When you’re choosing a CBD oil, strength is one of the key factors you’ll need to consider. Strength refers to the cannabidiol, or CBD, content of the product; the stronger the CBD oil, the less oil you’ll need to achieve the desired effect.
In this article, we’ve gathered together our five of the UK’s best high-strength CBD oils. Before we dive in, though, let’s discuss what exactly constitutes a max-strength oil, why it matters, and how to make sure you’re getting your money’s worth.
How can I tell the strength of a CBD oil?
The CBD content of a CBD oil is displayed on the package in micrograms (mg). However, choosing a high-strength CBD oil is not quite as straightforward as simply choosing the bottle with the highest number.
If a CBD oil is listed as 2000mg, then there are 2000 micrograms (mg) of CBD in the entire bottle. To get an accurate picture of strength, you also need to know the CBD content per individual serving.
Here’s why that matters…
A 10ml bottle and a 20ml bottle of 2000mg CBD oil both contain exactly the same amount of actual CBD. But if you take a 1ml serving from the 10ml bottle, you’ll get 200mg of CBD, while if you take the same 1ml serving from the 20ml bottle, you’ll only get 100mg of CBD.
For clarity, we list the specific mg per serving in the description for each product on CBD Shopy so that you can see exactly how much CBD you’re getting.
What do the percentages mean?
You’ll sometimes see a percentage too, which represents the concentration of CBD in the product in relation to the entire bottle. This is a more reliable indicator of strength, but not all brands use it. If you want to work it out for yourself, you can use the following formula:
Total CBD content (mg) / bottle volume (ml) / 10
Here’s an illustration…
Bottle A is 10ml and contains 4000mg of CBD. So:
4000mg / 10ml = 400
400 / 10 = 40%
Bottle B is 20ml and also contains 4000mg of CBD. So:
4000mg / 20ml = 200
200 / 10 = 20%
Bottle C is 10ml and contains 2000mg of CBD. So:
2000mg / 10ml = 200
200 / 10 = 20%
Based on these calculations, you can see how Bottle A is twice as strong as Bottle B, despite containing the same amount of CBD. You can also see how Bottle B and Bottle C are equal strengths, despite Bottle C containing half the amount of total CBD.
What strength CBD oil should I use?
The products featured in this article are some of the strongest CBD oils available in the UK. If you’re new to CBD oil, we recommend starting with a very low-strength product until you know how CBD oil affects you, and then building up very slowly to max-strength CBD oils like these.
Even if you’re an experienced CBD user and you’re comfortable with your tolerance, it’s still a good idea to take the following factors into consideration when upgrading to super-strength CBD oil.
Have you noticed how men and women have different recommendations for alcohol intake? Or how one of your friends can put away six pints without blinking but another gets drunk at the mention of wine? That’s because general differences in body size, composition and metabolism all impact how alcohol affects us.
The same applies to CBD. It’s impossible to predict how an individual will react to any given amount, so it’s always wise to work your way up to ultra-high doses in small increments, gradually upping your dose until you achieve the desired strength.
As well as oil, CBD is available in capsule, lotion, edible or vape form. Like CBD oil, these different variations will feature the strength in mg. However, the actual bioavailability of each type varies.
Bioavailability refers to the amount of a substance that is absorbed into the bloodstream and used by the body. CBD oil is absorbed directly into the bloodstream via the blood vessels under your tongue, so the bioavailability is high (85-94%). On the other hand, capsules and edibles have to pass through your digestive system and liver first, so their bioavailability is very low (6-15%).
What does this mean in terms of strength? Well, if you’ve been using extra-strong capsules or edibles, take into account that an oil of the same strength will actually provide your body with a much higher usable amount of CBD. Even if you’ve tolerated the capsules very well, you might want to switch to a slightly lower-strength CBD oil and build up if needed.
It’s always best to take the lowest dose you need to get the desired effect. Not only can you build a tolerance to CBD over time, but high doses can interfere with liver enzyme function and affect your ability to metabolise certain medications.
With that in mind, consider your reasons for taking CBD oil in the first place. If you’re simply looking for a wellbeing boost, a standard dose is likely sufficient. However, if you’re looking for a specific outcome, a high-strength CBD oil can maximise the effects.
WARNING: Always check the lab report!
We’ve broken down what strength means when it comes to CBD oil and explained how to figure out the actual strength of a product. However, this info means nothing if the numbers on the packaging are incorrect.
A recent report found that an alarming number of UK brands were misrepresenting the CBD content of their products. Over a third of the products tested didn’t even contain 50% of the advertised CBD, and one £90 high-street CBD oil contained zero!
UK regulations have yet to crack down on this issue, so for now it’s up to you as the consumer to do your due diligence. Fortunately, you can do this by simply checking the third-party lab report, which will tell you the exact amounts of everything in the bottle, including CBD.
No lab report? At CBD Shopy, we only stock CBD oils that have been tested and verified by independent third-party labs, and we make the reports readily available to our customers. If a brand hasn’t had their product third-party tested or they don’t make the report available, take it as a red flag and buy elsewhere.
CBD Shopy’s top 5 strongest CBD oils
cbdMD Premium CBD Oil 7,500mg
At the top of the list, cbdMD’s Premium CBD Oil contains a whopping 7500mg of CBD per bottle, or an impressive 250mg of CBD per 1ml serving. (However, as we advised earlier, the company does recommend building up to this high CBD dose gradually until you know how it affects you.)
cbdMD is a US-based company that prides itself on the quality of its domestically sourced hemp. They travelled the world looking for the perfect soil composition and climate, and now they use a unique hybrid, non-GMO farming method to grow some of the finest hemp on the planet.
Available in four different flavours (natural, berry, mint and orange), cbdMD’s super-potent, broad-spectrum CBD oil is loaded with the healthful cannabinoids, terpenes, vitamins and fatty acids of the hemp plant. However, unlike full-spectrum products, it’s completely free of THC.
THC is the cannabinoid responsible for the “high” feeling you get from smoking cannabis. CBD oils sold in the UK legally can’t contain any more than 0.2% THC – far below the amount you’d need to feel any psychoactive effects – but some people prefer to avoid THC altogether, especially with very high-strength CBD oils. If you’re one of them, a broad-spectrum oil like cbdMD Premium CBD Oil may be a good option for you.

