CBD Dosage Calculator & Chart: How Much Should I Take?

CBD Dosage Calculator & Chart: How Much Should I Take? - NanoCraft


CBD dosing charts can be helpful when it comes to deciding which dosage you’d like to start your CBD regime at. CBD calculators can help you in determining your dosage. As a disclaimer, the information in this article is for educational purposes only. It does not exploit or provide medical advice of any kind. Therefore, any reliance you place on the information below is strictly at your own risk. Please check with your medical provider before starting or changing a CBD routine or dosage.


CBD dosage calculators have been continuously popping up on the internet in hopes to help users estimate and calculate their desired dosage based on information they provide. Though CBD is not yet FDA approved, individuals are heading to the internet to receive more information about  CBD dosing charts and CBD calculators. 

There are three main CBD calculators that users are referring to frequently: CBD dosage by ailment, CBD oil drop dosage, and CBD conversions for dosage. More on this below!



You can use the CBD dosage calculator for the purpose of helping you gauge a CBD dosage, personalized to fit your concerns or ailment(s), for that matter. Again, our CBD products are not intended to treat, diagnose, cure, or prevent any disease, condition, ailment, or concern. 

When using this CBD dosing chart, you must first agree to reading their disclaimers, terms and conditions, then proceed to the survey. 

First, it will ask you if you are looking for CBD for you or your pet (select ‘Human’). Then, it asks your purpose of use (i.e. anxiety, migraines, pain, etc.). It will then ask you if you would like to convert the CBD milligrams to drop amount of mL based on your specific product (you can mark yes or no). 

You can input your tincture bottle’s mg content as well as the content of CBD mg, followed by your weight in pounds (lbs). It will then generate you a “calculated” dosage, in milligrams, of CBD, with the exact number of drops, in milligrams, listed below. 



This CBD calculator is specifically designed to calculate your right dosage based on 3 factors: size of your CBD bottle (i.e. 1000 mL), the total mg of CBD in the bottle (i.e. 500 mg), and your approximate weight (i.e. 140 lbs). 

Once I input that information in, for instance, it provided me with a suggested minimum, average, and maximum dosage per day as well as how many drops the bottle may contain. 

Again, talking with your physician is key prior to taking CBD or starting a specific dosage. Each and every CBD product is not created equal, so there isn’t a one-size-fits-all yet. 


Depending on your CBD oil and bottle, there may be more or less milligrams contained in a single CBD drop. For example, if you're using our CBD Oil Drops Gold Series, it contains 30 mL and 1000 mg of CBD oil, and let’s say you weigh 140 lbs, it’s estimated that your bottle contains ~1380 drops, with about 33 milligrams of CBD per milliliter in the bottle. 

Another example here, if you’re taking our CBD Night Formula, containing 30 mL and 300 mg and you weigh 185 lbs, this calculator estimates that your bottle contains ~1380 drops, with about 10 milligrams of CBD per milliliter in the bottle. 


You can use a CBD tincture oil by using the dropper applicator. By simply opening the CBD oil bottle, squeezing the top of the silicon topper, you can see how many milligrams you are taking based on the measurement lines on the glass dropper. 

Once you have your desired amount of oil in the dropper, you can place the dropper into your mouth, squeeze the silicon topper, and let the oil drip under your tongue. The faster you squeeze the dropper, the faster the drops will come out, and vise versa. 



This dosage calculator accounts your gender, body weight, how often you take CBD, and which method you plan on taking. 

First, it will ask your gender (i.e. male), then your weight (i.e. 200 lbs), how often you take CBD (i.e. 1 x a week), how you plan on taking your CBD (i.e. sublingual), and then it will ask for your name and email to send you your recommendations. FYI, it also shows you your results on the website directly after you press submit. Simple!

It recommended (based on the example information I included above) that I have an intermediate dosage (15 - 30 mg per day), a low dosage (5 - 15 mg per day), or a heavy dosage (30 - 65 mg per day).

In a general sense, I’d say this calculator is more broad compared to the other sites in regards to recommendations. 

For simple conversion factors that these websites do for you, I’ve included them below (in case you were curious for yourself): 

VOLUME (mL - oz) 1 oz - 29.5735 mL

AMOUNT (% - mg) % x mL = mg 

WEIGHT (lbs - kg) 1 kg = 2.20462 lbs



Cannabidiol (CBD) is a compound found in the cannabis plant that is non-psychotropic, it won’t get you “stoned” or “high”. CBD is just one of 100+ cannabinoids located in the cannabis plant, which can be an umbrella term for the hemp and marijuana plants. 

CBD oil can be extracted from both marijuana and hemp plants. When CBD tincture is derived from the hemp plant, there may be 0.0% - 0.3% THC present. CBD oil derived from the marijuana plant may have 0.3% THC or greater present. 


Starting low and slow and a great way to ease yourself into taking the right CBD dosage. You can always increase your dosage as you start to get a feel for taking CBD and what benefits you are looking for. For instance, we recommend starting with half a dropper of our CBD Drops (.50 mL), giving you time to gauge how that dosage may affect you and increasingly accordingly if desired. 

We highly recommend talking with your primary care physician prior to starting any supplements or CBD products. Taking CBD may have an affect or interact with your current medications, so always proceed with caution and professional advice first. 


Factors that can influence your CBD dosage may include:

  • Your size and weight
  • Experience with CBD
  • Metabolism
  • Administration method
  • Frequency of use

The dosage of CBD you take at a given time may also influence how long the cannabinoids stay in your system. If you’re taking large doses at one time, the CBD may take longer to metabolize in your system, thus, it may take longer to leave your system. 

Your metabolism is a key player in regards to how fast CBD can exit your system. Also, if you take your CBD with food compared to on an empty stomach, the metabolic effect may be slightly altered. 


Different methods of CBD will have different effects on your body. For instance, if you smoke or vape CBD, this can take effect almost instantly. On the other hand, if you are ingesting CBD it may have a more delayed effect, since it needs to be metabolized.

If you take CBD tincture oils sublingually, this may metabolize more quickly due to its absorption directly into the bloodstream via your tastebuds, bypassing your digestive system. 

CBD capsules may take longer to be metabolized and absorbed due to the path and process it will take through your digestive system. 

CBD topicals and lotions will absorb differently through the skin compared to other methods. The cream will be absorbed transdermally, seeping into the bloodstream. 


You can’t overdose on CBD. 

A 2017 clinical update published in Cannabis and Cannabinoid Research Journal considered CBD to be generally safe. If you take a large dosage of CBD capsules or any CBD product for that matter, there are potential side effects that may follow. 

Potential side effects may include: 

  • Decreased appetite
  • Diarrhea
  • Fatigue
  • Vomiting
  • Extreme sleepiness
  • Lethargy


CBD may take 1 - 6 hours to work, but this depends on the user’s metabolism, frequency of CBD usage and dosage, type of CBD they’re using, and their size and weight. 

CBD can stay in your system for anywhere from 2 - 7 days, depending on the 4 main factors above. 

How often you use CBD oil will influence the amount of time it can remain in your system. For example, if you infrequently take CBD Oil Drops or CBD Capsules, then it may not stay in your system for as long compared to if you took CBD products everyday.
