2:1 electrolytes are those having a divalent cation, such as Ca, Mg, Sr, Zn in the inorganic state, such as in
the hydroxides, chlorides etc. of these materials.
Dr. Price concluded that these forms are not absorbed by the body. The mayo clinic work and Riddick's work on Zeta Potential confirms this.
The natural forms of these minerals are the best, such as kale, beans, whole vegetables etc., but not aqueous solutions of these 2:1 electrolytes. Such solutions instantly destroy the zeta potential and cause coagulation.
