Calcium, What's The Big Deal?

The big question about Calcium, exactly what is Calcium and why is Calcium so important to you and I?

What is Calcium?

Calcium is one of the most abundant micro-nutrient found in our body. 99% of our bodys total calcium is stores in the bones and teeth. The remaining 1% of calcium is then found throughout our body in blood, muscles, and the fluid in between cells. Calcium is also needed for muscle contraction and the secretion of hormones and enzymes. There are much more usage of Calcium, but to put simply, Calcium is important for Bone repair/formations and the contraction of muscles. Calcium is also the answer to strong and dense bones.

Different Types of Calcium, Which is Best?

Calcium is an element and it comes in various forms. Theres Calcium citrate, Calcium phosphate, Calcium Gluconate, Calcium Carbonate, and e.t.c. The list can go on and on, but which is the most common one that is best absorbed by the body?

There is something called the elemental weight. Calcium phosphate has an elemental weight of 31-38% whilst Calcium carbonate has an elemental weight of 40%. Lets use Calcium Carbonate (Most common form of Calcium found in the market) as an example, if you take 500mg of Calcium carbonate, only 200mg of elemental Calcium is available for absorption. Ill make things simpler by giving you an analogy; lets presume that youre now going down to the fuel station to pump some petrol for your car. There are 2 types of Petrol and both are mixed with water. For every liter of petrol, Petrol X contains 20% petrol whilst Petrol Y contains 40% petrol. We do know that cars require petrol to move and not water. So the obvious choice will be Petrol Y. The same goes to us, our body can only utilize elemental Calcium, and therefore, Calcium Carbonate is one of the better choices of Calcium supplements to take.

Vitamin D & Calcium Absorption

Taking Calcium alone is not as effective taking calcium with a good dose of Vitamin D. Vitamin D helps improve Calcium absorption. To put things simply, lets imagine things this way. Before calcium is absorbed by our body, it needs go through a door which is locked and requires a key to open it. Vitamin D is the key to opening this door to allow calcium into your body and from there allows the body to utilize the Calcium.

What NOT to Consume Calcium With

We should not be consuming Calcium with Zinc and Iron. This is so as our body prioritizes Calcium over the other two minerals. I advise you to take Zinc and Iron at a time when your body has little Calcium, preferably 30mins-60mins after drinking your milk. When purchasing multivitamins, do also look at the Nutrition fact sheet to see if any of this minerals are stashed together.

How much Calcium is Needed?

If youre just an average adult, I would recommend taking anything from 800mg 1200mg of Calcium a day. However, if youre an athlete or bodybuilder, you should be taking up to 2000mg 2300mg of Calcium a day. Good sources of protein include Milk, yoghurt, cheese. Taking more than 2500mg of Calcium may cause you to get wet stools.

Benefits

Calcium will help you maintain a healthy bone mass, delay the onset of osteoporosis and recent research articles have also shown that Calcium aids weight loss.
