Discover the Strongest CBD Oil Products in the UK

Once you’ve used CBD oil for some time, you will know precisely how much you need to take each day. If you find you are having to take lots of drops, it may be time to look at high-strength CBD oil. A strong CBD oil provides more cannabidiol (CBD) for your money and can have a greater impact on your well-being.

Whilst strong CBD 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 CBD oils, sprays and e-liquids available in the UK.

Currently, the strongest and most effective CBD oil you can buy in the UK is CBD Ultra 50%, it is full-spectrum and contains 5000mg of CBD in a 10ml bottle along with a range of other minor cannabinoids. Each drop contains a whopping 25mg of CBD and is suspended in an MCT oil carrier.

1. What is considered high-strength CBD oil?

What is strong? over 25%

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 considered 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 between 25% and 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.

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.

The benefits of strong CBD oil

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

✅ 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 high-strength oil you will find they are nearly always cheaper per milligram of CBD in comparison to lower-strength products. For example, one 10ml bottle of 5000mg CBD oil will cost less than five bottles of 1000mg oil.

✅ Stronger products are easier to take – With strong CBD oils, you only need to take a few drops to get the right serving size. 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. It's also ideal if you don't like the flavour of hemp, although the strong drop will have an intense flavour, it's a little easier to hold under your tongue than a larger volume of oil.

The downsides of strong CBD oil

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. Yes, they will save you money in the long run, but you need to be prepared to pay a larger amount upfront.

No small measures – If you opt for an oil that delivers a large amount of CBD in one drop, such as 15mg (30% strength) to 25mg (50%). 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. So, if your requirements are less than this you could be spending more than you need to.

Strongest CBD spray - Love CBD Entourage

2000mg Love CBD

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 anything stronger would block the pump.

Love CBD’s Entourage Spray contains 2000mg of CBD in 20ml. The broad-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.

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.

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 that are highly effective. Suitable for vegans, GMO-free, pesticide-free and made with entirely natural ingredients, this is an excellent product, great if you’re on the go or in a hurry.

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

What our customers say: "I’ve been using Love CBD products for a while now and find that they are always of the best quality. It was the first brand I tried and still excellent and effective." - Heather W.

3. Strongest CBD vape oil - CBD Ultra 10%

CBD Ultra - 1000mg vape oilsVaping is another convenient and effective way of taking CBD. 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 bloodstream.

Because a high percentage of CBD e-liquid reaches your bloodstream using this method, 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.

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. 1ml of this e-liquid contains 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 their 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 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 our customers say: "Good quality product, nice taste and at a fairly reasonable price. Would buy again." - Lee F.

4. How to take a high-strength CBD oil

CBD affects each person differently, for some people a small amount of CBD provides the effects they seek, but others may need to gradually work towards taking larger servings.

Sublingual CBD oil application

Those who prefer to consume high-strength CBD often start with 30-60mg per day for a week. After that, they continue taking 45-90mg per day and increase or decrease the measure or frequency as required.

You should note that CBD is “biphasic”. A biphasic substance is one that can have two differing effects depending on the amount consumed. Alcohol is an excellent example of a biphasic substance. In small amounts it can make you happy and more outgoing but if you consume too much it can leave you feeling depressed and anxious.

So, if you find you are taking CBD in increasing amounts, but the effect is different to before, it could be because you are taking too much. Rather than then increasing the amount of CBD to get the same effect you may have more success by reducing it.

The most effective way to take oil or tinctures is to place them under your tongue to be absorbed sublingually. This allows them to be absorbed via the blood vessels and membrane under your tongue. After 1-2 minutes, wash the oil down with a glass of water. To boost absorption (bioavailability), follow with food that contains at least a little bit of fat such as oil or butter.

5. Precautions

CBD is generally well tolerated but, in some cases, can produce side effects. The most common potential side effects of taking CBD include a dry mouth, gastrointestinal problems and changes in appetite. When taken in large servings, the risk of more serious symptoms is greater; these can include low blood pressure, dizziness, headaches and liver toxicity.

CBD interacts with several commonly prescribed drugs producing unexpected results or negative effects. There are lots of medications that should not be taken with CBD, some of the main types include anti-coagulants, anti-convulsants, antibiotics, antidepressants, antifungals and beta-blockers.

To minimise side effects the Food Standards Agency (FSA) recommends a daily amount of no more than 70mg of CBD per day. They also advise that it should not be used if you’re taking medication, are pregnant or breastfeeding.

Why is high-strength CBD expensive?

Growing hemp plants

High-strength CBD products contain more cannabidiol and less additional ingredients such as carrier oils. The CBD is the most valuable ingredient because of costs incurred during the farming of the hemp and the manufacture of the final product. These are driven up by the value of the raw materials, procedures to ensure that it’s produced legally, and the sophisticated equipment required to extract it from the hemp.

This cost increase gets passed on to the customer resulting in a more expensive product because of the high concentration of CBD. However, in most cases, high-strength CBD gives you more of the active ingredient for your money, making it the most economical way to buy it.

Strong CBD oil is excellent value for money because of its high CBD content. With large amounts of CBD per container, you can choose to take them in a few potent measures or spread small amounts out over a more extended period.

Whatever the results you're looking for, there is likely a high-strength CBD oil that will suit your needs perfectly. Contact us if you'd like more information or advice on which product to choose.
