i would take both elemental and iodide. elemental is the corrective element and the salt is more like food/nutritional. take lugols in water only on an empty stomach for the best effect.

i got up to 300mg of lugols a day before i thought it was a little too much. i then switched to the salt and was soon taking it by the gram.

be well

edit: i forgot about doctors. some know more than others, but that bar is pretty low to begin with. i believe that some cancers are a direct result of iodine deficiency. i also believe that iodine is beneficial for remission of all cancers and probably essential to remaining in remission. its always a good idea and makes everything work better, it seems. your mileage may vary.
