Although new in the CBD scene, nano-pharmaceuticals have been around for a while now and their existence may point to the very reason proponents of nano CBD have extolled its virtues. The main selling point? Higher bioavailability. Bioavailability pertains to the rate the body absorbs a specific substance. With standard CBD oil, absorption is at 10 percent or less, with liposomal microemulsion CBDs, it bumps up to 20 percent, but with nano-sized microemulsions, it reaches up to 50 percent. A pretty big difference, and if you’re looking to get the most out of your CBD and get the best value for your money, bioavailability is a huge factor in choosing a product.
