What is the strongest CBD Oil in the UK?

Strongest CBD Oils UK

When buying cannabidiol products, it’s not really the CBD that you want, it’s the results! Everyone who buys CBD products has their own reason behind the purchase. Some people want to improve their general well-being and others are looking for a specific outcome.

Whatever the reason for your purchase, you can increase the chance of achieving the result you want by selecting a high-strength oil. The most potent products give you more options and have been linked to a wider range of benefits.

To help you get results, we have carefully chosen a list of the strongest oils, pastes, balms and e-liquids available in the UK. Each one has had to meet our strict criteria and come from a trusted and transparent supplier. Whereas there will be some that may be stronger or equal to those below. We have not yet been able to validate claims or try the product ourselves. Here we give you all the information you need to make your own informed choice.

Why Choose Strong CBD Products?

High-strength CBD products can provide a wider range of benefits than the weaker ones. With a strong item, you can choose between a large serving or diluting a small amount to create a microdose. The versatility of these products makes them the best buys and the most sought-after products available.

1. More Cost-Effective

When you purchase a strong CBD product you will have to spend more. However, in the long run, you are often getting a far better deal because they contain more active ingredients. Buying a large amount of CBD in one single purchase is cheaper than if you buy the same amount in several low-strength bottles.

2. Smaller Servings For Greater Effect

Once you have a strong CBD product you only need to take a very small amount to get the same effect as a large volume of a weaker item. This is great if you are not keen on the taste or want to add it to a meal without giving your food an oily flavour.

3. Larger Amounts For Health Benefits

Many of the studies that have linked the use of CBD to specific health and medical benefits use daily amounts of between 100mg and 900mg. While it would not be a good idea to try and copy this, a higher-strength oil has more chance of providing the result you want.

Why You Need This List!

It is important to get a high-quality product that contains exactly what it says on the label. Recent research commissioned by the Centre for Medical Cannabis selected thirty well-known CBD oils from online and high-street stores. 62% of the products tested didn’t match their labels and one contained no CBD at all.

Quality products from suppliers that have been verified by official industry authorities will be transparent about their farming and manufacturing processes. By choosing them you can be confident that you are buying toxin-free products with the expected concentration.

Using our selection will give you a shortcut to the strongest products that you can trust.

Herb Reviews Selection Criteria

To make sure that we have only chosen the best, most reliable brands and products, we have developed a rigorous selection process. While our choices come from years of industry experience, our guiding criteria are built around three key points:

Certificates of analysis – These are detailed reports provided by third-party labs. They show the actual amounts of cannabinoids and other substances found in the product. They are completed for each batch and should be made available to the customer.

We have only included products with lab reports that verify the safety and accuracy of the latest batch.

Full-spectrum – Full-spectrum CBD products are those that contain other cannabinoids, terpenes or flavonoids alongside the cannabidiol. The presence of small amounts of other substances has been found to interact with receptors in your nervous system altering and enhancing the effect of CBD.

Potency – Although we have chosen the strongest products, we also want them to be potent. This doesn’t just mean a high concentration of CBD. Preparation methods, the hemp strains used, and other ingredients can also enhance the overall effect of each product. We chose the strongest products that provide the biggest results.

Strongest CBD Oils

Oils are the most versatile CBD product. They can be applied in drops, sprayed under your tongue (sublingually), added to food or mixed into your own topical creams and balms. Those that contain concentrations greater than 25% CBD are considered strong but the strongest can reach 40% or more.

CBD Ultra 50%: Strongest CBD Oil

CBD Ultra 50% CBD Oil
How Good Is It?
CBD Ultra’s 50% oil is one of the strongest CBD oils available in the UK today. It’s surprisingly light tasting with 5000mg of CBD suspended in an MCT carrier oil. One bottle provides about 200 drops, each with 25mg of CBD. As well as CBD you also get a full spectrum of cannabinoids and numerous beneficial terpenes. You can get a bottle of this oil for around £225 and it comes in hemp flavour or with added peppermint essence.

It’s entirely natural with no additives or artificial preservatives. The cannabinoids have been extracted from hemp grown to organic standards too. The MCT oil is sourced from coconuts and filtered to contain only the most active medium-chain triglycerides. This gives the oil a buttery taste and provides superior absorption of the active ingredients.

