A natural desiccated thyroid of porcine origin/Many individuals managing hypothyroidism (low thyroid production) prefer natural desiccated thyroid supplements of porcine origin./The appeal often lies in these supplements containing a complete profile of thyroid hormones, including T3, T4, as well as the less discussed T1 and T2./Additionally, it is noteworthy that porcine thyroid is bioidentical to human thyroid. Despite becoming harder to source in recent years, leading to higher prices, we are excited to introduce ThyroidPro, natural thyroid extracts from Spain. These are available in sizes of 1/2 grain (30mg), 1 grain (60mg), and 2 grain (120mg), offered at reasonable prices./Please note that these supplements are not suitable for vegetarians.
