I had been taking Iodoral and Iosol Iodine without any problems but as Lugols is cheaper I have been taking it in the same dosage as the other two and I have an icky tummy kinda like heartburn now. Is Lugols more harsh on the stomach or does it affect stomach acid as I often have the problem of low acid which I fix by taking a HCL supplement. Or do you think I just have low stomach acid and it's nothing to do with lugols? I would appreciate any answers from all the experts here. Thanks
