iodoral is definitely easier to take. it is reported to have less gastric upset as well. i found it to be a bit more potent, mg for mg. the best guess i have heard is that it arrives in the small intestines more intact to be absorbed directly into the bloodstream better. i dont know.
some people are putting drops in vegcaps and taking immediately with lots of water.
i find it hard to find the opportunity to take really large amounts of lugols. it is not pleasant and there is only so much water a person can drink in a day. one thing i have done is mix a strong shot of it and do a water chaser.
