I didn't know dicalcium phosphate would inhibit the uptake of magnesium, etc. Thanks for pointing that out. I will check my vitamins to see if they contain that. So basically you just take the vitamins needed for the Iodine protocol and nothing more? I'm so tired of taking so much. Also working on adrenals and just started Armour which seems to make my heart beat faster. So many supplements and I feel awful.
