Colloidal mineral supplements are the liquid extracts of minerals
mainly derived from humic shale deposits or from
aluminosilicate-containing clays (however colloidal minerals may
also be derived from certains plants). Shale extracts predominantly
contain sulfates of iron and aluminum and traces of colloidal metal
hydroxides. The term colloidal mineral is derived from the presence
in these preparations of colloidal metal
hydroxides.
Additionally, colloidal minerals from humic shale
deposits contain zinc, nickel, manganese, magnesium, calcium,
chromium, boron, copper, lithium and silicon. They also contain
traces of several other elements including arsenic, vanadium,
strontium, selenium, iodine and praseodymium. Similar minerals may
be found in colloidal minerals derived from both clay and from plant
sources. It is believed that some forms fo colloidal minerals are
more easily absorbable than minerals in solid form (tablets and
capsules).
Toward the later part of the 20th century
colloidal mineral began to be marketed as a "nutritional
supplement." However, almost all claims that colloidal mineral was
an effective nutrient with numerous medical indications. To date no
scienfic study has substantiated that colloidal mineral supplements
offer any health benefits at all. In fact, the U.S. Food and Drug
Administration (FDA) state that all over-the-counter (OTC) products
containing colloidal minerals are not recognized as safe or
effective.
