highest concentration cbd oil for pain

Best CBD Oils Reviewed: Top 3 Picks (2020)

There’s a lot of buzz around CBD (cannabidiol) these days. The cannabis-derived compound may ease anxiety, reduce pain and inflammation, improve sleep quality, and even has a few weight loss benefits.

It’s no surprise this natural plant oil has become so popular in recent years.

Unfortunately, not all CBD oils offer these benefits. There are hundreds of CBD brands in the United States alone — let alone throughout the world. Many of these companies are fly-by-night operations selling scam products, contaminated extracts, or “CBD-rich” oils containing virtually none of the active compounds.

Without proper regulation in the space, it’s easy to put together a makeshift CBD brand and sell low-quality products at a premium.

If you want your CBD to work, it’s essential to go with the very best CBD manufacturers. Here are three of the best CBD oil worth considering in 2020.

Best CBD Oils to Buy in 2020

Product Details:

Total CBD 250 mg – 2500 mg
Available Flavors Natural, Berry, Mint, Vanilla
Potency (mg/mL) 8.5 – 85 mg/mL
Extract Type Full-Spectrum

This brand makes a variety of premium CBD products produced locally in California from organic crops. The Royal CBD team takes pride in the quality of their work, and its reputation speaks for itself online with its massive cult following.

This brand has been mentioned on a variety of high-profile media outlets as the top-rated CBD oil on the American market — including LA Weekly, Observer, CFAH and more.

Royal CBD oils come in four different strengths — low (250 mg), medium (500 mg), high (1000 mg), and ultra-high (2500 mg).

The wide range of potency options for these 1 oz bottles of premium CBD allows you to choose a strength that works best. For example, if you’re a smaller individual (100 pounds or less), the low-potency 250 mg bottle of oil will probably work fine. However, if you’re a larger person (over 200 pounds), the 250 mg bottle probably won’t offer enough potency to give you the desired effects without having to use half the bottle.

Size isn’t the only factor here. CBD affects everyone differently. Some people need large doses of the oil, and others only need a few milligrams of CBD to get the desired effects. If you need a large dose, the high-potency bottles will last much longer and come with better value overall. If you only need a minimal dose, the lower potencies are better because it’s harder to take too much when the oil is more diluted.

All Royal CBD oils full-spectrum hemp extracts — which means they contain the entire range of cannabinoids and terpenes naturally produced in the hemp plant. The company uses state of the art CO2 extraction to produce these oils. Royal CBD tests each batch of product in-house and sends samples to a third-party lab for non-biased testing.

Overall, Royal CBD offers an incredible range of premium CBD oils at an excellent price point.

  • Premium full-spectrum oils
  • Organic, California hemp crops
  • Excellent value for cost per mg
  • Four flavor and potency options
  • In-house and third-party lab tested
  • Highly reviewed online
  • Only available online

Product Details:

Total CBD 300 mg – 1200 mg
Available Flavors Unflavored, Honey
Potency (mg/mL) 10 – 40 mg/mL
Extract Type Full-Spectrum

Gold Bee sells full-spectrum CBD oil in three potencies — low (300 mg), medium (600 mg), and high (1200 mg).

All three oils are top-notch in terms of both potency and price. Gold Bee is an artesian CBD oil manufacturer that charges industry-standard pricing. The founder believes in providing the best CBD oils possible without gouging on the price. He recently developed an innovative new extraction method that preserves significantly more terpenes than standard extraction methods.

This company’s extraction method has resulted in a lot of awards for the company’s CBD oils from a handful of reputable cannabis-related news outlets — such as Daily CBD, Weed News, and We Be High — to name a few.

These oils have a particularly high terpene ratio for a vibrant flavor and a much more robust and versatile effect profile.

The terpenes in the hemp plant contribute significantly to a quality full-spectrum CBD oil. Some terpenes (such as myrcene) offer additional relaxing and anti-anxiety benefits. In contrast, other terpenes (such as limonene) provide uplifting effects above and beyond CBD.

