High CBD bioavailability CBD oil

A Brief and Simple Guide to CBD Bioavailability

CBD bioavailability refers to the amount of CBD that reaches the bloodstream. When we take CBD, whether we put oil under our tongues or digest a CBD gummy, some of it is lost on the way to the bloodstream.

CBD Under the Tongue

When taking a CBD oil sublingually (under the tongue), it is absorbed into the mucous membranes and then into the bloodstream within 15 minutes. This is a fairly quick CBD Absorption process with minimal obstacles (e.g. the digestive system) so the CBD bioavailability of CBD oil under the tongue is high.

Bioavailability: 10-30%

Digesting CBD

When swallowing and digesting CBD, whether it is through an oil, drink, capsule or edible, it can take around an hour to get into the bloodstream. This is because CBD must go through the digestive system, where a lot of the CBD is lost. CBD is then metabolised in the liver before getting into the bloodstream. Throughout this whole process, a lot of CBD is lost; less than 20% is absorbed into the bloodstream. CBD is not very bioavailable when digested.

Bioavailability: 5-20%

Inhaling CBD

When vaping or dabbing CBD, it is within the bloodstream as quick as it would be when taking CBD oil sublingually. CBD goes to your lungs and then through the membranes into the bloodstream, all within around 15 minutes. Inhaling CBD has proven to be the most bioavailable method. Its high CBD Absorption. 

Bioavailability: 10-60%

Applying CBD Topically

When applying CBD topically (on the skin), whether with creams, balms, serums or body oils, it is absorbed by the pores in your skin but does not in fact reach the bloodstream. In rare circumstances, maybe if you’ve put an extreme amount of CBD cream on your skin, some will reach the bloodstream.

Applying CBD topically is the least bioavailable method but that doesn’t mean it isn’t useful. CBD Absorption in Topical CBD products is great when wanting to target a particular area of the skin. The only exception is topically applying a transdermal CBD patch, which releases CBD oil through the skin and into the bloodstream. Buy CBD Patches Here.

How to Increase CBD Bioavailability

If you want high bioavailability, then you should go for CBD oils or vapes. Oils may be the better option as when vaping CBD, it only lasts in the body for around an hour.

When chewing on a CBD edible, try to keep it in your mouth for around a minute so that some of the released oil can go through the mucous membranes.

One way to increase CBD bioavailability is to take CBD alongside a meal, especially a high-fat meal. The CBD is metabolised easier.

We strongly recommend full spectrum CBD products as all cannabinoids and terpenes work in synergy together to produce the entourage effect, meaning the CBD will have a stronger effect. The terpenes also help increase bioavailability as they break down the CBD further.
