Since we addressed in our last blog post how to use CBD isolate to make sublingual oil, we're taking the opportunity to break down the benefits of taking CBD sublingually. When talking about methods of consumption a good place to start is addressing the product's bioavailability which refers to the portion of a drug or other substance that enters the body's circulation in order to have an active effect. When using CBD or any products for that matter, you are looking for maximum bioavailability. So how can we maximize CBD's bioavailability? This is where sublingual use comes into play.
Take a look at the diagram below, this shows what happens to a substance when taken orally.
The substance, or CBD in this case, has very little bioavailability because it cannot be absorbed properly without having been mostly metabolized in the gut. This is called the first pass effect. First pass metabolism is the main reason for the low oral bioavailability of CBD. First pass metabolism is caused by the actions of enzymes of the gastrointestinal lumen, gut wall enzymes, bacterial enzymes, and hepatic enzymes-before CBD reaches the circulatory system.
In comparison, below is a diagram showing the absorption of CBD taken sublingually.
When you consume CBD sublingually, the oil is held under the tongue (the longer the better) as opposed to swallowing which causes the cannabinoids to be absorbed by the mucous membrane, allowing the CBD to pass into the bloodstream directly. Thus increasing bioavailability, allowing the user to experience relief sooner, and drastically lower the amount of CBD oil you need to consume in order to feel the effects.
