It's primarily tied to estrogen, as estrogen stimulates proliferation of prolactin-producing lactotrophs of the anterior pituitary; it's why AIs also lower prolactin.how do you lower prolactin ? without things like lisuride or others
Accordingly, vitamins D, K2 and E, b-vits, thyroid, progesterone, etc, are all effective interventions.
High dose vitamin D + B6 will put my prolactin below range.
