What Does ‘bioavailability’ Mean?

Bioavailability is a pharmacological term that is used to describe the efficacy of absorption of a drug or substance into the body’s systemic circulation. Essentially, bioavailability is how much of a drug actually enters the bloodstream and flows to capillaries throughout the body following the process of digestion and metabolism. Bioavailability is considered to be at 100% when a drug or substance is administered intravenously.

Figuring out a medication’s bioavailability helps to determine the proper dosages of a medication to prescribe so that the right amount is administered to perform the intended function of the medicine.

For CBD, increased bioavailability means that the body is able to absorb more of the CBD and lose less during the process of digestion (if the CBD is taken orally through tinctures, capsules, and edibles).
