Which supplements to take on a trip: to combat jet lag, support immunity, protect digestion. A compact yet complete kit.

Travel is stress for the body: time zone changes (jet lag), unfamiliar food, different water, crowded airports and planes (microbes!), dehydration during flights, lack of sleep. For athletes, this means an increased risk of injuries, illness and poor performance. Wisely chosen supplements can be the difference between a successful trip and a ruined season.
| Supplement | Purpose During Travel | Dose | When to Use? |
|---|---|---|---|
| Melatonin | Jet lag adjustment, falling asleep at the new time | 0.5-3 mg | 30 min. before the desired sleep time in the new location |
| Probiotics | Protection against traveler's diarrhea, digestion | 10-50 billion CFU | Daily, start 3 days before travel |
| Magnesium | Sleep, muscle relaxation, stress reduction | 300-400 mg | Before Sleep |
| Vitamin C | Strengthening immunity during travel | 1000-2000 mg/d. | Daily, especially on flight days |
| Electrolytes | Prevention of dehydration during flights | 1-2 servings | During the flight and after arrival |
| Zinc | Contributes to normal immune system function | 25-30 mg | Daily, start a week before travel |
Electrolytes during the flight (dehydration on the plane is high), melatonin upon arrival (according to local time), vitamin C + zinc against microbes in a crowded environment.
Probiotics (essential!) — start 3-5 days before travel, activated charcoal (for emergencies). Do not drink tap water, avoid ice in drinks.
All usual sports supplements (creatine, protein, beta-alanine), but note: in some countries certain supplements may be considered prohibited. Check!
Multivitamins (all in one), magnesium (for sleep in an unfamiliar bed), electrolytes (if you plan to exercise). As few separate bottles as possible.