All Gold Bee CBD oils are thoroughly tested by an independent lab to assess the potency and purity of these oils.

  • Terpene-rich full-spectrum extract
  • Three potencies available
  • Excellent price for premium quality
  • Available in natural or honey infused
  • Third-party lab tested
  • Limited stock — waiting lists are common
  • Only available online or through select California dispensaries

Product Details:

Total CBD 125 mg – 4000 mg
Available Flavors Natural, Acai Berry, Chocolate Mint, Orange Creamsicle, Peppermint, Watermelon
Potency (mg/mL) 4.2 – 133 mg/mL
Extract Type CBD Isolate

Hemp Bombs makes its CBD oil from an isolate — which is a type of extract involving the removal of all the phytochemicals in the hemp plant except CBD. There are no terpenes or other cannabinoids in this oil whatsoever.

While most experts agree full-spectrum oils are superior to CBD isolates in almost every way, there are some situations where an isolate is ideal.

For example, CBD isolates only contain one active ingredient (CBD), so they’re a little better for people on a complex supplement or medication regimens (under medical supervision). With only one active ingredient in the oil, there are fewer chances of a negative interaction between the oil and other medications.

Additionally, CBD isolates tend to be more consistent in their effects (albeit weaker overall). A dose of CBD isolate from one company will have the same impact as an isolate of the same dose from another.

The same can’t be said for full-spectrum, which can vary depending on the other cannabinoid ratios, terpenes, and various other hemp-derived compounds in the oil.

Hemp Bombs sells this oil in many different potencies, ranging from 125 mg per bottle to a whopping 4000 mg per bottle.

  • Guaranteed THC-free
  • Widely available in-stores throughout the US
  • Seven flavors and six strength options
  • Budget-friendly
  • Third-party lab tested
  • Lacks benefits from other hemp-derived compounds
  • Unknown hemp source
  • Requires higher doses

Cannabis Terpenes

Cannabis makes several hundred individual terpene molecules — each with their own set of benefits. Terpenes are abundant in the plant kingdom where they’re commonly associated with the medicinal value of different plants.

Hemp shares many of the same terpenes to other medicinal plants. A few examples include:

1. Pinene — found in pine trees, has anti-inflammatory and antibacterial effects

2. Humulene — found in hops, has potent sedative and anxiolytic effects

3. Lavandin — found in lavender, has soothing and relaxing benefits

4. Bisabolol — found in German chamomile, has mild to moderate sedative effects

5. Limonene — found in citrus fruits, has uplifting and mood-enhancing benefits

Most experts recommend going for a full-spectrum hemp extract to take advantage of these terpenes. Alternatively, you can order terpene concentrates to give your CBD oil an added boost. A good source for premium terpene concentrates in the United States is Finest Labs.

Supplements That Combine With CBD Oil

CBD oil is a great overall health supplement. You can make it even better by taking it with other targeted health supplements to support your symptom or condition.

Common health supplements to combine with CBD oil include:

1. Ashwagandha KSM-66 — for stress & anxiety

2. Glucosamine — for joint health & arthritis

3. Reishi — for immune health

4. Kava root — for anxiety & insomnia

5. Astragalus — for immune function & allergies

6. Boswellia — for inflammation & joint health

7. St. John’s Wort — for mood & depression

Final Thoughts: What’s the Best CBD Oil Brand?

There are hundreds of different CBD companies operating in the United States. Many of these brands are making excellent CBD oils — but there are also many companies selling products that aren’t worth a single penny. It’s not uncommon to find contaminants such as cadmium or lead in some of the CBD products on store shelves.

The European CBD market is very similar, with plenty of low-grade companies pushing CBD oils that aren’t worth the money.

The best CBD oil companies test their products before releasing them onto the market. These companies check the oil themselves, but they also send a sample of each batch to an independent company for testing.

Third-party testing provides the ultimate level of transparency. It’s good practice to always look for evidence of this from a brand before you spend your money.

For the best quality oils overall for your dollar, Royal CBD is the way to go. Gold Bee comes in at second place for its high terpene profile and unique honey flavor for a few dollars more.

