Preparasyon òmòn tiwoyid apatni a de kategori: (1) preparasyon natirèl ormon ki sòti nan tiwoyid bèt, ak (2) preparasyon sentetik. Preparasyon natirèl yo enkli tiwoyid epatit ak tyroglobulin. Se tiwoyid ki dewize ki sòti nan bèt domestik ke yo itilize pou manje pa moun (swa vyann bèf oswa tiwoyid kochon), ak thyroglobulin ki sòti nan glann tiwoyid nan kochon an. Etazini Pharmacopeia la (USP) gen estanda total kontni yòd nan preparasyon natirèl. Tiwoyid USP pa gen mwens pase (NLT) 0.17 pousan epi li pa pi plis pase (NMT) 0.23 pousan yòd, ak thyoglobulin gen mwens pase (NLT) 0.7 pousan nan yòd òganikman. Kontni yòd se sèlman yon endikatè endirèk nan aktivite reyèl byolojik ormon.

Thyroid hormone preparations belong to two categories: (1) natural hormonal preparations derived from animal thyroid, and (2) synthetic preparations. Natural preparations include desiccated thyroid and thyroglobulin. Desiccated thyroid is derived from domesticated animals that are used for food by man (either beef or hog thyroid), and thyroglobulin is derived from thyroid glands of the hog. The United States Pharmacopeia (USP) has standardized the total iodine content of natural preparations. Thyroid USP contains not less than (NLT) 0.17 percent and not more than (NMT) 0.23 percent iodine, and thyroglobulin contains not less than (NLT) 0.7 percent of organically bound iodine. Iodine content is only an indirect indicator of true hormonal biologic activity.
