Cool, I'm a big advocate of moly. I've been using it for over a month and did a 120 day protocol of 300mcg per day. Unfortunately, it didn't seem to have an effect on tooth sensitivity for me, at least not in the situations I described. I haven't done any research on strontium, but I have used Concentrace which I know contains it. I tend to get very dry skin the day after using it, I'm guessing from the high content of magnesium, but it could also be from the high chlorine competing with my iodine. Iodine was a major skin moisturizer for me. Hopefully, I'm getting my strontium from something I eat.