Why CBD Oil Potency Matters And 5 Of The Strongest CBD Oils

From a consumer’s perspective, potency is one of the most important things to consider when purchasing a CBD oil. There are many factors that distinguish one CBD oil from the next, but strength is the kicker, determining everything from the cost of a product to its ultimate therapeutic effectiveness. Yet such an important element is often misunderstood.

The strength of a CBD oil definitely depends on how much cannabidiol it contains. But other elements play important roles in the potency equation, too. How do you measure the strength of a CBD oil? Does strength really matter as much as everyone seems to think it does? And what exactly is CBD oil in the first place? In this guide, we dive into all of those questions and more, closing with a list of the five strongest CBD oils on the market.

Learn all about what makes a CBD oil strong, what experts consider “high potency,” and get answers to common questions and concerns about buying CBD oils, so you can make the best product choice for your health and wellness needs.

What is CBD Oil?

Let’s start with the basics. What exactly is CBD oil? The simplest answer is that CBD oil is a liquid product that consists of the cannabinoid cannabidiol (CBD) infused in a fatty carrier oil. Carrier oils are typically medium-chain triglycerides (MCTs) such as coconut oil, that are easy to digest and linked to many health benefits. Carrier oils can also be extra virgin olive oil, grapeseed oil, or as is commonly found in hemp-derived products, cold-pressed hemp seed oil.

At minimum, CBD oil consists of these two essential ingredients: cannabidiol and a carrier oil. But most products contain much more. Depending on the source of the CBD and how it gets extracted, concentrated, and processed, CBD oils can contain other cannabinoids such as THC and plant compounds including terpenes, flavonoids and other phytonutrients. The carrier oil can also add other ingredients to the oil, especially if derived from hemp or cannabis. Finally, some manufacturers might add aromatic ingredients such as essential oils to their finished products.

As a result of all these variables, CBD oils can vary dramatically in color, consistency, and flavor, even before taking strength into account. And strength largely depends on how a CBD oil is formulated. At one end of the spectrum, there’s CBD isolate, the strongest and purest form of CBD available. Using solvents or supercritical gases, manufacturers extract cannabidiol from every part of the hemp plant, producing a crystalized form of CBD that’s typically above 99% pure. CBD isolate isn’t an oil, per se. Instead, manufacturers suspend it in a carrier oil until it reaches the desired concentration.

Cannabidiol (CBD) oil can be sourced from hemp or marijuana plants. The difference is hemp-derived CBD contains 0.3% or less THC, while marijuana-derived CBD contains more and can only be purchased and used where marijuana is legal. (Photo by Shutterstock)

At the other end of the spectrum, there’s broad-spectrum or full-spectrum CBD oil. Typically, though not necessarily, sourced from hemp plants, broad-spectrum CBD oils have been minimally processed and purified. As a result, they contain the widest range of minor cannabinoids, nutrients, vitamins, terpenes and more.

In the middle of isolate-based oils and full-spectrum oils, you’ll find CBD distillates. Less refined than isolates, distillates contain more of the source plants’ cannabinoids, terpenes, flavonoids and other compounds. But they’re more refined than broad-spectrum oils. Distillates are more common in states with legal cannabis markets, since they usually contain more THC than the 0.3% limit set by federal law with the signing of the 2018 Farm Bill.

The boundaries between isolates, distillates and full-spectrum CBD oils aren’t always so clear. For example, a strong CBD oil made with a 99.7% pure isolate may also contain a range of minor cannabinoids and terpenes because it uses a broad-spectrum hemp seed oil as a carrier.

How Is Strength Determined?

At first glance, measuring the strength of a CBD oil seems simple. Read the label to see how much CBD a product contains, and voila. But because CBD oils can be isolates, distillates, or broad-spectrum, determining strength can be a bit tricky. Moreover, some product labels can make it harder to know exactly how strong a product is, or how potent a dose it provides. So we’ll start there, with the product label of a CBD oil itself. Then, we’ll take a look at how testing labs measure the strength of a CBD oil, and how that connects with what’s on the label.

