Magnesium
If you scored two or more you may be lacking proper Magnesium balance in
your body. These vital minerals have many functions in the body, and are known
to effect long term health
Recent research at leading universities has shown what was suspected for
a long time - namely that many trace minerals are needed for optimal absorption
and retention of Magnesium in an absorbable form.
Suggested Products:
Bio Calcium contains the minerals magnesium, manganese, boron, zinc, and
copper which have been shown to increase the uptake of calcium by the bone.*

MAGNESIUM
IMPORTANCE:
Magnesium (Mg) is the fourth most abundant mineral in the body, with 60%
in the bone and 40% distributed equally between muscle and non-muscular soft
tissue.
Only 1% of magnesium is extracellular. Magnesium plays a key role in at least
300 fundamental enzymatic reactions,(Particularly those that require three B
vitamins (THIAMIN, RIBOFLAVIN and PYRIDOXINE), vitamins C and E. It also helps
fight tooth decay by binding CALCIUM to tooth enamel) including the transfer
of phosphate groups, the acylation of coenzyme A in the initiation of fatty
acid oxidation, and the hydrolysis of phosphate and pyrophosphate.
Magnesium is important for such functions as the activation of amino acids,
the aggregation of ribosome's, the binding of RNA to ribosomes and the synthesis
and degradation of DNA. It is essential for the formation of camp and other
second messengers and has a key role in neurotransmission and immune function.
Magnesium acts as a calcium antagonist and interacts with other nutrients, such
as potassium and boron.
Magnesium has an important role in regulating the neuromuscular activity
of the heart; maintains normal heart rhythm; necessary for proper calcium &
Vitamin C metabolism; converts blood sugar into energy.
DEFICIENCY SYMPTOMS:
May result in calcium depletion, heart spasms, nervousness, muscular excitability,
confusion; kidney stones, loose teeth.
The kidneys are extremely efficient in maintaining magnesium homeostasis;
therefore, primary deficiency in healthy individuals is uncommon. Symptomatic
deficiency usually is observed in the presence of a predisposing disease state,
such as severe malabsorption, chronic alcoholism, renal dysfunction, hyperparathyroidism
or the use of certain medications. Clinical manifestations of deficiency are
related to its role as a cofactor in enzymatic reactions, such as those requiring
ATP and in regulating neurotransmitters. Hypertension, arrhythmia, neuromuscular
manifestations, and personality changes occur during magnesium deficiency.
Clinical uses:
Magnesium supplementation may be appropriatein acute myocardial infarction,
arrhythmias, cardiac surgery, digitalis toxicity and congestive heart failure.
Magnesium toxicity is rare except in those with impaired kidney function.
Diet recommendations: The Recommended Dietary Allowances (RDAs) for
Mg are:
Usual dietary intakes in the U.S. are about 230 and 325 mg/day for women
and men, respectively. Canadian intakes are similar, but the Recommended Nutrient
Intakes (RNIs) are lower (200 and 250 mg/day for adult women and men, respectively).
