absolutely. My levels dropped dramatically. The two things that helped me the most was diet for yeast problems. The best thing for this is Formula SF722. This is the only thing ive taken that ever sorted my candida problem. Everything else failed. Then i took Chorella and built the doses up. This gets rid of mercury and contains iodine which is good for your thyroid. As for stuff like thyroxine and armour none of them work or will work because youre probably not converting. Taking them will make it worse more than likely.
