I like your guess. Never thought of putting anything in the broth, have it a couple of times a month. Tried this summer everything in water and stopped did not feel well with it. Feel ok now just taking pinches of ES, a few drops of Lugol's and since I have a cold/allergy several times a day SSKI .
Also use water with DE. So far no leg cramps just on the ES. Might change again depending how I feel.
