What makes a "strong" CBD oil is how much cannabidiol (CBD) is delivered per milliliter (or per dropper). We're proud to offer one of the strongest CBD oils on the market — with one of the most competitive price points: 12,000 mg CBD per 2 fluid ounces (60 mL), or 200 mg per 1 mL dose, for $185. That's $2.85 per dose.
And we ship to the UK. Our THC-free option is a broad spectrum extract that contains complementary cannabinoids that help bolster the effects of CBD, but without THC, so it complies with many European countries' laws that restrict THC to only 0.2% in hemp products.
With high-strength CBD oil, you can reach higher doses with less product, making it more cost-efficient and convenient for those seeking greater support from their CBD products.
5 Strongest CBD Oils In the UK
If you're shopping at your local high street or specialty CBD stores in person, you may be limited on high-potency CBD oil options, which is why many people purchase it online. From my personal experience shopping in London, I saw very few options that went above 4000 mg per 1 oz bottle, which won't give you a powerful dose compared to those on this list. Here are some of the most potent CBD oils you can find in the UK.
Love Hemp 10,000 mg
Love Hemp is a popular CBD brand stocked in many physical retail shops across the UK, like Holland & Barrett, Tesco, and Boots, which is why it's so recognizable for locals. Even though you can find this brand in person, you may have trouble finding its high-concentration CBD oil. Check online if you can't find it at your local store.
Love Hemp has a 10,000 mg, broad spectrum CBD oil that delivers 100 mg per 1 mL serving. £149.99.
Orange County CBD 12,000 mg
Orange County CBD is a UK-based CBD company with roots in California (hence its name) with a fairly extensive range of full spectrum hemp formulations on its online shop.
Notably, 12,000 mg of full-spectrum CBD oil (100 ml bottle) delivers 120 mg per mL, making it a highly concentrated solution. It comes at a slightly higher price point at £162.99.
Supreme CBD 24,000 mg
Supreme CBD is a London-based hemp brand that sells full-spectrum and broad-spectrum CBD oils, and it's relatively new (5 years old) compared to the other veterans we mention on this list.
The 24,000 mg full-spectrum CBD oil (100 mL bottle) is one of the strongest oils we've come across, administering 240 mg of CBD per mL. Right now, you can get this bottle for £229.99, discounted from the regular £399.99 price.
Honey Haven 5000 mg (50%)
Honey Haven uses Swiss-crafted CBD oil in its products. Rather than high-volume CBD oils, this brand focuses on potency in a small, 10 ml package and claims to have"the strongest CBD oil on the market."
The 5000 mg (50%) oil equates to 500 mg per 1 mL for £135.00 — but you wouldn't usually take 1 mL of this product at a time.
Because there's only 10 mL total in the small dropper bottle, this product is meant to be taken on a "drop-by-drop" basis. 1 drop has 27 mg of CBD, which is highly concentrated. This is useful for advanced users who want that high strength without taking large volumes of carrier oil.
Neurogan 12,000 mg
We're a San Diego-based CBD company with Danish roots, in the game since 2016. We're known for offering some of the strongest full-spectrum and broad-spectrum CBD oils on the market, with highly competitive prices and worldwide shipping (where CBD products are legal).
Because American standards for full-spectrum CBD oil allow up to 0.3% THC, we recommend purchasing our broad-spectrum 12,000 mg CBD oil (60 mL), which still contains many complementary terpenes and cannabinoids but is THC-free, making it legal to ship to the UK. Compared to the other brands on this list, at only $185 USD, it's still one of the more affordable options.

What Makes a High-Strength CBD Oil?
A high-potency CBD oil is defined by how much cannabidiol it delivers per milliliter — typically over 100 mg/mL — with clean extraction, verified lab tests, and a rich cannabinoid profile that enhances absorption and effects.
We're proud to say that our 12,000 mg broad spectrum CBD oil exemplifies this standard and stands on par with the many great options available in the UK.
Made in San Diego with Danish roots, our product contains 200 mg of CBD per mL and zero THC, making it legal to ship to the UK while still providing the entourage benefits of additional cannabinoids and terpenes. With transparent third-party testing, premium US-grown hemp, and a highly competitive price point compared to similar UK oils, Neurogan stands out as one of the best high-strength options for experienced users worldwide.
