This article provides some basic definitions of isolate, full and broad spectrum
Full-Spectrum CBD: Full-spectrum CBD products contain a variety of cannabinoids, including trace amounts of THC (less than 0.3%). Also known as full-spectrum CBD or hemp oil distillate, full-spectrum goods typically contain 70% to 90% CBD with the balance including other cannabinoids (such as THC, CBG, CBC, and CBN), terpenes, and other plant oils.
Broad-Spectrum CBD: Broad-spectrum CBD products also contain a variety of cannabinoids but, unlike full-spectrum goods, do not include any THC. These goods are created via a similar method to full-spectrum products, but the THC is removed in the distillation process. As a result, typically 80-90% of the distillate is comprised of CBD.
CBD Isolate: Unlike the other two forms of CBD, CBD isolate products only contain CBD and are completely free of additional cannabinoids. Isolate typically contains 95-100% CBD and is free of flavor and odor.
