Zinc And Selenium For Immune System

The immune system plays a crucial role in protecting our bodies from harmful pathogens and keeping us healthy. Two essential minerals that are known to support and boost the immune system are zinc and selenium.

What is Zinc?

Zinc is a trace mineral that is required for numerous bodily functions, including immune system function. It is involved in the production of immune cells, such as white blood cells, which help fight off infections and diseases.

Zinc also plays a role in the production of antibodies, which are proteins that recognize and neutralize foreign invaders in the body. Additionally, zinc helps regulate the inflammatory response, which is important for maintaining a balanced immune system.

What is Selenium?

Selenium is another essential mineral that is important for immune system function. It acts as an antioxidant, helping to protect cells from damage caused by free radicals. Selenium also plays a role in the production of antibodies and helps regulate the immune response.
