We have worked with CBD since 2016, tried a great many oils ourselves and helped thousands of customers understand the differences between them. We now care less about the largest percentage on the label and more about the things that affect a real purchase: lab evidence, taste, value, suitability and honest personal guidance.

Our original selection checklist, shown here, still gets the basics right: clear cannabinoid content, careful extraction, accessible lab testing, responsibly grown hemp, a cannabinoid-rich formula and first-hand product experience. We now add four practical questions:
This guide ranks the things we can properly assess. It does not rank oils by claims about pain, anxiety, sleep or any other condition. Customer reviews are useful for understanding taste, packaging, service and repeated purchase, but an individual review cannot prove a medical effect.
BioBloom 8% is our best CBD oil in the UK overall. It combines certified-organic hemp, a naturally broad CBD and CBDa profile, unusually detailed supporting documents, a practical amount per drop and strong customer feedback. Our own Signature Collection 15% is second, followed by Biopurus 5%.
| Rank and oil | Best for | Labelled cannabinoids | Approx. amount per unit | Evidence | Price and value | Verified reviews |
|---|---|---|---|---|---|---|
| 1. BioBloom 8% | Best overall; an organic whole-plant starting choice | 800mg in 10ml or 2400mg in 30ml, stated as CBD and CBDa combined | About 4mg CBD and CBDa combined per drop | Cannabinoid certificate, microbiology specification and organic certificate | £36.90 / 10ml or £86.90 / 30ml; about 4.6p or 3.6p per labelled cannabinoid mg | 4.9/5 from 38 reviews |
| 2. Signature Collection 15% | Best equal-parts CBD, CBG and CBC formula; exclusive to for the Ageless | 500mg CBD + 500mg CBG + 500mg CBC in 10ml; 1500mg in total | 2.5mg CBD + 2.5mg CBG + 2.5mg CBC per drop | HPLC certificate; formulated and made in the UK by GreenLeaf Processing | £64.90 / 10ml; about 4.3p per total cannabinoid mg or 13.0p per CBD mg | 4.5/5 from 4 reviews |
| 3. Biopurus 5% | Best lower-cost certified-organic option; easy 2.5mg adjustments | 500mg CBD in 10ml | About 2.5mg CBD per drop | Cannabinoid certificate and organic certificate | £28.90 / 10ml; about 5.8p per CBD mg | 4.8/5 from 64 reviews |
| 4. CannabiGold Select | Best pump bottle; simple measuring and travel | 1000mg CBD in 12ml | 10mg CBD per complete pump | Cannabinoid certificate; full-spectrum, without organic certification | £49.99 / 12ml; about 5.0p per CBD mg | 5.0/5 from 36 reviews |
| 5. Love CBD Entourage 2000mg | Best spray format; experienced users who value portability | 2000mg CBD in 20ml | 16mg CBD per spray | Cannabinoid certificate and terpene profile; without organic certification | £99.99 / 20ml; about 5.0p per CBD mg | 5.0/5 from 6 reviews |
Prices and review figures checked 25 August 2026. Ratings and prices can change. Values are rounded and use the labelled cannabinoid content. Combined CBD, CBDa, CBG and CBC totals are not directly equivalent to CBD alone.

Our rankings combine evidence on the product with first-hand experience of using it. We also look at the pattern across customer reviews. These are the same practical priorities customers raise with us every day: whether they can trust the product and retailer, whether it represents fair value and whether the strength makes sense for them.
