CBD Oil vs Capsules: Which Is Best? Speed, Absorption and Value (UK)

Which to buy: CBD oil or capsules?

Pick by how you like to take it. Here are our three main options, checked against our product pages in November 2026.

The oil also comes in 1,000mg and 2,000mg, and the capsules in 25mg: choose those on the oil or capsules page. One Evolabs capsule is three times the FSA’s 10mg a day figure (see below), so it’s for people who already know their amount. All three have 0% THC on the batch report, are vegan and are on the FSA public list, linked to validated applications. They’re food supplements, not medicines.

What is CBD oil?

CBD oil is a hemp extract mixed into a carrier oil, usually MCT oil from coconut, which CBD dissolves in. You place drops under your tongue, hold them for about a minute, then swallow. Some CBD may be absorbed through the lining of the mouth, but most is swallowed and digested. Oils come in different strengths, measured in mg of CBD per bottle. See CBD oil strength explained, how to take CBD oil and why we use MCT in MCT vs hemp seed vs olive oil.

Our Broad Spectrum CBD Oil has just two ingredients: broad spectrum CBD and organic MCT oil. If you’d rather a flavour, our Evolabs oils come in orange, cherry, mint (with vegan vitamin D3) and natural, in 30ml bottles.

What are CBD capsules?

CBD capsules hold a fixed amount of CBD in a capsule or softgel shell, often 10mg or 25mg. You swallow them like any other supplement, so there’s no taste and no measuring. All the CBD is digested, which is how most of the CBD in an oil ends up being absorbed too.

Our Broad Spectrum CBD Capsules contain broad spectrum CBD (10mg or 25mg) with inulin, a plant fibre, in a size 3 HPMC capsule. HPMC is a plant cellulose shell, so there’s no gelatin and the capsules are vegan. Each jar holds 30. More on checking labels in is CBD oil vegan?

Absorption and speed: what the research shows

Bioavailability is the share of CBD that reaches your bloodstream. You’ll often see confident claims that oil absorbs two or three times better than capsules. The evidence doesn’t back that up. A 2018 systematic review of human studies found too little data to pin down CBD’s bioavailability when taken by mouth or under the tongue.

The best direct comparison comes from Loughborough University. Researchers gave eight healthy men the same CBD oil, once as drops under the tongue and once inside swallowed capsules. Blood CBD levels, the peak level and the time to peak (about 4 hours) were the same with both. The authors concluded that oil held under the tongue is mostly swallowed before much can be absorbed through the mouth.

What that means for you:

• Speed: on blood tests, drops and capsules peaked at the same time, about 4 hours after a dose, in line with a review that found CBD taken by mouth typically peaks within about 0 to 4 hours. Holding drops under the tongue for a minute does no harm, but most of the oil is swallowed. People’s experiences vary, so judge either format over a couple of weeks. See how long CBD takes to work.
• First-pass metabolism: swallowed CBD passes through the liver, which breaks some of it down before it reaches the rest of the body. This affects swallowed oil and capsules alike.
• Consistency beats format: CBD builds up with regular use. In a trial in healthy adults, blood levels reached a steady state after about 2 days of twice-daily dosing, with about half cleared in 10 to 17 hours.
• Small study, open question: eight people is a small group, so a modest difference in some people can’t be ruled out.

Which is stronger, CBD oil or capsules?

Neither. Strength is the mg of CBD in each dose, not the format. A 10mg capsule and 10mg of oil contain the same amount of CBD, and the head-to-head study above found similar blood levels from each.

Where oil does differ is range. Our oils go up to 2000mg in 10ml, about 10mg per drop, so you can take a little or a lot without swallowing several capsules. Our capsules come in 10mg and 25mg. The type of extract matters more than the format: all Evopure oils and capsules are broad spectrum with 0% THC. See full spectrum vs broad spectrum vs isolate.

Take CBD with food: the tip most people miss

CBD dissolves in fat, and taking it with a meal makes a far bigger difference than oil versus capsules. In a controlled trial in healthy adults, a high-fat meal raised total CBD in the blood about 4.2 times and the peak level about 4.85 times compared with fasting. A separate study of CBD capsules found total exposure about 4 times higher, and the peak about 14 times higher, after a high-fat breakfast.

Both studies used much larger doses than a food supplement, so the exact numbers may not carry over, but the direction is clear. In practice, take your oil or capsules with or just after a meal that contains some fat, such as breakfast with eggs, yoghurt or avocado, or your evening meal. Do it the same way each day so your results are consistent. For ideas, see cooking with CBD oil.

How many drops or capsules make 10mg?

A standard dropper gives roughly 20 drops per ml. Divide the bottle’s mg by its ml, then by 20, to get mg per drop. Here is how our products work out:

Drop sizes vary a little between droppers, so treat these as close estimates. For the full chart and starting amounts, see our CBD dosage guide.

Which is better value?

Compare the cost per 10mg serving rather than per bottle or jar: divide the price by the number of servings in the table above. Because a 2000mg oil holds about 200 servings of 10mg and a jar of 10mg capsules holds 30, higher-strength oils almost always work out cheaper per mg. Capsules cost a little more for the convenience of a pre-measured dose.

Across our range, the Evolabs 2000mg oils are the lowest price per mg. If you prefer capsules, our Evolabs 1500mg capsules (50 x 30mg) are the value option. For more on pricing, see why CBD oil costs what it does.

Oil or capsules for evenings, busy days and daily use

• For an evening routine: oil or a capsule with your evening meal works well, since CBD is best taken with food. Our Sleep CBD Oil adds passion flower and a myrcene-led terpene blend. CBD isn’t a treatment for sleep problems; for what the research shows, see CBD for sleep.
• For busy days: capsules are easy to take at your desk or on the go. If you like to vary your amount from day to day, oil is easier. See CBD oil and anxiety: how to choose.
• For steady daily use: capsules with breakfast make it easy to stay consistent, and consistency matters more than format.
• For travel: capsules are simplest. Check the rules for your destination in can you take CBD oil on a plane?

Can you take CBD oil and capsules together?

Yes. Many people take a capsule in the morning and oil in the evening, or keep capsules for days out. Just add up your total CBD across both: a 10mg capsule plus 2 drops of a 1000mg oil is about 20mg. 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 what the FSA’s 10mg advice really means, and try both formats together in our bundle builder.

Who shouldn’t take CBD oil or capsules

The same safety advice applies to both formats. Our CBD products are for adults (18+) only. We don’t recommend our products during pregnancy or breastfeeding; see CBD in pregnancy. The FSA also advises people taking prescription medication to avoid CBD without medical advice, because CBD can interact with some medicines; see can CBD interact with medication? If you notice side effects, lower the amount or stop. More in CBD side effects.

Final thoughts on CBD oil vs capsules

It comes down to your routine. Choose oil if you want to find your amount, use a higher strength or get the best value per mg; choose capsules if you want simplicity and no taste. Whichever you pick, take it with food, at the same time each day, and give it a few weeks.
