Sublingual and Oral administration of CBD products are very similar since they both initially enter the body through the mouth. Sublingual administration has higher availability due to the fact that products are held under the tongue for a period of time where there is a high concentration of blood vessels. This allows a greater amount of the CBD to be absorbed directly into the blood stream. After being swallowed sublingual tinctures and orally taken CBD products are passed through body nearly identically. The digestive system destroys the greater portion of the products before they enter the bloodstream and become available to the body.
