Selenium is a trace mineral that plays a crucial role in maintaining good health. Although required in small amounts, selenium offers several significant benefits to the human body. According to Healthline and WebMD, here are the key health benefits of selenium.
Powerful Antioxidant:
Selenium acts as a potent antioxidant, protecting the body against damage caused by harmful free radicals. It works in conjunction with other antioxidants, such as vitamin C and vitamin E, to neutralize these free radicals and reduce oxidative stress. By doing so, selenium helps to lower the risk of chronic diseases, including heart disease, certain cancers, and neurodegenerative disorders.
Thyroid Function:
Selenium is essential for the proper functioning of the thyroid gland. It plays a vital role in the conversion of the thyroid hormone thyroxine (T4) into its active form, triiodothyronine (T3). This conversion is crucial for maintaining a healthy metabolism, regulating body temperature, and supporting normal growth and development. Adequate selenium levels help ensure optimal thyroid function.
Immune System Support:
Selenium is known to enhance immune system function. It stimulates the production of immune cells and promotes the activity of natural killer cells and T-cells, which are vital for immune response and defence against infections. Selenium also helps in reducing inflammation in the body, supporting overall immune health.
Cognitive Health:
Selenium has been linked to cognitive function and may play a role in maintaining brain health. Studies have suggested that selenium may help protect against cognitive decline and neurodegenerative disorders such as Alzheimer’s and Parkinson’s disease. It is believed that the antioxidant properties of selenium contribute to these benefits.
Reproductive Health:
Selenium is important for both male and female reproductive health. In men, selenium is involved in the production of the sperm and helps maintain healthy sperm motility. In women, selenium aids in the proper functioning of the ovaries and supports fertility.
While selenium is essential for good health, it’s important to note that excessive intake can have adverse effects. The recommended daily intake for adults is around 55 micrograms, and most individuals can meet their selenium needs through a balanced diet. Good dietary sources of selenium include Brazil nuts, seafood, poultry, eggs, and whole grains.
Selenium is a vital trace mineral that offers numerous health benefits. From its antioxidant properties to supporting thyroid function, immune system health, cognitive health, and reproductive health, selenium plays a crucial role in overall well-being. As always, it’s best to consult with a healthcare professional or a registered dietitian before making any significant changes to your diet or supplementation routine.
