How does my immune system work?

The immune system’s job is to fight off invaders and protect you against infections and illness. (90) One of its main jobs is to recognize free radicals and eliminate them. Antioxidants fight free radicals, which are unstable molecules that cause damage to cells. Our bodies produce free radicals during normal cell metabolism, injury or when exposed to environmental triggers, such as tobacco smoke, sunlight and X-rays. (91) Many experts believe that free radicals may cause illness. Examples of antioxidants include vitamins A, C, and E, beta-carotene, lutein, lycopene, and the mineral selenium. (92)


What supplements may help support a healthy immune system?


Echinacea may work along with the body’s immune system to help keep you healthy. Echinacea may help reduce the symptoms and duration of colds and flu-like illnesses by quickly stimulating the body’s immune system. Newer studies show that echinacea works best when taken to prevent colds and flu. It can also be taken when symptoms first appear and then for seven to 10 days. It is not recommended for long-term use. If you want to try this for your child, you should first take to your pediatrician or pharmacist to make sure it is not dangerous and will not conflict with any traditional care your child receives.
