Selenium, although present in microscopic amounts in nature, is a very important element that ensures the proper functioning of the human body. Among other things, it affects the functioning of the thyroid gland and the immune system. Interestingly, it can also lower the risk of developing certain types of cancer. What is selenium found in and when are its deficiencies?

Selenium – properties

Selenium was discovered in 1817 by the Swedish chemist JJ Berzelius, but because it is present in microscopic amounts in nature, it was not the subject of any particular research until the beginning of the XNUMXth century, when, thanks to the development of technology, it was possible to thoroughly examine the properties of selenium or subject it to research other micronutrients.

Selenium plays an important role in the body. First of all, it is needed for the proper functioning of enzymes, protecting cells against free radicals or toxins. Selenium is also necessary for the proper functioning of the thyroid gland, and even supports the treatment of pain in rheumatoid arthritis, or it is administered in the treatment of depression, although in excess it can cause symptoms of depression and diseases of the nervous system.

Selenium – the demand

The daily requirement for selenium in the body is 55 µg for men and 55 µg for women. In pregnant and breastfeeding women, the demand for selenium increases to 70 µg, while in children the dose depends on the age. Infants need 15-20 µg, children between 1 and 3 years old – 20 µg, children from 4 to 9 years old – 30 µg, children from 10 to 12 years old – 40 µg, and children from 13 years old – 55 ug.

The daily selenium requirement helps to provide adequate supplementation. For children, we recommend Virikid – vitamins and minerals for children Viridian, which contains, among others 24 μg of selenium and many other valuable vitamins and minerals.

At medonetmarket.pl you can buy OPC Synergia, a selenium dietary supplement. The preparation is rich in antioxidants obtained from red grapes, pine bark, green tea and vitamin E. Thanks to the mixture of natural ingredients, OPC Synergy helps to strengthen the heart, lowers cholesterol and has a positive effect on the overall condition of the body.

Selenium is one of the minerals found in the Puritan’s Pride dietary supplement available on Medonet Market. You can also try Selen SOLHERBS, which has a natural composition and can be used by vegans and vegetarians, and has ecological packaging.

Selenium – a powerful antioxidant

Antioxidants are compounds that prevent damage to our body’s cells. These damages are caused by the action of free radicals, which are natural byproducts of processes in the human body, including metabolism. Free radicals are essential for our health, but certain factors (smoking, alcohol consumption, stress) can cause an excess of them in the body, which in turn causes oxidative stress that destroys healthy cells.

Oxidative stress is closely related to the emergence of diseases such as:

heart diseases,
Alzheimer’s disease,
tumors,
stroke.

It also shows a strong relationship with premature aging of the body.

Antioxidants such as selenium help reduce oxidative stress by controlling the number of free radicals. They even neutralize their excess and have a protective function.

We recommend Clear Skin Complex Viridian if you want to provide your body with selenium and other ingredients that have a positive effect on the human body.

Selenium – reduces the risk of some cancers

In addition to reducing oxidative stress, selenium may help reduce the risk of certain cancers. It is possible due to the fact that selenium has the properties of reducing DNA damage, strengthening the immune system and destroying cancer cells.

Research studies show that high levels of selenium in the blood are associated with a lower risk of certain types of cancer, including:

breast cancer
lung cancer
colorectal cancer,
prostate cancer.

Important!

This effect was only associated with selenium obtained from food, not supplements.

Selenium – a healthy heart

A selenium-rich diet can help maintain adequate heart health. Due to the fact that it reduces inflammation in the body and oxidative stress, it protects our heart against the development of dangerous diseases, including, for example, atherosclerosis. As a result, a stroke or myocardial infarction may occur.

Including selenium-rich foods in your diet is a great way to minimize oxidative stress and inflammation.

Did you know that an ingredient in tomatoes can protect against atherosclerosis?

Selenium – choroba Alzheimera i Parkinsona

Alzheimer’s disease is a progressive neurodegenerative disease and the most common form of dementia. This disease in the United States is the sixth leading cause of death. It is believed that oxidative stress is closely related to the development and progression of Alzheimer’s disease, Parkinson’s disease and multiple sclerosis.

Research has shown that patients with Alzheimer’s disease have a lower blood selenium content. In addition, some analyzes have indicated that antioxidants in foods and supplements can improve memory in Alzheimer’s patients.

What’s more, the daily consumption of selenium-rich Brazil nuts improves verbal fluency and mental functions in patients with mild cognitive impairment. And Mediterranean diet, rich in selenium-rich foods, such as seafood and nuts, is associated with a lower risk of developing Alzheimer’s disease.

Selenium – a healthy thyroid

Selenium is a very important element that ensures the proper functioning of the thyroid gland. In fact, thyroid tissue contains more selenium than any other organ in the human body. Selenium helps protect the thyroid from oxidative damage and plays a vital role in the production of thyroid hormones.

Selenium deficiency is associated with thyroid conditions such as chronic lymphocytic thyroiditis – Hashimoto’s, a type of hypothyroidism in which the immune system attacks the thyroid gland.

The studies carried out on the influence of selenium on the functioning of the thyroid gland show that the low level of selenium in the blood serum was associated with an increased risk of autoimmune thyroiditis and hypothyroidism. Additionally, some studies have found that selenium supplements may have health benefits for people with Hashimoto’s disease.

One study found that taking selenium supplements daily for three months reduced levels of anti-thyroid antibodies. It also led to an improvement in mood and overall well-being in people with Hashimoto’s disease.

Take care of the correct level of selenium in your body with the 200ug Viridian Selenium supplement.

Selenium – effect on bronchial asthma

Asthma, also known as asthma, is a chronic inflammation of the bronchi that leads to uncontrolled contraction of the bronchi. The disease is closely related to increased levels of oxidative stress and inflammation in the body.

Due to selenium’s ability to reduce inflammation, some research suggests it may help reduce symptoms associated with asthma. For example, one study found that giving people with asthma 200 mcg of selenium per day reduced the use of corticosteroids to control symptoms. Another analysis shows that patients with asthma and higher levels of selenium in the blood had better lung function than those with lower levels.

Sources of selenium in food

Organic selenium, i.e. the one that occurs naturally in food, is best absorbed. You can use dietary supplements with selenium, but before using them, it is necessary to check the level of selenium in the body and pay attention to the components of the diet, so that selenium poisoning does not occur by taking too high doses. If selenium is needed by your body, try Ultimate Beauty Complex Viridian – a supplement that combines various minerals that together favorably affect the hair and skin.

Organic selenium is found primarily in Brazil nuts, salmon and tuna. Interestingly, only 100 g of tuna covers an adult’s daily selenium requirement of 95 percent. In addition, selenium can be found in beef, turkey fillet and eggs. It is also found in rice, although in much smaller amounts than in meat.

Although selenium is essential for optimal health, an excess of selenium can be dangerous to our body. In fact, consuming high doses of selenium can be toxic and even fatal.

Although selenium toxicity is rare, it is important to stay near the recommended dose of 55 mcg per day and never exceed the allowable upper limit of 400 mcg per day.

Brazil nuts contain a very large amount of selenium. Consuming too much of them can lead to selenium toxicity. However, toxicity is more likely to come from taking supplements than from eating selenium products.

Signs of selenium toxicity include:

hair loss,
dizziness,
nausea,
vomiting,
flushing of the face
trembling,
muscle pain.

In severe cases, acute selenium toxicity can lead to severe intestinal and neurological symptoms, heart attack, kidney failure and even death.
