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.
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.

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.
NatuGena ThyroidGold was developed in collaboration with experienced naturopath Kyra Kauffmann – an expert in holistic health with a special focus on iodine and micronutrients. Her research and practical experience have helped raise awareness about the role of iodine in supporting thyroid function and overall wellbeing.
