Full Spectrum hemp extractions retain ALL of the various compounds of the whole plant, including THC.  It means everything in the plant remains in the formulation. There may be many cannabinoids, terpenes, fatty acids, acid precursors, flavonoids, vitamins and minerals. Our Comapnion's Best Day and the CBDA in our Mussel Complete are both full spectrum. Lab test results, known as the Certificate of Analysis (COA), may not indicate that some of these compounds are present, but this is common. Most labs don’t test for all things present, just the most important or most studied compounds like the core cannabinoids, and the absence of heavy metals and pesticides. Broad Spectrum means some of the of hemp compounds have been removed during the extraction process. The most commonly removed compound is THC. CBD Isolates contain CBD only and none of the other hemp compounds. These tend to be highly potent. There are some advantages to these if the specific need is to get the benefits of CBD only. There is no THC in CBD Isolates.
