Selenium Benefits: 10 Selenium Storage Nutrients

You may not know, but your body needs selenium. Like all trace minerals, it is essential for the proper functioning of the body. However, selenium is needed at lower levels than vitamins and minerals that are required by the body in large amounts, such as calcium and iron. Therefore, it is called a micronutrient.
What is Selenium?
Selenium was discovered as an element in 1817 by Swedish chemist Jöns Jacob Berzelius, who determined the atomic weights of many elements and developed the system of chemical symbols. It was first thought to be a toxin; However, scientists later determined that selenium was an essential mineral in the 1950s.
Selenium is a trace mineral that occurs naturally in soil and certain foods, and is even found in small amounts in water. It is an extremely important mineral for the human body as it increases immunity, is involved in antioxidant activity that prevents free radical damage and inflammation, and plays a key role in maintaining a healthy metabolism.

What are the Benefits of Selenium ?
- May Help Fight Cancer: Selenium is especially helpful if you have a weak immune system or a family history of cancer. According to studies, selenium; It is effective in reducing the risk of cancer incidence, cancer-related mortality (death rate) and the severity of cancer cells (especially in the liver, prostate, colorectal and lungs).
- Strengthens the Immune System: According to studies, selenium is necessary for the proper functioning of the immune system and may also be an important building block in preventing the development of viruses, including HIV. It has been understood that selenium is useful in slowing down the progression of the disease and AIDS in patients with HIV virus.
- Increases Blood Flow and Lowers the Risk of Heart Disease: Selenium supplements or increasing consumption of selenium-rich foods may help prevent coronary heart disease. Selenium; It is believed that it may benefit heart health with its ability to fight inflammation, increase blood flow, reduce free radical oxidative stress, and aid antioxidant activity. However, observational studies can occasionally lead to misleading evidence, and so findings are still inconclusive as to whether selenium should generally be prescribed for prospective heart patients.
- Helps Reduce Asthma Symptoms: Observational studies have found that patients with chronic asthma have lower selenium levels. According to studies, when people with asthma took selenium supplements, they experienced fewer asthma-related symptoms than those who took a placebo. Experts think that selenium supplementation may be a useful adjunct treatment to medication for patients with chronic asthma.
- May Help Increase Fertility: Selenium is essential for proper sperm motility. Selenium is incorporated into the sperm mitochondria capsule and may affect the behavior and function of sperm as they move through the vaginal canal. Some studies also show that selenium may reduce the risk of miscarriage, but at this point, more research has been done on men than on women when it comes to selenium supplementation.
- Regulates Thyroid Function: Selenium acts as a catalyst for the production of thyroid hormones. The thyroid gland controls many important daily body functions, including appetite, sleep, temperature, weight, energy and more. A problem with thyroid function; It can result in negative symptoms such as irritability, muscle weakness, fatigue, weight gain or weight loss, and insomnia. Therefore, you can benefit from its effects by taking appropriate amounts of selenium into the body.
- Defends the Body Against Oxidative Stress: Selenium’s properties include its ability to combat the aging process and aid the immune system by reducing free radical damage. Selenium has a synergistic effect with other antioxidants such as vitamin E, enabling the body to fight oxidative stress and defend against cancers such as prostate and colon cancer. Selenium is an essential component of glutathione peroxidase, an enzyme important for processes that protect lipids (fats) in cell membranes. Selenium is essential for fighting oxidative degradation of cells and protecting against mutation and DNA damage that can cause disease.

Selenium Deficiency Symptoms, How to Understand?
Selenium is an important mineral; because it supports the function of various systems. These are the endocrine, immune and cardiovascular systems. A 2011 review suggests there may be a link between selenium deficiency and certain types of cancer.
The most common symptoms of selenium deficiency are:
- Infertility in men and women

Additionally, selenium levels decrease with age. Therefore, it is thought that selenium may slow the aging process, cognitive decline, and dementia.

What are the Side Effects of Selenium?

Excessive dose of selenium in the body; It can cause reactions such as bad breath, fever, nausea, and potentially liver complications (even kidney and heart problems). However, these only occur at very high selenium levels that reach a “poisoning” state.
