Do Immune System Boosters Really Work?

Q: Do immune system boosters like Airborne really work? I get sick a lot after flying, and it would be great to have some protection from all the bugs that get passed around on planes.

A: There is insufficient evidence to support claims that products such as Airborne or other “immune boosters” actually work. The best advice for preventing travel-related illnesses: eat a healthy diet when traveling, exercise, manage stress and wash your hands.

How about something simpler and healthier, such as balanced diet and physical exercises?
