Selenium deficiency: The 10 most important symptoms – and how you can protect yourself

Selenium is an essential trace element that plays a central role in our body. Although only small amounts are needed, it has far-reaching effects on health. Selenium acts as an antioxidant, supports the immune system, promotes thyroid function and is essential for many other physiological processes. A selenium deficiency can therefore cause serious health problems, which manifest themselves in a variety of symptoms.
In this article, we would like to highlight the ten most common signs of selenium deficiency and explain how you can avoid a deficiency.

What is selenium and why is it important?
Selenium is one of the trace elements that the body cannot produce itself. It must therefore be obtained through food. Good sources of selenium include Brazil nuts, fish, eggs, whole grains and meat. The body needs selenium for the production of selenoproteins, which act as antioxidants and protect cells from damage caused by free radicals. This protective function is essential for strengthening the immune system, reducing inflammation and preventing chronic diseases.

Causes of selenium deficiency
Selenium deficiency often occurs in regions where the soil has a low selenium content, such as in Europe, Asia and Africa. Other causes include an unbalanced diet, certain chronic diseases such as Crohn's disease or coeliac disease, and limited nutrient absorption.

The 10 most important symptoms of selenium deficiency

1. Weak immune system
Insufficient selenium levels can impair immune function, leading to increased susceptibility to infections. Colds and flu-like infections occur more frequently and last longer.

2. Fatigue and exhaustion
If you feel constantly tired and exhausted, selenium deficiency could be the cause. Selenium plays an important role in energy metabolism, so a deficiency can lead to general weakness.

3. Muscle pain and weakness
Selenium deficiency can impair muscle function, which can manifest itself in pain, weakness or even cramps.

4. Hair loss
A noticeable sign of selenium deficiency is increased hair loss. At the same time, the hair can become brittle and lose its shine.

5. Cognitive impairment
Memory problems, difficulty concentrating and general "mental sluggishness" can indicate selenium deficiency. Selenium is important for proper brain function and the protection of nerve cells.

6. Cardiovascular problems
Selenium deficiency is also associated with cardiomyopathies, i.e. diseases of the heart muscle. In the long term, cardiovascular diseases can be promoted.

7. Thyroid problems
The thyroid gland needs selenium for the production and regulation of hormones. A deficiency can lead to an underactive thyroid (hypothyroidism), which causes symptoms such as weight gain, sensitivity to cold and fatigue.

8. Fertility problems
In men, selenium deficiency can impair sperm quality, which can lead to fertility problems. Women may also experience difficulties conceiving, as selenium supports hormone regulation.

9. Increased susceptibility to oxidative stress
Oxidative stress occurs when free radicals attack cells and antioxidants such as selenium are lacking to neutralise these free radicals. This can lead to faster cell ageing and an increased risk of chronic diseases.

10. Delayed wound healing
Insufficient selenium intake can impair wound healing, as selenium plays an important role in cell regeneration and inflammation inhibition.

A gentle way to support: SELENIUM | PUR capsules
If you want to specifically support your selenium levels, supplements such as SELENIUM | PUR capsules are a useful addition. These capsules contain high-quality sodium selenite, a highly bioavailable form of selenium, as well as calcium carbonate, which also contributes to general health. They offer a convenient way to provide your body with the optimal amount of selenium.

Conclusion
A selenium deficiency can manifest itself in a variety of symptoms that are often non-specific and easily overlooked. The effects range from chronic fatigue to heart problems. It is therefore important to ensure an adequate intake of this trace element in order to protect your health.