| What we assess | Why it matters | What we look for |
|---|---|---|
| Lab testing | The front label cannot confirm what is in the bottle. | An accessible cannabinoid certificate, an identifiable laboratory, useful batch information and contaminant or microbiology evidence where available. |
| Taste and usability | A technically impressive oil is little use if the flavour or bottle makes it unpleasant to take. | Taste, texture, carrier oil, dropper accuracy, pump or spray operation, leakage and ease of travel. |
| Value | A small bottle or impressive percentage can disguise poor value. | Price per relevant cannabinoid alongside certification, testing, formulation and whether the amount per serving is practical. |
| Suitability | The strongest oil is often the hardest to measure appropriately. | A clear amount per drop or spray, room for small adjustments, current FSA advice, medicines and individual circumstances. |
| Personal guidance | The choice can still be confusing after comparing the labels. | Clear answers, realistic expectations and a willingness to suggest a lower strength, another format or professional advice when appropriate. |
In an official analysis of 100 CBD products, the FSA found that 49 matched the CBD amount stated on the label, eight contained more and 43 contained less. This is why “lab tested” is not enough for us. Customers should be able to open the actual certificate.
A certificate can help confirm the measured cannabinoid profile of the tested sample. It cannot prove that the product will produce a particular result for you. Read our guide to CBD lab reports. The supporting FSA analysis is also available from the Food Standards Agency.
A perfect score from six people does not carry the same weight as a 4.8 score from 64. The comparison table therefore shows both. We use the Stamped reviews attached to the relevant products and focus on recurring comments about taste, texture, packaging, value and service. We do not treat a reviewer's health result as medical evidence.
BioBloom takes first place because it offers the strongest all-round balance, rather than the largest percentage. The Austrian family behind it has three generations of organic-farming experience in Burgenland and controls the process from hemp cultivation to the finished oil. The whole-plant extract uses CO2 extraction and carries recognised organic certification.
The 8% oil contains CBD and CBDa, with smaller amounts of other hemp compounds. BioBloom publishes more supporting information than most brands: a cannabinoid certificate, terpene profile, microbiology specification and organic certificate. We have been an authorised UK BioBloom retailer since 2018 and know the oil well.
Organic status is useful because hemp readily reflects the conditions in which it is grown. BioBloom has received three separate forms of certification or quality recognition: Austrian and Hungarian BIO certification, certification from the UK’s Biodynamic Association, and the ARGE Canna AC Drop quality seal.
These are not three versions of the same organic badge. They assess different aspects of cultivation, environmental care, and hemp-extract quality, giving us a broader basis for judging the standards behind the bottle.
Certification cannot show the exact CBD-to-CBDa balance in an individual batch. This is why we also value BioBloom’s cannabinoid certificate, terpene profile, microbiology specification, and current organic product certificate. Together, these documents provide evidence of both hemp cultivation and the finished oil.
BioBloom centres on certified-organic, whole-plant oils, with hemp flower teas, tea bags, gummies and balms completing the collection. The family controls the oil from seed to bottle and uses the same organic hemp flowers for its teas. This gives the range an unusually consistent whole-plant character.
Taste: the oils are dark, herbal and distinctly hemp-like. Customers describe the extract as raw and more viscous than filtered oils, which matches our experience. This is a strength for somebody who wants a product close to the plant, but less suitable for anyone seeking a neutral flavour.
Value and suitability: the 10ml 8% bottle is the sensible way to try BioBloom. The 30ml size has the lowest approximate cost per labelled cannabinoid mg in this comparison once you know you like it. The pipette allows small adjustments, although the thick oil and bottle are less convenient for travel.
The 10ml bottle is the sensible trial size. The 30ml bottle reduces the approximate cost from 4.6p to 3.6p per labelled cannabinoid mg. Each drop contains about 4mg CBD and CBDa combined, although the natural split varies by batch.
★★★★★
For someone trying to capture the whole plant, this is by far the best product I have tried. It has a raw feel to it and is much more viscous than the others.
BioBloom 8% currently averages 4.9/5 from 38 Stamped reviews. Read the product reviews.
Read our interview with BioBloom founder Christoph Werdenich.
The Signature Collection is a permanent part of this guide because we commissioned it directly from GreenLeaf Processing in response to customer requests. GreenLeaf is the UK operation behind CBD Brothers and The Original Alternative. The collaboration gives us a direct relationship with the maker and a formula created for the people who shop with us.
