Last updated: October 2026
The best CBD oil for sleep in the UK is broad spectrum (full spectrum contains THC; isolate is CBD alone), with 0% THC, a clear mg per drop, a batch lab report and a place on the FSA public list. CBD has no authorised health claims and isn’t a sleep treatment. Our Sleep and Broad Spectrum oils both qualify.
We make CBD oils, so we are not neutral. That is why this guide starts with a checklist you can use to judge any brand, including us, before showing our own picks.
Our two evening oils: Sleep CBD Oil is broad spectrum CBD with passion flower extract and a myrcene-led terpene blend, in 500mg or 1,000mg. Broad Spectrum CBD Oil is CBD and organic MCT oil only, in 500mg, 1,000mg or 2,000mg. Both have 0% THC, are on the FSA public list, vegan, made in the UK and tested by ISO 17025 accredited labs.

We make these, so judge them against the checklist below.
| Choose it if you want | Our pick | What you get |

| An evening blend with botanicals | Sleep CBD Oil | Broad spectrum CBD with passion flower extract and a myrcene-led terpene blend. 500mg or 1,000mg |

Does CBD help you sleep? The short version
The research is small and mixed. The trials below used between 15mg and 300mg of CBD a day, all above the FSA’s 10mg a day advice, and the results range from better sleep quality scores to no difference from placebo. A 2025 review that pooled six placebo-controlled trials found no clear effect for CBD on its own.
CBD isn’t a treatment for insomnia, and no CBD product can claim to be. For the trial-by-trial detail, read what the research says about CBD and sleep. The habits in how to sleep better still matter most, and if sleep problems last more than a few weeks, see insomnia and speak to your GP.
How to choose a CBD oil for sleep: the checklist
| Check | What good looks like | Why it matters |
|---|---|---|
| 1. Spectrum | Broad spectrum (other hemp compounds, no THC) or isolate (CBD on its own) | Full spectrum contains THC, a controlled drug in the UK that can affect drug tests |
| 2. No detectable THC | THC “not detected” on the lab report | The label alone is not enough |
| 3. Strength and mg per drop | Total mg, percentage and mg per drop on the label | So you know exactly how much you are taking |
| 4. Drops per 10mg | Easy maths: about 4 drops of a 5% oil, 2 of a 10% oil or 1 of a 20% oil | The FSA’s advice is based on 10mg a day |
| 5. Carrier oil | A simple, named carrier such as MCT oil | Fewer surprises, and easy to check for allergies |
| 6. Flavour and botanicals | Unflavoured, or extras listed by name (for example passion flower or myrcene) | Botanicals have no authorised health claims, so check what’s in the bottle and any cautions |
| 7. Batch lab report | An independent report for the batch you are buying | Confirms the CBD content and checks for contaminants |
| 8. FSA public list | The brand can tell you which application its product is linked to | Products not on the list should not be on sale in the UK |
| 9. Price per mg | Price divided by total mg of CBD | Bottle prices hide big differences in strength |
| 10. No medical claims | Honest wording, no promises to cure insomnia | Claims like that break UK rules and are a warning sign |
For the background, read is CBD legal in the UK? and how to read CBD lab results.

