I would definitely not trust the unknown heavy metal supplements and blends, like the one you're using. If you haven't already, I would try to find out if other people have used it successfully.
The fact that you're not feeling anything while using it is a sign that it's probably not working (you probably know that if it's working, you should be feeling at least a little worse while using it).
If I were you, I would stick to one of the methods which people have used successfully.
What symptoms do you have while using ALA? I think you wrote about it before, but I've forgotten.