The 15% oil contains 500mg CBD, 500mg CBG and 500mg CBC in 10ml of C8 MCT oil. One drop provides approximately 2.5mg of each cannabinoid. The combined amount is 7.5mg, but only 2.5mg of that is CBD. This is a useful example of why the headline percentage needs explaining.
The hemp is grown in the Netherlands following organic production standards, but the finished oil does not carry independent organic certification. We therefore do not describe it as certified organic. The published HPLC certificate and exact cannabinoid breakdown are the stronger reasons to consider it.
The collection currently centres on two distinct oils made for us by GreenLeaf Processing. Signature 15% balances CBD, CBG and CBC equally. Signature 50% puts most of its concentration into CBD while retaining 500mg each of CBG and CBC. Both use a full-spectrum hemp extract in C8 MCT oil.
Taste: the MCT C8 carrier is mild and slightly buttery, so both oils taste gentler than dark hemp-seed formulas. Signature 50% also has a peppermint option for people who find the natural hemp note difficult.
Value and suitability: Signature 15% offers the better balance for most people considering this collection because each drop contains only 2.5mg CBD alongside equal CBG and CBC. Its value lies in those harder-to-find cannabinoids, rather than cheap CBD alone. Signature 50% is more economical per CBD mg but one drop contains 20mg CBD, making it a specialist choice for experienced users rather than a starting oil.
The 15% formula is our normal starting point within the collection. It gives meaningful amounts of CBG and CBC while keeping the CBD contribution to 2.5mg per drop. The mild MCT carrier is easier for many people than a dark hemp-seed oil.
★★★★★
Brilliant product. Strongly recommend.
This review is for Signature 50%, the longer-established oil. It averages 5.0/5 from 46 Stamped reviews. Read the Signature 50% reviews.
The 50% oil contains 4000mg CBD + 500mg CBG + 500mg CBC. Its 5000mg headline is the combined total, not 5000mg CBD. It comes in Natural and Peppermint, with a separate certificate for Natural and Peppermint.
One drop provides about 20mg CBD plus 2.5mg CBG and 2.5mg CBC. The CBD alone is twice the FSA's current precautionary daily amount for a healthy adult. This remains an important specialist product and has excellent customer feedback, but it is not the normal place to begin.
Use our guides to CBG and CBC to understand the formula.
Biopurus is the least expensive 10ml bottle in the top five and one of the easiest to adjust. Each drop contains approximately 2.5mg CBD, allowing smaller steps than a 10mg pump or 16mg spray. The hemp is certified organic, the extract is full-spectrum and both cannabinoid and organic certificates are easy to reach.
This is a dark, thick oil with a strong earthy taste. Some customers actively prefer that whole-plant character. Others use a milder formula more consistently. GreenLeaf Processing now manufactures the oils, while the Biopurus hemp teas continue to be produced in the Czech Republic.
Biopurus combines certified-organic whole-plant oils from 5% through to 30% with one of the broadest organic hemp-tea selections we stock. GreenLeaf Processing makes the oils in the UK, while Biopurus continues to produce the teas in the Czech Republic using Central European organic hemp.
Taste: these are full-bodied, earthy oils that retain chlorophyll, lipids and other plant material. Their strong flavour divides opinion, but the review pattern shows that many regular customers actively prefer that authentic whole-plant character.
Value and suitability: Biopurus 5% has the lowest initial price among the five main recommendations and gives small 2.5mg CBD drops. The three-bottle bundle includes 1.6% hemp tea, making it the simplest ready-made oil-and-tea combination in this guide. It suits somebody prioritising organic certification and measured adjustments more than somebody wanting a mild travel oil.
The 500mg 10ml bottle costs £28.90 and gives approximately 200 drops. Four drops contain about 10mg CBD, so it is easy to understand and adjust within current guidance.
★★★★★
The customer service I received was great. The oil itself, I really like it. Tastes great.