“When you’re talking about strength, you’re talking about potency,” explained Adie Rae, a science adviser to Weedmaps News and an academic researcher with a Ph.D. in neuroscience who has been studying cannabinoids since 2004. “And that means how much CBD per volume.”

As Rae explained, you could have two CBD oils, both in 30 milliliter bottles. But one contains 3,000 milligrams of CBD and the other contains 6,000 milligrams of CBD. In this example, the stronger oil is the one with 6,000 milligrams of CBD per 30 milliliter container. In fact, it’s twice as strong, so you’d have to take twice as much of the less potent oil to achieve the same dose. And if the stronger CBD oil is less than twice as much as the weaker version, you’re saving yourself money by going with the more potent bottle.

Makers of cannabidiol (CBD) oils have not settled on a standard measurement for concentration. Some labels will list purity, while others will list percentage by volume (Photo by Shutterstock)

Sometimes, however, packages will tell you what percentage of CBD contained in the oil. This is where things can get confusing. A label may say that the CBD in the product is 99% pure if it contains a CBD isolate, or 70% if it contains a distillate. This tells you the strength of the CBD in the oil, but it doesn’t tell you how potent the CBD oil is by volume. And that means you won’t be able to tell how strong a dose is, so it’s important to find where the package indicates how much CBD it contains in milligrams.

From a lab technician’s perspective, however, determining CBD oil strength looks a little different. According to Myron Ronay, CEO of BelCosta Labs, manufacturers test for strength at every stage of the supply chain. They test the industrial hemp plants for CBD potency, then the initial “crude” oil and again at each stage of distillation. CBD oil manufacturers do this to ensure quality, consistency and legal compliance. But it’s a test of the final product that determines what gets printed on the label.

Most of the time, labs like BelCosta use High Performance Liquid Chromatography (HPLC) to measure CBD oil strength. For the technically curious, the test produces a table of wavelengths that act as the chemical fingerprints of various cannabinoids. This allows lab technicians to identify which compounds a sample contains as well as their relative quantities.

When testing for CBD oil strength, BelCosta analyzes for 14 different major and minor cannabinoids, including CBD, tetrahydrocannabinol (THC), cannabinol (CBN), and cannabigerol (CBG). The results show the percentage of CBD and other compounds in the sample. Reliable CBD oil companies will provide these results on their websites or product packaging.

Does Strength Matter?

Undeniably, today’s CBD market places a premium on potency. But does strength matter? And if so, how much? The truth is, we still really don’t know. When it comes to CBD, nothing is standardized. A dose that works for one person might be totally ineffective for someone else. Our individual bodies and metabolism, the bioavailability of different consumption methods and myriad other factors make experiences with CBD highly subjective and variable. Still, CBD consumers aren’t completely in the dark. Strength does matter, and in a few very important ways.

First, strength matters from the standpoint of efficacy. The stronger a CBD oil, the higher its potency, the more effects it’s going to produce. So what counts as a strong CBD oil? In the view of Rae, the cutoff for a “high potency” CBD oil is 35 milligrams per serving. Anything below that, and consumers are likely to have immeasurable blood levels of CBD.

“For me, when I’m buying hemp oil, I go for 50 milligrams CBD per milliliter,” Rae said. That’s a fairly high concentration of CBD, and one you won’t find in most CBD oil products below the $100 mark.

But potency (mg/mL) is only part of the larger strength equals efficacy equation. Research is still ongoing, but most experts agree that CBD on its own is going to be less effective overall than a full-spectrum oil containing roughly the same amount of CBD.

“No matter how much CBD isolate you’re taking, it’s not going to be as therapeutically beneficial as a broad-spectrum product,” Rae said.

BelCosta Lab’s Myron Ronay echoes Rae’s preference for broad-spectrum CBD oil over isolates. He said CBD is most effective when it can take advantage of the entourage effect, which is its interaction with other cannabinoids and terpenes in the oil.

