CBD Dosage Calculator Benefits, How to Choose, Measure, And Use

Many people are discovering CBD as a potential treatment for various diseases. It is gaining popularity due to its immense medicinal benefits, however, very rarely we come across proper prescriptions or guidelines about dose calculation of CBD. This is where we identify the need for a CBD dosage calculator.

There a lot of articles about the benefits of using CBD but only very few articles describe the methodology on dosing CBD.

Understanding the way CBD works and how to make it work for you can be very confusing. Especially, since the industry is still very new and there’s still a lot of animal experimentation about the dosing and all.

Therefore, it is crucial that we come up with an immediate solution i.e. CBD calculator. It helps to find out the most accurate CBD dosage in milligrams or percentage.

Users are usually told to take a drop per day or more by the reviewers on blogs. While this can be a correct dosage for one individual, there is no way to know if it is right for all the individuals out there.

It does not consider essential factors such as the concentration of the CBD; the severity of the condition under treatment; the weight of the user; and the user’s body chemistry.

This essentially means that the same dosage is not applicable to everyone.

Generally, to determine the accurate dosage for you, it is better to start with a small dose.

Start with a certain dosage for about three days, so that your body can adjust to the dose and its effects.

If you feel any discomfort from using a certain dosage, you may be using too much and you should decrease it.

Here comes the role of CBD dosage calculator that accurately tells you your dose according to your weight and BMI, taking into account your age and physique.

It also changes your dose depending on the strain of CBD you are taking or its concentration.

What is Cannabidiol (CBD)?

Cannabidiol (CBD) is a natural compound found in cannabis which was discovered in 1940. It is one of the 113 cannabinoids found in hemp. In 2008, the American Food and Drug Administration approved cannabidiol (CBD) as a prescription drug for childhood epilepsy. CBD should not be confused with Tetrahydrocannabinol (THC). THC is the component of cannabis that is responsible for the “high” feeling when taking hemp.

While THC is illegal in some countries, CBD is legally allowed because it does not have psychoactive effects like THC. Cannabidiol (CBD) has been listed in EU Cosmetics Ingredient Database and EU Novel Food Catalogue.

What are the Benefits of CBD?

The health benefits of CBD include treatment of the obsessive-compulsive disorder (OCD), osteoporosis, reduction of inflammation, psychosis relief, suppression of muscle spasm, reduction of nausea, killing bacterial growth pain relief, anti-seizure agent, anxiety-relief, cancer treatment, diabetes treatment, and insomnia treatment.

CBD has also been found to have positive effects on the heart and the circulatory system in general. Cannabidiol (CBD) is also used by several athletes when recovering from injury.

Despite the many benefits, CBD also has side effects such as drowsiness, diarrhoea, loss of appetite, tiredness and general weakness. Because of this, it is important that CBD dosages be administered with care and professional caution.

How To Choose Your CBD Dosage?

The right dosage per individual will depend on several factors such as the ailment, medical history, the mg/ml of CBD, the physiochemical constitution of an individual’s body, diet and body weight, a rate of metabolism and activity levels.

It has been established scientifically that the receptors in the endocannabinoid system are responsible for the way our bodies react to CBD. Therefore, changes in the physiological makeup of an individual will have a profound effect on the appropriate CBD dosage requirements.

  • Estimate based on your body mass

CBD dosage has been found to be directly proportional to body weight. Increase in weight means an increase in CBD dosage and vice versa. Lean people will need lower concentrations of CBD than heavy people.

For someone weighing about 68kg, starting dosage will be about 18mg. An individual weighing about 100kg can begin with a dosage of 22.5 mg. This can then be gradually increased depending on the severity of the ailment.

Honest Marijuana has developed a template that can serve as a guide for CBD dosage based on weight and severity of pain. You can check https://honestmarijuana.com/cbd-dosage-calculator/ for reference.

Individuals with more weight will require more CBD. To determine your proper dosage, you can take 1-6 mg for every 10 pounds of body weight based on your level of pain.

For instance, a 200lb patient can take 20mg – 33mg as their starting dosage. While a person with 150lb weight may take 15mg – 25mg.

  • Start small

It’s not best to follow your friend’s dosage or the dosage taken by some person on Reddit even if you have the same body mass. Each has different built, medical conditions, treatments, and use of substances.

That’s why our bodies are adapted to respond differently though looking at the bigger picture, a similar cumulative effect is achieved.

Thus, it is important first to determine your initial dosage based on your weight, watch your body’s response to that amount and increase gradually while still gauging how your body responds to each dosage till you find the most appropriate for you.

  • Go for a consultation

You must not leave your physician out of your treatments, especially if you have an existing medical condition. Make a consultation with your physician to assess if CBD can interfere with your medical condition treatment or not.

Doctors are trained to prescribe drugs. Though CBD application is an evolving area of knowledge, a competent doctor that is familiar with your medical history might be in an excellent position to recommend an optimum dosage for you.

