Full-Spectrum, Broad-Spectrum, and CBD Isolate

CBD products are generally sold in one of three forms: full-spectrum, broad-spectrum, or isolate. Each differs in how much of the hemp plant’s original compound profile it retains.

Full-Spectrum CBD

Full-spectrum CBD contains all the phytochemicals naturally found in the hemp plant, including CBD, THC, terpenes, and a range of other cannabinoids such as CBG and CBN. THC is present in traceable quantities, up to the federal limit of 0.3%. Because it retains the plant’s full compound profile, full-spectrum CBD is often described as the closest product to a “whole plant” hemp extract that still stays within the federal definition of hemp.

Broad-Spectrum CBD

Broad-spectrum CBD does not contain traceable amounts of THC — it is almost completely removed after the initial extraction process, typically brought below 0.2% or to non-detectable levels (under 0.01%). It still contains many of the other cannabinoids and compounds found in the plant, including terpenes, flavonoids, and minor cannabinoids.

CBD Isolate

CBD isolate contains only CBD, with no other cannabinoids, terpenes, flavonoids, or plant compounds. It is the most refined form on the spectrum, usually 99%+ pure cannabidiol, and can contain 0.0% THC.

Why the Terms Vary

Industry sources note that “full-spectrum,” “broad-spectrum,” and “isolate” are not subject to uniform regulation, so their exact meaning can vary between manufacturers. The active CBD compound itself is the same regardless of whether it is sourced from hemp or marijuana, though the source plant can affect the terpenoid and cannabinoid profile of a full-spectrum extract.

Summary

The three spectrum types differ primarily in how much of the plant’s original chemistry — THC in particular — they retain after processing. Full-spectrum keeps everything within the legal THC limit, broad-spectrum removes THC while keeping other compounds, and isolate removes everything but CBD itself.
