It’s critical to understand what bioavailability is and what it means
to you if you use CBD.

BIOAVAILABILITY is the proportion of a drug or other substance which enters the circulation when introduced into the body and so is able to have an active effect.

As you can see from the chart, bioavailability is a critical element in supporting both efficacy and cost to the user. The chart shows all the different delivery methods in which CBD can enter your body.

In the most relevant comparison, we look at the most popular delivery system which is what the more than 600 CBD oils use to deliver CBD. There are a number of really good CBD oils available and the information is out there to help people make the right decision for them. But things get very confusing, very fast.

Some companies label their product with what the total liquid volume is. For example they might offer you 2 ounces of CBD Oil without telling you how much CBD is in that 2 ounces. If they don’t tell you right away how much actual CBD they are selling …. STOP … find another product right away.


The market in this explosive new CBD industries loaded with bad products. It will take a few years to clean these bad companies out, but it will happen. In the meantime, responsible companies will continue to help educate and inform the consumers.

On the other hand, when a new delivery system enters the marketplace and they are offering published proof of superior bioavailability, the industry will ultimately gravitate to the superior delivery system. That seems to be the case with the introduction of CBD products that will use purified water instead of a carrier oil.

This is where things start to get very interesting. Any product that uses a carrier oil will need to be processed through the digestive tract when it is swallowed. Any products that use purified water will not be processed through the digestive tract. With purified water the product when sprayed directly into the mouth will enter the bloodstream very quickly through the soft tissues in the cheeks called buccal mucosa.

Cost is always an important consideration. When we compare an oil-based product to a product that uses purified water as their delivery system when both products are of the same efficacy, the results are astounding. The published proof in the PDR (physicians desk reference) shows that a CBD user would need to buy two bottles of oil that contained 200 mg of CBD to get the same benefit of one tube of CBD that uses purified water to deliver the CBD.

This important development in the CBD marketplace clearly will be gaining a lot of attention as the awareness of this type of delivery system gains traction.