It is important that you ask a doctor that has at least basic knowledge of CBD and who is familiar with the way your body works.

  • Know the content of the product

You need to know the nature of the CBD oil you are using, i.e. whether it is a pure extract or if the extract has been mixed with other ingredients. The purer the hemp oil, the higher the concentration of CBD and vice versa.

Some CBD products aimed at achieving an array of objectives, and this may affect the CBD concentration. Therefore, as much as possible, check the content list on the bottle, tincture, etc.

  • Read the label on the CBD oil bottle

On the CBD oil product, you will find a label stating the concentration of CBD per serving (usually in milligrams per serving). For example, if your product contains 30 mg per serving and serving size is equivalent to 10 drops.

This means each drop contains 3.0 mg of CBD per drop. If an individual needs 27 mg of CBD, all he or she needs to do is divide 27 by 3.This will give an equivalent of 9 drops.

  • Monitor what works for you

As had been said earlier, our bodies’ physio-chemical systems differ. Therefore, you should carefully monitor how your body responds to the initial dosage. It is better to start with the maxim -“aim small, miss small.”

Start with as little dosage as possible and document how your body reacts, noting side effects if any. You can then gradually increase the dosage as time goes by.

Measuring Your CBD in a Tincture

One of the most popular methods of administering CBD is using a tincture. This method is quite effective because the oil does not pass through the lungs and the liver which make it remain potent when it reaches the bloodstream.

Tinctures are produced by using grain alcohol to extract CBD from cannabis flower with low heat. Additives are then included to improve the taste of the extract. A lot of early users of CBD prefers tinctures. The quantity of hemp oil in a bottle is measured in millilitres (ml). The quantity of CBD in the oil is measured in milligrams (mg).

You can easily measure CBD tincture using the dropper and placing the tincture under your tongue.

Hold it there for few seconds (30-90) before you swallow, this allows absorption of the tincture into the systemic capillaries on the underside of the tongue.

  • How to measure the CBD dosage in a dropper of tincture?

The dropper is used in administering the oil, therefore to know how much CBD oil you should take, you must determine the capacity of the dropper.

A dropper normally holds 1ml of liquid. Once you know the amount of CBD in one ml, you can calculate your dose.

Milligrams of CBD in a Dropper = (Total CBD inside Bottle) ÷ (Number of Millilitres in Bottle)

For instance, if you have a 30ml CBD tincture that has 1500mg of CBD, 50mg of CBD per dropper = 1500 ÷ 30

The result is 50 mg. If your CBD dosage is 25mg, you can use half of the dropper.

Although this method is not always 100 percent accurate, it is better than not measuring at all.

Measuring CBD Dosage in a Vape

Another popular method of ingesting CBD is vaping (from the word “vaporize”). Vaping is preferred by many because its effects are almost instantaneous when compared with other forms of ingesting CBD. They are so effective because the vapour goes straight into the bloodstream.

Vaping comes in various types. Disposable CBD Vape Pens are the easiest to use as they come pre-packaged and what is needed is to put them in the mouth and throw away when through. Some come with batteries, and some don’t.

A significant advantage with disposable CBD vape pens is that they come with labels that state clearly their CBD content.

Refillable Vape Pen has the power that it can be used for a longer time than disposable CBD Vape Pens. It might also be cheaper in the long run.

CBD Vape Juice Cartridge is another option in vaping. The have pre-filled tanks which are replaceable.

A vaping system consists of a mouthpiece, a chamber that will be used to store the CBD, an atomizer that will be used to vaporize the CBD and a battery.

Measuring CBD in a vaping system is similar to that of a tincture. Here, the emphasis will be on the chamber or tank that holds the CBD. You need to know the capacity of the tank holding the oil.

The vape will come with details of the concentration of the CBD in the tank. For example, CALM CBD Vape Pod Starter Kit comes with a label stating that it contains 1000 mg 5% POD.

To calculate the amount of CBD in this starter kit, simply multiply 1000 mg by 5%. This will give us 50 mg CBD content. So, if your CBD requirement is around that range, this starter pack will be ideal for you.

Let us take another product. CALM CBD VAPE POD CARTRIDGES contains 1000 mg 20% CBD. Using the same approach above, we can calculate the CBD to give us 1000 mg multiplied by 20% which will give us 200 mg CBD content.

So, for PURE Spectrum bubble gum Honey oil (450 mg) 22% CBD Vape Kit set, we have a CBD content of 99% (using the above formula).

Measuring CBD in Percentages

In most cases, you will see CBD measured in mg per dosage. However, you can convert this measurement to percentages. 1000 mg makes up a gram, so if you have CBD oil with 30% label, it means that the oil contains 300 mg out of every 1000 mg of the oil.

Let us assume that you have a bottle of CBD oil with 30ml content. If the oil contains 300 mg of CBD, one can calculate the percentage CBD.

