Hypothyroidism —also known as an underactive thyroid—is a common metabolic disorder that primarily affects women between the ages of 35 and 65. It occurs when the thyroid gland produces too few hormones. This affects many bodily systems—such as energy metabolism, circulation, mental health, hair, and skin—because thyroid hormones are involved in numerous processes in the body. As a result, hypothyroidism can cause symptoms such as fatigue, weight gain, sensitivity to cold, hair loss, or a lack of energy.
Iodine is a key trace element for thyroid health. Without iodine, the body cannot produce thyroid hormones. Therefore, ensuring an adequate intake of iodine is important for people with hypothyroidism—though in certain cases, the need for iodine may be higher and thus varies from person to person. In this article, you’ll learn about the role iodine plays in thyroid function, which foods are rich in iodine—and when it may be beneficial to take iodine supplements.
How does iodine support thyroid function?
Iodine is an essential component for the production of the thyroid hormones thyroxine (T4) and triiodothyronine (T3). These hormones regulate numerous bodily processes—such as energy metabolism, body temperature, and mental performance. However, if an iodine deficiency occurs, the thyroid gland is no longer able to produce enough T3 and T4, which ultimately—if left untreated—leads to an underactive thyroid (hypothyroidism).
In addition to the rather nonspecific symptoms mentioned above, an enlarged thyroid gland can lead to the formation of a goiter (struma). Along with other causes, this can be a clearly visible sign of iodine deficiency.
Many functional physical complaints, such as circulatory problems, anxiety disorders, or muscle tension, can also be attributed to an insufficient intake of iodine. Studies show that an adequate intake of iodine can alleviate the symptoms of hypothyroidism.
What role does iodine play in the treatment of hypothyroidism?
Not every case of an underactive thyroid (hypothyroidism) is caused by an iodine deficiency—but in many cases, iodine plays a crucial role. Targeted iodine supplementation can then help restore balance to thyroid function.
In certain life situations—such as when nutritional needs are higher or dietary options are limited—targeted dietary supplementation may be beneficial.
According to the DGE and the WHO, the recommended daily intake for adults is200 micrograms of iodine. This amount can easily be obtained from iodine-rich foods such as saltwater fish, seafood, dairy products, and eggs. Another sensible measure is to use iodized table salt when preparing meals each day.
A natural supplement like our Pro Jod provides high-quality iodine derived from seaweed and gently supports thyroid function—ideal for anyone who wants to strengthen their thyroid in a reliable and holistic way.
Foods Containing Iodine: These Sources Are Especially Valuable
In many regions of Europe—including Germany—the soil is naturally low in iodine. As a result, locally grown produce such as fruits, vegetables, and grains contain only small amounts of iodine. This makes it all the more important to specifically choose foods that are naturally rich in iodine—and thus help support thyroid function.
Sea fish such as cod, pollock, and herring are especially recommended. Seafood such as shrimp and mussels also provide significant amounts of iodine. In addition, dairy products and eggs contribute to iodine intake—they’re simple and easy to incorporate into your daily routine. Those who eat a varied diet and regularly include these natural sources of iodine are already laying a solid foundation for a healthy thyroid.

How can Pro Jod help support thyroid function?
Sometimes, iodine intake from diet alone is not sufficient—for example, in cases of an iodine-deficient diet or when there is an increased need, as is the case with pregnant women, breastfeeding women, athletes, and adolescents. In such cases, targeted dietary supplementation can effectively support iodine balance.
Our Pro Jod contains valuable natural iodine from North Atlantic knotted kelp (Seagreens® Ascophyllum nodosum) —a seaweed known for its high purity and sustainable sourcing. The formula is supplemented with high-quality astaxanthin from Haematococcus pluvialis —a powerful antioxidant that can protect cells from oxidative stress.
This combination not only supports the thyroid gland, but also—for example—the nervous system, concentration, and energy metabolism. Pro Jod meets the recommended daily intake of iodine—so you’re well-nourished in every way in your daily life.
Conclusion: Take targeted iodine supplements—for a healthy thyroid and more energy
Iodine is a key trace element for the thyroid gland—and much more than that. It contributes to the production of vital hormones that primarily support metabolism, the nervous system, and mental performance. Especially in cases of an underactive thyroid (hypothyroidism), it’s worth taking a closer look at your iodine intake: If you have a deficiency, targeted supplementation can help restore hormonal balance and boost your energy levels.
Our high-quality Pro Jod offers a great way to reliably meet your daily iodine needs—with natural marine ingredients and a carefully formulated combination of iodine and astaxanthin. Whether for daily intake or when needs are higher: Anyone looking to support their thyroid holistically will find Pro Jod to be an effective, nature-based supplement for greater well-being in everyday life.
