Calcium is vital for the optimal functioning of the entire body. It is common knowledge that our body needs calcium for development of bones and teeth. What is generally not well known is that, calcium is the cellular cement for bones; it is required for proper functioning of the muscles, transmission of nerve impulses and for clotting of the blood. There is more to calcium than strong bones and teeth.

What does Calcium Deficiency Do to the Body?
If your diet does not provide enough calcium for your body, or if your body is unable to absorb the calcium from your diet, it may start withdrawing the calcium from your bones for various body functions. If the depletion of calcium from the bones continues, it could lead to osteoporosis and various other complications arising out of it. Studies indicate that a higher intake of calcium leads to increased bone density and reduced risk of fracture.

How to Increase Calcium Absorption?
Vitamin D promotes the absorption of calcium. Without Vitamin D your body cannot produce enough of the hormone calcitriol, which is known as the active Vitamin D. Vitamin D helps in the absorption of calcium in the intestines.
You can get Vitamin D in three ways –
- When the ultraviolet rays of the sun strike the skin, it triggers the synthesis of Vitamin D.
- You could also get Vitamin D from your diet. Food sources such as cod liver oil, cooked swordfish, salmon, canned tuna, sardines canned in oil, liver, beef and fortified cereals, juices, yogurt and dairy products are rich in Vitamin D.
- Supplements and fortified foods are another way to get your requirement of Vitamin D.
Factors that Inhibit Absorption of Calcium
- One fact that you need to be aware of, is that a high protein diet over a prolonged period of time causes calcium to be excreted in urine.
- Excess salt in your diet could also cause the same reaction. People with calcium deficiency need to reduce their level of protein and salt intake to increase their calcium absorption.
- Drinking sodas regularly depletes the calcium in your bones. Your body tries to balance the phosphates in the sodas by drawing calcium from your bones. This is later excreted through urine.
Calcium supplements are absorbed better if they are taken in dosages of 500 mg or less at a time. It would be more beneficial to spread it throughout the day. Calcium supplements are better absorbed when taken with food. Just taking calcium supplements alone would not be of great help. It is important to get a little exercise to strengthen your bones, no matter how old you are.
Calcium Side Effects
Before you go off to take calcium supplements, you need to consult with your doctor. Excess calcium in your diet could lead to high levels of calcium in the blood. This impairs kidney function. It also results in kidney stones, causing a lot of pain. Too much calcium also causes fatigue, depression, nausea, vomiting, constipation, etc. You could also develop irregular heartbeat and low blood pressure, which could be dangerous. You need to be cautious about taking any supplements on your own. Moderation and a balance in everything you do is important, and that includes your diet.
