Description: Microcrystalline Calcium 500mg 100c is available by Douglas Laboratories.
A Dietary Supplement
Calcium provided by Douglas Laboratories® is a dietary supplement
prepared from whole bone’s microcrystalline hydroxyapatite that is rich
in calcium, phosphorus, boron, bone matrix proteins, amino acids, and
glycosaminoglycans in their natural forms and physiological ratios.
Microcrystalline Calcium may be a useful
dietary supplement for anyone who wishes to increase their intake of
calcium and other nutritional factors for maintaining good bone health.
The adult human body contains
approximately 1,200 g of calcium, about 99% of which is present in the
skeleton. Bone is constantly turning over, 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.
1% of total body calcium is present 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, testosterone), which control calcium absorption and
excretion, as well as bone metabolism. Levels of soft tissue calcium
are maintained at the expense of bone in the face of inadequate calcium
intake or absorption. Osteoporosis affects 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 may benefit significantly from supplementation with dietary
calcium. Boron positively affects the structure and strength of bone,
and appears to be necessary for calcium and magnesium absorption, their
adequate renal reabsorption, and their incorporation into the bone
