Taking mineral supplements requires knowledge and caution, since once minerals enter the body, they compete with one another for absorption. For example, too much zinc can deplete the body of copper, while excessive calcium intake can affect magnesium absorption. Supplemental minerals should always be taken in balanced amounts and under an expert's guidance.
Nutritionally, minerals belong to two groups: bulk minerals and trace minerals. Bulk minerals include calcium, magnesium, sodium, potassium, and phosphorus. These are needed in larger amounts than trace minerals. Although only minute quantities of trace minerals are needed, they are nevertheless vital for good health. Trace minerals include boron, chromium, copper, germanium, iodine, iron, manganese, molybdenum selenium, silicon, sulfur, vanadium and zinc.
Reasons For Use
A good multi-mineral product may provide actual benefit or at least provide insurance value against unknown deficiencies. By consuming the average unsupplemented diet, there is a high probability of an individual not getting enough of one or more nutrients, not knowing which ones they might be. A good multiple supplement is inexpensive insurance against this likely event.
Directions
Once a mineral is absorbed, it must be carried by the blood to the cells and then transported across the cell membranes in a form that can be utilized by the cells. Because minerals compete with one another for absorption, supplemental minerals should always be taken in balanced amounts. Otherwise, they will not be effective and may even be harmful. The absorption of minerals can also be affected by the use of fiber supplements. Fiber decreases the body's absorption of minerals. Therefore, supplemental fiber and minerals should be taken at different times.
Side-Effects
Because minerals are stored primarily in the body's bone and muscle tissue, it is possible to develop mineral toxicity if extremely large quantities are consumed. Such situations are rare, however, because toxic levels of minerals generally accumulate only if massive amounts are ingested for a prolonged period of time.

GLOSSARY
Boron
A mineral that may play a role in maintaining strong bones, affecting calcium and magnesium metabolism and proper membrane function.
Calcium
The body's most abundant mineral. Its primary function is to help build and maintain bones and teeth. The body also needs calcium to carry nerve signals, keep the heart functioning, contract muscles, clot blood and maintain healthy skin. Calcium helps control blood acid-alkaline balance, plays a role in cell division, muscle growth and iron utilization, activates certain enzymes, and helps transport nutrients through cell membranes. Calcium also forms a cellular cement called ground substance that helps hold cells and tissues together.
Chromium
Chromium is a mineral that becomes a part of the glucose tolerance factor (GTF). Chromium aids in insulin utilization and blood sugar control. By controlling blood sugar, chromium helps prevent the damage caused by glucose, which is called glycation. Chromium helps maintain normal cholesterol levels and improves high-density lipoprotein levels. Chromium is also important in building muscle and reducing obesity.
Copper
An essential mineral that is a component of several important enzymes in the body and is essential to good health. Copper is found in all body tissues. Copper deficiency leads to a variety of abnormalities, including anemia, skeletal defects, degeneration of the nervous system, reproductive failure, pronounced cardiovascular lesions, elevated blood cholesterol, impaired immunity and defects in the pigmentation and structure of hair. Copper is involved in iron incorporation into hemoglobin. It is also involved with vitamin C in the formation of collagen and the proper functioning in central nervous system. More than a dozen enzymes have been found to contain copper. The best studied are superoxide dismutase (SOD), cytochrome C oxidase, catalase, dopamine hydroxylase, uricase, tryptophan dioxygenase, lecithinase and other monoamine and diamine oxidases.
Germanium
A trace mineral.
Iodine
A essential mineral that is an integral part of the thyroid hormones, thyroxin and triiodothyronine which have important metabolic roles and govern basal metabolism. The best known iodine deficiency symptom is goiter. Other iodine deficiency problems are reduced vitality, hypothyroidism, inability to think clearly, low resistance to infection, loss of control of the muscles of the mouth resulting in mouth contortion and drooling, defective teeth, tendency to obesity and cretinism which is a congenital abnormal condition marked by physical stunting and mental deficiency.
Iron
An essential mineral. Prevents anemia: as a constituent of hemoglobin, transports oxygen throughout the body. Virtually all of the oxygen used by cells in the life process are brought to the cells by the hemoglobin of red blood cells. Iron is a small but most vital, component of the hemoglobin in 20,000 billion red blood cells, of which 115 million are formed every minute. Heme iron (from meat) is absorbed 10 times more readily than the ferrous or ferric form.
Magnesium
An essential mineral. The chief function of magnesium is to activate certain enzymes, especially those related to carbohydrate metabolism. Another role is to maintain the electrical potential across nerve and muscle membranes. It is essential for proper heartbeat and nerve transmission. Magnesium controls many cellular functions. It is involved in protein formation, DNA production and function and in the storage and release of energy in ATP. Magnesium is closely related to calcium and phosphorus in body function. The average adult body contains approximately one ounce of magnesium. It is the fifth mineral in abundance within the body--behind calcium, phosphorus, potassium and sodium. Although about 70 percent of the body's magnesium is contained in the teeth and bones, its most important functions are carried out by the remainder which is present in the cells of the soft tissues and in the fluid surrounding those cells.
