Bioavailability of CBD referes to the amount of CBD that can be absorbed into your circulatory system within the body, and the rate at which this happens. This varies between CBD product types, with CBD oils having one of the highest rates of bioavailability.


You might have heard CBD experts talking about bioavailability, but what does it actually mean? And why is it a vital factor when picking CBD products?

Here, we break down everything you need to know about CBD bioavailability, from the most absorbent methods to simple tips that enhance your experience.

What is CBD Bioavailability?

You may already know there’s a host of ways to take CBD, from swallowing a daily CBD capsule to adding a CBD oil to your AM latte or other CBD drinks. However, what you may not know is each product has a different bioavailability rate, meaning some methods allow for easier absorption in the body.

It’s important to keep bioavailability in mind when choosing CBD. You might think increasing the milligrams equals increasing the strength – and whilst this is true, bioavailability also plays a key role. So, let’s look at the options.

CBD with the Highest Bioavailability Rate

Ingesting CBD via an CBD oil, CBD capsule or CBD gummy is the most effective way to take CBD, giving you the next highest bioavailability rate.

CBD oils are applied sublingually, which involves placing a few drops of CBD Oil under your tongue – where the large blood vessels are close to the surface – allowing it to cross the thin membrane and enter directly into your bloodstream. CBD capsules are simple, simply swallow 1-2 with water and let them get to work. And CBD gummies? Simply chew and go.

The fast absorption means CBD Oils enter the bloodstream just 15-30 minutes after ingestion. Try it with our CBD Oil Drops, which are infused with a clean, bright Juniper Lime flavouring that makes sublingual application all the more enjoyable.
