What is Calcium?


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 from the digestive system 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 IU/day is required). Vitamin K promotes the uptake of calcium into bone tissue. Many adults receive just half the amount of calcium they require from the diet each day. Calcium supplements are available in a variety of chemical forms, most commonly calcium carbonate, calcium citrate, calcium gluconate and calcium phosphate. The elemental calcium provided varies with chemical form, e.g. calcium carbonate provides 40% elemental calcium, whereas calcium gluconate provides only 9% elemental calcium. The lower the elemental calcium content, the more tablets that are required to meet recommended intakes.

 

What does Calcium do?


Calcium is responsible for maintaining healthy bones and teeth. Calcium is important for the maintenance of a healthy heartbeat, the transmission of nervous impulses and the contraction of skeletal muscles. Calcium also promotes healthy blood clotting, healthy blood pressure, and wound healing.


How much Calcium should you take?


The Recommended Daily Allowance for calcium has recently been revised by the National Research Council of the USA to 1000mg/day for men and women aged 19-50 years, and 1200mg/day for those aged 50-70 years.


Are there adverse effects from taking Calcium?


A daily calcium intake as high as 2500mg/day appears to be safe with no general adverse effects reported. Higher daily calcium intakes may cause gastrointestinal disturbance, interfere with the absorption of zinc, iron and magnesium, and lead to the formation of kidney stones in susceptible individuals. Patients with thyroid or kidney disease should take calcium supplements with caution. Calcium supplements may interfere with the action of the calcium channel blocking drug Verapamil.
