The strongest CBD oil products in the UK

Once you’ve used CBD products for some time you will know precisely how much you should take each day. If you find you are having to take several drops or capsules, it may be time to look at high-strength products. These provide more cannabidiol (CBD) for your money and have a greater impact on your wellbeing.

Whilst extra-strong oils are better value in the long term, they do have a higher initial price. So, choosing the right product first time is key. We thought it would be useful to offer the benefit of our experience and provide you with a guide to the best and strongest oils, sprays, e-liquids and balms available in the UK.

What is considered high-strength CBD oil?

A high-strength CBD oil is any oil that has 25% or more concentration of cannabidiol relative to the amount of carrier oil. Oils with a concentration between 10% and 25% are medium strength and those below 10% are regarded low strength.

For example, 1000mg of CBD may seem like a large amount, but in a 10ml bottle the concentration is only 10% CBD. When you look for high-strength products you may find oils with a strength of 30% or 50%:

  • A 50% CBD oil in a 10ml bottle will contain 5000mg of CBD.
  • A 30% CBD oil in a 10ml bottle will contain 3000mg of CBD.

However, in other CBD products, different concentrations can be considered high strength because of the intensity of the effect they produce. For instance, e-liquids can be considered strong if they are 10% or higher and a balm can achieve a potent effect with 1%.

All these products are legally available in the UK if they meet the criteria set out by the MHRA and the UK government.

The benefits of strong CBD products

Strong CBD products are an excellent choice; they can save you money and provide a simple way to take large measures:

✅ Strong CBD saves you money – Although the most potent CBD products are often the most expensive, they can also be better value. By buying a large amount of cannabidiol in one go, you get more for your money. For example, one 10ml bottle of 5000mg CBD oil can cost less than five bottles of 1000mg oil.

✅ Stronger products are easier to take – With strong CBD, you only need to take a few drops or capsules to get a larger measure. For example, one drop of 40% (4000mg in 10ml) CBD oil delivers 20mg of CBD. To get the same amount from a 5% (500mg in 10ml) oil, you will need to take eight drops. This is a significant advantage because with fewer drops you’re more likely to deliver a precise measure. It’s also ideal if you’re don’t like the flavour of hemp, although the strong drop will have an intense flavour, it’s a little easier to swallow than a larger volume of oil.

The downsides of strong CBD

Although we highly recommend strong CBD products, they do come with some downsides:

High initial cost – Because of the high CBD content, strong products are significantly more expensive than those of lower concentrations. Even though they will likely save you money in the long run, you need to be prepared to pay a large amount up front.

No small measures – If you opt for an oil that delivers a large amount of CBD in one drop, such as 15mg to 25mg. This will always be the smallest measure you can take. If you decide you want to reduce your intake you won’t be able to go below that one drop serving.

2. Strongest CBD spray

Sprays are a simple way to take CBD. They deliver a jet of liquid directly under your tongue to be quickly absorbed into your bloodstream. They are often easier to apply than drops and prevent any wastage that might occur when opening and closing the bottle.

However, for a liquid to spray effectively, it mustn’t be too thick. This means that a lower strength concentration of 10% is considered to be strong for a spray because any stronger would block the pump.

Love CBD’s Entourage Spray contains 2000mg of CBD in 20ml. The full-spectrum extract is combined with an olive oil carrier, which adds a pleasant olive tang to the hemp flavour. One bottle can deliver 125 sprays, each with 16mg of CO2 extracted CBD. This will provide you with a supply of approximately 62 days if you take two sprays (32mg) each day.

Designed to provide the natural synergy of the entourage effect, Love CBD have produced this spray from a blend of carefully selected legal hemp strains. They are combined, following their own formula, to create a robust blend of cannabinoids and terpenes. Suitable for vegans, GMO-free, pesticide-free and made with entirely natural ingredients, this is an excellent product, of particular use if you’re on the go or in a hurry.

Love CBD are a Suffolk based company with a commitment to producing high-quality oils at affordable prices. Founded by Phil and Dan Culbertson, they have created a range of intricately formulated hemp blends that benefit from the enhanced potency of an entourage of cannabinoids and other plant substances. While their products don’t come with a formal organic certification, they prevent the use of pesticides, herbicides, artificial fertilisers or harmful chemicals on any of their farms.

Also in their range is the 7% Love CBD Entourage Spray with 1400mg of CBD in 20ml.

What reviews say: “The spray is very easy to use, I find it easier than a dropper.” – Anonymous, UK.

3. Strongest CBD vape oil

Vaping is another convenient and effective way of taking cannabidiol. Small portable pen-sized vaporisers are easy to carry with you and can be used discreetly. Inhaling vapour is one of the quickest ways to get CBD into your bloodstream and can deliver between 34-56% of each measure for use in your body.

Because a high percentage of CBD e-liquid reaches your bloodstream, concentrations of 10% are considered high strength. It is also easy to adjust the amount of CBD you can take by taking more puffs on the vape. As a result, 10% vape oils are ideal for those looking for strong CBD products. If you’re looking to boost the cannabinoid content of a low strength e-liquid, you can use this CBD Vape Additive from Love Hemp.

The all-natural CBD Ultra vape oil contains 1000mg of CBD in 10ml and is available in six terpene-rich flavours. They are based on popular cannabis strains and include OG Kush, Pineapple Express, Lemon Haze and Blue Dream. A 1ml vape tank can hold 100mg of CBD, giving you a 33-day supply if you use a daily amount of 0.3ml (30mg). Alternatively, if you prefer to spread it out over a more extended period, if you take 0.1mls (10mg) per day, a bottle can last for 100 days.

CBD Ultra has broken the standard mould for vape oils by ditching the PG/VG base and mixing a full-spectrum extract into coconut based MCT oil. The result is a high-quality e-liquid that produces an impressively potent, smooth vapour. The broad range of cannabinoids and terpenes, combined with the enhanced bioavailability of vaping, means that with just 1000mg of CBD this product genuinely deserves a place on this list.

CBD Ultra’s 10% e-liquids are made with organically grown hemp from Colorado, they are free from pesticides, solvents and GMOs. Third-party lab tests are conducted with each batch to verify the cannabinoid content and screen for contaminants.

What reviews say: “Good quality product, nice taste and at a fairly reasonable price. Would buy again.” – Lee F., UK.
