| If youâre planning a trip, you may be wondering whether complementary health approaches could help you avoid or manage travel-related problems such as jet lag, motion sickness, or travelersâ diarrhea. For jet lag, the dietary supplement melatonin may be helpful. Studies show that people who were given melatonin before air travel across time zones reported less jet lag than those who received a placebo (an inactive substance). Although several complementary approaches, including acupressure, magnets, and ginger, have been promoted as remedies for motion sickness, there isnât strong evidence that any of them are helpful.  The current evidence is insufficient to allow recommendations to be made about whether probiotics or other dietary supplements are helpful for travelers' diarrhea. |
