We have gone through multiple times, if you want to continue with enervating practices, then do so.
No supplements. Your body needs to work out all the deficiencies one has created by eating wrong foods, if you supplement, your digestive system stays active, it draws other nutrients from the reserves to compensate for what is missing, sure way to get in starvation mode.
Please just fast with water and see the magic of your body and fasting.
You are trying to fix things externally when your body is doing that for you internally while fasting, give it a chance. Don't panic and come up with ideas to fix every symptom you face.
You can start Iodine protocol after you complete your fast and refeed for equal number of days to your fasting days.
