CBDPure oils are made with non-GMO hemp, grown in Washington and Colorado by local family farmers. Their hemp oil is minimally processed by following the highest organic standards at every step of our planting, growing, harvesting, and bottling processes. When you buy a CBDPure product from us, you are buying the purest CBD oil from natural sources, that is 100% free of any synthetic or artificial ingredients. No fillers, no preservatives, and nothing that isn't found in nature. They test every batch of oil that is processed to ensure that it meets the purity standards that they demand.
