What is the Immune System?

The main function of your immune system is to protect you from external threats and keep you healthy. Think of your immune system as your body’s security team, trained to recognize and remove any threats while protecting your body’s peaceful residents. The first line of defense is to restrict the entry of unwanted foreign materials. The skin creates an excellent physical barrier but unwanted guests may still be inhaled or ingested. The acidity of stomach acid, mucosal membranes, and the presence of antibodies in saliva and tears all further help to prevent the entry of these substances into the body. The body’s second line of defense is the adaptive immune response, which includes antibody-antigen complex signals to other immune cells that this complex needs to be destroyed.

Do all immune support supplements work the same way?

Because the immune system is such a complex system, there is not a one-size-fits-all approach to supporting immune health. The various different types of white blood cells, immune proteins, and tissues and organs all have different nutrient requirements. Taking a single nutrient for immune health may assist in supporting one of these aspects of immune health, but if you are lacking other nutrients in your diet, then you may be falling short in getting total immune support.*