It’s produced from hemp farmed in Colorado, USA; then it’s tested by a third-party lab. The results of the analysis show traces of a broad range of cannabinoids as well as high levels of CBG and CBDVa. CBD Ultra also report that their own internal tests show that there are no heavy metals, pesticides and solvents.

Bud and Tender 40% – Strongest THC Free

Bud & Tender Logo
Bud and Tender 40% CBD Oil
How Good Is It?
This potent oil contains a premium broad-spectrum extract that’s free from THC and has been filtered to improve flavour and clarity. It has a light, floral taste with very little of the usual hemp bitterness. Each 10ml bottle contains 4000mg of CBD in an organic MCT oil carrier. However, you can make a significant saving in the long run by opting for the 30ml option, which packs an impressive 12000mg. Bud & Tender have precisely calibrated the filtration to remove plant debris such as lipids, waxes and chlorophyll but leave the most useful cannabinoids, flavonoids and terpenes.

Every time I’ve used their oils, I’ve been impressed with the potency, flavour and attention to detail. Not only do you get an excellent oil, but you also get additional features such as a handy measurement scale on the pipette and a leakproof child-safe cap.

The hemp is sourced from ‘top shelf’ suppliers worldwide and brought to the UK for manufacture. The lab reports provide exceptional detail and include a detailed screening for contaminants, a terpene profile and a cannabinoid profile. They confirm the presence of several cannabinoids including CBG, CBC, CBT and CBDV, and that no THC was detected.

Cibdol 30% and 40% CBD Oil

Cibdol Logo
Cibdol CBD Oil
How good is it?

Cibdol 40% CBD oil contains a full-spectrum extract suspended in MCT oil. In one 10ml bottle, you get a total of 4000mg of CO2 extracted CBD. If you prefer, you can opt for their 30% version, which comes with a slightly less potent 3000mg CBD. Both have been carefully filtered to leave only the cannabinoids, terpenes and fatty acids.

I was impressed by the sparkling appearance and rich amber colour of this oil. The flavour is pleasantly floral with a relatively intense hemp-like aftertaste. Using Cibdol oil three to four times a day improved my focus and helped me to feel relaxed. It also helped me fall asleep at night and made a noticeable difference in the quality of my sleep.

The third-party lab results are completed by the Dutch lab Brightlands and can be accessed via a link on the product page. The certificate shows that the oil contains the amount of CBD advertised on the label. It also reports that several other cannabinoids were detected, proving that it is a full-spectrum product.

CBD oil Information – CBD content: 4000mg or 3000mg CBD per 10ml.

Nordic Oil 30% and 40% CBD Oil

Nordic Oil CBD Oil
How good is it?

Nordic Oil offers two high-strength CBD oils; you can choose from 30% or 40%. They both come in 10ml bottles and blend a potent full-spectrum extract with a high-quality MCT carrier. The hemp has been extracted using supercritical CO2 to achieve the ideal balance of cannabinoids, terpenes and other beneficial plant substances.

The flavour provides hints of grass and walnuts with a slight bitterness that doesn’t get too intense. After a few days of using this oil regularly, I felt relaxed and saw an improvement in my anxiety symptoms. It also took the edge off my tension headaches but didn’t remove them completely.

Nordic Oil commissions third-party lab tests for all its products. Only a few are published on their website, but they encourage you to contact them if you want to see any specific documents. The lab results I could find were conducted by R & D labs and included a profile of 8 cannabinoids.

CBD oil Information – CBD content: 4000mg or 3000mg CBD per 10ml.

25% CBD Oil by CannabiGold
How Good Is It?
This premium amber coloured oil contains 3000mg of CBD in 10ml. It comes in a spray bottle that delivers approximately 100 pumps, with each pump delivering 30mg of CBD. The spray allows for easier application as it can be aimed under your tongue to take it sublingually. It is priced at £219.90.

Unlike many high strength oils, this one has a pleasant nutty flavour instead of the intense bitterness that often comes with strong full-spectrum oils. The certificates of analysis show a full range of cannabinoids including CBDV, CBC and CBG. The terpene β-caryophyllene is also present.

Most CBD Per Bottle

Although strong products are generally considered to be those with a high concentration of CBD, it’s also worth considering those with a large amount per container. These may not be as strong per drop, but you get more actual cannabinoids in a single purchase.

