The immune system serves as the body's first line of defense against bacteria and other invading pathogens that might cause infection or disease. Everything the body is exposed to in the daily environment, including the foods consumed, the air we breathe and the water we drink contains germs. But a healthy immune system is able to deal with these bacteria before they can do major damage.

The stronger the immune system's ability to respond, the more healthy the body remains. Paying attention to immune support and taking supplements is crucial to maintaining a healthy body that can easily resist seasonal illnesses such as colds and flu, in addition to decreasing the risk of chronic disease.

A diet rich in fresh fruits and vegetables is a good start toward maintaining proper immune support. Many fresh fruits and vegetables contain powerful antioxidants that help prevent premature aging of the cells in addition to protecting cellular structure from oxidative damage caused by scavenging free radicals. Beta-carotene, Vitamin C and Vitamin E are essential for maintaining immune system health, either through the diet or obtained from daily supplements.

Zinc and selenium are also important for proper immune system functioning. First-milk colostrum, beta glucan, and olive leaf are all excellent nutrients for supporting the optimal functioning of the body's immune system. d-Limonene, a natural oil found in orange peel, also supports immune health.

Quercetin helps to stabilize immune system response and can prove helpful for providing increased immune support during times of added stress. Probiotics that help to promote a healthy balance of bacteria in the digestive tract are also very beneficial for supporting healthy ongoing immune system function because the health of the immune system is directly linked to the health of the digestive system.
