What is CBD?

CBD, or cannabidiol, is a compound extracted from the cannabis plant known as a cannabinoid. There are over 100 cannabinoids that we know and these are capable of interacting with the human endocannabinoid system. This is a system of neurotransmitters and receptors found throughout the body. It helps to regulate systems and processes within the body, including appetite, inflammation and pain response.

THC is another cannabinoid you may already be aware of. This is the psychoactive compound in cannabis known for producing the “high” effect, which is why it is a controlled substance. While THC suppresses the function of the endocannabinoid system, CBD supports it. This is why CBD isolate is commonly used to support an active and healthy lifestyle.



Pure and Honest CBD

Pure Isolate

CBD isolate is the purest form of CBD available to buy online in the UK. By focusing on purity, we can provide a premium CBD experience for those who wish to avoid all traces of THC.

the free


All of our CBD isolate products are completely free from THC, which makes them suitable for those seeking a completely safe and legal CBD product. CBD isolate is the purest CBD product available.  Any trace of THC within health and wellbeing products in the UK is deemed illegal and our proprietary technology ensures full compliance with UK regulation.

triple lab tested


All of our CBD isolate products undergo extensive testing at ISO 17025 accredited testing facilities in the UK. Triple lab testing ensures you get to enjoy a superior product free from THC, any contaminants or any controlled substances.  By removing the entourage or ‘head high’ effect of THC our customers can enjoy the pure benefits of CBD.



Our CBD isolate products are certified cruelty free and do not contain any animal-derived ingredients. All of our CBD isolate products are suitable for those following a vegan lifestyle and we are proud to support the vegan lifestyle.

gluten free


All ISO CBD products are gluten-free, meaning they can be enjoyed by those living with coeliac disease or gluten intolerances. Paying close attention to our supply chain ensures no risk of contamination and enables our loyal customer base to enjoy CBD isolate and its many physical, mental and spiritual benefits.

made in the uk


Our oils and tinctures are all made in the UK using pure CBD isolate. The purity of our CBD extracts ensures premium quality and a reliable and consistent user experience.

ultrasonic technology


Our CBD isolate product range is unique due to the proprietary ultrasonic technology we use to ensure market leading bioavailability and absorption levels across our CBD isolate product range.  Simply put, the higher the bioavailability the better the absorption in the body will be.  Our products are believed to have bioavaility rates 5-7 times more effective than the market standard meaning that less product is needed to achieve similar results giving our customers a maximum bang for their buck.

premium oils


ISO CBD ensures the use of only the finest C8 grade MTC oils for our CBD isolate oils and tinctures.  This is crucial in ensuring that we can deliver the highest levels of bioavailability and absorption for our customers.  High-quality MCT oil is a powerful way to upgrade your brain. This is because C8 MCT oil turns into ketones within minutes. Ketones quickly cross the blood-brain barrier and can be used as a fuel source for brain cells, giving you steady energy.

value for money


ISO CBD’s main mission is not only to educate and raise awareness of the numerous benefits of using CBD isolate to the public but we are also committed to providing the best value for our customers.  In addition to offering customers 5-7 times greater bioavailability across our CBD isolate product range, we are also priced at a 50% discount to the average market price for similar products. Essentially, ISO CBD products provide you with up to 10 times more value for your money.

novel food


ISO CBD was founded to ensure fully legal and compliant CBD isolate products were available in the UK market. We are proud to confirm that as of 31st March, 2022 our entire product range has been added to the Novel Foods Register which enables us to sell products in the UK legally. We are working with the FSA to ensure full validation and authorisation for the future. This is a very exciting time for the CBD industry and we are proud to ensure only high quality, safe and stable products are available to all our customers.

How do you take CBD?



CBD oral drops offer the simplest and most accessible way to enjoy CBD. You simply drop the carrier oil containing CBD isolate compounds under your tongue and leave it for a few minutes. If there is any residue left after this time, you can simply swallow it.

CBD Tablets

Another popular way to enjoy CBD is with CBD tablets. These might be chewable or intended to be swallowed like a vitamin. If you are looking for a simple and precise way to enjoy CBD, this method is ideal.


CBD Topicals

CBD is also excellent when added to skincare items. It may be added to moisturisers and oils to help with problem skin. It’s also excellent as a muscle balm to help with painful joints and muscles. Or it could be added to bath bombs and massage oils for a relaxing treat.

Learn About CBD

What is CBD Isolate?

When extracting CBD from the cannabis plant, it isn’t the only plant compound that is removed. There are other cannabinoids, terpenes and flavonoids that make up the finished product. Full-spectrum CBD products contain everything, including legal levels of THC. Broad-spectrum CBD contains everything, but with the THC removed. And CBD isolate contains only CBD. 

