Iodine Synergy™

10,000 mcg Iodine with 40 mcg Selenium for Thyroid Function, Thyroid Hormone Synthesis, T4-to-T3 Conversion, and Antioxidant Status*

Key Performance Benefits*

• Supports thyroid function

• Supports thyroid hormone synthesis

• Supports normal conversion of T4 to T3

• Supports antioxidant status

What This Product Is

Iodine Synergy contains potassium iodide for supporting normal thyroid function, including balanced production of the thyroid hormones thyroxine (T4) and triiodothyronine (T3). The selenium works synergistically with iodine to support the normal conversion of T4 into T3, which helps support antioxidant status.*

Iodine is part of the structure of thyroid hormones, making this trace element essential for thyroid hormone synthesis. Selenium is a required mineral for proper functioning of the enzymes involved in T4-to-T3 conversion. A balance between selenium and iodine is required for optimal thyroid health. Some environmental pollutants such as fluoride, bromine, and perchlorate may compete with iodine uptake.*

Mechanism of Action

Potassium Iodide for Thyroid Hormone Synthesis*

10,000 mcg of iodine as potassium iodide provides essential support for thyroid hormone synthesis. Iodine is a structural component of thyroid hormones T4 and T3, which regulate metabolism, growth, and development.

Selenomethionine for T4-to-T3 Conversion*

40 mcg of selenium as selenomethionine supports the normal conversion of T4 into the active thyroid hormone T3 and helps support antioxidant status in the thyroid.

Synergistic Iodine-Selenium Balance*

The combination provides synergistic support for thyroid function, immune function, and antioxidant status while maintaining the proper balance required for optimal thyroid health.*

Athletic Applications

• Individuals seeking thyroid function and thyroid hormone synthesis support*

• Those looking for support for normal T4-to-T3 conversion*

• Individuals wanting synergistic iodine and selenium for thyroid health*

• Those seeking antioxidant and immune function support through iodine and selenium*

• Individuals with potential iodine insufficiency from dietary or environmental factors*

Frequently Asked Questions

How does Iodine Synergy compare to other DFH thyroid support products?

Iodine Synergy provides a focused two-ingredient formula of iodine and selenium specifically for thyroid hormone synthesis and T4-to-T3 conversion, offering targeted iodine support at 10,000 mcg per serving with synergistic selenium.*

Why is selenium included with iodine?

Selenium is required for proper functioning of the enzymes that convert T4 into active T3. Selenium deficiency may reduce iodine metabolism and thyroid hormone synthesis. A proper balance between both minerals is essential for optimal thyroid function.*

Who may benefit most from Iodine Synergy?

Individuals seeking support for thyroid function and thyroid hormone synthesis, those with potential iodine insufficiency, and anyone wanting synergistic iodine-selenium support for T4-to-T3 conversion and antioxidant status.*

Warning: Do not exceed the recommended dose and do not use long term without medical supervision. This product is not recommended for pregnant or lactating women.
