I checked out the ingredients of that stuff. Could be the zinc. Some folks have reported positive results with supplementing zinc, especially for GI issues.
The other ingredients are all that hopus pocus stuff that's been magically diluted to the vibrations of the universe using their wizard tuning forks, including arsenic that's hopefully been diluted to 1 part per billion. Seriously, I think that's crap. So we'll go with the zinc for now. :-)
