Calcium is the most abundant mineral in the human body, which contains approximately 1.2 Kg, 99% of which is stored in bones and teeth, with the remaining 1% present in the blood and other bodily tissues. The skeleton acts as a reservoir for calcium; if the intake of calcium is insufficient, bones become depleted in calcium.
Extended Info
Calcium is the most abundant mineral in the human body, which contains approximately 1.2 Kg, 99% of which is stored in bones and teeth, with the remaining 1% present in the blood and other bodily tissues. The skeleton acts as a reservoir for calcium; if the intake of calcium is insufficient, bones become depleted in calcium.
Dietary sources of calcium include dairy products, fish and some green vegetables. Oxalic acid, which is found in some green vegetables like spinach, is a potent inhibitor of calcium absorption. The body is best equipped to absorb calcium and build up bone tissues up to the age of 35, after which bone density is lost at a rate of approximately 0.3% per year (1% in post-menopausal women). Calcium cannot be absorbed without vitamin D, which is made in the skin in response to sunlight (vitamin D levels decline with age, and a daily intake of 200-400 mcg/day is required). Many adults receive just half the amount of calcium they require from the diet each day.
Comments
Cautions
A daily intake as high as 2500mg appears to be safe with no reported adverse effects.
Higher intakes may result in gastrointestinal disturbance, interfere with the absorption of zinc, magnesium and iron and may lead to formation of kidney stones in susceptible people. People with thyroid or kidney disease should take calcium supplements with caution. Calcium supplements may interfere with the action of the calcium blocking drug Verapamil. Pregnant or lactating women and those on medication should consult a doctor before using any product
