Daily Immunity Booster has been like a member of our family since 1985. My wife and I are daily users of Daily Immunity Booster. Several of our children, now married, continue to take Daily Immunity Booster in their adult years. Initially, we were attracted to Daily Immunity Booster due to its unique quality of having been scientifically formulated and tested. We became life-time users because of the positive physical, mental and emotional benefits we experience on a daily basis.
