Re: Microsilica (edit)

Try researching microsilica on the internet. It comes in different grades, but even the better grades are inexpensive.

And you are certain that the better grades are equivalent to what is being offered here, or are you just speculating? Have you actually studied this product in a lab, or compared the results obtained from this product in a chelation regimen with those obtainable by using the cheaper sources you mentioned?

As for the "proprietary covalent metal binding group" that really means nothing. Silica in general can bind certain metals like aluminum.

That is irrelevantt in this case, since its stated purpose is to chelate mercury, not aluminum.

I have just seen too much sales hype from too many companies.

Also irrelevant, since "sales hype from other companies" doesn't have anything to do with what is going on with this product, and can in principle be used as an argument against absolutely anything, which means of course that it has no predictive value whatsoever. You haven't tried it, you haven't studied it, yet you are here to point out facts which are essentially irrelevant to the stated purpose of the product.
It has been endorsed by Dietrich Klinghardt, an authority in the field and a guy who has been doing metal detoxification in a clinical setting for over twenty years, so if it is really so easy to make, and overpriced by a factor of 10,000, you'd think someone else would jump in the market, undercut biopure, and make a lot of money, wouldn't you? That's usually how the free market works, in case you're not aware.

Of course the other hypothesis is that you have no idea what you are talking about. And for now, I'm fairly certain about which is more likely.
