This is a product I have not used but is very well reputed. Apparently the body pH has to be almost perfectly balanced for the usability of iodine; atomidine is a very bioavailable form of Iodine that has been around many years but apart from Cayce enthusiasts, isn't well known or much talked about. Cayce recommended it for many people with thyroid issues and symptoms e.g. from poor circulation and eliminations, to hairloss, etc.
