From 1976 to 2021, I have done approximately 21, 7 to 10 juice fasts, with intestinal cleansing. Circumstances never permitted me to do a water fast for longer than 3.5 days. Recently I was introduced to the idea of a a water fast, while taking specific supplements. Also, recently I did this supplemented water fast for 3.5 days. The fast was much easier to do and I made more progress at improving my hyperthyroid symptoms. An injury in my low back that had been with me for two months also healed up on the fast. A correctly supplemented water fast produces superior results compared to a water fast alone.
