Solubility is crucial for getting CBD into the body efficiently. Most CBD has low bioavailability and therefore, very little CBD actually reaches the bloodstream for transport to its sites of action. Plus most CBD that is taken orally does not enter the body but is wasted and CBD degrades when stored which means not only a loss of potency in what you are actually taking but also a potential for ingestion of toxic or undesirable degradation byproducts.
