Calcium
Calcium the mineral needed in the largest quantities in animals can be taken as an example.
Calcium does not occur naturally as the metal calcium, but occurs in nature as various salts.
The main naturally occuring calcium salts are calcium carbonate, the most common form, (chalk, limestone, marble and
dolomite), calcium sulphate (gypsum), calcium fluoride (fluorspar), and calcium phosphate (complexed as apatite and organic bone meal).
Calcium carbonate is the cheapest but is often poorly obsorbed when compared with calcium phosphate (hydroxyapatite complex).
Calcium phosphate is well obsorbed and utilised, perhaps because its animal source gives it the inherent balance most
suited to animal absorption.
Calcium fluoride, on the other hand, is toxic in large quantities and therefore is not suitable as a source of calcium.
However, it has important therapeutic value when used as a trace element.
This natural form of fluoride is useful not only in arthritis and splints, helping break up exoctoses and indurated glands,
but also strengthens prolapsed muscles and veins, helping to re-establised elasticity.
Calcium sulphate, also is not well tolerated or obsorbed as a bulk source of calcium, but it has therapeutic value in small
dispersed doses.
It is particularly helpful in suppurative conditions such as chronic, thick, yellow and lumpy mucus discharges, recurrent
abscesses and poor healing after injury.
Several laboratory prepared salts and calcium are also in wide use and some of these show good obsorption compared with calcium carbonate.
The most useful of these are the chelated calciums, combined to amino acids and other organic nutrients such as
calcium orotate and calcium gluconate. However, these do not provide the phosphate balance found in the organic calcium phosphate complex.
Sodium
Another interesting example is
sodium and three of its salts. Generally, there are no problems with the absorption of any sodium salts.
All
sodium salts are involved in fluid balance. Sodium chloride, common salt, is essential to maintain normal osmotic fluid pressure
both within and outside cells, and also facilitates normal nerve conduction.
Sodium sulphate (Glaubers salts), when given in small doses (5-10) grams per day, has a diurectic action in horses, shifting excess fluid
from the tissues and bloodstream, stimulating both kidney action and bile production.
Excessive doses, however, only act as a bowel purgative, as do excessive doses of Epsoms salts.
Sodium phosphate has different properties again. It is useful in similar small doses, but more than other sodium salts, it aids
the breakdown of excess tissue lactic acid and promotes water absorption. It is also effective in reducing gastric acidity.
