How you take CBD can impact how much ends up in your system
Depending on how you take CBD (ingest, vaping, topical, etc), the amount of CBD that actually makes it into your blood stream will vary. For example, if you take a CBD capsule, only a small fraction of the CBD will end up making it to your bloodstream as it has a very low oral bioavailability. This 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.
For other administration methods—such as vaping, sublingual (dropping under the tongue), and topicals—the CBD will have an easier route into the bloodstream. This, in effect, allows for a greater proportion of CBD in these products to enter the body. Therefore, the same amount of CBD in capsule format may not have the same outcome as the identical CBD amount taken via other administration methods. Users should consider experimenting with different administration methods to find their optimal solution.
