"I don't know if it's the small amount of Iodine in the kelp or something about the cod liver oil... ...also taking black strap molasses and a fulvic acid mineral supp."
All these are working synergistically, the kelp and cod liver oil with a healthy gut flora would do this alone, however with the addition of fulvic acid minerals and molasses, you have a very powerful combo going.
Do you eat cultured foods? ... that would about round all this out very well.
