No Rick did not eleborate on this that I can remember. But I saw this on one sight I was researching magnesium .
I would think you need to have your thyroid in good working order then the magnesium oil will help.
It made sense to me my thryoid has been working for a year with no support and then I add more magnsium then I ever used before.
I use LIfe Flo only $10 and if you put it on certain areas it will not burn. Rick did inform us that putting it by the belly botton is the best place for absorbtion...no buring there. I do use it often do to low magnsium level and tryin gto build up a reserve to beable to get off the hydrocortisone all the way.
