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.

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.

There are several supplements which keep your immune system healthy by balancing nutritional intake and warding off bacteria and viruses. Antioxidants, vitamin E, C, and A, selenium, zinc, beta-carotene, glutamine, probiotics, thymus extract, and DHEA can be taken as supplements to help insure a healthy immune system. Several herbs that also aid in warding off illness are Echinacea, andrographis, Asian ginseng, ashwagandha, cat’s claw, and green tea.
