This specially formulated tincture is to be applied under the tongue and held for 60 seconds. This is the quickest way to allow CBD to be absorbed. Because CBD and other cannabinoids are fat soluble, they are most effective when taken with saturated fats, such as MCT and Olive oils (EVOO). Please choose whether you would like MCT or EVOO as your base.There are two formulations of CBD tincture. One is supspended in MCT the other in Olive Oil. MCT is a flavorless medium chain diglyceride that comes from coconut oil. The olive oil has a mild flavor that some enjoy. It's really just a personal preference for most.
