Our iodine complex offers an essential combination of iodine and selenium to support the thyroid, further enhanced with astaxanthin and L-tyrosine.
Located in the neck, just below the larynx, the thyroid is a small butterfly-shaped gland with great significance. It produces the thyroid hormones T3 (triiodothyronine) and T4 (thyroxine), which regulate many body functions – including metabolism, energy levels, the cardiovascular system and overall wellbeing.
Even slight fluctuations in hormone production can affect internal balance. Fatigue, exhaustion and nervousness are typical signs of thyroid imbalance. Targeted micronutrient intake can help support the thyroid in everyday life.

Why is iodine important for the thyroid?
Iodine is an essential trace element required for the production of the thyroid hormones thyroxine (T4) and triiodothyronine (T3). Iodine contributes to normal thyroid hormone production and the maintenance of normal thyroid function.
What makes ThyroidGold a well-rounded formulation?

L-tyrosine is a versatile amino acid and a key component in the production of neurotransmitters such as dopamine, adrenaline and noradrenaline. It is also crucial for the production of the thyroid hormones T3 and T4.
Selenium is an essential trace element with many biological functions. It is a component of over 25 selenoproteins involved in diverse biological processes and plays an important role in normal thyroid function.
What is the role of astaxanthin in the formula?
The astaxanthin in this product is extracted from the microalga Haematococcus pluvialis, which thrives in freshwater lakes, ponds and rivers. This microscopic alga is known for its ability to produce large quantities of this natural carotenoid under extreme conditions. Astaxanthin is a plant-based pigment with strong antioxidant properties that helps the alga protect itself from environmental stressors.
