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.

Learn About CBD

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.
