Infographic on selenium deficiency and selenium's antioxidant and thyroid role, featuring Stoneblood Shilajit Magic Brown.

Selenium is a powerful trace mineral essential for antioxidant defense, immune function, thyroid health, and DNA protection. It plays a vital role in more than 25 selenoproteins that help keep your body balanced and resilient — working alongside vitamin E and other antioxidants to protect cells from oxidative stress.

Signs your selenium intake may be low

Commonly discussed signs of low selenium include fatigue, a weakened immune response, thyroid imbalance, muscle weakness, hair loss or brittle nails, frequent illness or slow recovery, brain fog, and mood changes. These are general signals — persistent or serious symptoms warrant a conversation with a healthcare provider.
