In CBD isolate products, CBD is the only Phyto cannabinoid present in the product. Meanwhile, in PCR Hemp Oil, you get the “full spectrum” of the Phyto cannabinoids (excluding THC). This is key. Research has found that in PCR Hemp Oil, the Phyto cannabinoids act together synergistically to bring you the maximum benefit. This is called the “entourage effect.” CBD is actually the dominant Phyto cannabinoid in full spectrum hemp oil. CBD Isolate products with CBD as the only Phyto cannabinoid does not benefit from the “entourage effect”.
