Calcium is essential for complex life.\n\nFirst of all, calcium is essential for our nervous system to operate properly. When an action potential reaches the end of an axon, it causes calcium to rush into the axon terminal. This stiumulates the release of neurotransmitters into the synaptic cleft. Without calcium, transmisson of signals in the nervous system would be impossible.\n\nSecond of all, calcium is essential for muscle contraction. When a muscle is stimulated to contract, calcium rushes out from the sarcoplasmic reticulum and binds to a molecule called troponin. This causes a conformational change in tropomyosin, which allows actin and mysin to bind and the muscle to contract. Without calcium, muscle contraction would be impossible.\n\nThird of all, calcium is essential for the formation of bone. Without the structure and support provided by bone, we wouldn't be much of anything.\n\nSo, calcium is most definately important for life, especially complex life.

You need to have your minerals in balance, so besides calcium, you should be taking a magnesium supplement also.  If you are drinking milk, 2 or 3 8 oz glasses a day are good.  Magnesium is not in a lot of foods (it's high in almonds and buckwheat), so I find it's easier to take a supplement.\n\nYou should be able to find a magnesium/calcium supplement because these two minerals are known to work together.  If you are looking at an age of bone loss, at least 1 gm (or 1,000 mg) of each is a good amount.\n\nI have entered into menopause myself.  Having been a big milk drinker (at least a quart a day) for all of my life, I have pretty strong bones - at least that's what I've been told when I've gone for bone density scans (my readings are off the charts on the good side).\n\nOn calcium and magnesium - if you want to get them from foods, the best source for both is bone broth that you make yourself from chicken, beef or pork bones.  It's the most bioavailable form for all minerals.

truthfully, it hasn't been completely labeled as  beneficial. yes, it does have calcium, vit d, etc, but some studies actually show that our bodies don't digest them properly.  if anything, it keeps you hydrated. humans are kinda strange though... do you realize that we are the only species that drinks milk long after infancy? lol not to mention, another species breast milk. yum!

Calcium is the main ingredient in bones. Bones are the frame work or "steel Support" of the body. Muscle are attached to the bones, yes they do the lifting and pulling part  but they need a good achor and lever system. It does no good to have a strong muscle if the the item it is attached to will snap.

There are no dangers in taking calcium or vitamin D long term.Vitamn D is fat soluble so do not oerdose. \nWith diagnosed osteoporosis, there are drugs that can put bone back  on if the patient can tolerate them. (sit up for 1/2 hour after taking them)\nExcercise is also important for osteoporosis.Weight bearing excercise such as walkingis very good. \nGet a good dit with a good variety of fruits and vegetables.

Parathyroid hormone will act to increase your blood calcium levels. It will first go to the intestines to see if it can get calcium, next it will affect the kidneys to reclaim calcium and prevent it from being lost in urine, and finally it will take if from your bones. Taking it from bones is the last thing you want to happen as this will lead to osteoporosis.

Taking calcium together with magnesium supplements are your best bet.  Magnesium aids in absorption.  Milk has calcium but unfortunately your body needs a lot of calcium to digest the high protein content in milk so milk actually makes you calcium deficient.

mostly  gene can do  long  bone ... \nbut calcium is good for growth ..

Jeeze... OK, people... please realize that bones are connected to mammary glands, though the connection is not a direct one...  \n\nBones are made of mineralized proteins. That is, they have a loose structure made of proteins, which are like fibers (think of the protein as like rebar in concrete) around the protein (rebar) are placed minerals (cement) such as Calcium and Phosphate ions. When breast feeding, a woman needs calcium to be available to make milk, but obviously her body doesn't want to liberate all of her bones' calcium. Two hormones regulate calcium levels in the blood, Calcitonin and Parathormone. Parathormone (parathyroid hormone) increases blood levels of Ca, whereas calcitonin decreases blood levels of Ca. These hormones either stimulate bone cells to free Ca into the blood, or put it back into bone, respectively. When nursing, the mother is, of course, using some of her Ca reserves. It's important to note, though, that much of this is replaced by diet, and that there are hormonal checks in place to make sure Calcium depletion doesn't happen. So, no, a healthy woman with a good diet can nurse all she wants. Calcium supplements are not a bad idea, though.\n\nAlso, for God's sake, we don't produce Calcium! It's a mineral, and we have to get it from our diet.

well, for one, calcium is inorganic, so incapable of reproduction. if anything grew, it would most likely be a fungus from under your fingernails or just in the soil.

Calcium. When I have had broken bones, I crave milk and the doctor said my body is needing the calcium in it. Drink and eat lots of calcium rich foods. Also a good calcium supplement pill or capsule will help.

calcium is maintaind in the blood by the action of parathyroid hormone and calcitrol\nReceptors monitor the level and if it is low, parathyroid acts on bone to release calcium and increase intestinal absorption, if it is high the hormones act on bone to bind more calcium and the gut to stop absorbing it

kal'el, that's calcium...I think vitamin D helps your body ABSORB the calcium...

Vitamin D allows Calcium to be absorbed in your system.  Without it, the calcium just passes through.  I would suggest getting some calcium supplements (usually less than $20 for a month supply) which usually contain Vitamin D also.  Exposure to the sun also gives you Vitamin D so be sure to get plenty of sunshine!

Depends on how much calcium you want.  The best source for large amounts of calcium would be a Ca supplement.  Naturally, milk and dairy products are a good source.
