What is the absorption rate?

To better understand the absorption rate of different CBD products, it's best to measure the absorption method. Sublingual oral absorption (under the tongue) is known to have the highest absorption rate, compared to digestive absorption (via capsules) or topical absorption (via topical). 

In terms of the actual absorption rate, we have to be honest in saying that such data is still being researched. Such studies have to be conducted by a scientific or research body, and via clinical trials. As CBD is still not fully approved by the FDA and most medical studies are still ongoing, there are no published scientific papers that can affirm the metrics.
