Did you know that only around 10% of CBD oil you swallow is absorbed? Even taking it sublingually (under the tongue) results in only 35% absorption rates at most (probably lower).
The fact is, everytime we consume CBD oil, we are not getting even 50% of the cannabinoids present. It’s a waste – and not a cheap one considering the high prices of good CBD products in the UK.
Which is why water-soluble CBD products may the more effective and economical option thanks to their increased bioavailability.
What is bioavailability?
When it comes to CBD products, there are many different types each with differing absorption rates. The absorption rate of a product is known dependent as its bioavailability (literally, its availability to the body).
CBD oil is the most well-known CBD product. This can be taken orally (swallowed), sublingually (absorbed under the tongue), or topically (absorbed through the skin). CBD can also be inhaled via the lungs by vaporisation or smoking, or rectally with the use of CBD suppositories.
Each of these methods are pretty wasteful, however. The most efficient method is inhalation via vaporisation, and it only has an absorption rate of just over 50%. This is a big increase compared to the roughly 10% absorption rates of taking CBD oil orally.
Absorption rates of CBD products in the UK
Absorption rates vary between CBD products varies a lot. As well as the method of consumption, there may be other factors that determine absorption rates, such as gut health, food timing and the quality of the CBD product you’re using.
CBD oil: 4-35% – Take CBD oil sublingually while eating a fatty meal for optimal bioavailability.
CBD edibles: 4-20% – Again, for maximum absorption, eat alongside a fatty meal.
CBD vapes: >56%
CBD flower: >56%
CBD topicals: >45%
CBD suppositories: 8-50%
What is water soluble CBD?
Cannabinoids are naturally fat-soluble, which means they mix well with oils, but not water. Therefore, water soluble CBD is a pretty recent innovation.
While there are a variety of methods used, the basic premise is that the CBD molecules are broken apart and made small enough that they can effectively blend with water molecules.
The idea is that smaller CBD compounds, or nanoparticles, will absorb more efficiently into the bloodstream this way.
Water soluble CBD is usually made using combining CBD with a micro-emulsifier at high pressure or with microscopic structures that can be used to encapsulate the CBD molecules.
Is water soluble CBD better CBD oil?
There is a study that suggests that CBD encapsulated in nano-lipospheres are absorbed up to 600% more than oil-based CBD (in rats, at least). While this shows the efficacy of just one type of water-soluble CBD out of many, it does make sense that small CBD molecules are more readily absorbed into the bloodstream.
Therefore, a high-quality water-soluble CBD product is going to be better value for money than your typical oil-based CBD product (probably around 80% of the current market).
How to use water-soluble CBD
A great thing about water soluble CBD is its versatility. Not only can you mix it with water and other drinks, it can just as easily be sprayed or added to food.
You can also use it sublingually by putting a few drops under your tongue. This method may well be the most efficient from a bioavailability standpoint as it avoids the gut altogether.