Manganese
An essential mineral found in trace amounts in tissues of the body. Adults normally contain an average of 10 to 20mg of manganese in their bodies, most of which is contained in bone, the liver and the kidneys. Manganese is essential to several critical enzymes necessary for energy production, bone and blood formation, nerve function and protein metabolism. It is involved in the metabolism of fats and glucose, the production of cholesterol and it allows the body to use thiamine and Vitamin E. It is also involved in the building and degrading of proteins and nucleic acid, biogenic amine metabolism, which involves the transmitting of nerve impulses.
Mineral (Minerals)
Plays a vital role in regulating many body functions. They act as catalysts in nerve response, muscle contraction and the metabolism of nutrients in foods. They regulate electrolyte balance and hormonal production, and they strengthen skeletal structures.
Molybdenum
An essential trace element. It helps regulate iron stores in the body and is a key component of at least three enzymes: xanthine oxidase, aldehyde oxidase and sulfite oxidase. These enzymes are involved with carbohydrate metabolism, fat oxidation and urine metabolism. The average adult has about 9mg of molybdenum concentrated mostly in the liver, kidney, adrenal glands, bones and skin. Molybdenum deficiencies are associated with esophageal cancer, sexual impotency and tooth decay.
Phosphorus
The second most abundant mineral in the body, found in every living cell. It is involved in the proper functioning of both muscles and nerves. It is needed for metabolic processes of all cells, to activate many other nutrients, and to form energy-storage and energy-releasing compounds. The phosphorus content of the body is approximately 1% of total body weight. Phosphorus combines with fats to form phospholipids. Combined with calcium, it gives strength and rigidity to the bones and teeth.
Potassium
A mineral that serves as an electrolyte and is involved in the balance of fluid within the body. Our bodies contain more than twice as much potassium as sodium (typically 9oz versus 4oz). About 98% of total body potassium is inside our cells. Potassium is the principal cation (positive ion) of the fluid within cells and is important in controlling the activity of the heart, muscles, nervous system and just about every cell in the body. Potassium regulates the water balance and acid-base balance in the blood and tissues. Evidence is showing that potassium is also involved in bone calcification. Potassium is a cofactor in many reactions, especially those involving energy production and muscle building.
Selenium
An essential element involved primarily in enzymes that are antioxidants. Three selenium- containing enzymes are antioxidant peroxidases and a fourth selenium-containing enzyme is involved in thyroid hormone production. The prostate contains a selenium-containing protein and semen contains relatively large amounts of selenium. Clinical studies show that selenium is important in lowering the risk of several types of cancers. In combination with Vitamin E, selenium aids the production of antibodies and helps maintain a healthy heart. It also aids in the function of the pancreas, provides elasticity to tissues and helps cells defend themselves against damage from oxidation.
Silicon
A non-essential mineral. Tissues such as arteries, tendons, skin, connective tissue, cornea and sclera (white of the eye) contain relatively large amounts of silicon. Collagen, the protein glue that holds us together, contains silicon in silanolate form. While vitamin C functions only as a catalyst in the formation of collagen, silicon is actually a structural part of collagen. Silicon containing substances are found in all cartilage and in the material binding cells together. Silicon may be needed for proper bone structure and growth.
Sodium
An essential mineral that our bodies regulate and conserve. Excess sodium retention increases the fluid volume (edema) and low sodium leads to less fluid and relative dehydration. The adult body averages a total content of over 100 grams of sodium, of which a surprising one-third is in bone. A small amount of sodium does get into cell interiors, but this represents only about ten percent of the body content. The remaining 57 percent or so of the body sodium content is in the fluid immediately surrounding the cells, where it is the major cation (positive ion). The role of sodium in the extracellular fluid is maintaining osmotic equilibrium (the proper difference in ions dissolved in the fluids inside and outside the cell) and extracellular fluid volume. Sodium is also involved in nerve impulse transmission, muscle tone and nutrient transport. All of these functions are interrelated with potassium.
Vanadium
Non-essential mineral. It is believed that Vanadium is probably essential to growth and involved in fat metabolism. A vanadium deficiency can increase blood cholesterol and triglyceride levels.
Zinc
An essential trace mineral. The functions of zinc are enzymatic. There are over 70 metalloenzymes known to require zinc for their functions. The main biochemicals in which zinc has been found to be necessary include: enzymes and enzymatic function, protein synthesis and carbohydrate metabolism. Zinc is a constituent of insulin and male reproductive fluid. Zinc is necessary for the proper metabolism of alcohol, to get rid of the lactic acid that builds up in working muscles and to transfer it to the lungs. Zinc is involved in the health of the immune system, assists vitamin A utilization and is involved in the formation of bone and teeth.
