This 2018 study aimed to investigate the pharmacokinetics of CBD in healthy dogs using three different formulations: oral microencapsulated oil beads, oral CBD-infused oil, and CBD-infused transdermal cream.
The findings of this randomized controlled trial refute a popular industry belief that topical or microencapsulation product formulations can somehow result in the highest CBD absorption.
Instead, the study once again validates the high standards of a small minority of formulation scientists in the industry who prioritize scientific evidence, efficiency, and optimal health over new popular marketing trends like these unnecessary microencapsulated oral technologies.
As confirmed by other studies, the regular oral CBD-infused oil formulation demonstrated the most favorable pharmacokinetic profile, exhibiting higher maximal concentrations and systemic exposure compared to the other two formulations.
The participants took doses of 75mg or 150mg CBD every 12 hours for six weeks. The exposure was dose-proportional, and oral CBD-infused oil provided the most favorable pharmacokinetic profile.
The researchers originally hypothesized that the transdermal cream route of administration would be more effective in delivering CBD due to its avoidance of first-pass effect from the liver, which typically reduces the bioavailability of orally administered CBD in both and humans.
However, in this study, what has already been known by some in the industry was confirmed that the CBD-infused transdermal cream did not reach similar plasma concentrations as the other 2 oral formulations.
Contrary to popular belief in the industry that microencapsulated or topical versions of CBD absorb better than regular oral CBD oil, this study provides more scientific evidence that oral CBD-infused oil is actually superior in absorption.
This highlights the importance of conducting rigorous independent research and not relying solely on industry claims when making decisions about purchasing products.
These findings suggest that the oral CBD-infused oil formulation is the most superior option for the best absorption of CBD in dogs.
