You need to build your immune system on a cellular level daily so it is stronger and functions optimally-- not just help "boost" it. Why? It is likely that everyone, no matter what, will eventually be exposed. The very best, smartest, and safest thing you can do is focus on how you will weather the illness and recover when you are eventually exposed. Be prepared to fall down and need to stand back up, so to speak. Prevention is proactive, not reactive. What you can do it change the way your body responds to exposure so that your immune system has greater resilience. Build the strength to handle anything on a cellular level by taking IMMUSE Life.
