Enhance the conversion of T4 into the active thyroid T3


Thyrotain includes a multidimensional blend of nutrients and botanicals to help maintain healthy thyroid function.  


$40 Thyrotain | Maintain Healthy Thyroid Function

  • Helps to Maintain Healthy Thyroid Function
  • Promotes the Synthesis of Thyroid Hormones
  • Helps Support Conversion of T4 to T3
  • Improves Cellular Sensitivity to Thyroid Hormones


Thyrotain is a comprehensive formulation that provides a blend of  nutrients and botanicals working in synergy to support thyroid health.  Thyrotain includes L-tyrosine and iodine, which make up the backbone of  the thyroid hormones thyroxine (T4) and triiodothyronine (T3). The  addition of zinc, selenium, vitamin A, and the botanical guggulipid  activate enzymes that enhance the conversion of T4 into the active  thyroid hormone T3. Vitamin A and zinc also help improve cellular  sensitivity to thyroid hormones. Turmeric, along with the antioxidants  vitamin C and E and N-acetyl cysteine (NAC), provide a powerful  combination of antioxidants that boost thyroid health by reducing free  radical stress. 

The thyroid gland, located in the neck below the Adam’s apple, produces T4 and T3 hormones that regulate cell metabolism. In  this  process,  thyroxine  is  converted  into  the  metabolically  active   hormone   T3.   Thyroid   hormones   are   required   for   mitochondrial metabolism in every cell in the body. Therefore, a deficiency of thyroid hormones can affect virtually all bodily functions,  including  metabolic  rate,      reproduction,  hormone  production,  and  brain  function,  as  well  as  musculoskeletal,  psychological and cardiovascular health.1Lifestyle factors, environmental toxins and nutrient deficiencies can negatively impact thyroid hormone production. A number of nutrients are required to produce thyroid hormones and tohelp  convert  T4  into  T3.  These  nutrients  include  L-tyrosine,  iodine,  selenium,  zinc  and  vitamin  A.  A  deficiency  in  any  of  these nutrients can cause the thyroid to under-function. Heavy metals,  such  as  mercury,  lead  and  cadmium,  as  well  as  other  chemical  contaminants,  can  also  block  the  conversion  of  T4  to  T3.  In  addition,  long-term  stress  can  lead  to  increased  production  of  the  adrenal  hormone  cortisol.  Excessive  levels  of  cortisol  can  block  the  conversion  of  T4  to  T3  and  also  increase the production of reverse T3 (RT3). RT3 is an isomer of triiodothyronine  that  competes  with  T3  at  the  receptor  sites.  Conversely,  exercise  positively  impacts  the  thyroid  gland  by  stimulating hormone secretion and increasing tissue sensitivity to thyroid hormones. 


Vitamins and Minerals

Thyroid hormones are made from amino acid L-tyrosine and iodine. Iodine  is an essential trace mineral and is necessary for the synthesis of  thyroid hormones, as it is one of the most important components of the  hormones T4 and T3. The thyroid gland absorbs iodine from the blood and  incorporates it into thyroid hormones. In addition to supporting thyroid  hormone production, research shows iodine acts as an antioxidant,  supporting a healthy thyroid gland and protecting a variety of tissues,  including mammary tissue, the eyes and gastrointestinal lining.

Normal thyroid status is dependent on adequate levels of many trace  minerals for the synthesis and metabolism of thyroid hormones. The  minerals zinc and selenium are required cofactors for the enzymes that  convert T4 to T3. Selenium deficiency has been shown to contribute to  decreased T4 to T3 conversion. Supplementation of selenium can also help  decrease thyroperoxidase (TPO) antibodies in thyroid autoimmunity.  Supplementation with zinc has been shown to restore T3 levels in  patients with normal T4 and low T3, demonstrating its role in the  conversion process. Vitamin A and vitamin E are also necessary for  normal thyroid hormone manufacturing.

Antioxidants (Turmeric, Vitamins C and E, and N-Acetyl Cysteine)

Ashwagandha (Withania somnifera) has been used in Aryuvedic and  indigenous medical systems for over 3,000 years and has been examined  in research studies for its stress-lowering effects. Ashwagandha has  been found to exhibit GABA agonist activity, which accounts for its  ability to relax the nervous system. Ashwagandha may also stimulate  thyroid activity indirectly, via its effects on cellular antioxidant  systems, specifically by increasing the antioxidant enzymes superoxide  dismutase and catalase and reducing lipid peroxidation. 


The gum resin of the guggul plant has been used in Ayurvedic medicine in India for nearly 3,000 years. Guggulipid (Commiphora mukul)  has been shown to support thyroid function, primarily by decreasing  lipid peroxidation in the liver, the principal site of T3 generation.  Guggul extract has also been shown to have thyroid-stimulating action by  increasing iodine uptake by the thyroid gland and increasing the  activities of thyroid peroxidase and protease.
