"If it is that dangerous, I don't think ALA would be sold as a supplement?"
I think it is available only with a doctor scriipt in Germany.
The chelating ability of ALA is not well known to doctors and the implications for inorganic mercury in the brain is hardly known at all.
"When you say safety I always wonder about the people who know nothing about chelation and take ALA regularly or on and off. I guess those people are probably very sick from using ALA wrong?"
The folks who don't have a mercury problem will benefit from ALA's various benefits--antioxidant, etc.
In the Yahoo groups we've seen a number of startling reports from those who have a mercury problem.
-I know a guy at work who has gotten nice improvement in his neuropathy from inappropriate use of ALA; however he looks really foggy and whifty even though he is obviously well educated. He reminds me of my foggy brain before I started to chelate. This is doubly sad because he has a teenage high-level autistic son. The boy would likely benefit from appropriate use of ALA and the boy needs his aging father to be sharp and healthy to help him heal!