Biopurus 5% currently averages 4.8/5 from 64 Stamped reviews, the largest product-review sample among the five main oils. Read the product reviews.
CannabiGold solves an ordinary but important problem: counting tiny drops. Its side pump delivers approximately 10mg CBD in one complete press. It is clean, consistent and easier to use away from home than an exposed glass pipette.
The oil is more filtered than BioBloom or Biopurus and tastes milder and slightly nutty. It remains full-spectrum and has a publicly available cannabinoid certificate. The hemp comes from European farms, although the finished product is not certified organic.
HemPoland began making CannabiGold in 2014, when it became the first Polish company to receive a state licence to grow hemp and manufacture CBD products. It manages the process from cultivation to extraction and uses its own Supercritical Fluid Extraction method. This retains a broad range of hemp compounds while avoiding the conventional solvent residues associated with some extraction methods. Batches are checked for cannabinoid content and contaminants including heavy metals, pesticides and moulds.
The CannabiGold range uses a side-pump system across several strengths and also includes pre-measured capsules. HemPoland controls the process from European hemp cultivation through extraction, then checks cannabinoid levels and contaminants in the finished oils.
Taste: CannabiGold is filtered to a clear golden colour and has a mild, slightly nutty flavour without the visible plant particles found in darker whole-plant oils. This makes it one of the easiest options for people who struggle with strong hemp flavours.
Value and suitability: Select contains 100 complete pumps, each delivering 10mg CBD, at about 5p per CBD mg. The sealed pump is tidier for everyday use and travel than a conventional pipette. It suits somebody who wants a repeatable complete serving, although it does not allow adjustments below 10mg.
The 12ml bottle contains 100 pumps and is deliberately not filled to the neck so that it can be shaken properly. Each complete pump gives 10mg CBD, making this the clearest direct match to the current FSA precautionary figure for a healthy adult.
★★★★★
There is never any unpleasant aftertaste from this high-quality product.
CannabiGold Select currently averages 5.0/5 from 36 Stamped reviews. Feedback often supports the practical strengths we notice ourselves: mild taste, tidy packaging and consistent measuring. Read the product reviews.
Love CBD is a Suffolk family business established in 2014. Its Entourage oil combines extracts from several hemp varieties in an olive-oil carrier. The leak-resistant spray remains one of the most practical formats for carrying in a handbag or pocket or taking on a journey.
The extract uses hemp grown in the Netherlands, Lithuania, Slovenia and Croatia. Love CBD says its supplying farms avoid pesticides, herbicides and artificial fertilisers. The finished oils undergo third-party cannabinoid and contaminant checks.
Love CBD also publishes a cannabinoid certificate and separate terpene profile. These are particularly useful for a multi-strain extract because they show what was measured in the finished product rather than relying only on general claims about the plants used.
Love CBD concentrates on full-spectrum sprays, capsules and topical balms. The family business combines extracts from several European hemp varieties and publishes both cannabinoid and terpene evidence for its Entourage oil.
Taste: the olive-oil carrier gives the spray a softer texture, although the multi-strain extract still has a recognisable herbal flavour. The spray spreads the oil more widely than a pipette, which is worth considering if taste is your main concern.
Value and suitability: the 2000mg bottle costs about 5p per CBD mg and the sealed format is easy to carry without counting drops. Its main limitation is measurement: one spray contains about 16mg CBD. This makes it more suitable for an experienced user who values portability than for somebody trying CBD for the first time under current FSA advice.
The 20ml bottle is well made and convenient, but each spray provides about 16mg CBD. That is above the FSA's current precautionary daily amount for a healthy adult, so this strength sits behind the lower-unit options for a beginner.
★★★★★
I would not have felt comfortable without having had his guidance.
The review refers to a conversation about selecting an appropriate Love CBD strength. Love CBD Entourage 2000mg currently averages 5.0/5 from six Stamped reviews. Read the product reviews.
