this calculator is for informational purposes only. Talk with your Doctor before taking CBD. Individual results vary, and in fact it is already known that individuals have wildly different results with CBD.

What is the optimal CBD dose for you?

There are a couple of things you should know before starting to crunch numbers. Firstly, there is no general dose that is considered ”normal” for people of any age. Some people start with just 1mg daily, while others use up to 100mg every day. Finding what works for you takes some trial and error, but you are all set for success once you do. 

Consequently, we suggest you start with the lowest dose you believe is right for you and then increase the amount until you achieve the optimal dose for your body. Don’t give up too soon, as CBD oil’s effectiveness heavily depends on finding that sweet spot that clicks with your endocannabinoid system, and this can take some patience and persistence.

Keep on reading as we get into how to calculate your first dose based on your weight.

How to calculate your CBD dose based on your weight

The main two variables when calculating CBD dosing are weight and the potency of the selected CBD isolate product. What is important to mention first and foremost is that the CBD dosage chart below and the calculations we use are based on pure CBD content, not oil quantity. So if you grab your bottle, you will see it contains a certain amount of oil, but the CBD content is also marked clearly. When combining two variables (CBD content and weight), we can define the strength of the dose you want to take. Let’s have a look:

Your weight (lbs)

Low strengthMedium strengthHigh strength
100lbs10mg30mg60mg
125lbs13mg38mg75mg
150lbs15mg45mg90mg
175lbs17mg52mg105mg
200lbs20mg60mg120mg
225lbs22mg67mg135mg
250lbs25mg75mg150mg

So, if you want to take a low strength dose, you will be taking 1 mg of CBD per 10 pounds of your weight. If you decide to take a medium-strength dose, you should be taking 3 mg of CBD per 10 pounds of your weight. Finally, if you opt for a high strength dose, the appropriate amount will be 6mg per 10 pounds of your weight. 

Keep in mind that this CBD dosage chart is just a guideline, and the dose you choose can be lower or higher than the one stated in the table, depending on recommendations of your doctor.

If you are still not sure, we have more information coming and a handy CBD dosage calculator. As you already know, many people use CBD oil to deal with various medical conditions. While CBD is not yet classified as a medicine and it is not FDA approved, it has been used to alleviate aches, pains, and bad feelings for decades. This is why we can make an educated assumption on the appropriate strength for each condition:

  • Alzheimer’s disease – medium strength
  • Arthritis– medium to high strength
  • Multiple sclerosis – medium to high strength
  • Chronic pain – medium to high strength
  • Cancer – high strength
  • Epilepsy – high strength

How do you find your optimal CBD dosage?

Assuming you are playing it safe and starting with the lowest strength, you should take 1 mg of CBD per 10 pounds of your weight. This means that if you are a 130 lbs person, your first dose should be in the realm of 13mg. There’s no need to pay attention to nano milliliters of substance, which makes dose calculations easier to comprehend. 

If you already have experience with CBD oil, you might want to go for the medium strength, which would be 3 mg per 10 pounds of your weight. Again, for a 130 lbs person, this will be 39 mg. When striving for the most potent dose, you should go for 6mg per 10 pounds of weight, which is 78 mg. 

You have probably got the enhanced gist by now, but when in doubt, don’t hesitate to use our CBD calculator just to be sure. 

  • What is the CBD dosage for the most common conditions?

    In case you want to use CBD to free yourself from a particular condition, you might've heard about different doses from different sources. While there is no definite CBD oil dosage calculator for any disease, we have gathered some useful information for you to make an educated choice.

  • CBD dosage for Alzheimer's disease

    CBD oil has been shown to reduce and alleviate the effects of inflammation, which is one of a few things that enhance the adverse effects of Alzheimer’s. Not only that, CBD has also been shown to reduce agitation in patients with Alzheimers. It is recommended to start with 20 to 40 mg of CBD oil a day, possibly portioned through the day. If handled well and without side effects, you can increase the dose.

  • CBD dosage for Arthritis

    Researchers had found a significant improvement in inflammation and pain when using CBD to treat arthritis in rats. Twenty to 30mg of CBD oil should be an excellent dose to start when trying to manage arthritic pain. Increase the dose gradually if you experience no side effects and the pain is still present.

  • CBD dosage for Multiple sclerosis

    The reason why a person with MS would use CBD oil is spasms. Muscle spasms are one of the signature symptoms of multiple sclerosis. During studies, many people reported a reduction of symptoms after using CBD. You can start with 14mg daily and increase the dose if needed.

  • CBD dosage for Chronic Pain

    There is substantial evidence CBD can reduce pain and inflammation. For chronic pain, an appropriate dose to start with would be somewhere between 20 and 40mg a day.

  • CBD dosage for Cancer

    CBD oil doses for patients with cancer start at 40mg per day. It is essential to mention that there is no evidence whether CBD or any other hemp product can cure cancer. Still, it can alleviate symptoms of cancer and side effects that are a result of cancer treatment.

  • CBD dosage for Epilepsy

    CBD has been shown to help alleviate seizures in people with epilepsy. The doses used were pretty high, around 70mg of CBD oil daily, but you can always opt for a lower amount and increase it gradually.

    These instructions should in no way be a replacement for an appropriate diagnosis and treatment plan decided upon with your doctor. Please consult your doctor before using any medications or supplements, especially if you have a chronic disease and are already using other prescription medicines.

How to Calculate the Potency of CBD Oil Drops

Before using CBD oil dosage calculator, you should be aware of how potent your CBD oil is. It is easily determined by dividing the milligrams of CBD in the bottle by the bottle’s total milliliter content. For example, if you bought a 40ml bottle of CBD oil with 700mg of CBD in the bottle, divide 700 by 40. Thus, your CBD oil contains 17.5 milligrams of CBD in every milliliter of oil.

How to Measure CBD Oil Drops

Some products specify how much CBD there is in each drop. If this information is not there, here is a way to calculate how much CBD there is in each drop and consequently, how many drops you should take.

A rule of thumb is that a single drop contains 0.05 milliliters of liquid.

If we use the same 40ml bottle we mentioned before, we now know it contains 800 drops.

Since the package indicates that the oil contains 700mg of CBD, this means each drop will have 1.14 mg of CBD. You only need to divide the CBD content by the number of drops in the bottle.

If you are just starting using CBD, you might be opting for a lower, 15mg dose. To achieve that, you will have to use 17.5 drops of this particular CBD oil.

Final thoughts

We hope this article will offer you guidance when deciding on the best way to go with dosing CBD oil and supplements. This is a good time to reiterate that every person is different, and there is no exact CBD oil dosage calculator that guarantees success. The good news is that even if you take too much CBD without knowing your limit, the side effects are well known, mild and temporary. If you experience any nausea, low blood pressure, dizziness, sluggishness after your CBD oil dose, you might’ve taken a dose that is too strong for you, meaning you should dial it down next time. With patience and persistence you will most likely find your perfect dose, and the whole CBD consumption process will be worth it.
