YESSSS! I've used SF722 and have some on my kitchen table as I write. I use it every so often when I have stomach issues. It works GREAT. Thorne products are the top of the line and many holistic and naturalpathic doctors swear by them. I also love the fact that I get NO side effects from using SF722, just relief. If you want to gain a bit more knowledge about candida and fungus, this link has great articles. http://www.know-the-cause.com
About the mercury testing. After reading this forum and many books about mercury poisoning, I have come to the conclusion that's it's almost impossible to get a read on the body"s burden of mercury. What really is a big problem is that almost everyone has a very high mercury content in their body BUT(big but) not everyone exhibits symptoms or symptoms that correlate to mercury poisoning. I would definitely say that the posssiblity is high you have a mercury problem if you had any amalgam fillings in your teeth at any time in your life.
