Iodine is required to form thyroid hormones (T3 and T4), which regulate metabolic activity in cells.
Caution: High iodine intake may be excessive for some people; monitor overall iodine from diet and supplements and consult a professional if you have thyroid concerns.
Selenium is a cofactor for iodothyronine deiodinase enzymes that convert T4 to the active hormone T3 and supports antioxidant defenses in the thyroid.
Caution: High selenium intake may cause adverse effects; consider total selenium from diet and other supplements and follow label directions.
L-tyrosine provides the amino acid backbone used to build thyroid hormones and is a precursor for catecholamine neurotransmitters.
Caution: May cause jitteriness or affect sleep in some people; avoid close to bedtime and be cautious with stimulants.
Iodine supplies the essential halogen needed to build thyroid hormones, while L-tyrosine provides the amino acid scaffold for hormone structure. Selenium supports the enzyme-driven conversion of T4 to T3 and helps protect the thyroid from oxidative stress, complementing iodine and tyrosine roles.
Label Warning: Do not use if trying to conceive, pregnant, or nursing.
Who should be cautious: People with thyroid conditions or on thyroid medications may need to monitor iodine and selenium intake. Those with iodine sensitivity or on medications affected by minerals should discuss use with a healthcare provider before starting.

lodine including potassium iodide, sodium iodide, and molecular iodine for thyroid hormone synthesis, which in turn supports a healthy metabolism, lustrous hair, and healthy hormone balance.††
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.
