hi bex : on page 52 figure 15 , it looks like a brain mercury chart ,and how you will feel doing different potocols,unless I am reading it wrong , item d shows the worst effect not using any chelation at all and shows brain mercury going up very high at 6-9 months and then on page 76 nine paragraphs down it mentions that if not using ALA ,that brain mercury will never removed from the brain ,but also mention in the same paragraph that if dmsa is used alone it will remove brain mercury but will take a little bite longer ( confused)??????????
