recent studies suggest that mineral deficiencies and imbalances are at the base of an entire class of auto-immune and behavioral diseases. You should look at Montmorillonite as a possible source of complete, viable multi-minerals. The products are safe, clean and the minerals are bioavailable...even better than many food-based minerals. They are released in a buffered form because they cling to the negative ionic silicate delivery system, which sweeps your system clean of heavy metals and pathogens. Most people report stunning results with calcium montmorillonite. See http://www.terramin.com
