A CBD isolate contains only CBD. A full spectrum CBD will contain additional terpenes and cannabinoids, such as CBG and CBN, which have also shown benefits. We sell both full spectrum and isolate CBD products. THC levels are below legal limits at 0.3%. The illustration below represents The Full Spectrum Wheel (including several cannabinoids) where as CBD only would be considered an Isolate. Each type of CBD has it's own benefits, however there is much to be said about the "Entourage Effect"