CBDistillery THC-Free Pure CBD Oil 5,000mg
Second on our list, CBDistillery’s THC-Free Pure CBD Oil packs a super-potent 5000mg of CBD per 30ml bottle, or 167mg per 1ml serving.
CBDistillery hails from Colorado, the US state leading the CBD and legal cannabis revolution across the pond. As the industry grew, the founders pledged to tackle the overpriced, low-quality CBD products that were saturating the market. Now, they’re known as leading providers of affordable, effective CBD oils made from home-grown, US Hemp Authority-certified, non-GMO hemp.
CBDistillery’s extra-strength oil is a CBD isolate, which means all of the other compounds and plant materials have been removed to leave 99% pure CBD. That includes the THC, with third-party lab reports confirming that the oil contains 0.0% THC.
However, it’s worth noting that you won’t get the “entourage effect” you’d get with broad- and full-spectrum CBD oils, which refers to the amplified benefits of ingesting all of the hemp plant’s compounds together (more on that later!).

Love Hemp CBD Oil 4,000mg
At number three, Love Hemp’s signature CBD oil contains 4,000mg of CBD per bottle. Delivering an enormous 400mg CBD per 1ml dose, that makes Love Hemp CBD Oil the strongest CBD oil on the UK market.
London-based brand Love Hemp takes quality seriously. Their high-strength CBD oil is made from a proprietary combination of US hemp strains, grown according to strict non-GMO standards with zero chemical fertilisers, growth hormones, herbicides, pesticides or additives. The hemp is then processed in a GMP-compliant facility, and every batch of oil is prepared fresh to order.
The brand invests in state-of-the-art technology to guarantee the purity and potency of their CBD oils. That includes high-performance liquid chromatography to test for cannabinoids, and medical-grade CO2 extraction technology for gold-standard processing.
The result is a top-quality, ultra-strength, broad-spectrum CBD oil, packed with beneficial compounds and certified 100% THC-free.

Love CBD Entourage Oil 2,000mg
The only full-spectrum CBD oil to make the list, Love CBD Entourage Oil contains 2,000mg of CBD per bottle. One serving is a 0.16ml spray, which delivers 16mg of CBD.
While not as potent as the other CBD oils on our list, Love CBD’s oil more than makes up for it with the “entourage effect”. Full-spectrum products such as this one contain every single compound found in the hemp plant, including cannabinoids, terpenes, fatty acids, phytonutrients, and various other natural goodies.
It’s thought that together, all of these ingredients are greater than the sum of their parts. That means the healthful benefits of each compound, including CBD, are amplified when taken together, as nature intended. This is popularly known as the entourage effect.
Love CBD has carefully curated different hemp strains from across Europe to create the most effective combination of natural compounds for their Entourage Oil. It’s taken years to perfect what they call “the ultimate cannabis cocktail”, but we believe they’ve hit the mark with their signature CBD oil.
Full-spectrum oils do contain small amounts of THC. Entourage Oil’s lab reports confirm that the THC content is below the legal limit of 0.2%, but it’s worth keeping in mind if you’re trying to avoid THC altogether.
CBD Life Hemp Oil Drops 2,000mg
Last but not least on our list is CBD Life’s 2,000mg Hemp Oil Drops, delivering a very respectable 200mg of CBD per 1ml serving.
This broad-spectrum, high-strength CBD oil features all the beneficial terpenes and cannabinoids we love, minus the THC. However, the main reason we love CBD Life is for its above-and-beyond commitment to elevating the CBD industry.
As we mentioned earlier, regulation around CBD is sorely lacking in the UK. The fact that rogue brands go largely unchecked only worsens the stigma and misinformation already surrounding CBD products, but brands like CBD Life are taking the initiative and bringing transparency and accountability to the industry.
As a founding member of The Cannabis Trades Association UK (CTA UK), CBD Life works with all sectors of the industry to promote gold-standard practices, quality education, practical advice, and sustainability. When you buy from a brand like CBD Life, you know you’re getting a quality, ethically sourced product.
