Bioavailability: <5%
While transdermal patches offer higher absorption rates, the typical CBD cream, salve, balm, or muscle rub offers a low CBD bioavailability. Hovering around 5% makes it all the more important to find a CBD topical that contains a high amount of CBD (with lab tests to prove).
While topicals remain the lowest bioavailable CBD application, they also offer the most targeted application, and therefore, what little CBD penetrates will at least go directly into the area that needs it.
With little CBD entering the system and without the need to digest it first, a topical user can feel free to use it liberally and often throughout the day.
