Bioavailability refers to the amount of a compound that actually reaches the bloodstream. When we take CBD or CBDa, a percentage of it is lost through our digestive system, our enzymes, and various blocking mechanisms such as the skin. Research studies show that CBDa can actually enhance the potency of CBD. This means that users can consume smaller quantities while still experiencing the same level of effectiveness.Now that you know about the differences that exist between CBD and CBDa, you may wonder which one is better. The truth is that both of them provide good potential health benefits, making them both useful cannabinoids. Ideally, you should strive to take them both to enjoy the numerous health benefits they provide in tandem.
