Hi Rachie, there is no issue with the powder at all. Ive had it in my mouth and nothing. ANd I am very sensitive to anything and severely for a long period of time. So that should reassure you. The only issue is the ALA can burn a bit on the tongue if I recall.

Other than that, they are fine. DMSA is used on children to chelate them and it is ok for the most part. Some do find they dont tolerate the DMSA itself, but mostly it is the mercury being moved that is the issue.