Read our interview with Love CBD co-founder Phil Culbertson.
Full-spectrum CBD contains CBD with other naturally occurring cannabinoids and plant compounds. Depending on the product and batch, these can include CBDa, CBG, CBC, terpenes and controlled cannabinoids within applicable legal limits.
Broad-spectrum CBD retains several cannabinoids while being processed to remove THC as far as the method allows. CBD isolate is highly purified CBD with most other hemp compounds removed.
We often prefer a well-made full-spectrum oil when somebody wants a broader hemp profile. This describes composition; it does not prove that the oil will work better. The proposed entourage effect remains a theory with mixed and incomplete clinical evidence. Read our updated full-spectrum, broad-spectrum and isolate guide and our separate explanation of the entourage effect.
Whole-plant oils such as BioBloom and Biopurus are dark, herbal and earthy. CannabiGold is more filtered and milder. Signature uses C8 MCT oil and is less hemp-like. Love CBD combines hemp extract with olive oil.
A pipette allows small adjustments but can become oily around the neck. CannabiGold's pump is precise and tidy. Love CBD's spray travels well, although the amount in one spray makes the current 2000mg version a poor first choice for many beginners. Read what different CBD oils taste like.
Price per mg prevents packaging and percentage from disguising poor value, but it must be interpreted properly. BioBloom's 30ml bottle has the lowest approximate cost per labelled mg among the five main oils. Signature 15% also appears competitive when all three cannabinoids are counted, but it costs more if CBD alone is the measure that matters to you.
A very concentrated oil can look inexpensive per mg while still being unsuitable. Signature 50% costs about 4.6p per CBD mg, yet one drop contains 20mg CBD. The useful calculation is cost per relevant cannabinoid, evidence, formula and whether you can measure an appropriate amount. Our CBD oil price guide goes into more detail.
CBD strength may appear in milligrams or as a percentage. Milligrams show the amount in the container. A percentage shows concentration and only becomes meaningful when you also know the bottle volume.
The first table converts common CBD percentages into milligrams. It applies when the stated percentage refers to CBD alone. Signature 15% and Signature 50% use combined-cannabinoid percentages, so use their individual CBD, CBG and CBC figures instead.
| Bottle size | 4% | 5% | 10% | 20% | 30% | 40% | 50% |
|---|---|---|---|---|---|---|---|
| 10ml | 400mg | 500mg | 1000mg | 2000mg | 3000mg | 4000mg | 5000mg |
| 30ml | 1200mg | 1500mg | 3000mg | 6000mg | 9000mg | 12,000mg | 15,000mg |
| 100ml | 4000mg | 5000mg | 10,000mg | 20,000mg | 30,000mg | 40,000mg | 50,000mg |
The next table shows the usual amount per millilitre and an estimated amount per drop. The drop calculation assumes 20 drops per ml. Real droppers vary, so the product label takes priority.
| Strength | 4% | 5% | 10% | 20% | 30% | 40% | 50% |
|---|---|---|---|---|---|---|---|
| Approx. CBD per drop | 2mg | 2.5mg | 5mg | 10mg | 15mg | 20mg | 25mg |
| CBD per ml | 40mg | 50mg | 100mg | 200mg | 300mg | 400mg | 500mg |
For a first oil, a lower amount per drop gives you more control. BioBloom 8%, Signature 15% and Biopurus 5% all allow smaller CBD increments than Love CBD's 16mg spray or Signature 50%'s 20mg CBD drop. Use our CBD strength guide and high-strength CBD oil comparison for more detail.
CBDa is the natural acidic precursor to CBD. Fresh and gently processed hemp tends to contain more CBDa. Heat gradually converts CBDa into CBD through a process called decarboxylation. This is why a raw whole-plant oil or hemp flower tea can show a different CBD-to-CBDa balance from a more heavily processed oil.
