Why we need Calcium and why it is important in our body?

Calcium is a mineral. It is vital for the formation of strong bones and teeth and for the maintenance of healthy gums. Calcium lowers cholesterol levels and helps prevent cardiovascular disease. It is also important in their maintenance of regular heartbeat and in the transmission of nerve impulses. This is also important in blood clotting and helps prevent cancer. it also helps to keep skin healthy and protect against the development of preeclampsia during pregnancy. If high blood pressure develops due to pregnancy, it can be reduced by calcium intake.Calcium also protects the bones and teeth from lead by inhibiting absorption of this toxic metal.

Female athletes and menopausal women need a greater amount of calcium than other women because their estrogen levels are lower. Estrogen protects the skeletal system by promoting the deposition of calcium in the bone. A diet that is high in protein, fat and sugar affects calcium intake Oxalic acid (found in almonds, cashews, cocoa, kale,soybean, rhubarb, and spinach) can also combine with calcium to form calcium-oxalate kidney stones, however taking supplements of magnesium and potassium supplements can
prevent the formation of this type of stone. Heavy exercising hinders calcium intake but moderate exercise promotes it.

Calcium supplements are more effective in smaller doses spread throughout the day and before bedtime. Calcium if taken in single mega doses will be less effective. Most experts agree that no more than 500 mgs. should be taken at one time, as this is the maximum amount the body can absorb in one dose. Calcium also promotes a sound sleep when taken at bedtime so therefore it is best to take it at night because a high fiber diet can interfere with calcium absorption.

It is not advisable to purchase calcium with compound D1- calcium-phosphate in their products as this form of calcium is insoluble and interfere with the absorption of nutrients in a meal nutrient supplement. Antacids such as Tums is not recommended as a source of calcium. They do contain calcium but if taken in sufficient quantities as a source of this mineral, they would also neutralize stomach acid needed for the calcium
absorption. Also, people age over 60 about 20 to 40% may have a condition called strophic gastritis. This is a chronic inflammation of the stomach, and it reduces the ability to break down the calcium carbonate contained in Tums Phenobarbital and diuretics may cause a deficiency in calcium.

Calcium may also interfere with the effects of verapamil (calan, isoptone, verelan), a calcium channel blocker sometimes prescribed for heart problems and high blood pressure. It also can interfere with thyroid hormone, steroids, certain anticonvulsants and the effectiveness of tetracycline. Calcium is found in dairy products, salmon (with bones), sardines, sea foods, green leafy vegetables, yogurt, soybeans, tofu, almonds, broccoli, collard greens, kale, kelp, cabbage, cheese, goat's milk, mustard greens, prunes, figs, sesame seeds, lemon grass (tanglad) and flax seeds.

Calcium deficiency can lead to elevated cholesterol levels, high blood pressure, aching joints, brittle nails, heart palpitations, numbness in the arms and legs, insomnia, muscle cramps, rheumatoid arthritis and tooth decay and a pasty complexion. Additionally, it is also associated with cognitive impairment, depression, delusion and hyperactivity and convulsion.
