Re-mineralization of our bodies without Fulvic has little benefit because colloidal minerals by themselves are not readily useable by cells. It is the Fulvic in conjunction with minerals that makes them effective.
Fulvic makes vitamins more absorbable by complexing them into organic, ionic forms that are easily transported into and through membranes and cell walls. Once the nutrients meld into the Fulvic complex, they become bioactive and bioavailable.
