Hemp Derived CBD is available in a variety of forms. Depending on your preference and need, there are several delivery methods that are more or less bioavailable. Bioavailability is the degree and rate at which a substance, such as CBD oil, is absorbed into the bloodstream.
Under the tongue, there is a vein called the sublingual gland. When a substance is administered to the sublingual gland, it gets absorbed directly into the bloodstream, which is referred to as sublingual consumption. Common sublingual consumption methods include CBD tinctures, CBD lozenges and CBD sprays.
Because sublingual consumption is more direct, it impacts the body quicker than oral consumption and maintains higher availability, only being degraded from enzymes in the mouths saliva.
Because there are a few different factors that will impact the CBD bioavailability of sublingual consumption (most involving the quality of CBD), reported rates range from 12%-35%, which is still significantly higher than oral consumption.
