Thyrocsin: A Non-Glandular Formula for Comprehensive Thyroid Support*

Thorne’s Thyrocsin is a scientifically-formulated, non-glandular supplement that provides a comprehensive blend of essential nutrients and botanical extracts to support healthy thyroid function. This formula offers the key building blocks for thyroid hormone production, aids in the conversion of T4 to the more active T3 hormone, and provides antioxidant protection for the thyroid gland. It is an ideal foundational choice for individuals seeking to nutritionally support a healthy metabolism, energy levels, and overall endocrine wellness without the use of glandular extracts.*

How It Works: A Multi-Faceted Approach to Thyroid Wellness

Thyrocsin works by providing a synergistic mix of ingredients that support every stage of thyroid hormone production and function, while also addressing the impact of stress on the thyroid.*

Foundational Nutrients for Hormone Synthesis
The thyroid gland requires specific nutrients to produce its hormones. This formula provides an optimal dose of Iodine and the amino acid L-Tyrosine, which are the fundamental building blocks of the thyroid hormones T4 and T3. These are supported by essential minerals like Zinc, Selenium, and Copper, which act as crucial cofactors in the enzymatic processes of hormone synthesis. Selenium is particularly important for supporting the conversion of the inactive T4 hormone into the active T3 hormone throughout the body.*

Adaptogenic and Antioxidant Support
To address the connection between stress and thyroid health, Thyrocsin includes the premier adaptogen Ashwagandha (as KSM-66®). This well-researched botanical helps to moderate the body’s stress response and supports a balanced cortisol rhythm, which can otherwise interfere with thyroid function. Potent antioxidants like Vitamins C and E are also included to help protect the thyroid gland from oxidative stress, a key factor in maintaining its long-term health.*
