CBD oil is derived from hemp, so hemp and CBD oil are the same. Broad Spectrum CBD oil is the base ingredient of ReThink products. It is highly effective because it contains all of the essential oils, fatty acids, and aminos that would normally be stripped away in isolate products. In our opinion, isolate CBD can be compared to squeezing out all the Vitamin C from an orange. You can still drink the juice, but it’s not the same.
