Thyroid USP (GMP)

Thyroid USP is easily absorbed by human body and shown to have less side effects compared to synthetic drugs in the treatment of Hypothyroidism


Thyroid disease, in particular, Hypothyroidism, is one of the most common chronic diseases worldwide, affecting approx. 5 % of the global population, with main symptoms such as metabolic dysfunction, fatigue, stagnated growth, cardiovascular diseases, and infertility (1; 2; 3; 5). Despite the fact that synthetic thyroid hormones (T3 and T4) have been used for a century to treat hypothyroidism, it is estimated that up to 15 % of treated patients remain symptomatic while receiving synthetic mono-therapy with T4 hormones (2; 3; 5).


Target application is pharmaceuticals and compounded drugs.

By taking advantages of our 75 years of expertise in the pharmaceutical and nutraceutical industries, BIOFAC has listened to clinicians’ and patients’ requests for a natural combination T3/T4 thyroid extract product,
as it comprises:


Various forms of thyroid extracts were originally developed in the 1880s and were used as primary treatment. In the 1970s, there was a switch to T4-mono therapy, which to this day is the standard of care, considered safe and effective (7). Studies show that patients receiving synthetic mono-T4 therapy prefer and respond positively to combination therapy with natural thyroid extract (T3 + T4) due to fewer side effects (6; 7). Combination therapy is also recommended by European, UK, and ATA guidelines (7; 8).


The thyroid gland is located on the neck and responsible for the production of T3 and T4, which are essential for normal development, growth, neural differentiation, and metabolic regulation, cf fig. A (1; 2). T4 is the primary isoform produced in the gland, whereas the active form, T3, is produced to a lesser extent. In target tissues, T4 is converted to T3 by deiodinase enzymes, a process necessary due to T3’s higher affinity for thyroid hormones receptors (4, 5).
