Question: What's the safe use of an iodine nasal spray?So, the iodine in the food and supplement guide for the coronavirus most recent version, I included iodine as a nasal spray. It's very important to look at the percentages. And so, 0.5% is the concentration recommended and that means that if you get a 10% solution, which is the most common one, you want to dilute it down 20-fold, which means taking one part of the 10% solution 19 parts water. If you have a different percentage starting solution, you wanna dilute it differently. And it's critically important that you dilute it properly. And so, you should have someone double check your work if you're doing your own math or triple check your work because higher concentrations can cause damage to the nasal tissue. But in terms of how often what I recommend doing is using it as a before and after in potential exposures. For additional important safety information please see here:
