Daily Target:

Selenium is a trace mineral that acts as a powerful antioxidant, protecting your cells from daily stressors. It's also essential for a healthy immune response and helps regulate the hormones that manage your body's metabolism. While it's found in foods like fish, meat, and eggs, the most remarkable source is the Brazil nut. In fact, a couple of Brazil nuts can often contain more than your entire daily requirement, making them of nature's most potent nutritional packages.
