What is Naturally Desiccated Thyroid?

Desiccated porcine thyroid, sometimes referred to as natural desiccated thryoid (NDT), is derived naturally from the glands of pigs. It has been used for almost 100 years to improve symptoms of hypothyroidism. Each dose of NDT contains multiple thyroid hormones and thyroid co-factors. Many patients and doctors prefer this effective, non-synthetic way of increasing hormone levels because it includes both active and inactive forms of the thyroid hormone. Our compounded thyroid contains:

  • T4 & T3 replacement hormones derived from natural desiccated porcine thyroid
  • Naturally occurring thyroid cofactors T1, T2, calcitonin and iodine (in trace amounts)

Our pharmacy compounds NDT capsules to match the dosage of any formulation currently under shortage or that is discontinued.
