DESCRIPTION Calcium Citrate tablets, provided by Douglas
Laboratories, supplies 250 mg of elemental calcium
from calcium citrate. Calcium is a primary mineral
for building the strong structure of bones and teeth.
FUNCTIONS The adult human body contains approximately 1,200
g of calcium, of which about 99% is present in the
skeleton. Bone is constantly turning over, through a
continuous process of formation and resorption. In
children and adolescents, the rate of formation of
bone mineral predominates over the rate of
resorption. In later life, resorption predominates over
formation. Therefore, in normal aging, there is a
gradual loss of bone.
The remaining 1% of total body calcium is found in
the soft tissues and plays important roles in such vital
functions as nerve conduction, muscle contraction,
blood clotting, membrane permeability, and
hormonal signaling. Blood calcium levels are
carefully maintained within very narrow limits by the
interplay of several hormones (1,25-dihydroxycholecalciferol,
parathyroid hormone, calcitonin,
estrogen, and testosterone) which control calcium
absorption and excretion, as well as bone
metabolism. Levels of soft tissue calcium are
maintained at the expense of bone calcium in the face
of inadequate calcium intake or absorption.
Intestinal calcium absorption is generally higher in
children than in adults and ranges from 15 to 75% of
ingested calcium. Adequate vitamin D status is
necessary for normal calcium absorption.
Osteoporosis afflicts a large proportion of the elderly
in developed countries. Caucasian and Asian women
typically have low peak bone densities, and therefore,
are at the greatest risk of developing osteoporosis. It
is generally accepted that obtaining enough dietary
calcium throughout life can significantly decrease the
risk of developing osteoporosis. Among other factors,
such as regular exercise, gender and race, calcium
supplementation during childhood and adolescence
appears to be a prerequisite for maintaining adequate
bone density later in life. But even elderly
osteoporotic patients can benefit significantly from
supplementation with dietary calcium. Calcium
citrate is a highly available and well tolerated form of
calcium.
INDICATIONS Calcium Citrate tablets may be a useful dietary
supplement for those who wish to increase their
intake of calcium for maintaining the function and
structure of their bones.
