74% of adults are iodine deficient. Iodine is required to make T3 and T4, if the body doesn't have enough of these thyroid hormones then the hypothalamus secretes TRH (Thyrotropin-releasing hormone)which releases TSH (Thyroid-stimulating hormone) and prolactin (1). Prolactin, as we all know, is antagonistic to dopamine. The TSH that is released from the anterior pituitary gland further lowers dopamine (2). If the thyroid doesn't create T3 and T4 the TSH levels keep climbing, and dopamine will keep dropping.
(1) TRH increases prolactin and decreases dopamine http://www.ncbi.nlm..../pubmed/6796383
(2) Dopamine antagonist raises TSH http://www.ncbi.nlm....v/pubmed/436307
I'm currently on Iodine (5mg/day) and the Mr. Happy Uridine stack, and there is some nice synergy here; I feel balanced, happy, energetic, and my imagination is vivid and alive again.
