Thyroxine (T4) Free is one of the main thyroid hormones and is important for regulating metabolism. High or low levels of T4 Free can indicate thyroid dysfunction.

iollo markers that associate with Thyroxine (T4) Free


Thyroid hormones like T4 have significant effects on amino acid metabolism. Altered T4 levels may lead to changes in alanine and other amino acids.


Thyroid hormones regulate fatty acid oxidation. Carnitine is essential for fatty acid transport and metabolism, linking it indirectly to T4 status.


Phenylalanine is converted to tyrosine, which is then used to synthesize T4. Changes in phenylalanine availability can affect downstream T4 levels.


Taurine plays a role in thyroid hormone metabolism and has been shown to modulate T4 levels in some studies.


Tyrosine is a precursor for the synthesis of thyroid hormones including thyroxine (T4). Alterations in tyrosine levels can directly impact T4 production.
