Full Spectrum products have been made with an extract &/or concentrate that contains .03% THC or less by volume. *LOQ is a labs testing ability to test for low THC levels. This does not mean there is 100% no THC. While CBD isolate is the isolated cannabidiol in its purest form, full spectrum CBD contains other beneficial cannabinoids. This gives the Entourage Effect which results when the many components within the hemp plant interact with the human body to produce a stronger influence than any one of those components alone. Because of the benefits of the whole plant, full spectrum oils and products are typically used to treat more severe illnesses. Both CBD isolates and full spectrum CBD have their benefits. It simply depends on your preference and what you would like the product to accomplish.