To bind with the cell receptors of the human endocannabinoid system (ECS) and therefore produce therapeutic effects, CBD might need the help of THC and minor cannabinoids such as CBG, CBN, tetrahydrocannabivarin (THCV) and others. “Ratio is more important than strength in absolute terms,” Ronay said. “A little bit of THC goes a long way,” Rae said.

And that’s usually the difference between a broad-spectrum and a full-spectrum” product: full-spectrum cannabis oil contains THC. (Look out, though, for the word “full-spectrum” on products sourced from hemp; these have less than .3% THC in raw form). But outside of licensed medical or recreational cannabis dispensaries, CBD products have to contain less than 0.3% THC to remain legal. This makes it difficult to find products containing therapeutic levels of THC in states without legalized cannabis.

For consumers without access to legal cannabis shops, broad-spectrum products (without the THC) are the next best thing, because they often combine high-strength isolate or distillate with broad-spectrum hemp oil. In short, you should ultimately choose a strong CBD oil that contains the most ingredients possible.

Swallowing cannabidiol (CBD) oil reduces most of its effectiveness. The bioavailability, or the ability of CBD to reach the bloodstream and produce its therapeutic effects, is around 5%. (Photo by Shutterstock)

Rae has some more crucial advice for CBD oil consumers looking for strength. Don’t swallow it! Studies have shown that the oral bioavailability of CBD is shockingly low, at just around 5%. In other words, only a fraction of the CBD oil you swallow is making it into your bloodstream where it can produce therapeutic results. But as Rae explained, there are a couple ways to hack CBD’s low bioavailability.

First, keep the oil under your tongue for as long as possible; try to make it to 4 or 5 minutes. “This method treats the oil more like a topical than an edible, and keeps the CBD safe from the digestive enzymes that break it down,” Rae said.

Second, if you do have to swallow the oil, take it at the same time as some black pepper. Piperine is a molecule in black pepper that shuts down the drug-metabolizing enzymes in your liver, giving CBD a better chance of getting absorbed.

Finally, no discussion of the importance of CBD oil strength would be complete without tackling the issue of product safety. It’s important to keep in mind that outside of licensed dispensaries, CBD products are still unregulated. There’s no real rules yet for acceptable levels of pesticides, chemical fertilizers, heavy metals and other contaminants. Screening for them isn’t required, and there are no restrictions on selling products that contain them. The only thing that matters is staying below the 0.3% THC threshold.

High-potency CBD oils in particular amplify concerns about contamination. As Ronay explained, concentrating for potency involves concentrating everything else in and on the hemp plant, too. “How do you know what’s in it or what’s safe? People are looking for a cure and for health and facing the unknown,” Ronay said.

But you don’t have to face the unknown. Here are five of the strongest CBD oils on the market, selected based on their potency, efficacy and how transparent the company is with what’s inside the bottle. Keep in mind, strength is all relative. What matters is potency: how much CBD a single dose provides, whether it’s a drop or a full milliliter dropper.

The oils below are all CBD-heavy, at concentrations way above the average product, with prices to match. We favored broad-spectrum oils due to their added therapeutic benefits. And remember, if you want to make your CBD oil stronger, all you need to do is take more of it!

5 of the Strongest CBD Oils on the Market MyNaturalCBD — 5,000 milligrams Full-Spectrum Hemp Oil Tincture (30 milliliters)

Some oils you take by the dropper. This one, you take by the drop. At 5,000 milligrams of CBD, you’d be hard pressed to find a stronger CBD oil at the 30 milliliter level. Lab results indicate an even higher 5,280 milligrams of CBD, along with trace (and legal) percentages of THC, cannabidiolic acid (CBDA) and CBG. And to make way for all that cannabidiol, MyNaturalCBD uses a simple formula. This product fuses high-potency CBD with a blend of full-spectrum hemp oil and MCT oil from coconuts.

A high-potency CBD oil like this allows you to fine-tune your dosage. Each drop contains a little more than 8 milligrams of CBD. With four or five drops, and you’ve reached that 35-milligram-per-dose benchmark. A 0.5 milliliter dose would deliver 84 milligrams of CBD.

