Active Ingredients
Thyroid USP
Nature-Throid™ Tablet is a full prescription, officially
monographed United States Pharmacopeia (as Thyroid USP)
medications for treatment of hypothyroidism. They are
natural preparations derived from porcine thyroid glands (T3
liothyronine is approximately four times as potent as T4
levothyroxine on a microgram for microgram basis) and
provide standardized, guaranteed potency of 38 mcg
levothyroxine (T4) and 9 mcg liothyronine (T3) for each 65
mg (1 Grain) of the labeled content of thyroid.
Thyroid USP has been frequently referred to as Natural
Desiccated Thyroid (NDT) with NDT treatment being introduced
towards end of the 19th century. However, unlike the NDT
treatment at its beginning, USP (United States Pharmacopeia)
has established specific standards on the presence of T3 and
T4 hormones among others to classify this ingredient under
full prescription status.
Currently, there are desiccated animal glandulars within the
Dietary or Nutraceutical status indicated as a Thyroid
Gland, for example. However, this is not to be confused with
the USP designation. Only the USP monographed ingredient
adheres to full pharmaceutical purity and standardization on
the consistency of the hormones along with full pre and post
testing procedures associated with quality prescription
products. All NON-USP glandulars have natural fluctuation
and variances of hormones making any consistent therapeutic
values difficult to control.
