There are three categories when it comes to hemp-derived CBD based products. 1) full-spectrum 2) broad-spectrum3) isolates. Full Spectrum indicates the whole plant was used for extraction and includes the following compounds:  cannabinoids, plant terpenes, flavonoids, and fatty acids. All of the aforementioned ingredients work together in what is known as the entourage effect to amplify the benefits. Broad Spectrum indicates a full-spectrum extract was further processed to remove trace amounts of THC.  Broad-spectrum CBD is essentially full-spectrum without any THC. It offers all of the entourage effect associated with full-spectrum without THC in it. Isolate indicates all compounds associated with the hemp plants such as other cannabinoids, plant terpenes, flavonoids, and fatty acids were stripped except CBD. It is a pure, crystalline powder that contains 99% pure CBD. This is the purest CBD product available in the market today and contains 0.0% THC.
