How to Use CBD Isolate
CBD isolate is the purest form of CBD you can buy: a fine white powder that’s around 99% pure CBD and nothing else. No THC, no other plant compounds, no taste. That purity is exactly what makes it so versatile, whether you want to make your own oil, stir it into food, or add it to your own skincare. Here’s how to use it, and how to get your measurements right.

What is CBD isolate?
CBD isolate is cannabidiol (CBD) refined down to its purest form, usually around 99%. It’s extracted from hemp and then stripped of everything else, including THC, terpenes and the other natural plant compounds. What you’re left with is a flavourless, odourless crystalline powder that’s easy to measure and easy to mix into almost anything.
Because it contains no THC, isolate is a popular choice for anyone who wants to steer clear of THC completely, including people who are subject to drug testing at work.
Why people choose CBD isolate
- It’s completely THC-free. Pure CBD with nothing else, so there’s no THC to think about.
- Dosing is precise. You can measure it right down to the milligram. As a rough guide, 1mg of isolate is about 1mg of CBD.
- It’s versatile. Use it on its own, or mix it into oils, food, drinks or your own skincare.
- There’s no taste or smell. Handy if you’re not keen on the natural, earthy flavour of hemp.
- It’s good value. A little goes a long way, so the cost per dose works out low.
How to use CBD isolate
Isolate is one of the most flexible CBD products out there. Here are the most common ways people use it.
1. Under the tongue
One of the quickest ways to take isolate is to place it under your tongue. Measure out your dose (a lot of people start somewhere around 5 to 10mg), pop the powder under your tongue, hold it there for 60 to 90 seconds, then swallow. Taking it this way lets it absorb through the tissue under your tongue. If you’d like more detail, we’ve written a full guide to taking CBD under the tongue.
2. Mixed into food and drinks
Because it’s flavourless, isolate is easy to add to food and drink. Stir it into a smoothie, juice or coffee, mix it into a salad dressing or sauce (add it after cooking rather than during), or bake it into things like flapjacks. Just avoid very high heat, and measure carefully so you always know your dose.
3. Make your own CBD oil
You can make your own oil at home with nothing more than isolate and a carrier oil. Mix 1000mg of isolate with 30ml of a carrier oil such as MCT, olive or hemp seed oil, and you’ll have roughly a 33mg per ml strength. Shake it well, keep it somewhere cool and dark, and use it under the tongue or in recipes.
4. Make your own skincare
Isolate can be stirred into homemade balms, salves and lotions. Gently melt a spoonful or two of shea butter or coconut oil, stir in your isolate, let it set, and it’s ready to use on the skin.
5. Vaping or dabbing
For people who already vape or dab, isolate can be vaporised. Options include dabbing it with a rig, mixing it with terpenes (sometimes called “terpsolate”) for flavour, or adding it to a compatible vape juice. This one is really aimed at experienced users with the right equipment.
6. For pets
Some owners like to add CBD to their pet’s routine. There is no difference between pet CBD and the CBD people take: it is the same cannabidiol, usually weaker and dearer per mg under a pet label, and plenty of our customers use our range with their animals. Isolate has the advantage of containing no THC, which animals are more sensitive to than people. Always speak to your vet first, especially if your pet takes any other medication.

Getting your dose right
The nice thing about isolate is how easy it is to be accurate. A few pointers:
- Use a digital micro-scale so you can measure small amounts precisely.
- Start low and build up slowly, especially if you’re new to CBD.
- Keep a simple note of how much you take and when, so you can find what suits you.
- Be consistent, and give it a bit of time.

CBD isolate FAQs
How much CBD isolate should I take?
There’s no one-size-fits-all amount. A lot of people start low, around 5 to 10mg, and build up slowly until they find what suits them. Because isolate is so easy to measure, you can be precise, so if you’re unsure, start small.
What’s the difference between CBD isolate and full-spectrum?
CBD isolate is pure CBD with everything else removed, including THC. Full-spectrum keeps the full range of naturally occurring cannabinoids and terpenes from the hemp plant, with only trace THC. Neither is better as such; it comes down to whether you want pure CBD or the whole plant profile.
Will CBD isolate show up on a drug test?
CBD isolate is THC-free, so it shouldn’t. That said, always buy from a reputable supplier who can stand behind the THC-free claim, as quality varies across the market.
Does CBD isolate have a taste?
No. It’s flavourless and odourless, which is exactly why it’s so easy to mix into food, drinks or your own products.
How should I store CBD isolate?
Keep it in a cool, dry place away from direct sunlight, and out of reach of children. Stored properly, it keeps well.
Is CBD isolate right for you?
CBD isolate gives you a clean, precise and flexible way to take CBD, with no THC and no taste.