Love Hemp 10,000mg CBD Oil

Love Hemp Logo
Love Hemp 10000mg CBD Oil
How good is it?

This 10000mg CBD oil from Love Hemp comes in a 100ml bottle. It has a concentration of 10% and contains a broad-spectrum extract (THC-free). The cannabinoids come from US-grown hemp and are suspended in organic MCT oil. This adds a buttery flavour to it and speeds up absorption.

The oil is almost completely clear and has a pleasantly mild flavour with a hint of hemp and a touch of something spicy. When I held it under my tongue, I didn’t notice any flavour at all, so it’s ideal if you’re not keen on CBD oils that are intensely bitter. I experienced relatively mild effects that built up slowly over the course of a few days. It reduced my anxiety and increased my ability to stay focused and alert during the day.

Love Hemp’s oil is made with all-natural ingredients and the hemp is grown by well-known organically certified grower Folium Biosciences. The oil comes with a batch number on the bottle and you can use it to search for the relevant third-party lab results. The results I looked at only detected CBD and CBDV, but Love Hemp reassured me that the original concentrated extract showed a broad range of cannabinoids but that they became harder to detect when they diluted them in oil.

CBD oil Information – CBD content: 10000mg CBD per 100ml.

Strongest CBD E-liquid UK

Vaping is a great way to take CBD because 56% of it can reach your bloodstream to be used in your body. When you place CBD drops under your tongue between 12% and 35% reaches your bloodstream. This means that vaping is one of the most efficient and cost-effective ways to take CBD.

Also, because they are highly effective at lower doses, there are very few high strength e-liquids available. To get around this you can boost the concentration of cannabinoids with an e-liquid additive.

CBD Ultra 10% CBD Vape Juice

CBD Ultra 10% E-Liquid
How Good Is It?
With an incredible 1000mg in 10ml, this high-strength range of e-liquids from CBD Ultra is the strongest full-spectrum e-liquid we’ve found in the UK. What’s particularly special is that it’s made with fractionated coconut oil and contains no propylene glycol (PG) or vegetable glycerin (VG). As a result, it can double up as oral drops as well as being vaped and inhaled.

Each e-liquid is made with a high-quality, full-spectrum extract from organic hemp. CBD Ultra has created some truly stunning flavours by ditching the strong artificial tastes you normally get and using terpenes to create authentic cannabis strain blends. The result is mild, herbal flavours with subtle hints of citrus, fruit and candy; you can choose from OG Kush, Gelato, Watermelon OG, Pineapple Express, Lemon Haze and Blue Dream.

These potent 10% e-liquids are made with organically grown hemp from Colorado. Third-party lab tests are used to verify the cannabinoid content of every batch. They are also free from pesticides, solvents and GMOs.

You can choose from six natural flavours.

Strongest CBD Balm

Balms are applied directly to the source of irritation so aren’t in danger of being broken down by your digestive system. This means that they don’t need to be as concentrated to provide high strength effects. In topical balms, the CBD is often combined with oils and waxes to give an easily applied texture and to boost the scent and benefits.

This balm from Blessed CBD contains 750mg in 50ml. It’s a multi-purpose topical that can be applied anywhere to soothe irritated skin or to treat joint and muscle pain. In each jar, you get a full-spectrum of cannabinoids alongside several beneficial, natural substances including jojoba seed oil, shea butter and sweet almond oil.

A third-party lab thoroughly tests every batch of the balm. The cannabinoids are sourced from supercritical CO2 extracted hemp which is grown pesticide-free in Colorado, USA. Despite containing 750mg of CBD, there is no earthy hemp smell; the scent is mild and sweet and seems to get stronger as you apply it. It has a slightly waxy texture which goes after a while once you’ve smoothed it onto your skin.

The strongest CBD products will give you more options than many others. They are compact, versatile, value for money and are closer to the amounts used in studies. When you make your choice, remember not to buy anything that doesn’t come with an up-to-date certificate of analysis. Looking for customer reviews to hear the experiences of others will also help to ensure you get a good deal. Don’t forget to leave your reviews in the comments too.

Remember a large amount of CBD doesn’t always guarantee potency. Look out for products made with full-spectrum or whole-plant extracts. The taste may be unpleasant, but you will get a better quality product.
