a member of the smectite family is a 2:1 clay, meaning that it has 2 tetrahedral sheets sandwiching a central octahedral sheet.  The particles are plate-shaped and extremely small with an average diameter of approximately 1 micrometer.  Montmorillonite’s colloidal nature lends it well to the transport of nutrients and enhanced bioavailability of nutrients.

                  CLAY  MINERALS  FOR  MAN


    "Since 1950 I have advocated the use of the clay mineral Montmorillonite for the very reason that this clay mineral, Montmorillonite, contains all the essential mineral trace elements - in a balanced ratio as laid down by Nature.   Montmorillonite as mined and processed, is a natural mineral, containing no harmful elements of any kind.  It has no direct therapeutic effects, but acts as a normalizer of physiological activities in animal tissues.   In comparing the chemical analysis of the mineral with the chart of biological elements, we notice that the mineral contains all of the variable, and invariable elements of the animal tissues.   In comparing the chemical of the mineral with the analysis of blood and tissues, we again notice a similarity.  However, the mineral contains the elements in a slightly higher percentage.   According to these figures the mineral will furnish any one of the variable and invariable elements that might be lacking in the particular animal’s body tissues, or in the feeds furnished to it."

    Because of the many interactions and interdependencesamong minerals, it is believed that the availability of many minerals, even in minute quality, may be more effective than larger quantities of only two or three minerals.  We quote Dr. Walter Mertz, M.D., head of the United States Department of Agriculture's Nutrition Institute at Beltsville, Maryland.  "It is not enough to be concerned about the optimal intake range of any one nutrient by itself - what is optimal varies, depending on what other nutrients are interacting with it at that particular time.  A given intake of a specific nutrient can be ideal, deficient, or excessive, depending on what other substances are also present."

    "Take dietary Iron.  The requirement for human nutrition is very strongly dependent on the presence and concentration of several factors: Vitamin C, Copper, Nickel--and a special factor in meat, poultry, and fish--all enhance the availability of iron.  In other words they help you to absorb it.  But then there are other substances, such as the tannin in tea, which reduces the availability.  So, if you have an iron intake, and your intake and your diet is favorable in regard to the ‘enhancing’ factors, i.e., containing some Vitamin C, Copper and Nickel, or meat, poultry, or fish factor--the amount of Iron may be ample.  But if you have a diet that contains a lot of tannin and phosphate, but is low on ‘enhancers’, the same amount of Iron will be insufficient."

    "There are at least a hundred other interactions that have already been identified.   And I am sure there are more that we have not yet been able to spot."

    We provide you with a quantitative analysis of the essential elements and those suspected as essential, but not yet proven.  It is obvious that the relative quantities do not correspond with the FDA RDAs, but because of the similarity of the ratio of the elements in the deposit to that found in blood and tissue, it just might be that nature knows more than we humans.
