When we send someone their first bottle, the question that comes back most often isn't about strength or flavour. It's "am I actually taking this right?" Fair question, because the right way looks slightly odd, and it makes a real difference.
What does taking CBD oil "sublingually" actually mean?
Sublingual just means under the tongue. You drop the oil there, hold it without swallowing, then swallow what's left. That's the whole technique. The only skill involved is patience, and the only equipment is the dropper in the bottle.
Aim for around 60 seconds; anything over about 30 puts you in a good spot. I time mine by singing "Happy Birthday" in my head, a habit that stuck from all the hand-washing back in 2020. The thing to avoid is a quick 5-second dab and swallow, which is too short for the oil to absorb properly. It helps to hold off on your tea or coffee for a few minutes afterwards so you're not rinsing the oil away before it's done its job. Most people tack it onto something they already do every day; I take mine last thing at night, before bed.
Why under the tongue rather than just swallowing it?
Because swallowed CBD takes the scenic route. When you swallow it, it travels through your stomach and liver first, and the liver breaks a good deal of it down before it ever reaches your blood, so less of what you took actually counts. Held under your tongue, CBD absorbs directly through the thin tissue there and goes straight into your bloodstream, skipping that whole process.
Sublingual CBD skips the digestive queue and absorbs straight into your bloodstream.
The difference is twofold. It's faster, and it's less wasteful, because a greater share of each dose reaches your system rather than being lost along the way. A 2018 systematic review of how the body processes CBD found that swallowing it gives notoriously low and variable absorption, which is a large part of why holding it under the tongue is worth the slightly awkward minute.
Our CBD oil dropper, where precision matters.
How long does it take to work, and how long does it last?
Two different questions, so let's take them in turn. Onset, meaning how long before you notice anything, is usually 15 to 30 minutes when you take the oil under your tongue. Duration, meaning how long the sensation then stays with you, tends to be around 4 to 6 hours. Swallowing the oil instead pushes that onset out to an hour or 2, because it has to work through your digestive system first.
Those numbers are a guide, not a promise. How quickly you feel it, and how long it stays, depends on your metabolism, the strength of the oil, whether you've just eaten, and how long you held it under your tongue. If nothing seems to happen the first time, that's normal, and it isn't a reason to double up straight away.
How much should I take?
Start low and give it time. Everyone's different, so the right amount depends on your body weight, your metabolism and, honestly, what feels right for you. Begin with a small daily amount, stay there for a few days, and only increase gradually if you feel you'd like to. Follow the dosage guidance on your product's label, and if you take any regular medication, have a word with your GP first.
It's worth keeping a simple note of when you take it and how you find it, not because there's a perfect dose to chase, but because it helps you settle on the amount and timing that suit your day.

What does it actually feel like?
Gently is the honest answer. CBD isn't intoxicating; there's no high, no head-rush, nothing to "kick in". Some people find it becomes a quiet part of how they wind down in the evening, or a small ritual before a busy day. Early research is still working out what CBD does and doesn't do, and we'd rather be straight with you about that than promise the moon.
Our oil is broad spectrum, which means it keeps the wider range of natural compounds and terpenes from the hemp plant alongside the CBD, with the THC removed. Some researchers think these compounds may work better together than CBD does on its own, an idea often called the entourage effect. It's a promising theory rather than a settled fact, but it's why we make a broad-spectrum oil rather than a plain isolate.
Is it safe, and how should I look after the bottle?
For most healthy adults, CBD is well tolerated. A 2017 review of its safety found the main things to be aware of are mild and usually temporary, such as a dry mouth, a little drowsiness or a change in appetite. The World Health Organization's 2018 assessment reached a similar conclusion about its general safety profile.
Two sensible cautions. CBD can interact with certain medications, particularly those processed by the same liver enzymes (the cytochrome P450 system) that handle drugs like some blood thinners and antidepressants, so check with your GP or pharmacist before starting if you take anything regularly. And if you're pregnant or breastfeeding, it's best to wait and speak to a professional first.
Looking after the oil is easy: keep the bottle somewhere cool and dark, away from direct sun and radiators, with the lid firmly on. A kitchen cupboard is perfect. Stored well, it keeps its quality for the life of the bottle; there's no need to refrigerate it.
CBD is a food supplement, not a medicine. It isn't intended to treat, cure or prevent any condition. If you're pregnant, breastfeeding or taking medication, talk to your doctor before trying it.
