Signs
and symptoms of magnesium deficiency or inadequacy can
include fatigue, mental confusion, heart disturbances,
irritability, weakness, muscle spasms, loss of appetite,
insomnia or a feeling of weakness. The Physician's Desk
Reference for Nutritional Supplements states that some
recent data of inpatient and outpatient populations,
suggest that magnesium deficits may exist in from 12%
to 40% of individuals.
Magnesium
supplements usually have their beginning as minerals
which have been influenced by our environment. For that
reason, the purity of magnesium raw materials is important.
Magnesium, like calcium, can have undesirable impurities
present. The responsibility to assure the absence of
lead and other heavy metals falls on the manufacturer.
Kirkman uses only the purest forms of magnesium which
have been tested for heavy metal content as well as
other impurities.
There
are many different forms of magnesium and the Physician's
Desk Reference for Nutritional Supplements states that
there is no compelling data indicating absorption differences.
There are reported differences in how different forms
affect the gastrointestinal tract, however. Below are
some guidelines, though individual results may vary
and should be discussed with your physician before administration.
Oxide Tends to firm stools
Glycinate A very gentle form, easier on the system
Citrate Tends to loosen stools
Sulfate Tends to loosen stools
Chloride Tends to loosen stools