A 30ml CBD oil will weigh approximately 28,000 mg, therefore, to find the percentage CBD, use the formula: [300 mg/28,000 mg]* 100%

This will give us a result of 1.07%. The implication of this is that the CBD makes up approximately 1% of the total oil content.

You Can Ingest in CBD Capsules

CBD capsules contain measured amounts of CBD. Each CBD capsule will be measured at mg/capsule. So, if your dosage is 50mg, all you need to do is to take two capsules of a 25mg/capsule CBD. This method is more accurate and more reliable than the other ways we have described above.

The use of CBD capsules is a better way to calculate your CBD intake. CBD capsules are filled with a specific amount of CBD and because of this, it is a more accurate way to measure your CBD.

Capsules come in standard sizes and can contain a certain limit of CBD. This way the number of capsules you take per day define the dose that you take. Usually, CBD bottles come with instructions about dosing on CBD capsules.

You Can Use CBD Oral Applicators

Using oral applicators is another way to get a serving of exact dosage of CBD. Oral applicators are pure CBD oil-based products that contain high levels of CBD per application. The applicators are produced in 3 and 10-gram tubes and a plunger system for discharging the oils. The side of the tube is calibrated in such a way that the user can easily measure the dosage.

You Can Use CBD Edibles

CBD gummies and other edibles are available in various dosages and flavours. The edibles also come with a defined amount of CBD per serving. Once, you know your dosage, you can ingest the amount of CBD edibles that meet your requirements.

Important Things To Consider When Calculating Your CBD Dosage

  • CBD Bioavailability

Any substance that we take into our body goes through a series of metabolic processes before it reaches the bloodstream, from where it can get to the target site.

In this process, the active ingredient of substance is reduced to a very small amount. Substances going through extensive first-pass metabolism have very less bioavailability.

For CBD to have increased bioavailability, it is important to divert it from first-pass metabolism which makes vaping the best option. But, taking capsules and other methods are also effective, for as long as the quality of CBD not compromised.

This brings us to an important notice i.e. to always check the concentration of CBD in a product instead of looking for the quantity or low price.

  • CBD Overdosing

Overdosing means taking any substance in excess and then experiencing side effects which can be minor like a skin rash or major like respiratory depression leading to coma and death.

As with Marijuana and other narcotics, people usually worry about CBD too.

What if one takes too much of CBD? Will they experience major side effects?

Fortunately, no research studies show that CBD overdosing can result in respiratory depression. CBD is not a drug, it is a fantastic health supplement.

What matters is that you buy it from a trusted vendor to ensure that your CBD contains no additives.

A high dose refers to taking 50,000 ml of CBD. That would be about 300 ml for every 2.5 pounds of body weight. Sensibly, there is no reason for anyone to take that much.

A 180-pound male only needs to take about 25ml to feel relief from his symptoms. That is certainly a long way from 50,000 ml.

  • CBD Biphasic Effect

CBD has a biphasic effect. This means that as dosage increases or decreases, observed effects might defer. For example, taking one or two bottles of alcohol might make you feel good but after a certain threshold (varies for individuals), it might have undesirable effects.

While it is not likely that you will overdose on CBD, it is also important that you take dosages that are within safe limits based on the peculiarities of your system.


A website (https://cbddosagecalculator.com/) has come up with a brilliant idea of how to calculate CBD dosage.

For you to use the application, you have to state the purpose of use (e.g. anxiety, arthritis, dementia etc).

You also need to indicate the severity of the ailment (light, medium or severe). Other information such as body weight in pounds and the total size of your bottle will be required.

For an adult weighing 200 pounds with severe anxiety, the calculator prescribed 22 mg of CBD in week 1, 44 mg of CBD in week 2, and 67 mg of CBD in week 3 and subsequently.

An adult weighing 200 pounds with a medium case of dementia, can take 18 mg of CBD in the first week, 36 mg of CBD in week 2, and 54 mg of CBD in week 3 and subsequent weeks.

The website strongly encourages users to consult with their doctors before using the calculated dosages.

There are other dosage calculators such as “ iDWeeds % to mg Calculator “ and “ iDweeds drops calculator”(see https://idweeds.com/cbd-dosage-calculator/).

If the CBD oil comes with a label indicating the CBD content in mg, you don’t need the iDWeeds % to mg Calculator, you just use the iDWeeds drops calculator to calculate the mg of CBD per drop of oil.

But if the CBD bottle just indicated the percentage CBD, you will need to first convert the % CBD to mg before proceeding to calculate the mg per drop.

The iDWeeds % to mg Calculator converts the amount of CBD to milligrams which can be better appreciated by the CBD user.

The calculator will request for the following: the CBD % and bottle size(in ml). For example, a 30 ml bottle of oil containing 10% CBD is calculated to contain 3000 mg of CBD.

The calculator will then proceed to calculate the amount of CBD in a drop of oil. For the above example, the calculator determined the amount of CBD in a drop to be 25 mg. In this scenario, someone who needs 100 mg of CBD will have to take 4 drops of oil to meet up with the required dosage.
