Selenium (Bld)
Selenium is a trace mineral that powers up thyroid function, antioxidant defense, and immune resilience. It helps convert T4 into active T3, and protects your cells from oxidative stress — especially in the brain, thyroid, and reproductive system. Even small deficiencies can impact energy, mood, fertility, and inflammation levels. But too much? That can backfire too — think of selenium like a precision tool, not a blunt instrument.
