CBD capsules come in a wide variety of types, formulas, and potencies. CBD capsules often contain CBD oil formulas similar to those found in dropper bottles, however, a number of CBD capsules contain only purified CBD which has been encapsulated in a nanoemulsion and powdered. Nanoencapsulated formulas have a higher bioavailability, therefore lower doses may be required. 

CBD capsules deliver the active ingredients at the point of stomach or intestine. CBD capsules are also often used by those who dislike the flavor of CBD oil tinctures.
