ThyroSync is a targeted formula combining key nutrients and botanicals that work together to optimize thyroid function. It includes L-tyrosine and iodine, which are essential building blocks for the thyroid hormones thyroxine (T4) and triiodothyronine (T3). Zinc, selenium, vitamin A, and guggulipid further support the efficient conversion of T4 into the active T3 hormone, while improving cellular responsiveness to these hormones.
