Our Food-Grown® Selenium Plus has been expertly formulated to support normal immunity, thyroid health and healthy sperm development. Vitamin E has been included in our formulation to protect our body cells from oxidative damage. Oxidative damage has been associated with many health conditions and premature ageing. Our Food-Grown® Selenium has been shown to be 22% better absorbed and retained than many other forms of the mineral. Research shows food sources are declining due to poor soil content.