Red flags to avoid
- No lab report, or one that is years old or not for your batch
- Strength shown only as a big number with no mg per ml or per drop
- “Hemp oil” with no CBD content stated (it may be hemp seed oil, which contains little or no CBD)
- Promises to cure insomnia or “knock you out”
- CBD flower or buds, which are not legal in the UK
- Prices that look too good to be true: independent tests have found some CBD products contain much less CBD than their labels say
Oil vs capsules vs gummies vs drinks
| Format | Usually felt within | Pros | Cons |
|---|---|---|---|
| Oil (under the tongue) | 15 to 45 minutes | Fast, easy to adjust drop by drop | Earthy taste for some |
| Capsules | 1 to 2 hours | Exact amount, no taste | Slower, less flexible |
| Gummies | 45 minutes to 2 hours | Easy and tasty | Often low CBD per gummy, plus sugar |
| Drinks | 30 minutes to 2 hours | A nice evening ritual | Often small amounts of CBD per can |
For most people an oil is the most practical format for the evening, because you can fine-tune the amount. See CBD oil vs gummies and CBD oil vs capsules.
What strength CBD oil for sleep?
- 5% (500mg in 10ml): about 2.5mg per drop. The easiest place to start, since 4 drops is about 10mg.
- 10% (1,000mg in 10ml): about 5mg per drop. Suits people who already know they want more, and the bottle lasts longer.
- 20% (2,000mg in 10ml): about 10mg per drop. For experienced users only.
The FSA advises healthy adults to have no more than 10mg of CBD a day, which it puts at about 4 to 5 drops of a 5% oil.
The FSA’s 10mg a day figure is precautionary advice rather than a legal limit, set while longer-term safety research continues. At Evopure we think it is a very cautious figure, and many adults use more. If you go above it, increase slowly, and check with your GP or pharmacist first if you take any medication.
See our CBD dosage guide.
What type of CBD is best for sleep?
- Broad spectrum keeps other hemp compounds and terpenes but no THC. It’s the most popular choice in the UK.
- Full spectrum contains THC, which is controlled in the UK and can show up in drug tests. See full spectrum vs broad spectrum.
- Isolate is CBD on its own, with no taste. See what is CBD isolate?
- CBN “sleep” oils: CBN is often sold for sleep abroad, but it’s a controlled Class B drug in the UK and the research is early. See CBD vs CBN.
- Terpene blends: evening blends often use myrcene or linalool. Our Sleep CBD Oil uses a myrcene-led blend with passion flower; see passionflower for sleep.
Wondering about melatonin instead? It’s prescription-only in the UK. See CBD oil vs melatonin and melatonin in the UK.
How to compare prices fairly
Compare price per mg of CBD, not price per bottle. Divide the price by the total mg of CBD. A higher-strength bottle usually costs less per mg, and a cheap bottle with very little CBD can be poor value. Our guide to why CBD is expensive explains what goes into the price.
Our picks in detail
These are our own products, so judge them against the checklist above. All our CBD is broad spectrum with 0% THC, on the FSA public list and lab tested batch by batch, with reports available on request from our lab testing page.
Sleep CBD Oil with Passion Flower: our evening blend
Four ingredients: broad spectrum CBD, passion flower extract, coconut MCT oil and a terpene blend led by myrcene, with caryophyllene, terpinolene and alpha-pinene (no linalool or lavender). Available in 500mg (5%) and 1,000mg (10%), so 10mg is about 4 drops or 2 drops. Passion flower and terpenes have no authorised health claims: we list them so you know exactly what is in the bottle. See Sleep CBD Oil.
Broad Spectrum CBD Oil: the simple option
Two ingredients: broad spectrum CBD and organic MCT oil, with no flavourings or botanicals. Available in 500mg (5%), 1,000mg (10%) and 2,000mg (20%), at about 2.5mg, 5mg or 10mg per drop. A good choice if you prefer CBD on its own. See Broad Spectrum CBD Oil.
Magnesium Glycinate Sleep Complex: the non-CBD partner
A berry powder you stir into a drink before bed: magnesium bisglycinate and citrate with L-theanine, glycine and botanicals. Magnesium contributes to the normal functioning of the nervous system and the reduction of tiredness and fatigue. To compare forms, see our guide to the best magnesium for sleep. See Magnesium Sleep Complex.
Reishi cacao: the evening ritual
A warm reishi hot chocolate made with reishi mushroom extract, cacao, maca and coconut milk powder, if you like a warm drink in the evening. Cacao contains a little natural caffeine. See Reishi cacao.
Some people use Flow CBD Oil, with ashwagandha and maca, in the daytime and Sleep CBD Oil in the evening. Flow contains ashwagandha, so read who should avoid ashwagandha first.
How to use CBD oil in the evening
- Take it 30 to 60 minutes before bed, after your evening meal.
- Hold the drops under your tongue for about 60 seconds, then swallow.
- Start around 10mg and stay at that amount for a week or two.
- Keep the same bedtime and a short wind-down routine.
- Note how you sleep, and adjust slowly.
If you take any regular medication, especially sedatives or sleep medicines, speak to your GP or pharmacist first. Our products are for adults aged 18 and over. We don’t recommend our products during pregnancy or breastfeeding.

FAQs
What is the best CBD oil for sleep in the UK?
Look for a broad spectrum oil with no detectable THC, a batch lab report, a place on the FSA public list and a clear mg per drop. Some people prefer an evening blend with botanicals such as passion flower, others CBD on its own. CBD isn’t a sleep treatment.
What strength CBD oil is best for sleep?
A 5% oil (500mg in 10ml) is the easiest to start with, at about 2.5mg per drop. Higher strengths suit people who already know they want more.
How many drops of CBD oil is 10mg?
About 4 drops of a 5% oil, 2 drops of a 10% oil or 1 drop of a 20% oil. The FSA puts 10mg at about 4 to 5 drops of a 5% oil.
Is CBD oil or gummies better for sleep?
Oil is usually more practical because you can adjust the amount drop by drop. Gummies are convenient but often contain less CBD and added sugar.
What is the best CBD for sleep and anxiety?
CBD isn’t a treatment for sleep problems or anxiety, and no CBD product can claim to be. If you choose CBD as part of your routine, use the same checklist: broad spectrum, 0% THC, a batch lab report and a clear mg per drop. If anxiety or poor sleep affects daily life, speak to your GP.
Does the best CBD oil for sleep contain THC?
It shouldn’t. THC is a controlled drug in the UK. Choose broad spectrum or isolate oils with lab reports showing no detectable THC.
How long does it take for CBD oil to work for sleep?
Most people take drops 30 to 60 minutes before bed. CBD isn’t a sleep treatment and research results are mixed, so there is no set time for it to work. Keep a short sleep diary for a couple of weeks so you can judge your routine honestly.
Does CBD oil work for sleeping?
The research is mixed. Some small trials found better sleep quality scores, while others found no difference from placebo. CBD isn’t a treatment for insomnia, and good sleep habits matter most.
What type of CBD oil is best for sleep?
Most UK buyers choose broad spectrum, which has no THC. Evening blends add botanicals such as passion flower or terpenes such as myrcene. CBN oils are sold for sleep abroad, but CBN is a controlled drug in the UK.
Is CBN better than CBD for sleep?
There’s no good evidence that it is. A large 2024 trial found adding CBN to CBD made no difference, and CBN is a controlled Class B drug in the UK.
Can I take CBD oil and magnesium together for sleep?
Yes, many people do. Magnesium contributes to the normal functioning of the nervous system. If you take regular medicines, check with your pharmacist first.
