"Since CBD is a lipophilic molecule, meaning that it has a physical affinity to fat or oil, the oil form is the most powerful and bioavailable," Di Polo explains. "Tinctures are absorbed the same way, but they are not as powerful and also lack the terpenes present in the oil form, while edible treats require the digestive absorption, making it the least bioavailable." The benefit to chews or treats, however, is the ease of delivery — not to mention, clear dosing since each treat or chew typically has a consistent amount of CBD, much like gummies for us humans. "For example, a 750mg bottle will have a range of one drop per every two to five pounds, and that equation would change if the bottle has 1500mg," Di Polo adds.
