The Health Benefits of Calcium. Link with treatment and prevention of osteoporosis, pre-menstrual syndrome, preventing pre-eclampsia in pregnancy, parathyroid disorders. May help with cardiovascular disease, hypertension, hyperlipidemia, stroke and certain cancer preventions but more research is needed.

Calcium is an essential mineral for living organisms and the most abundant mineral in the human body. It is an essential element for development of bones and teeth as well as many intracellular signaling processes. Normal calcium levels are required for normal vascular function, muscle activity, nerve transmission, intracellular signaling and hormonal secretion. More than 99% of calcium is stored in the bones and teeth, and only 1% or less is circulating for other purposes.
Calcium metabolism is tightly regulated by the body and in most healthy individuals, it will not fluctuate much between dietary intakes. Your body depends on magnesium, phosphorous, vitamin D and vitamin K for proper balance of your calcium levels. Because of this, as you can imagine, malnourished individuals are at risk of having low calcium. Other factors, such as age, chronic diseases and certain medications can affect calcium absorption and metabolism.
Certain things may enhance calcium absorption, such as carbohydrates, while others such as coffee and cigarette smoking may impede it. Once absorbed, bone continuously undergoes remodeling, with constant reabsorption of calcium and deposition of calcium into new bone. In children, deposition exceeds resorption, leading to bone growth at the growth plates. In adults, this process is typically in equilibrium until we get into the later years of life, particularly in postmenopausal women where reabsorption exceeds deposition.
Dietary intake and supplementation is most closely linked with prevention or treatment of osteoporosis, but also appears to help with pre-menstrual syndrome, preventing pre-eclampsia in pregnancy, and treating hypoparathyroidism
It may help with cardiovascular disease, hypertension, hyperlipidemia, stroke and certain cancer preventions but more research is needed.
Deficiency in children is termed rickets, in adults it increases your risk of osteopenia and osteoporosis leading to fractures
The best dietary sources are cheeses, dairy, yogurt, soy, sardines and orange juice
The recommended daily allowance varies somewhat depending on age, gender and pregnancy status but is roughly 1000-1200 mg per day.
