500mg CBD oil is a bottle holding 500mg of CBD in total, not in each dose. In a 10ml bottle that is 5%, or 50mg of CBD per ml, so 10mg of CBD is about 0.2ml and the bottle gives about 50 servings of 10mg. Evopure’s Broad Spectrum CBD Oil 500mg is our best-selling oil.
In a 30ml bottle, 500mg is only 1.67%, so 10mg of CBD is about 0.6ml. That is why the ml on the label matters as much as the mg. 500mg is a starting strength, and it makes the FSA’s advice of no more than 10mg a day easy to measure.
What does 500mg CBD oil mean?
500mg CBD oil means the whole bottle contains 500mg of CBD. It is not a dose. To know how strong the oil is, divide the mg by the ml: 500mg in 10ml is 50mg of CBD per ml (5%), while 500mg in 30ml is about 17mg per ml (1.67%). The smaller bottle is three times stronger per ml.
| Bottle | % CBD | mg per ml | 10mg of CBD is about |
|---|---|---|---|
| 500mg in 10ml | 5% | 50mg | 0.2ml |
| 500mg in 30ml | 1.67% | About 17mg | 0.6ml |
| For comparison: 1,000mg in 10ml | 10% | 100mg | 0.1ml |
| For comparison: 2,000mg in 10ml | 20% | 200mg | 0.05ml |
Quick formula: % strength is total mg ÷ ml ÷ 10, and the ml for 10mg is 10 ÷ mg per ml. Our CBD oil strength guide covers every strength side by side.

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.
Which Evopure 500mg CBD oil fits your routine?
Every 10ml Evopure oil comes in 500mg, and so do our 30ml Evolabs flavoured oils. Checked against our product pages in November 2026:
| Oil | Bottle | 10mg of CBD is about | Good if you want |
|---|---|---|---|
| Broad Spectrum CBD Oil | 10ml, 5% | 0.2ml | Plain CBD in coconut MCT oil, unflavoured |
| Flow CBD Oil | 10ml, 5% | 0.2ml | A daytime blend with ashwagandha and maca |
| Sleep CBD Oil | 10ml, 5% | 0.2ml | An evening blend with passionflower |
| Relief CBD Oil | 10ml, 5% | 0.2ml | A blend with turmeric and black pepper |
| Evolabs Natural, Orange or Cherry | 30ml, 1.67% | 0.6ml | A bigger bottle and a flavour; CBD, THC free |
Flow contains ashwagandha, which isn’t suitable during pregnancy or breastfeeding, or for people with thyroid, liver or autoimmune conditions. The Evolabs Mint oil with vitamin D3 comes in 1,000mg only, so it isn’t a 500mg option.
They’re food supplements, not medicines, and they make no health claims. Every Evopure CBD batch is tested at ISO 17025 labs, and you can request your batch report on our lab testing page.
How much 500mg CBD oil is 10mg?
10mg of CBD is about 0.2ml of a 500mg oil in a 10ml bottle, because each ml holds 50mg of CBD (10 ÷ 50 = 0.2). In a 30ml bottle each ml holds about 17mg, so 10mg is about 0.6ml. Measure in ml, because the amount that comes out of a dropper varies from bottle to bottle.
- 10ml bottle (5%): 500mg ÷ 10ml = 50mg per ml, so 10mg is about 0.2ml.
- 30ml bottle (1.67%): 500mg ÷ 30ml = about 17mg per ml, so 10mg is about 0.6ml.
- A full 1ml of a 10ml 500mg oil is 50mg of CBD, five times the FSA’s 10mg.
Hold the oil under your tongue for 60 to 90 seconds, then swallow. Our guide to how to take CBD oil walks through each step, and the CBD dosage guide has a 10mg chart in ml for every Evopure oil. If you’d like to choose a time of day, see when to take CBD oil.
Is 500mg CBD oil strong?
No. 500mg CBD oil is a lower, starting strength. In a 10ml bottle it is 5%, and in a 30ml bottle only 1.67%. That makes it easy to measure 10mg, the FSA’s advised daily maximum for healthy adults, and to adjust in small steps. Strength is about mg per ml, not about how well an oil works.
| Strength in 10ml | % CBD | 10mg of CBD is about | Usually described as |
|---|---|---|---|
| 500mg | 5% | 0.2ml | Low or starting strength |
| 1,000mg | 10% | 0.1ml | Medium strength |
| 2,000mg | 20% | 0.05ml | High strength |
A stronger bottle doesn’t mean you should take more. The FSA’s 10mg figure is about the amount you take each day, not the strength of the bottle. Its scientific committees name liver effects and sleepiness as the main concerns at higher intakes (see is CBD bad for your liver?), and our view on the figure is in CBD daily limit in the UK.
Ready for the next strength up? Our 1000mg CBD oil guide shows how 10mg becomes about 0.1ml and why that bottle lasts about 100 days. Already know your amount and want even less oil each day? A 2000mg CBD oil gives 10mg in about 0.05ml, though that is a very small amount to measure.
How long does a 500mg CBD oil last?
At 10mg a day, a 500mg bottle lasts about 50 days, whether it is 10ml or 30ml (500 ÷ 10 = 50). The bottle size only changes how much oil you take each time: about 0.2ml from a 10ml bottle or about 0.6ml from a 30ml bottle.
| Daily amount | 10ml, 5% | 30ml, 1.67% | Bottle lasts |
|---|---|---|---|
| 10mg (the FSA’s advice) | About 0.2ml | About 0.6ml | About 50 days |
| 20mg | About 0.4ml | About 1.2ml | About 25 days |
About 50 days also suits freshness. Once opened, it is best to finish an oil within a few months, so a 500mg bottle used daily never sits around for long. Keep it upright, capped and in its box in a cool, dark cupboard: see how to store CBD oil for shelf life and the signs an oil has gone off.
On cost, bigger strengths usually work out cheaper per mg, while 500mg costs least to try. Our best value CBD oil UK guide works out the cost per 10mg of each strength, and Subscribe and save lowers the price of every order.
How to choose a 500mg CBD oil in the UK
Check five things before you buy. In a 2022 analysis of 29 UK CBD products, only 11 were within 10% of the CBD stated on the label, so the paperwork matters.
- The ml as well as the mg. 500mg in 10ml (5%) and 500mg in 30ml (1.67%) need different amounts for 10mg.
- THC. Broad spectrum oils have the THC removed; full spectrum oils keep traces. The Home Office limit is no more than 1mg of controlled cannabinoids in the whole product. See full spectrum vs broad spectrum CBD oil.
- A batch lab report showing about 50mg of CBD per ml for a 10ml 500mg oil and THC “not detected”. Our guide to reading a CBD lab report explains each line.
- The FSA public list. CBD food products on sale in England and Wales should be linked to a novel food application on the list. Every Evopure CBD product is on it.
- The carrier oil and flavour. MCT oil is light and plain; flavoured oils can help if you dislike the earthy taste.
Choosing between oil and capsules? CBD oil vs capsules compares them, and is CBD legal in the UK? covers the rules.
The FSA doesn’t advise CBD during pregnancy or breastfeeding, for under-18s, or for people taking medication unless under medical direction. CBD can change how some medicines are broken down: see can CBD interact with medication?
Next step
start with Broad Spectrum CBD Oil 500mg, where about 0.2ml gives 10mg of CBD and one bottle lasts about 50 days at that amount. Prefer no measuring? One 10mg capsule a day does the same job.
