Boost Immune Function

Oysters may include vitamins and minerals that are important for your immune system. It may be high in zinc and selenium, which may be important in supporting a healthy immune system. While selenium is an excellent antioxidant, zinc aids in the fight against infections.

Aside from essential vitamins like vitamin C and D, oysters can be high in vitamin B12, which is essential for immune system health. They contain zinc, which appears to have virus-fighting properties. This is most likely due to zinc's role in the formation and activation of white blood cells involved in the immunological response. It also helps your immune system with duties like wound repair.
