How to Read CBD Oil Labels to get the most from your product
Currently the cannabidiol (CBD) industry is pretty much self-regulated and under the control of the U.S. Food & Drug Administration. Because of this, CBD oil labelling across different brands and products tend to be inconsistent, often leaving both novice and experienced consumers confused.
However, with CBD considered a “dietary supplement” that has to adhere to certain labelling requirements, there are key elements that, when knowing how to read it, can be useful in helping to decipher what is in a product and how to use it.
Here we go over these elements, teaching you how to read CBD Oil Labels so you can get the most from your product and do so safely.
Key Elements on CBD Oil Labels Explained
CBD oil bottles are generally available in 15 ml, 30 ml and 100 ml bottles which will help determine the amount of CBD per milliliter, an important indicator of CBD concentration/strength/potency.
Every bottle must have an ingredients list. Sometimes this includes only active compounds, however more often than not also a list of “other/inactive” ingredients as well. In the case of CBD oil, this can include the carrier oil and other additives such as flavorings, colorings and sweeteners.
Full Spectrum, Broad Spectrum or Isolate
The label should also indicate the type of CBD the product contains.
Includes a wide range of terpenes and other cannabinoids in addition to CBD and in some THC ( Total milligrams of CBD in the bottle divide by bottle size in ml = CBD mg / ml
For example: If you have a 30 ml bottle containing 1,500 mg of CBD 1,500 ÷ 30 = 50 mg of CBD per 1 ml
However, CBD oil labels often only shows the percentage of CBD in which case the percentage needs to be converted into milligrams first.
Formula: 1 milliliter = 1 gram = 1000 milligrams of CBD oil.
So, if you have a 30 ml bottle of CBD with a concentration of 15% CBD 15% of 3,000 mg = 1.5 x 3,000 = 4,500 mg of CBD per bottle 4,500 ÷ 30 = 150 mg of CBD per 1 ml
Occasionally, as in the case with the popular brand Charlotte’s Web (see graphic), a product will not indicate the amount of hemp extract and not the amount of CBD. This requires the consumer to convert milligrams of hemp extract into milligrams of CBD to get dosage which can be tricky.
Depending on the type of extract, this can either refer to the total cannabinoid content, or it could be a direct substitute for CBD.
If it’s the total cannabinoid content: The CBD amount will be less than the labelled amount for example, 1,000 mg hemp extract may only contain 700 mg of CBD.
If it’s a direct substitute: The CBD amount will be the same as the labelled amount for example, 1,000 mg of hemp extract will contain 1,000 mg of CBD.
To find out which it is, check the third party lab tests for the product or reach out to the company directly.
Additional Useful Information Explained
Third Party Lab Testing
Although not required, if a CBD company is willing to invest in third-party lab testing and be transparent about their products and their contents, it can be reassuring when making a purchase.
Carbon Dioxide (CO2) Extraction
Uses supercritical carbon dioxide to separate the CBD extract and other compounds from the plant material and considered the “cleanest” and safest extraction method.
Uses a hydrocarbon or natural solvent to dissolve the CBD extract and other compounds from the plant material but in the case of hydrocarbons can leave behind toxic residues in poorer quality oils.
Do Bigger Numbers Mean It’s Better?
It is a common misconception that more means more, however a bottle with a high CBD content is not always “stronger” than one with fewer milligrams. For example, a 30 ml bottle of 1,000 mg CBD has the same potency as a 15 ml bottle of 500 mg CBD at 33.3 milligrams of CBD per milliliter.
How To Calculate Price / Milligram
To calculate the price per milligram of CBD is simple.
Product Price / CBD Content in MG = Price Per Milligram of CBD Content
A 30 mg bottle containing 1,500 mg of CBD for €79,95
€79,95 / 1,500 mg = €0,05 per milligram of CBD content
While the CBD industry is largely unregulated, there are certain labelling requirements that must be included on CBD oil labels from legitimate brands, and include:
- the number of milligrams or percentage of CBD in the bottle
- the bottle size
- the recommended serving size
- the ingredients as well as;
- a batch number
With this information, you can be assured that your CBD oil is not only legitimate and safe to use, but will also help you to use it properly so you can get the maximum benefits from your investment.

Converting potency from mg/g to %
Since we went live in October 2018, many customers have become familiar with flower potencies being listed as percentage values.
With the revised regulations, all new categories must display the potency/concentration in milligrams per gram (mg/g) or total quantity in milligrams (mg), depending on the class of cannabis and immediate container. Another label change to note is that cannabis oil sprays (and any cannabis extract in a container with an integrated dispensing mechanism) will display the total THC & CBD per activation in milligrams. Oils will change from mg/ml to mg/g – a basic conversion is nearly one to one (the determined density of grams to volume is 0.93 g/ml).
Existing categories (dried flower, oils and capsules) have been given a 12-month grace period to allow suppliers time to transition to comply with new labelling requirements, so customers should expect some variation and exceptions during this time.
What does this mean for customers?
Flower and pre-roll products will be the biggest change, but the conversion method from mg/g to % is easy once known:
Simply move the decimal point one spot to the left to figure out the percentage of THC or CBD.
For example, if the flower is listed as 200mg/g of THC then it will contain 20% THC. Here’s how the formula works: There are 1000mg in a gram, so first we divide the mg/g and then we multiply it by 100 to get a percentage:
200mg/1000mg (1g) = 0.20
For reference, here are some common potencies in both mg/g and their % equivalent:
All products will feature their net weight in grams, with the exception of beverages, where the volume must be represented in milligrams.
