I use 1 drop every other day. Again my understanding about the usefulness of Iodine and its functioning in the body comes from Dr. Jarvis and his many examples
about why it is so. I realize he is not the last word on this topic but I trust
his simple and very conservative approach with respect to working with the human condition both emotionally and physically. He was also very much aware of diet, behavior and environment as a method for maintaining good health.
