What you certainly did not know about iodine
A surprising statement about the underrated trace element iodine .
Author: Kyra Kauffmann, non-medical practitioner
As a child I used to pull my nets through the undergrowth in our area and looked for tadpoles in the ponds. I loved these tiny, lively larvae that turned into frogs or toads after a few weeks. Like then I am still fascinated today.
What I did not know at the time was that tadpoles need iodine-rich water for this metamorphosis to take place. Only tiny amounts of this trace element are sufficient, but if they are missing, the development to the frog is omitted.
Today we roam through nature with our sons - tadpoles and frogs - forty years ago at home everywhere - are unfortunately a rarity today.
For the metamorphosis of the frog, iodine is essential - and for us humans?
To understand the importance of iodine in our health , it's worth taking a quick look at human evolutionary biology.
No researcher knows so much about iodine and human evolution as the Italian doctor. Sebastiano Venturi. We talked to him:
Professor Venturi, you have researched iodine and thyroid hormones for many decades. Through your work, we now know a great deal more about the role that iodine has played in the evolution of vertebrates, and therefore humans as well. Please tell us a bit about your findings. What role did iodine play in evolution?
The element iodine is very interesting and played a crucial role in evolution. We found out that iodine was the first inorganic antioxidant in the cell. Antioxidants are very important to protect the cell from free radicals that constantly accumulate in the cell. In particular, the cell membranes, which consist of polyunsaturated fatty acids, are very susceptible to damage by free oxygen radicals.
Iodine was the first element that could protect early cell formations, especially cell membranes. Research has shown that 500 million years ago, the first primitive intestinal cells of the vertebrate animals developed the first primitive thyroid cells through the uptake and storage of iodine.
In parallel, under the "protective coat" of iodine and fatty acids - we call them also iodolipids - undifferentiated cells have developed into nerve and brain cells, which was another way of adapting to the environment. In this way, iodine also indirectly supported the developmental stage of life from water to land.
Iodine lipids occur in the thyroid gland as well as in the central nervous system and in the mammary gland. We can rightly say that iodine was crucial to human evolution. Without iodine, evolution would not have been possible, neither the development of the vertebrates nor the development of the brain in humans. It is a fact that for the expansion and evolution of the human brain in particular, iodine and fatty acids were the crucial elements.

So, iodine has played a prominent role in human evolution. Thanks to numerous researches, we now know that many of their body cells have their own small iodine transport locks on their membranes, with which they pump iodine into the cell (so-called sodium iodide symporter).
These locks are similar to those of algae, which trap the iodine from the seawater and store it inside. By the way, algae are the highest iodine content of all living things and foods.
The following organ cells have their own iodide symporter
What role does iodine play in human metamorphosis?
Iodine is of immense importance to us from the first second of our existence. For in the first six weeks of our existence, the central nervous system is formed - at a time when many women do not yet know that they are pregnant.
Our "larval stage" does not last four but 40 weeks and takes place within the womb. Our pond is the amniotic fluid. During this time, the fetus relies on the supply of nutrients by the maternal organism. If the mother ingests iodine (and of course other nutrients) through the diet, the fetus is first supplied with iodine via the bloodstream or later via the placenta.
"Iodine deficiency is the world's most prevalent, yet easily preventable, cause of brain damage" (World Health Organization)
What extreme (!) Causes iodine deficiency in pregnancy , shows the now extinct in Europe disease of cretinism: mental retardation and severe physical deformity with and without goiter. And that only because a trace element in the first 9 months of life was missing! These damage caused by iodine deficiency can not be repaired once the child is born.
As I said, cretinism is extinct in Europe. World-wide, however, iodine deficiency is still considered the main cause of congenital nonsense, and the WHO is trying to raise the supply of iodine to at least a minimum standard through elaborate programs in Asia and Africa.
A latent iodine deficiency in pregnancy also has massive effects on the function of the thyroid gland and the development of cognitive function of the central nervous system and may be associated with an IQ loss of up to 13 points. Iodine deficiency has proven to be stupid!
But iodine can do even more: it can protect the neonate's brain from the negative effects of toxic substances to which every mother is unfortunately inevitably exposed.
So it is enough - as many doctors advise pregnant women - to take 150 mcg of iodine daily?
No, according to the intake recommendations of the German Nutrition Society, pregnant women should administer at least 200 mcg of iodine daily, breastfeeding even 260 mcg. This is the basic care for the prevention of iodine deficiency-related damage to the child.
How do I get iodine?
Best with knife and fork, for example:
Wakame
fish
samphire
Even if you are not pregnant, you should be fed on iodine, as you now know that many organs rely on iodine for proper function.
Did you know that iodine has been proven to support the following in the body (according to Health Claims of the European Food Authority EFSA):
In addition, this trace element together with fatty acids seems to play an important role in the prevention and treatment of tumor diseases.
Most people - pregnant or not - do not pay attention to adequate iodine supply. You are just as unaware of how vitamin D was not an issue for many people just a few years ago.
What is a sufficient amount of iodine?
The German Nutrition Society states that one adult requires at least 200 mcg of iodine per day. This information is derived from the WHO recommendations for the prevention of thyroid disorders.
General statements about micronutrient requirements are generally difficult. The need for iodine depends on the lifestyle ( stress / intense sports), medications (hormones, "pill", certain psychotropic drugs), exposure to pollutants (smoking, toxic metals), thyroid volume, pregnancy / lactation ... just to name a few factors.
Everyone has to find out for himself how much iodine he needs. An iodine urine test, which many laboratories now offer, is helpful for this.
Fact is tadpoles need iodine, people need iodine. And every day.
Although we do not know exactly why the Neanderthals eventually died out, one hypothesis is that iodine deficiency has put an end to their evolution.

The following organ cells have their own iodide symporter
- chest
- Ovaries and fallopian tubes
- prostate
- salivary glands
- Gastrointestinal tract
- skin
- blood cells
- Parts of the brain
- and of course the thyroid , which has about 50% of the total body iodine requirement. The other half is needed by the above mentioned organs.

Best with knife and fork, for example:
- Algae - the best source of vegan iodine: There are a variety of delicious, edible algae and companies like Kulau, Algamar and Ark Naturkost ensure that they can be enjoyed in the best possible, pollutant-free and ecological quality.
- Sea vegetables, like the native Queller. If you live near the East or North Sea, you are sure to know this delicious plant, which is a treat both raw and cooked.
- Seafood and sea fish: Not everyone's thing, but these sea creatures are top suppliers of iodine. But: always pay attention to the quality (origin, sustainability).
- Beef liver: Not only an excellent source of iodine, but also a source of other important micronutrients such as Vitamin A and Zinc. Best of all once a week from the Biometzger. (In pregnancy, the consumption of liver is not recommended because of the high vitamin A content!)
Wakame
fish
samphire
Even if you are not pregnant, you should be fed on iodine, as you now know that many organs rely on iodine for proper function.
Did you know that iodine has been proven to support the following in the body (according to Health Claims of the European Food Authority EFSA):
- Contributes to a normal energy metabolism
- Contributes to a normal function of the nervous system
- Contributes to normal production of thyroid hormones and normal thyroid function
- Contributes to the maintenance of normal skin
- Contributes to normal growth of children
- Contributes to a normal cognitive function
In addition, this trace element together with fatty acids seems to play an important role in the prevention and treatment of tumor diseases.
