mineral salts - Inorganic salts that need to be ingested or absorbed by living organisms for healthy growth and maintenance. They comprise the salts of the trace elements in animals and the micronutrients of plants.
"Our bodies need many metals but it is extremely important to realize two things about such needs. One is, that out of the many their total is only 1 1/2% of our bodies. The other is that not even a millionth of a milligram of metal enters the body in its free state. They can be present only as metal salts, or oxides. Iron, calcium, magnesium, sodium and many other metal salts are necessary, but only in infinitesimal amounts. To indicate the small amounts of metals the body will accept we cite such examples as manganese, which is present in only seven hundredths of one per cent, copper one thousandth, nickel two ten thousandths, and gallium three one hundred thousandths of one per cent. Iron, calcium, iodine, sodium and other metal salts are necessary also, but in extremely small fractions." [Atomic Suicide, page 33]