Cannabidiol Life — 6,000 milligrams Whole Plant Hemp Extract CBD Oil (120 milliliters)

Cannabidiol Life’s most potent offering is a perfect example of why it’s important to measure a CBD oil’s strength by volume. At 3,000 milligrams CBD, this whole plant hemp extract oil contains more cannabidiol than most products on the market. But its potency isn’t as extreme as it may appear. This is a 60 milliliter bottle, putting CBD potency at a humbler 50 mg/mL — therapeutically beneficial, but not chart-topping. Still, because Cannabidiol Life contains so much CBD, you can easily obtain 75–100 mg/mL doses, or higher, if required.

Enjoyable CBD — 3,000 milligram Full-Spectrum CBD Tincture (30 milliliters)

Enjoyable CBD’s full-spectrum CBD tincture clocks in at 100 mg/mL. And while that may not be the strongest CBD oil on the market by the numbers, it’s one of the strongest in terms of how much CBD gets into your bloodstream. That’s because this CBD is all about bioavailability. Enjoyable CBD uses full-spectrum Imperial CBD Oil, a formula which uses molecular encapsulated CBD to help improve how well your body absorbs the cannabidiol.

The unique extraction and distillation process produces a completely THC-free oil, however, so this is a case where strength may require a trade-off with the benefits of the entourage effect.

Green Roads — 3,500 milligrams Pharmacist Formulated CBD Oil (60 milliliters)

Green Roads is a prominent name in CBD products, and its 3,500 milligram CBD oil is its flagship product. Each milliliter of this formula delivers 66.36 milligrams of hemp-derived CBD, according to the most recent lab sheets — stronger than advertised. Green Roads’ formulates this broad-spectrum CBD oil with a proprietary blend of terpenes, sourced from hemp seed oil.

Consumers can take confidence in the clear and regularly updated lab sheets provided about this and all Green Roads products. And Green Roads isn’t just testing for CBD. It also screens for pesticides, solvents, heavy metals, microbials and other contaminants and only sells products from batches that pass all tests.

Hempassion — 4,000 milligrams Nature’s Nectar CBD Oil (10 milliliters)

This is a 10 milliliter bottle of CBD oil that contains 7.26 grams of cannabidiol in a 55 percent CBD distillate. Germinated hemp seed oil, this product’s carrier oil, adds even more CBD in addition to minor cannabinoids, terpenes and other hemp phytonutrients. Hempassion says germinated hemp seed oil is one of the most nutritionally balanced supplements currently known.

According to Hempassion, each milliliter of Nature’s Nectar CBD oil contains 20 drops, and each drop contains about 20 milligrams of cannabidiol. Two or three drops under the tongue is all you need for a therapeutically significant dose of this ultra-high potency CBD oil. This is a product that highlights the cost savings of purchasing more concentrated CBD oils.

The Strongest and Most Effective CBD Oil in the UK

By now, we know that the CBD market is a multi-billion dollar one in North America, but what about the UK? Or the rest of the world, for that matter? As it happens, dozens of countries embrace cannabidiol, none more than the United Kingdom.

A market report entitled: “Green Shoots – Sowing The Seeds Of The New UK Cannabis Industry” revealed that the UK CBD market was worth £690m in 2021. Meanwhile, research commissioned by the Centre for Medicinal Cannabis revealed that 6 million people in the UK had consumed at least one CBD product in the last 12 months, a percentage that seems certain to increase in the years to come.

Yet, despite the size of the market, UK CBD customers are still learning the ins and outs of which products work best and why. This guide looks at five of the strongest CBD oils in the UK for those looking to maximize potency and hoping to benefit from pain relief, stress, anxiety relief, and more.


  • High-milligram CBD options can potentially provide very strong effects
  • Potent options often last longer than standard (mid-range) CBD oils
  • A single high-milligram dose can be effective for an entire day (rather than having to take several doses throughout the day)
  • Many individuals find high-milligram CBD oils effective when other CBD products are not
  • Price (the strongest UK CBD oils are, obviously, also the most expensive)
  • High-milligram CBD oils in the UK can be tough to find in retail stores


Our near-unanimous pick for the high-quality, strongest CBD oil in the UK is Provacan. This company has been around for quite some time, and its reputation for quality, effectiveness, and overall value continues to grow. Hit the button below to access the site and start shopping.

