Selenium for immune support: What do studies say?

Introduction

Selenium is an essential trace mineral responsible for many important functions in the body, including supporting the immune system. In recent years, there have been an increasing number of studies examining the potential benefits of selenium for immune support. In this article, we will take a look at current research and summarize the results of these studies.

What is Selenium?

Selenium is a trace element that occurs naturally and can be found in small amounts in soil and some foods. It is an important component of enzymes involved in various metabolic processes and plays a key role in fighting free radicals in the body.

Selenium and the immune system

The immune system is a complex network of cells, tissues and organs that protects the body from disease and infection. There is a growing body of evidence suggesting that selenium plays an important role in supporting the immune system.

Research has shown that selenium has an immunomodulatory effect, meaning it can influence the function of the immune system. Selenium has been shown to stimulate the activity of natural killer cells and other immune cells responsible for fighting infections.

Furthermore, selenium is also involved in the production of antibodies, which play an important role in recognizing and neutralizing pathogens. It also supports the formation of T cells, which play a central role in coordinating the immune response.

Selenium deficiency and immunity

Selenium deficiency can lead to impaired immune system function and increase susceptibility to infections. Studies have shown that people with low selenium levels are at higher risk of infections, including respiratory infections, flu and other viral illnesses.

For example, a study of elderly people in China who suffered from selenium deficiency found that administration of selenium supplements led to a significant reduction in infection rates. It has also been observed in HIV patients that selenium supplementation can slow disease progression by supporting the immune system.

Selenium and COVID-19

Recently, the COVID-19 pandemic has increased interest in the role of selenium in immune function. COVID-19 is a highly infectious disease that places great strain on the immune system. It has been found that people with severe cases of COVID-19 have lower selenium levels than people with mild cases.

A study from China published in the Journal of Clinical Endocrinology & Metabolism found that selenium supplementation can reduce the risk of severe COVID-19. Study participants who received selenium supplements had a significantly lower mortality rate and a shorter hospital stay compared to the control group.

However, it is important to note that this study is still preliminary and further research is needed to further investigate the effect of selenium on COVID-19. Currently, the use of selenium as a complementary immune support measure for COVID-19 patients is not recommended by most health authorities.

FAQs

Q: How much selenium should I take to boost my immunity?

A: The recommended daily intake of selenium for adult men and women is 55 micrograms per day. It is important not to exceed this amount as too much selenium can be toxic. If you have any questions about taking selenium supplements, you should consult a doctor or nutritionist.

Q: Which foods contain selenium?

A: Selenium-rich foods include Brazil nuts, eggs, meat, fish, mushrooms and whole grains. A balanced diet that includes these foods can help meet selenium needs.

Q: Can I increase my selenium intake through my diet alone?

A: In some cases, it may be difficult to meet selenium needs through diet alone. In such cases, supplementing with selenium supplements in consultation with a doctor may make sense.

Conclusion

Selenium plays an important role in supporting the immune system and fighting infections. There is a growing body of scientific evidence suggesting that adequate selenium intake can strengthen the immune system and protect against infections. However, it is important to note that supplementing with selenium supplements is not a replacement for a healthy diet and lifestyle. It is recommended that you stick to the recommended daily intake and consult a doctor if you have any questions or concerns.
