Along with Iodine, the amino acid L-Tyrosine is essential to the production of thyroid hormones. Research suggests that supplementing with L-Tyrosine can help support healthy thyroid and adrenal function.*

Green Tea

Green Tea (Camellia sinensis) contains a variety of chemical constituents that can support relief from fatigue and help to ease stress. Research suggests that the amino acid L-Theanine, found within Green Tea, can be effective for regulating the system and in turn, help to support healthy thyroid function.*


Commiphora mukul is a fragrant resin that is commonly referred to as Myrrh and its Ayurvedic name Guggul. Gugulipid® is a premium standardized extract that contains concentrated bioactive compounds unique to Guggul, such as guggulsterone. Guggul has been studied for its effect on cholesterol synthesis in the Liver and research suggests that it can improve thyroid hormone production.*


Bacopa monniera is recognized by Ayurvedic physicians for its cognitive support as well as an overall vitality tonic. Bacopin® is a premium concentrated extract that contains bioactive compounds unique to Bacopa, such as bacosides. Research suggests that Bacopa can stimulate thyroid gland function by helping to concentrate thyroid hormones.*


The root of the botanical Withania somnifera is more commonly known by its Ayurvedic name, Ashwagandha and is considered an adaptogen that helps to balance the overall system. Ashwagandha has been studied for its effect on regulating stress hormones and research suggests that it can have a normalizing effect on thyroid and adrenal function.*
