The Primary Benefit Is: Thyroid Function Support

Thyroid tissue derived from dried bovine sources can help support total thyroid function by providing natural thyroid components found in the tissue.

This formula uses dried bovine thyroid derived from New Zealand cattle and is made to high-purity standards, with parts and plant-based fillers noted as inactive ingredients. This approach follows well noted principles of tissue-based support and seeks to deliver tissue-related thyroid hormones within a controlled form.

What Does Thyroid Function Support Do?

Dried thyroid tissue provides natural thyroid hormones described in the product description as including T3 and T4, which take part in normal metabolic processes. Dr. Bastyr of Bastyr University has noted tissue-based concepts related to thyroid support in discussions about this kind of formulation.

Along with this, the product emphasises quality controls and GMP-certified production to help keep product integrity and provide consistent tissue-derived components that may support normal physiological thyroid function.

This supplement is not meant to diagnose, treat, cure, or prevent any disease.
