CBD and full spectrum CBD are both types of cannabidiol, a naturally occurring compound found in the hemp plant. However, there is a key difference between the two: full spectrum CBD contains all of the other compounds found in the hemp plant, including terpenes and other cannabinoids, while CBD isolate is a pure form of CBD that does not contain any other compounds.
Full spectrum CBD is thought to have some additional benefits over CBD isolate due to the entourage effect. The entourage effect is the idea that the different compounds in the hemp plant work together to create a more powerful effect than any one compound could on its own.
There is some research to support the entourage effect, but more research is needed. If you are interested in trying CBD, it is important to do your research and talk to your doctor first.
