Does CBD come in different strengths?


CBD Oil – This comes in different strengths, providing different potencies.


Milligram strengths


Low Potency CBD Oil (300mg) – This is fairly low potency oil and is a good option for those who are just starting out or who may be sensitive to CBD (and/or cannabis in general). A low-strength 300 mg bottle is a good option to take as a daily supplement. Many people take a single daily dose of it for boosted general health, and also to help lower stress levels.

Mid Potency CBD Oil (600mg) –  A 600mg oil is a good “step-up” option for people who find they’re having to take large and/or multiple doses of a lower potency. In general, a lot of people use products in this strength range for things like anxiety and day to day pain. A single dose would still be defined as 20 drops (1mL) of oil, but instead of containing 10 mg of CBD, a 600 mg bottle would contain 20 mg per serving.

High Potency CBD Oil (1,000mg) – The 1,000mg range is on the upper end of the potency scale for most CBD oil’s. Products in this strength range are commonly used for sleep problems, deep muscle soreness, migraines, and day to day stress and anxiety.

Just like the 300mg and 600mg products, most 1,000mg hemp oils come in a 30ml bottle. A single 20 drop serving equates to a CBD dose of approximately 33.3mg. In most instances, users won’t have much use for a higher strength product than this. 

The main thing to consider when working out out how to find the right strength CBD oil is to realize that everyone’s internal biochemistry is different. While your friend may be able to ease his/her stress with just a single 3mg serving, you may require several times that much in order to obtain the same results. Or, you may not find any relief at all. This is why it’s important to start with the smallest possible dose and work up from there.

The milligrams do not tell the whole story of the strength, this is also displayed in a percentage - This is the percenatage of the CBD present in each bottle.




The milligram figure is not the true strength alone, especially if you measure your doses by number of drops. Most people measure doses in drops (or droppers) so understanding what the true strength of the CBD product you use is really important. This is because there’s something else that must be taken into account – the volume of the product container. There are a range of typical bottle sizes that CBD oil is sold in – 10ml, 30ml, 60ml, even 100ml.

So knowing the volume of the bottle is crucial too


 If you have a 10ml bottle of CBD Oil which has 1000mg stated on the label, and a 20ml bottle that is also stated as 1000mg, then these two bottles actually have different strengths despite containing the same amount of CBD. Drop for drop the 20ml bottle is only half as strong as the 10ml bottle. Yet they both contain the same overall amount of CBD, but if you measure your dose in drops like most of us, then you’re only getting half the amount of CBD when using 5 drops of the 20ml product versus 5 drops of the 10ml size.

In other words, the same amount of CBD has been diluted into a much larger volume of carrier oil, so each drop contains less.


Percentage strengths 


This is probably the best measure of strength regarding CBD Oil. The percentage given on the label represents the concentration. i.e. the true measure of the drop for drop strength of a product.

For Example - 1000mg of CBD in a 10ml bottle has a concentration of 10%.

Therefore, 1000mg in a 20ml bottle has a 5% concentration – So drop for drop it’s only half as strong as the 10% oil despite containing the same 1000mg amount of CBD.

Another example – If the label gives the figures “2.75%” and “275mg CBD per 10ml” – The entire 10ml bottle contains 275mg CBD and therefore the concentration of CBD within the carrier oil is 2.75%.

The percentage concentration is actually more important than the total overall milligrams in assessing the strength of a CBD product.

2000mg sounds like a very strong CBD product right? Well yes it is if it’s in a 10ml bottle, but not so much if it’s in a 100ml bottle! The former is 20% strength and the latter is just 2% strength.

What is Full Spectrum – Broad Spectrum and CBD Isolate?

These are terms that you will find quite often regarding CBD products, here we explain exactly what they are, and which ones are best suited to your style of CBD use.

All CBD products are extracted from the cannabis plant, using solvents like CO2. During the extraction, all the cannabinoids, terpenes, and flavonoids are stripped from the plant and disolved in oil to make it easier to administer and store. Depending on the cannabis strain used for the process, the cannabinoid profile of your CBD oil will differ.

Full Spectrum CBD – Also known as Whole Plant Extract contains all phytochemicals naturally found in the plant, including CBD, trace cannabinoids, terpenes, and essential oils. Full-spectrum extracts from hemp also come with a negligible THC content —  below 0.2%. The full spectrum of the active compounds extracted from hemp work together to amplify the health benefits of each individual cannabinoid, each cannabinoid offers different benefits for a broad range of conditions. However, it’s worth noting that CBD offers (almost all of) the same benefits as all of the other cannabinoids combined. So, if this is the case, why would Full Spectrum be any more effective than CBD Isolate?

The answer lies in the ‘Entourage Effect’.

Broad Spectrum CBD – Put simply Broad Spectrum CBD contains cannabidiol and all the other compounds within the plant, save for THC, which is completely removed after the initial extraction, bridging the gap between full spectrum and isolate CBD: it's processed like isolate, yet offers a wide array cannabinoids like full spectrum. As Broad Spectrum extracts contain multiple cannabinoids, they also produce the “entourage effect,” but without the THC. In a very simplified manner, Broad Spectrum CBD is like a mix between Full Spectrum CBD and CBD isolate. It contains the entire spectrum of cannabinoids except for the THC part.

Put simply, Broad Spectrum CBD is Full Spectrum CBD, with the THC removed

Isolate CBD – Known as the purest form of CBD, but conversely, it's the most processed form of hemp plant of the cannabis sativa family. Hemp contains much higher amounts of CBD than other plants in the cannabis genus, such as marijuana which is mainly grown for it’s THC rich buds. Isolate CBD is CBD isolated from all other parts of the hemp plant including terpenes, cannabinoids, and essential oils until there it is the only cannabinoid. CBD devotees & experts alike agree that a CBD isolate will provide the benefits of CBD, but is missing the cannabinoids that make full spectrum & broad spectrum a potentially, more powerful approach. 

The CBD is purified upon extraction, and Isolated from the other cannabinoid compounds.

Entourage Effect – The phenomenon known as the entourage effect occurs when the many natural compounds of a plant interact together within the human body to produce a stronger impact than any single compound used in isolation. Broad spectrum CBD is wonderful for those who want to experience the entourage effectThis therapeutic effect can only take place when the wide variety of cannabinoids within hemp are working together to maximize the most therapeutic benefits. Even though the individual compounds may in fact share the same beneficial uses, the entourage effect means that the results are multiplied. In this sense, whole plant CBD truly epitomises Aristotle’s famous phrase ‘the whole is greater than the sum of its parts’.

The entourage effect takes place in both Full Spectrum and Broad Spectrum CBD, and does not take place in Isolate CBD. 

So which one should I choose?

The choice is of course yours, but here is a round up to guide you.

Full Spectrum CBD – These CBD products will contain some THC which is the psychoactive cannabinoid within the marijuana plant, which in the UK is classifies as a Class B controlled drug. Full Spectrum CBD contains only trace amounts of THC and must by law not exceed 0.2% threshold. 

Broad Spectrum CBD – These CBD products DO NOT contain and THC compound, it has very similar properties as the Full Spectrum but without the psychoactive ingredient, THC.

Isolate CBD – The CBD is purified upon extraction, and isolated from the other cannabinoid compounds, it does not contain THC. CBD devotees & experts alike agree that a CBD isolate will provide the benefits of CBD, but is missing the cannabinoids that make full spectrum & broad spectrum a potentially, more powerful approach.
