CBD Isolate is a Single-Molecule CBD product. It is derived and then extensively refined from Industrial Hemp and has been on the market for several years. Full Spectrum CBD is extracted from the whole plant, excluding the stems and stalks, and are never synthetic.
In order to properly use Isolate products you need a precise, high dose in a rather narrow therapeutic window. Full Spectrum products have a greater effect with lower doses and can be done in a much larger window.
This is because Full Spectrum CBD products contain critical secondary cannabinoids and other medical compounds that are left in from high-resin strains. These compounds interact with the CBD to enhance the therapeutic benefits. Scientists call this the “entourage effect”.
