Does Coral Calcium Really Have Health Benefits?

On the Coral Calcium website, they make a lot of claims about their product having various health benefits, and even have some customer reviews saying that their health problems were cured. Can anyone tell me whether or not there is anything to these claims? I don’t tend to believe things just because a company makes these types of claims. I am wondering if maybe they might have health benefits if the problems were due to being short on some sort of vitamin or mineral that is included in this supplement. That is the explanation that makes the most sense to me if these claims are real.
