I've never heard of this stuff before but it was recommended that I dose the baby up with it to help her immune system. I'm not hugely keen on spoonfeeding my daughter a heavy metal unless I'm sure it's going to be a benefit but the internet is somewhat lacking in information.
I've found
this page which seems like a load of shite, and the wikipedia page which doesn't really fill me with information.
Any of you lot use it?
