The actual process of making CBD isolate commonly starts with a CO2 extraction which leads to the extraction of resins and oils from hemp. The winterization process that leads to the separation of lipids follows and removal of extraneous plant matter is eventually done. What remains after this is pure CBD isolate. Our highest concentration CBD product is available. CBD Isolate Canada contains no measurable amounts of THC, and it was the perfect option for those seeking high levels of CBD plus added B12 and Vitamin C with each tablet.
