When a product label says full spectrum CBD, it means the extracted formula containing the full range of beneficial chemical compounds naturally occurring in the hemp plant; it produces no psychoactive effects, as it contains trace amounts of less than 0.3 percent THC, falling below the legal limit. In broad spectrum CBD, the beneficial chemical compounds are maintained from the hemp plant, while removing any trace amounts of THC. CBD isolate takes it one step further, removing all other compounds from the formula, leaving behind pure, unadulterated CBD in an isolate form at more than 90 percent cannabidiol.
