There really isn’t any standard when it comes to full spectrum or broad spectrum because of the varying opinions of what really are the active components of hemp or cannabis.  The difference between broad and full spectrum and isolate, at least when it comes to CBD products, is that in the extraction process (from plant material to oil), full spectrum oil contains all available cannabinoids, terpenes and flavinoids (including THC).  Many companies dilute the full spectrum oil so that the amount of THC is below 0.3 % and legally considered hemp. Broad spectrum oil is the same but the THC content is removed to be in undetectable amounts. CBD isolate is all other cannabinoids and other active compounds are removed and you’re left with just CBD.  This may sound like more bang for your buck for CBD consumers, but almost all experts believe that there is so much complexity to the hemp/cannabis plant that we are still unaware of, but that the other active components (especially the many cannabinoids and terpenes) that need to be present for the plant to really be effective.
