Selenium, an essential antioxidant micronutrient, plays crucial roles in reducing oxidative stress, managing inflammation, bolstering immune function, ensuring cardiovascular health, and supporting the production of T3 thyroid hormone and glutathione metabolism.
A deficiency in selenium can lead to various health issues, including heart disease, cancer, cognitive dysfunction, selenoprotein dysfunction, and other disorders. On the other hand, an excess of selenium may cause symptoms of selenium toxicity, such as dermatitis, alopecia, dyslipidemia, and brittle hair and nails.
Targeted selenium supplementation, particularly with selenomethionine, can help maintain optimal selenium levels, benefitting systems such as the thyroid, where it is concentrated, and antioxidant systems throughout the body. However, it's important to maintain balanced selenium levels as both its deficiency and excess can have significant health implications.
