CBD isolate is comprised of 99 percent or higher CBD.
Everything else including the THC and other cannabinoids, and plant materials like terpenes, oils, and chlorophyll has been removed. What’s left are naturally-derived CBD crystals that are odorless and flavorless.
If it’s CBD and CBD only that you’re after, CBD isolate is the best option available.
Because CBD is non-psychoactive, the isolate powder is a good option for those looking to avoid THC and its effects.
