Full-spectrum means that the product contains the full spectrum of compounds (cannabinoids, terpenes, flavonoids, etc.) found in the hemp plant, including the cannabinoid, THC. Isolate CBD products are made from pure CBD isolate that has been singly separated from the hemp distillate extract. These products contain nothing else from the hemp plant except for CBD – no terpenes, no other beneficial cannabinoids. Broad spectrum products are the same as full spectrum except  that all traces of THC have been removed.
