i never had a problem drinking tons of homemade Colloidal Silver for a couple of months. i did and still do eat fermented foods and yoghurt and such. i was on a kimchi kick back then.
that aside, i think you will be quite please with the additional iodine. like Colloidal Silver , it is dose dependent. trapper maxim: with iodine, it is easy to take too little and very hard to take too much. trolls to the contrary, of course.
