There is a theory that if you absorb throught the skin quickly, then you are Iodine deficient. However, I've found that it depends on whether you use lugols, or povidone-iodine, if you use certain creams, you seem to absorb more quickly. I went through a period of hardly absorbing anything overnight, but now I'm absorbing almost all the Iodine in a few minutes. Wierd.
