The human body possess amazing defense mechanisms to protect itself against free radical damage. One mechanism consists of low molecular weight free radical scavengers (vitamin A, C, E and beta-carotene) and enzyme systems (superoxide dismutase, catalase and glutathione peroxidase) that keep free radicals in check and protect the body from oxidative damages.
Indeed, studies suggest antioxidant diet supplementation decreases oxidative stress, and may be useful to treat hypertension and to increase longevity. It is most likely that these favorable effects are mediated by an antioxidant-induced improvement of the immune function.
Vitamin C: An antioxidant that goes to work on the cellular level to protect against free radicals and to support cellular health. Vitamin C also supports the formation of collagen and improves skin antioxidant activity.
Vitamin B6: Is essential to the proper function of the immune system. It helps stimulate the immune response and activates the synthesis of antibodies.
Vitamin E: Naturally-occurring antioxidant that inactivates harmful free radicals.
Vitamin A: A phyto-nutrient that works as an antioxidant on the cellular level to promote immunity, and to protect DNA.
Zinc: An essential nutrient that works as a trigger for over 200 different enzymes and supports the number and function of several different immune cells.
Garlic, Lemon/Citrus Bioflavonoids: Both shown to increase immune function. And, citrus bioflavonoids work synergistically with vitamin C with each increasing the others effectiveness.
Copper, Selenium, Manganese, Magnesium: All minerals that support immunity.
