Yes, Full Spectrum CBD is different from Broad-Spectrum CBD. It is basically about which compounds they contain. Broad Spectrum CBD is actually another name for CBD distillate. It is that CBD extract that retains all of its original cannabinoids, oils, vitamins, terpenes, and flavonoids. However, it goes through a special process, known as the winterisation process, to remove all THC.
Full-spectrum CBD on the other hand contains many naturally occurring cannabis plant compounds, such as other terpenes and other cannabinoids besides CBD. It also includes up to 0.2% THC.
Broad Spectrum CBD or CBD distillate is therefore convenient for those users who want to reap all the full-spectrum benefits, without ingesting any THC.
