Iodine provides the essential iodide needed by the thyroid to form the hormones T4 and T3, which regulate metabolic activity throughout the body.
Caution: Very high iodine intake may be unsuitable for people sensitive to iodine or with thyroid concerns; monitor for intolerance and consider discussing use if on thyroid medication.
L-tyrosine supplies the amino acid backbone that combines with iodine to form thyroxine (T4), supporting normal thyroid hormone production.
Caution: May be stimulating for some people; avoid taking close to bedtime and use caution with thyroid medications or MAO inhibitors due to potential interactions.
Selenium-dependent enzymes help convert T4 into the active hormone T3 and support antioxidant defences within thyroid tissue.
Caution: High selenium intake may cause stomach upset or brittle hair and nails in sensitive individuals; avoid combining with other high-dose selenium supplements.
Iodine provides the iodide required to build thyroid hormones, while L-tyrosine supplies the amino acid backbone for T4 and T3 formation. Selenium supports the enzymatic conversion of T4 to T3 and helps protect thyroid cells from oxidative stress.
Label Warning: Do not use if trying to conceive, pregnant, or breastfeeding.
Who should be cautious: Contains high-dose iodine and selenium. People with thyroid conditions, on thyroid medications, or with iodine sensitivity may need caution. Those with kidney concerns or on medications affected by minerals may also wish to discuss with a healthcare provider before use.

L-tyrosine, an amino acid required to create the thyroid hormone thyroxine, supports mental well-being and daily energy.
Selenium is a key mineral that supports the conversion of T4 into the active thyroid hormone, T3. It works with iodine and L-tyrosine to protect the thyroid from the risk of oxidative stress and damage.
Selenium may reduce the risk of certain cancers. Some scientific evidence suggests that consumption of selenium may reduce the risk of certain forms of cancer.
