The immune system is an extremely complex system in our body. The nuts and bolts of it are: eat right, get enough sleep, and stay hydrated in order to keep your immune system healthy. If your immune system is healthy, you won't catch every cold and flu that you are exposed to.
If you feel the sniffles coming on or you are already sick, there are products such as BioGenesis PhytoImmune that will bump up the function of your immune system and get those white blood cells and antibodies moving to kick that cold out before it turns into anything else.