CBD and CBDa are distinct compounds. They should not be treated as interchangeable milligram for milligram, and early research into CBDa does not justify specific health promises. Our CBDa versus CBD guide explains the difference in ordinary language.
CBD oil supplies a measured amount in a few drops. Hemp tea adds a caffeine-free whole-plant drink to the routine and is usually richer in CBDa. We regularly recommend using the two alongside one another because the formats fit together well. We do not claim that the combination has been proved to treat a condition or guarantee an entourage effect.
Choose BioBloom organic tea bags for the easiest routine or BioBloom loose hemp flower tea for better value and control over the amount brewed.
Choose Biopurus 1.6% organic tea for an everyday brew or Biopurus 4% organic tea for a fuller, stronger-tasting infusion.
Follow the instructions for the tea, allow enough time to infuse and add milk or another small source of fat. Cannabinoids do not disperse readily in water, so a little fat makes more practical sense than drinking hemp tea completely plain.
The amount delivered by tea varies with the plant material, quantity, brewing time, temperature and added fat. Do not treat a cup as an exact serving. If a certificate reports CBD as well as CBDa, the CBD belongs within the total from all your CBD foods and supplements.
Compare the best hemp teas in the UK, read our complete hemp tea guide or browse the organic hemp tea collection.
Follow the instructions for your particular product because drops, pumps and sprays are not interchangeable.
Food can change swallowed CBD absorption considerably. Rather than moving between fasting and a large fatty meal, use the oil in a reasonably consistent way in relation to food. Our CBD bioavailability guide explains the evidence and its limits.
The old 70mg figure no longer applies to over-the-counter CBD foods and supplements. The FSA now advises healthy adults to limit CBD from these products to 10mg a day. This is precautionary advice based on average lifetime exposure. It does not mean that every exposure above 10mg causes harm.
The change makes the amount in one drop or spray much more important. Biopurus provides about 2.5mg CBD per drop. Signature 15% provides about 2.5mg CBD per drop alongside CBG and CBC. CannabiGold provides 10mg CBD per pump. Love CBD provides 16mg per spray and Signature 50% provides 20mg CBD per drop.
Read our current guide to CBD amounts and FSA advice.
The FSA says that greater lifetime intake increases the likelihood of long-term effects, including possible liver and thyroid changes. It advises the following groups not to take CBD unless under medical direction:
Possible unwanted effects can include digestive upset, dry mouth, appetite changes and drowsiness. CBD can also affect how some medicines are metabolised. Read our guides to CBD side effects and CBD and medicine interactions.
The full consumer advice is available from the Food Standards Agency.
CBD extracts used in foods and food supplements are treated as novel foods in Great Britain. Presence on the FSA public list is not approval or endorsement, and listed products have not necessarily completed a full safety assessment. Our UK CBD legality guide explains the position without sending you away to interpret the register yourself.
Full-spectrum oils can contain trace controlled cannabinoids within legal limits. Repeated use may still matter for somebody subject to workplace, sport or other drug testing. Read our CBD and drug-testing guide.
A comparison table can take you most of the way, but there are situations where a real conversation helps. We can explain what the percentage means, work out the amount in a drop or spray, compare the practical drawbacks and direct you to the relevant safety information.
We are an independent retailer rather than the owner of a single CBD brand. This means we can compare several formulations and say plainly when a lower strength, another format or no immediate purchase makes more sense. We have worked with CBD since 2016, use the oils ourselves and speak regularly with the people who make them.
Our help continues after an order. Customers contact us about drop calculations, strong flavours, oily pipettes, combining hemp tea with an oil and deciding which questions should be taken to a pharmacist. We explain what we can and say clearly when a question has become medical. Sensible boundaries are part of useful guidance.
We also make the supporting evidence easier to find. Product pages link to relevant certificates where they are available, while our guides explain milligrams, extract types, medicine interactions and current FSA advice in ordinary language. If a label or laboratory report is unclear, we would rather work through it with you than leave you to guess.
