I used to supplement with it but I tested negative for it so I stopped, haven't noticed much difference, but I think our mineral levels change from day to day...especially if we are using chelators....it really is a tough thing to nail down. Kind of hit and miss...so now I just use trace minerals in my water and sometimes I take a kelp supplement for the iodine. It is such an enigma!!!! <img src="/ubbthreads/images/graemlins/confused.gif" alt="" />

It is probably good to get muscle tested for it now and again, or you can even do it yourself...if you are a believer in that sort of thing.
