professional before you make any changes to your CBD dosage.

Route of Administration

Keep in mind that different forms of CBD are absorbed differently by the body. This is because different ways of administration will affect the bioavailability of CBD. Bioavailability is the scientific term used to refer to the amount of substance that reaches and delivers the desired results.

CBD products taken sublingually or via inhalation tend to have the highest bioavailability, so you may need to take lower doses when you use such products.

On the other hand, CBD products taken orally have the lowest bioavailability because the CBD must first pass through the liver where a significant amount of the substance is metabolized (what we call the first-pass effect). Because of this, you would need to take higher doses of capsules, lozenges, or gum to enjoy the substance's effects. 

CBD Extract Type

In addition to the dosage form, you should also consider the type of CBD extract that the product contains. Among the three types of extracts, CBD isolate provides the highest concentration of CBD as it contains pure CBD extract. Because of this, you may need a lower dose of the product if you are using one that contains CBD isolate.

However, there are still mixed opinions about this topic. Some studies claim full, or broad-spectrum CBD extracts are more potent because of the synergistic effect of the other cannabinoids that these products contain.

CBD Biphasic Action

CBD can deliver biphasic action, so you may experience one set of effects when you take a lower dose and experience an entirely different set of outcomes when you take a higher dose. 

Because of this, you should keep a record of the changes you felt when you took lower doses, as well as the symptoms you noticed when you take higher doses. This information may help your physician know how much to prescribe when you wish to enjoy a specific potential benefit of CBD. 

Doctor's Recommendation

A doctor's recommendation is the most critical factor of all. You should always work with a medical professional to help understand the right dosage for your needs, especially with substances like CBD. 

Your doctor will consider the factors mentioned to determine a dosage that is safe and effective for you.

CBD Dosage Tips to Keep in Mind

In addition to the factors to consider, keep these tips in mind:

There is no "one size fits all" when it comes to the dosage of CBD.

As mentioned in the previous sections, the right CBD dose may vary from one person to the other because the physiology of each person is different. Our endocannabinoid systems are incredibly complex and may work differently from one person to the other. 

That's why you need to know how to determine a dosage that is tailored specifically to your needs and physiology.

Start by taking low doses.

Your physician will likely recommend that you start with the lowest possible dose, usually 10 to 25 mg. Follow your physician's recommendation, but make sure to observe the effects of the supplement on your body. If you are not feeling the expected results, notify your physician so he or she can adjust your dose accordingly.

Consider following the Dr. Dustin Solak Dosing method.

Dr. Dustin Solak is a medical practitioner that lives in Maine, USA. He was one of the first to introduce the "start small and go slow" method. 

The first thing that you need to do is score yourself out of 10 for the following criteria: ease of breathing, body comfort, overall condition, mood, and severity of symptoms. 

After that, take about 5 mg of CBD. After an hour, examine yourself and rate the mentioned criteria out of 10. If you took the CBD sublingually or via inhalation, you could evaluate yourself 15 minutes after consumption. 

Do this in the morning and at night. If you haven't felt anything, you can increase your dosage by 10 to 15 mg. You can stop increasing the dose when you noticed that it is no longer causing any significant improvements to what you are feeling.

Hold course.

Take one dosage for a few days while observing its effect. Do not give up after just one day of taking it. It is only after a few days that you can accurately gauge whether the dose is too low or too high for you.

Expect trial and error.

Even if you are working with a medical expert, it can be difficult for you both to get the right dose in just one try. It might take a while, so be patient. 

If you experience any side effects, stop the use or lower the dose.

Studies show that quality CBD is virtually free of toxins, but there is still a possibility that you will experience side effects. Some of the most common side effects are lethargy, fatigue, and diarrhea. If you experience any of these side effects, you should discontinue use and notify your doctor right away.

Use a CBD Dosage calculator when performing CBD dosing.

If you find it difficult to determine how much of a CBD product you should take, you may want to use a CBD calculator. Some of the information that you need when using these programs is the concentration of the CBD product and the recommended dosage of your physician. 

Can You Overdose on CBD?

Studies conducted in 2011 and 2017 appeared to show that some people can take up to 1500 mg of CBD daily without experiencing any side effects. Moreover, a report from the National Cancer Institute states that since cannabinoid receptors are not found in our brainstem areas, lethal cannabis overdose will not occur. However, we strongly recommend only taking the dose recommended by your medical professional and not experimenting with higher than recommended doses.

Final Words

Studies show that taking high amounts of CBD will not likely cause serious adverse effects. However, keep in mind that the CBD industry is still relatively new and the long-term effects of high doses of CBD have not yet been extensively studied. Moreover, consuming high amounts of this substance may eventually overwork and damage your liver. 

These are the reasons why you should seek professional recommendations when determining how much CBD to take, in addition to following the CBD dosage tips that we have provided in this article.
