Despite being a fundamental micronutrient, selenium is often unheard of, and many people are unaware of its importance for the body. As a result, an estimated 0.5 to 1 billion people worldwide suffer from selenium deficiency.
Selenium, a potent antioxidant, is necessary for the proper functioning of the immune system; thus, inadequate levels can increase the likelihood of illness. It also assists in DNA synthesis and helps maintain a healthy metabolism.
Selenium is a trace mineral naturally found in the soil and can be found in water and certain foods. It is classified as a micronutrient since the body requires less of it compared to other essential vitamins and minerals. In addition to strengthening the immune system, selenium facilitates “metabolic processes, reproduction, DNA synthesis, and thyroid function.”
In addition to its numerous benefits, selenium possesses powerful antioxidant properties that can help prevent cell damage that may lead to cancer. These antioxidant properties can also aid in reducing the risk of cognitive decline as a person ages. Some studies have found selenium to be beneficial in preserving thyroid function, especially in women, preventing the progression of HIV to AIDS, reducing the risk of miscarriage, and alleviating asthma symptoms.
