Chloride is okay. Whew! Chlorate is not.

The only down with chloride is that it is laxative if you take high doses. Some people can't tolerate that.

In US we have a delayed acting Chloride version called SlowMag, which is what I often use. I also use a powder that mixes into a liquid called Ionic Fizz...this has magnesium carbonate in it, and really works fast. When I need fast action, say due to some muscle problems, I use it instead of the SlowMag. SlowMag is my daily RDA form. It was originally developed by a the drug Company Searle, and now Purdue owns it, for cardiac care, but it is OTC and available for anyone to use without a prescription.

We had a person once come on saying in Britain he was taking snow melter--the stuff you throw on your icy sidewalks .. which I think would not be pure enough for oral use and may have heavy metals in it! So I do watch threads here carefully because of that possibility.
