Vitamin C

Vitamin C tops the list regarding immune boosters for many reasons. There has been more research about the immune boosting effects associated with Vitamin C than any nutrient. Vitamin C supplements tend to be inexpensive to produce, and it's available naturally in many fruits and veggies. Moreover, you can easily purchase a vitamin C fortified version of almost anything.

Vitamin E:

This very important antioxidant and immune booster does not get as much press as vitamin C, nonetheless it is critical to a healthy and balanced immune system . Vitamin E stimulates the production of natural killer cells that will look for and kill germs and other more dangerous types of cells. Vitamin E improves the production of B-cells, the immune cells which produce antibodies that eliminate bacteria. supplementation of Vitamin E might also reverse some of the decline in resistant response commonly observed in getting older.

Carotenoids:

Beta carotene improves the amount of infection fighting cells, natural killer cells, and helper T-cells, in addition to being a highly effective anti-oxidant that mops up excessive free radicals that hasten aging. Research has revealed that beta carotene can decrease the risk of cardiovascular problems, in particular strokes and cardiac arrest, giving medical credence to the belief that a daily carrot might keep a heart surgeon at a distance.

Bioflavenoids:

A array of phytonutrients named Bioflavenoids protect your body's cells from pollutants and thereby support the immune system. Microscopic parking spaces known as receptor sites exist along the membrane of each cell. Bioflavenoids fill these places and minimize toxic substances, pollutants, and bacteria from eating their way in to the cell tissue layer. Bioflavenoids likewise minimize cholesterol's potential to form plaques in blood vessels and reduce the development of tiny clots inside veins, which often can certainly lead to heart attack and stroke. A diet rich with six servings of fruits and vegetables will help you get the bioflavenoids needed to help your immune system work in top form.

Zinc:

While increasing the production of white blood cells that fight infection this essential mineral boost the immune system and helps the white blood cells fight more aggressively. Zinc helps white cells release more antibodies and also increases killer cells that fight against cancer. Zinc supplements have been shown to slow the growth of cancer. Zinc increases the number of infection-fighting T-cells, especially in elderly people who are often deficient in zinc, and whose immune system often weakens with age. There is controversial evidence that Zinc supplements may reduce the incidence of acute respiratory infections in infants and children. But again, this is controversial among researchers. Fortified cereals are the best source of zinc for infants and young children.
