Maintaining Immune Health with Vitamins & Supplements

Written by Scientific Director and Pharmacist Jerry Hickey

The purpose of the immune system is to keep infectious microbes (such as dangerous bacteria, viruses, parasites and yeasts) out of the body, and to destroy any infectious microorganisms that do invade the body, hopefully before they have time to cause infection and disease.

The immune system is made up of a complex and vital network of cells and organs that protect the body from infection. Specialized immune system cells known as macrophages and neutrophils wrap around microbes, engulfing them in a special chamber. The chamber then floods with acids, dissolving the microbe. So, when you are diagnosed with an infection and are under attack by a microbe, the supplements in Table 1 may improve the immune systems ability to contain these organisms.

Good immune system function is a balance between regulation and activity. Sometimes, the immune system acts inappropriately identifying harmless substances such as a food or pollen, as an invading microbe and this is the essence of an allergy. Another scenario is that the immune system may mount a persistent but mismanaged attack and this is what occurs in arthritic pain or in asthma; individuals with these conditions should choose from the correct nutrients in Table 2 to assist their therapy.
