Broad spectrum

Broad spectrum is a commercial label for a hemp extract that keeps many cannabinoids and terpenes but is processed to 0.0% THC.

The term sits between full spectrum, which retains the plant's THC, and isolate, which strips everything but a single cannabinoid. A broad-spectrum extract is generally made by taking a full-plant extract and removing THC through additional processing, or by blending isolated cannabinoids and terpenes back together. No federal regulation defines the phrase, so what it means in practice varies from one manufacturer to another.

Because the label is not standardized, the certificate of analysis is the only reliable way to confirm what an extract contains; a reader should look for the THC line reading 0.0% THC and for the cannabinoids actually measured. The idea that keeping multiple compounds together improves results is called the entourage effect, and it remains a hypothesis with limited clinical evidence. The same labeling logic applies to hemp products sold for pets.
