What is Coral Calcium?

Calcium supplements have become very popular and are generally thought to be an effective way to promote healthy bone density. Indeed, calcium does have benefits but it’s important to understand there are various forms of calcium and they all behave a little differently. Some supplements are worthwhile and some are merely the work of scoundrels trying to capitalize on false pretenses. Before you invest in a calcium supplement it’s wise to understand a few things about calcium.

What is Coral Calcium?

Calcium is available in many forms- calcium carbonate, calcium citrate, calcium orotate, and that just names a few. Coral calcium, a form of calcium carbonate, is exactly what the name implies. It is calcium sourced from fossilized coral sources and is the most common form of calcium on the planet. A small, invertebrate animal polyp secretes a limey substance that hardens into the coral structure. This substance is calcium carbonate. If that description creates questions in your head about the sustainability of coral calcium harvesting, you’re on the right track. Concerns have been raised as to the environmental harm from ravaging irreplaceable coral beds. Is it even worth it?

Is Coral Calcium Effective?

Calcium in the most simple form is rock, which the human body can’t process. To deal with this, the body has a natural method called “chelating” which simply means that the calcium is combined or “coated with” another material. This other material, which may be an amino acid, is a substance the body can use and process. Chelating calcium with such a substance is done in attempt to make the body use and process the calcium as well.

Calcium citrate, for example, is simple calcium carbonate “chelated” with citric acid. The citric acid is considered food by the body, so calcium citrate is more easily absorbed into the body than calcium carbonate.

The stomach can also chelate calcium, and does, but, the older we get the less the body can chelate minerals and make them useful. Some forms of calcium, such as calcium orotate, incorporate advanced absorption mechanisms into their structure and may be beneficial for such situations.

False Claims of Coral Calcium

How effective is coral calcium? Well, it’s hard to say. But, in January 2004, the Federal Trade Commission came down upon some calcium carbonate manufacturers for making improper claims about the abilities of calcium carbonate and making claims that a coral calcium dietary supplement was able to cure cancer, multiple sclerosis, heart disease, high blood pressure, and other serious diseases. The defendants were also reprimanded for claiming that the body absorbs coral calcium better than other calcium supplements. [1]

This is exactly why it’s imperative for you to investigate nutritional supplements on purpose and through research, not commercials! To market coral calcium with the promise of it being able to cure cancer isn’t just incorrect and ludicrous it’s immoral. Shame on them.

Coral Calcium Research

Coral calcium hasn’t provided many mind-blowing advances for the research community. The Department of Orthopaedic Surgery at Mahidol University in Bangkok collected samples of calcium carbonate salts and analyzed them for lead, cadmium and mercury. Every sample of the calcium carbonate contained lead. [2] A Japanese study with only 12 volunteers examined the effects of ingesting coral calcium via a cracker. Researchers did note a few interesting notes about observed absorbability but largely concluded that the data set was inconclusively small. [3]

Surprisingly, coral calcium has been shown to be useful in at least one application. A German surgeon had reported successfully using natural coral calcium for maxillofacial surgery bone grafting applications. [4]

Stick With What Works

For effective calcium supplementation, I only recommend calcium orotate. Calcium orotate is the single most effective form of calcium available. The orotate transfer system allows for calcium to penetrate into the cells that need it most.

    I beg to differ, I took some coral calcium in sachet form and put it in water and finally took the amount that I was told to take from the instructions for my body weight and it really gave me a superior but sneaky form of energy and had me flying up 3 flights of stairs to my apartment home and feeling great without huffing and puffing and being so tired and worn out as usual and I had a heavy bag of groceries in one hands and one or 2 gallons of water in the other. And usually it does not matter, I can have nothing in my hands and I would huff and puff, (just be out of breath) and in weakening pain climbing the stairs. But I whip up those stairs so quick and fast as if I ran up them. Anyhow, I felt so good and when I got up there, I said to myself, “What’s going on. How did I do that.” And the only change I could think of is that I started taking the coral calcium from in the of sachets that you put in water from okinawan oceans ( it’s sold in many places on the web) and I was feeling great. It was a sneaky form of energy, just quiet and natural. (No crazy bouncing off the wall.) But still you can do just as much. I felt as though I always had that energy. Until I ran out of the supplement and went back to poor energy levels and health. The only problems why I can’t continue to take it is the price for one month for my body weight would be too high. Also since the Japan Fukushima nuclear radiation explosion over seas scares me as it may have been able to penetrate somehow to the waters off the Okinawan down from it to those pristine coral reefs. Anyway if I could afford it $150 to $200 a month for my body weight and not to mention that’s just one supplement, but then again that’s all I was taking at the time, I would do it, but also the company would have to assure me that the radiation could not have gotten to those waters. But I don’t know if anyone could convince me of that.
