To function well, our immune system depends on us taking good care of ourselves, for instance, getting enough rest, eating nutritious foods, drinking enough water and getting daily moderate exercise. But there are more ways to strengthen our immune system and keep us from being susceptible to the colds and flu bugs that are around at this time of year.

Taking a good multivitamin supplement daily is a good idea, plus Vitamin C is an excellent immune system booster, as is Vitamin D, which helps the body produce germ-killing proteins. Vitamin E is an antioxidant also and works well when taken in conjunction with Vitamin C.

Acetyl L-Carnitine seems to enhance the immune system and protect the body from oxidative stress.

Washing the hands frequently to get rid of germs limits the amount of work the immune system has to perform, so is a good habit to get into and laughter increases immune cells and infection fighting antibodies.

All in all, being good to ourselves is the best way to keep illness at bay.
