Iodine: Essential Trace Element, Function & Sources
Updated: Sep 21
Iodine is an essential trace element that is indispensable for numerous functions in the human body. Yet insufficient iodine intake remains one of the most common nutrient deficiencies in Europe. A conscious, controlled intake – for example via iodine-rich mineral water – can make a valuable contribution to a balanced diet.
Anyone looking to specifically buy mineral water with iodine in Germany will find tested products at Gexa Plus, available across Europe.
Why iodine matters so much for the body
normal energy metabolism
normal cognitive function
normal function of the nervous system
growth and cell division in children
production of thyroid hormones
Because the body can't produce iodine on its own and can only store limited amounts, a regular intake via iodine-rich water or other sources is necessary.
Recommended daily iodine intake in Europe
These reference values are based on recommendations from the European Food Safety Authority (EFSA).
EFSA reference values (Dietary Reference Values)
Adults: 150 µg per day
Pregnant women: 200 µg per day
Breastfeeding women: 200 µg per day
Children (1–3 years): 90 µg per day
Children (4–6 years): 90–120 µg per day
Children (7–10 years): 120 µg per day
Teenagers (11–17 years): 130–150 µg per day
Some countries, such as Germany or Austria, sometimes recommend higher values (e.g. 200 µg for adults). At EU level, however, the EFSA reference value of 150 µg per day for adults applies as the reference standard.
Tolerable upper intake level (UL)
For adults, EFSA additionally defines a safe upper limit of:
600 µg iodine per day
Regularly exceeding this limit should be avoided without consulting a doctor.
Iodine-rich mineral water as a natural source
Alongside sea fish, algae or iodised table salt, iodine-rich water offers a practical way to support daily iodine intake.
Iodine-rich mineral water is especially popular with consumers who specifically want to buy mineral water with iodine in Germany. Via www.gexa-plus.com we ship our products throughout Europe.
Iodine content of our products
The figures below come from publicly available sources and are for information purposes only. They do not replace individual medical advice.
The mineral water Vincentka naturally contains iodide.
Iodine content: approx. 6–7 mg iodide per liter (≈ 6,000–7,000 µg/L)
Example calculation:
25 ml → approx. 150–175 µg iodide
50 ml → approx. 300–350 µg iodide
Even small amounts make a relevant contribution to daily iodine intake. Because of its high mineral content, Vincentka is consumed in moderate amounts.
Jodaqua is a dietary supplement and is one of the most iodine-rich mineral waters in Europe.
Iodine content: approx. 100 mg iodide per liter (= 100,000 µg/L)
Example calculation:
1 ml → approx. 100 µg iodide
1.5 ml → approx. 150 µg iodide
5 ml → approx. 500 µg iodide
Just 1–1.5 ml corresponds to the EFSA reference value for adults. Jodaqua isn't consumed like drinking water, but taken in small, controlled amounts.
Responsible use
With mineral waters that have a high iodine content, precise dosing is especially important. People with thyroid conditions or individual iodine sensitivity should seek medical advice before use.
Iodine-rich water offers a safe, measurable way to supplement the daily diet.
Conclusion
Iodine is an essential trace element for energy metabolism, thyroid function and mental performance.
High-quality iodine-rich water such as Vincentka and Jodaqua (dietary supplement) offer a targeted way to obtain iodide. Anyone who wants to specifically buy mineral water with iodine in Germany or source it across Europe will find tested quality, transparent labelling and Europe-wide shipping at Gexa Plus.
