Re: coral calcium?

I also have been searching for information about coral calcium. I am having trouble finding any from an objective source. I am not discounting Mr. Barefoot's expertise, but keep in mind that he wants to sell this product. There was an interesting article in the January 2003 issue of Prevention magazine, p. 65. I am just a little leery of information given to me on a product, given to me by someone trying to sell that product.
