comparing magnascent to Lugols is like comparing a 90lb guy to arnie in his prime and then saying they can both pick up the same amount of weight. this is true about how effective magnascent is in very small doses. thats why i say get cheap KI and take that as your main suppplement and dance the magnascent on top, be it a drop or fifty of them. it all depends on what you need it for and how much works for you.
there is another possibility and that is you are not absorbing any of the Iodine from either source. vitamin C is in order - at least 3 grams a day. 3 grams 3 times a day if necessary, or more.
