What is bioavailability?

Why You Should Be Looking at CBD Bioavailability Before Choosing Between CBD Vape, CBD Oils, and CBD Edibles!

It’s an exciting time for everyone interested in their health because of the different CBD products available around the world right now. More now than ever before, we’re seeing more extensive research into premium CBD products and CBD itself.

With the recent passing of the 2018 Farm Bill in the United States, we’re seeing a lot more hemp CBD products hitting the market. The 2018 Farm Bill made it legal at a federal level for growers across the United States to not only grow hemp but also manufacture products from hemp. This increase in CBD products has made it even more important for people to consider the different properties and aspects of the CBD products which they purchase.

One thing not many people consider when they’re choosing a CBD product is the bioavailability of the CBD product which they’re choosing and how it will affect them. What is bioavailability? Let’s take a look at what bioavailability is and how it relates to the CBD products which you choose.

What Are Some of the Different Ways You Can Take CBD?

Before we get into bioavailability and what it means, let’s look at a few of the different delivery methods you can choose from when it comes to CBD products.

One of the most common delivery methods for CBD is CBD oil. It’s easy to take and can be quickly and easily added to different foods and drinks.

Another method of taking CBD is through CBD vape oils or juices. Vaping CBD is a quick and convenient way to take CBD wherever you find yourself during the day. The popularity of vaping CBD is increasing at a rapid pace.

The other popular way to take CBD is via edibles or supplements. CBD gummies are a very popular choice. Ultimately, the delivery method you choose should be the one which best suits your desired results. This is where the bioavailability of the delivery method plays an important role.

What Is Bioavailability and Why Is It Important?

Bioavailability is the measurement of how quickly something is absorbed and how much of it is absorbed into the bloodstream. Basically, the better the bioavailability of the delivery method, the more CBD will ultimately enter your bloodstream, and the better the result will be.

Different CBD products have different bioavailability rates, which affects how much of the CBD enters your bloodstream and how much is lost in the process. The higher the bioavailability, the more CBD you’re getting, and that equals not only better value for money but also much better results.

What is the Bioavailability of CBD Vape Oil or Vape Juice?

When vaped, CBD vape oils or vape juices have a bioavailability of between 34% and 46%, but some studies have put this figure as high as 56%. Vaping CBD is considered to be the most effective method of taking CBD.

Why is the bioavailability of CBD vape oil so high? It’s because the CBD is absorbed via the tissue in the lungs and then travels directly into your bloodstream. Now, the CBD can travel rapidly throughout the body binding with the CB1 and CB2 receptors located in the endocannabinoid system.

What is the Bioavailability of CBD Oils and Tinctures?

When you take CBD oil orally or via tinctures dropped directly under the tongue, the bioavailability rate is between 13% and 19%. Dropped under the tongue, the CBD enters the bloodstream via the sublingual gland. You must hold the CBD in the correct place under the tongue for this method to be 100% effective; otherwise, the CBD enters the stomach.

What is the Bioavailability of CBD Edibles?


While taking CBD oil or CBD gummies orally is a popular choice for many people, it’s also the least effective method. Studies have shown that the bioavailability of CBD, when taken orally, is as low as 10% and some studies have shown that it could be even closer to 6%.

This is because when you take CBD orally, it must travel through your digestive system before it enters your bloodstream. This process is not only slow (sometimes up to 2 hours), the majority of the CBD is lost as it is filtered by the liver and the digestive tract.

While this method is slower, and not as effective, it stays in your system longer than vaping CBD or CBD tinctures places under the tongue.


Ultimately, whichever method you choose has to suit your desired results and also your condition. It’s important to speak to your doctor or healthcare professional before ceasing or altering any of your current medications.
