Description: Calcium Citrate 250mg 250t is available by Douglas Laboratories.
A Dietary Supplement
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.
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.
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.
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.
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.
