Bioavailability is a term used to measure how much of a compound can be effectively used and absorbed by the body.

Studies have found that pure CBD isolate ingested on an empty stomach can have a bioavailability of just 6-10%. Meaning that significant amounts of CBD are degraded and excreted from the body. This is quite normal for fat-soluble compounds.

However, consuming CBD products with a source of fat can significantly boost bioavailability and the benefits of CBD by up to 8x in some cases. If your CBD edible product does not contain a source of fat, you could simply consume the edible within 30 minutes of eating a meal that does.
