AerosourceH Nano CBD is an emulsion of purified water, long chain triglycerides, emulsifiers, and CBD.  While an emulsion simply refers to a mixture of oil and water, our Nano CBD is made using our proprietary process that uses sound waves to break the particle size of the CBD oil below 100 nanometers for faster absorption and increased bioavailability (learn more about Nano CBD and its advantages here: AerosourceH Nano CBD ).  This type of product is known as a nanoemulsion, and is used “in diverse areas such as drug delivery, food, cosmetics, pharmaceuticals, and material synthesis” [1].

We produce our Nano CBD in 2.5% (25 mg/mL) and 5% (50 mg/mL) concentrations, with a particle size of less than 100 nanometers.  These concentrations, coupled with the higher bioavailability of the small particle size, are appropriate for many CBD users.  However, some people do prefer an even more potent option to allow a higher amount of CBD per usage, to be able to use less of their chosen CBD product at once, or to get the most cost-effective form of CBD by having the highest concentration per drop.

Our Micro CBD is a 10% emulsion in purified water, produced using the same technology as our Nano CBD.  Because of the higher concentration of CBD in the formula, the finished particle size is somewhat larger than that of our Nano CBD, but is below 200 nanometers.  While there may be some companies marketing products with this particle size as “nano,” we feel it is important to distinguish between our Micro and Nano CBD products so our customers know what they are actually getting.

While “Li et al⁶² concluded from their data that the size of 100 nm might be the most suitable size for oral delivery of nanoparticles” [2], it has also been shown in a 2016 study by Banerjee et al. that absorption of nanoparticles “was inversely related to their size, with uptake of 50 nm > 200 nm > 500 nm > 1000 nm” [3].   This means that as the particle size gets smaller, the bioavailability increases.  Micro CBD therefore has a bioavailability advantage over oil-based or other non-emulsified forms of CBD.