What Is Considered Strong CBD Oil?

There is no universally accepted definition of strong CBD oil. Not that long ago, a 1,000mg container of CBD oil offering 33mg of the cannabinoid per ml was considered top of the class in strength terms. These days, such a CBD concentration is classified as ‘par for the course.’

Realistically, a strong CBD oil will contain at least 50mg per ml, although 100mg is becoming more common. Indeed, we highlight a brand in this article that includes 200mg of CBD per ml!

However, it is important to focus on more than the amount of CBD per ml. Make sure the brand can provide third-party reports with each product. Otherwise, you are only taking its word for it concerning the strength of its CBD. Also, please stick with companies that source their hemp from licensed EU and American hemp farms.

The Strongest CBD Oils in the UK

UK residents certainly have no shortage of options. This is why, for some of the different sections below, we tested and included a couple of different brands that we feel stand out. Here are our team’s picks for the highest milligram, most potent, strongest CBD oils in the UK without further ado.


For this section, our team narrowed it down to three separate brands. However, after we reviewed each product, the winner became clear.

Love Hemp

This brand claims it is the #1 supplier of CBD and hemp products in the UK. It is a London-based company founded in 2015 that has earned praise for its innovative CBD water. However, Love Hemp’s CBD oil stands out regarding milligram strength and potency. We tested a 100ml bottle of broad-spectrum liquid that contained an extraordinary 10,000 mg of CBD with no THC and were very pleased with the results.

It’s also worth pointing out that Love Hemp’s CBD is extracted using solventless technology. The hemp it uses is grown without hormones, chemical fertilizers, or genetically modified products. Love Hemp uses just three ingredients in this product: CBD hemp extract, organic coconut MCT oil, and natural flavourings. It is also suitable for vegetarians and vegans.

Hemp Botanics

When we reviewed this oil, the terpene content stood out initially. Terpenes give cannabis its unique flavour and aroma profile, so this product tastes delicious. Unlike other UK sellers, however, Hemp Botanics’ products contain American-hemp-derived cannabinoids, which genetically are considered some of the best in the world.

The 4,000mg CBD oil sold by Hemp Botanics contains an impressive 66mg of broad-spectrum CBD per ml, according to the packaging. A recent lab report revealed 70mg of CBD per ml and 2.77mg of CBG. Ingredient-wise, there is nothing in this oil barring CO2 extracted broad-spectrum hemp oil and organic fractionated coconut oil.


This is the best CBD oil we have tried. While other brands on the list may have higher-potency products, Provacan has the edge in terms of pure results.

The brand is part of the CiiTECH family, which happens to have its own extraction facility and research laboratory. Third-party labs still test Provacan products, but it performs a detailed level of analysis in-house that few competitors can compete with. All Provacan CBD oils come from certified organic EU hemp and are made with a full-spectrum formula to ensure consumers benefit from the entourage effect.

Additionally, several Provacan CBD oils are kosher-certified and contain CBD, CBDv, CBG, CBDa, and naturally occurring omega acids, flavonoids, and terpenes. The products are developed with expert researcher teams in Israel, allowing for a true one-of-a-kind CBD formula.

Provacan has also released CBD Oil Spray Gold in 300mg, 600mg, and 1,200mg concentrations. The strongest version offers 20mg of CBD per spray, meaning that many users only require a single spray each day. The MCT carrier oil is a mixture of coconut and rapeseed oil, and the product includes terpenes.

As we expected from such a highly-regarded brand, Provacan uses supercritical CO2 extraction to “pull” the CBD, terpenes, and other cannabinoids from the organic hemp plants. While this may not be the strongest CBD oil in the UK in terms of cannabidiol per ml, we feel it is the best quality – and at the end of the day, that’s what matters.
