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-dihydroxy-cholecalciferol, 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