CBD isolate is the purest form of CBD available on the market and is extracted with a purity of up to 99.9%. CBD isolate is achieved by singularly extracting it from its source and then isolating the compound from its accompanying cannabinoids. CBD isolate comes as a white powder that can be mixed with a carrier oil. We use MCT oil in ISO CBD products as it offers better absorption rates while also offering additional health benefits.

Full-spectrum CBD contains all the cannabinoids and other substances from the hemp plant, including controlled substances and psychoactive ingredients including THC and CBN. The presence of these additional cannabinoids in full-spectrum CBD products helps to create “the entourage effect”. Isolate-based products such as the ISO CBD range allow users to easily ingest specific quantities of CBD and control the dosage without having to worry about THC levels or any other controlled substances.

How much CBD oil should you take?

There is no standard dosing for CBD products as it is not a medicine intended to treat or cure. The FSA recommends that adults do not exceed more than 70mg of CBD oil per day. This would be a very high dosage, and most people will take far less than this. When you buy CBD isolate products from ISO CBD, you can guarantee that the CBD dose will be the same between batches and between drops. This makes it far easier to keep track of how much CBD you have taken throughout the day.


Most people start with a 500mg CBD isolate oil to start. Our CBD oils come with a handy measuring pipette in the lid. A 1ml dropper of oil contains around 17mg of CBD oil. Most people start with a single dose per day and monitor the results. You can then increase the dosage until you reach the desired effect. If you accidentally take too much CBD, the side effects will not last for very long. You might have a dry mouth, nausea and feel more sleepy than usual.

Who can take CBD?

CBD isolate is an ideal addition to a healthy lifestyle. It is recommended for adults who are looking for a simple way to boost their health and wellbeing. CBD isolate is not a medicine and should never be sold as a cure or treatment for any condition. Instead, it should be seen as a supplement that you take regularly to help boost your health and wellbeing. Similar to a vitamin supplement, CBD is best taken regularly, which is why we recommend adding it to your daily routine.


You can take CBD in the morning to help start your day or take it in the evening to help you to wind down and get a good night’s sleep. You can add our CBD isolate oils to hot drinks or smoothies, or even create delicious recipes. CBD is also an excellent addition to your fitness programme, allowing you to manage rest days and ensure you recover effectively to enhance performance. It may also help you with specific health conditions, including those linked to inflammation and pain. Although it is not a medicine and cannot cure or treat specific conditions, it is an excellent supplement to consider for overall health and wellbeing.


Where does CBD come from?

CBD comes from the cannabis or hemp plant. These plants can be grown for commercial reasons, provided the THC content at the time of harvest is sufficiently low. Once the plants have been harvested, the process of extracting the cannabinoids can begin. The best extraction method is known as supercritical CO2 extraction, which leaves behind no residue and is highly effective.


Once the cannabinoids have been extracted, it’s time to isolate the CBD from the rest of the plant compounds. Isolating the CBD helps to ensure the final product is pure and free from contaminants, THC and other plant compounds. This results in a more stable and reliable product that customers can trust. Every drop of CBD isolate oil contains the same amount of CBD and the ingredients are identical between batches.

Why is ISO CBD different?

We produce small-batch CBD isolate which results in a superior CBD oil. Our CBD is also subject to a process of nanoemulsion which breaks the compound into nanoparticles. This helps to increase the dispersion rate, which in turn helps to increase the bioavailability of our products. Higher bioavailability means that more of the product can be used by your body and less is filtered out by the liver.

This is a medical-grade approach to CBD production that helps to create a stable and reliable product. With large-scale production of full and broad-spectrum CBD products, the finished product can be vastly different between batches. When you buy CBD isolate made in smaller batches, the product remains the same, so you never have to adjust your dosage. You can also rely on getting the same amount of CBD per dose, making it a lot more reliable.

The Science of Dispersion

There are many different ways to take CBD products, and they all result in different absorption rates. When you take CBD drops under your tongue or chew CBD tablets, the CBD compounds are absorbed through the small blood vessels under your tongue. The rest is swallowed, where it is absorbed through the lining of the digestive tract. A small amount is filtered out by the liver as waste and is never used. 


The amount of CBD available to your body when you take it is known as bioavailability. Without clinical trials to confirm the bioavailability of a product, we have to look for other methods that will confirm the quality of a product. Dispersion is one such method. Dispersion refers to the distribution of the CBD compounds within the carrier oil. 


If the CBD is not able to effectively disperse within the carrier oil, then the CBD content between batches, bottles and even doses could vary dramatically. Our process of nanoemulsion makes the CBD particles smaller, which allows them to disperse in the mixer oil more effectively. And this in turn helps to increase the bioavailability by ensuring more of the product is absorbed in the mouth.

This includes CBD isolate oils and CBD tablets. By focusing on CBD isolate products only, we can offer a reliable and trusted source of CBD products to add to your daily routine.
