In a previous article, we talked about the importance of bio-availability and why you should vape CBD. You can read all about that here. When you hunt around for cheap CBD, you might think you are getting a bargain but is your CBD good value for money? In this post, we will apply the bio-availability of different methods of administering CBD to see if your great deal on CBD is actually what it seems.
If you have specific questions about CBD, they’re most likely covered in our official CBD Guide.
Bio-availability for different types of CBD
CBD is available in various forms, including edibles, tinctures, oils and e-liquid. Each form means the administration method changes. Edibles are ingested (i.e. absorbed through the gastrointestinal tract), tinctures and oils are sublingually administered (i.e. absorbed under the tongue), and e-liquids are inhaled/vaped (i.e. absorbed through the lungs).
Each administration method changes the way and how much CBD is absorbed into the blood, i.e. bio-availability.
The lower the bio-availability, the more CBD is wasted.
There has been plenty of research conducted on the bio-availability of the different types and administration methods of CBD.
According to the World Health Organization (WHO) in its 2018 report, the bio-availability of ingested CBD is as low as 6%. This means that as much as 94% of the CBD you bought is not even absorbed by your body. The reason for this is that ingesting substances subjects them to extensive first-pass metabolism by the liver.
Sublingual administration fares better with a 30% CBD bio-availability. This is because the CBD is only affected by the saliva in the mouth.
Inhaling/vaping CBD has by far the highest CBD bio-availability. The WHO states:
“Aerosolized CBD has been reported to yield rapid peak plasma concentrations in 5–10 minutes and higher bioavailability than oral administration.”
Bio-availability of CBD administered through vaping can be as high as 60%.
Is your CBD good value for money?
So now you can see that the bio-availability of CBD varies considerably depending on the method of administration, let’s apply this to the price. For the purpose of this calculation, we took an average price of ingested, sublingual and vape CBD products on the market and compared this to the price of our own CBD Calm range.
As you can see, vaping CBD, especially CBD Calm, you are getting much better value for money based on the bio-availability compared to the other methods of administering CBD.
Why choose CBD isolate
Another factor to consider when buying CBD is how accurate the strength actually is. A 2017 study by the University of Pennsylvania found that out of the CBD products tested, well over half were mislabeled as to how much CBD they actually contained. Psychoactive THC was even found in 21% of samples at levels that could intoxicate children!
With such inconsistency in the CBD market, CBD isolate has emerged as the best way to standardise the dosage and ensure that no THC is present. CBD isolate is the purest form of CBD available with no odour, flavour or other compounds. With CBD isolate, you can be certain the potency is exactly what it says on the bottle. Our CBD Calm range is made from 99.9% pure CBD isolate.

In conclusion …
What may seem to be the cheapest CBD in the UK, may actually be poor value for money. Always do the comparison between bio-availability and price as we have done above before you buy to make sure you are actually getting the best deal on CBD.
