The best CBD oil for sleep is a broad spectrum oil with no detectable THC, an up-to-date lab report for every batch, a place on the FSA public list and a strength you can measure easily. Blends with evening botanicals such as passionflower suit people who struggle to switch off. Start around 10mg, 30 to 60 minutes before bed.
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.
How to choose the best CBD oil for sleep: the 7-point checklist
| Check | What good looks like | Why it matters |
|---|---|---|
| 1. 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 |
| 2. Batch lab report | An independent report for the batch you are buying | Confirms the CBD content and checks for contaminants |
| 3. No detectable THC | Broad spectrum or isolate, with THC “not detected” | THC is a controlled drug and can affect drug tests |
| 4. Clear strength | Total mg, percentage and mg per drop on the label | So you know exactly how much you are taking |
| 5. Simple ingredients | A short list you understand: CBD, a carrier oil, any botanicals | Fewer surprises, easier to spot what suits you |
| 6. Evening extras (optional) | Passionflower, chamomile or calming terpenes such as myrcene | Popular in blends made for night-time |
| 7. 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 for sleep
| 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 dose, 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 best format for sleep 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% (1000mg in 10ml): about 5mg per drop. Suits people who already know they want more, and the bottle lasts longer.
- 20% (2000mg in 10ml): about 10mg per drop. For experienced users only.
The FSA’s precautionary advice is no more than 10mg of CBD a day for healthy adults. That 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.
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 for sleep
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 on our lab testing page.
Sleep CBD Oil with Passion Flower: for a busy mind at night
Four ingredients: broad spectrum CBD, passionflower extract, coconut MCT oil and a myrcene-led terpene blend. Available in 500mg (5%) and 1000mg (10%). Take it about an hour before bed, every night for at least ten days before you judge it. See Sleep CBD Oil.
Broad Spectrum CBD Oil: the simple option
Broad spectrum CBD in MCT oil, nothing else added, in 500mg, 1000mg and 2000mg. A good choice if you prefer no botanicals. 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. See Magnesium Sleep Complex.
Reishi cacao: the evening ritual
A warm reishi hot chocolate for winding down, especially if you are cutting back on an evening drink. See Reishi cacao.
If daytime stress is what keeps you awake, some people take Flow CBD Oil in the morning and Sleep CBD Oil at night. Flow contains ashwagandha, so read who should avoid ashwagandha first.
How to use CBD oil for sleep
- Take it 30 to 60 minutes before bed, after your evening meal.
