MAGNESIUM
The eighth most abundant
element in the earth’s crust
How it functions in
body metabolism



Approximately 50% of total body
magnesium is found in bone. The other
half is found predominantly inside cells of
body tissues and organs. Only 1% of
magnesium is found in blood, but the
body works very hard to keep blood
levels of magnesium constant.
Magnesium helps regulate blood sugar
levels, promotes normal blood pressure,
and is known to be involve in energy
metabolism and protein synthesis.
Magnesium is excreted through the
kidneys.
Can it be synthesized by
the human body or must
it come from other
sources

Magnesium is a mineral, so
therefore just like calcium,
magnesium must be absorbed
through dietary intake.
Food Sources

because the center of the
chlorophyll molecule(which gives
green vegetables their color)

Deficiency/Disease
Treatment



Hypomagnesemia, resulting in low blood
calcium levels, muscle cramps,spasms
or seizures, nausea, weakness, irritability
and confusion
Chronic diseases such as heart disease,
high blood pressure, osteoporosis and
type 2 diabetes
Early signs of magnesium deficiency
include loss of appetite,
nausea,vomiting,fatigue,and weakness
Fun Facts


“HARD” water contains more
magnesium than “Soft” water
Craving chocolate? Take some
magnesium to help take the
cravings away
CALCIUM
The most abundant mineral in
the human body.
How it functions in body
metabolism



More than 99% of total body calcium is
stored in the bones and teeth where it
functions to support their structure. The
remaining 1% is found throughout the
body in blood, muscle, and the fluid
between cells.
Calcium is also critical for the normal
transmission of nerve impulses. Calcium
flows into nerve cells and stimulates the
release of molecules called
neurotransmitters.
Calcium also plays the role in muscle
contraction, healthy blood pressure, the
initiation of blood clotting, and the
regulation of various hormones and
enzymes.
Can it be synthesized by
the human body or must
it come from other
sources

Your body needs calcium to
build and maintain strong bones
and teeth. You must absorb
calcium every day from your
dietary intake because your
body does not make calcium

There is a widespread concern that
Americans are not meeting the
recommended intake for calcium.
According to the Continuing Survey of
Food Intakes of Individuals (CSFII 199496), the following percentage of
Americans are not meeting their
recommended intake for calcium:
44% boys and 58% girls ages 6-11
64% boys and 87% girls ages 12-19
