A special protein called interferon (a class of Cytokines) carries messages between cells and tissues. When a cell is infected with a virus, the cell releases interferons. Interferons alert other healthy cells to shield itself from this virus and request enzymes that destroy them. The killer enzyme is called T Cells or killer T Cells. Macrophages or white blood cells clean up the mess after the battle is over. Nutriferon is a supplement that helps your cells produce interferons to keep your immune system running optimally.

Immunity is a very important factor in staying healthy. The immune system consists of organs, tissues, cells, and chemicals that all work together in fighting off illnesses and diseases. The lymph nodes, thymus gland, spleen, tonsils, lymphocytes, antibodies, and interferon all aid this process. There are two types of immunity, innate and adaptive. Innate immunity is the fight against microorganisms in your body when you are fist born. Adaptive immunity is developed later in life from immunization or the result of fighting off an infection.

The immune systems classifies what is part of the body and what is not, identifies one invader from another, switches on search and destroy teams against invaders, switches off when danger passes, and remembers the enemies of the past.
