There are distinct differences between the popularly known Isolate CBD, Broad Spectrum CBD, & full-spectrum CBD based products.
Isolate means that the CBD molecule has been isolated by itself, resulting in a fine white powder that can be infused into oil, creams, food, and more.
Broad spectrum CBD includes the CBD molecule, as well as small amounts of other molecules like CBN, CBG.  All THC has been removed.  Broad spectrum allows more phytocannabinoids to enter the body, providing more amplified effects compared to a plain Isolate.
Full-spectrum CBD contains the whole plant with nothing removed.  Full-spectrum products have been found to be the most beneficial long-term.
When you compare an Isolate product to a full-spectrum, it has been shown that Isolates show a bell-curve effect when it comes to tolerance. This means you must keep increasing your dose of an Isolated product to get the same results.  Eventually, it provides little to no effect. A full spectrum CBD product will not adhere to your tolerance; therefore making it a more beneficial long term product.
