NP Thyroid is a natural desiccated thyroid hormone preparation containing both levothyroxine (T4) and liothyronine (T3), the two primary hormones produced by the thyroid gland. Thyroid hormones regulate metabolic rate by binding to nuclear thyroid hormone receptors in nearly every cell of the body. Because it contains both T4, which serves as a reservoir hormone converted to active T3 in peripheral tissues, and direct T3, this formulation is designed to closely mirror the thyroid gland's natural hormone output pattern. EdgeRx may prescribe NP Thyroid for eligible patients with lab-confirmed hypothyroidism, as part of a clinician-supervised protocol involving regular thyroid panel monitoring.
