I think you might want to make a difference between what someone advocates - as compared to their results. I do not see - on a chemistry basis' (unless its something on the cellular level) how iodine is protective from free radical damage.Am interesting observation……
FM and Reefmoonshiners advocate daily dosing of iodine.
Most others recommend at least weekly dosing which suggests fairly rapid depletion- No?!
If there is rapid depletion and IF iodine is protective from free radical damage, then highest levels at the time of highest light trauma may be beneficial?!
Just thinking out loud…..
