Selenium Deficiency: The Silent Threat to Your Health

Selenium is a trace mineral essential for numerous bodily functions. Even a slight deficiency can cascade into serious health issues, affecting everything from your immune system to your thyroid function. It plays a pivotal role in protecting cells from oxidative damage. As an antioxidant, it works alongside vitamin E to neutralize free radicals. Populations with low selenium intake face higher risks of heart disease, weakened immunity, and even certain cancers. The thyroid gland relies heavily on selenium for hormone production; deficiency leads to fatigue, weight gain, and depression. Diet is the primary source, found in Brazil nuts, seafood, and eggs. The recommended daily intake is 55 micrograms for adults.
