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. 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. 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. Adults take 1 tablet daily or as directed by
physician. No adverse side effects reported. Store in a cool, dry place, away from direct
light. Keep out of reach of children. Bendich A, Leader S, Muhuri P. Supplemental calcium for the
