You should not just stop taking your thyroid meds. There are no supplements or minerals or foods that will substitute. The result was predictable-- a high TSH and a FT3 and FT4 just within the low limit of the "normal" ranges. All three of these test results are indicators of being hypo. You need to get back on your thyroid meds and keep adjusting your FT3 and FT4 levels until symptoms are relieved. Frequently this requires FT3 in the upper part of its range and FT4 around the midpoint of its range, without regard for the resultant TSH level.
When it comes to bioidentical hormone replacement, I am a cynic. I am suspicious of the way it is advertised and also there's the cost. If you want bioidentical thyroid hormone, just use a T4 med, or go to a dessicated, natural T4/T3 med and get your FT3 and FT4 levels up to where they need to be. I have a hard time believing there would be additional benefit going to the higher cost bioidentical version.
can you post the links you read on the bio identical replacement?
