Jet Lag & Travel Recovery Protocol.
A supportive, adjunctive stack to ease circadian realignment across time zones and build travel resilience. It targets melatonin timing, evening relaxation, gut comfort, and stress load, and is not a treatment or cure for any sleep or medical condition.
The jet lag & travel recovery protocol in brief.
A quick summary. The full stack, with dose and timing for each supplement, is below.
The Jet Lag & Travel Recovery Protocol is a beginner stack of 6 supplements aimed at sleep: Melatonin, Magnesium Glycinate, L-Theanine, Vitamin C, Probiotics, and Ashwagandha. 3 are core and the rest are optional add-ons, at roughly $20-40/mo. Each supplement below lists its dose, timing, role, and the evidence behind it.
What is in the jet lag & travel recovery protocol.
Dose, timing, role, and evidence tier for each supplement. Core items carry the protocol; optional ones are situational. Open any name for the full profile.
| Supplement | Dose | Timing | Role | Evidence |
|---|---|---|---|---|
| Melatonin | 0.5-3 mg | 30 to 60 minutes before the target bedtime in the destination time zone | Core | Strong |
| Magnesium Glycinate | 200-350 mg elemental magnesium | Bedtime in the destination time zone | Core | Moderate |
| L-Theanine | 100-200 mg | Evening in the destination time zone, or during a flight to ease pre-sleep tension | Core | Moderate |
| Vitamin C | 500-1000 mg | Once daily with a meal, beginning a day or two before travel and continuing through the trip | Optional | Emerging |
| Probiotics | 5 to 20 billion CFU from a multi-strain product | Once daily, ideally started several days before departure and continued throughout travel | Optional | Emerging |
| Ashwagandha | 300-600 mg of a standardized root extract | Once daily with food, taken in the evening during the travel window | Optional | Emerging |
Melatonin is a hormone involved in circadian timing, and low to moderate doses taken near destination bedtime may help nudge the internal clock toward the new time zone. Lower doses are often as effective as higher ones with less reported morning grogginess.
Magnesium contributes to normal neuromuscular and nervous system function and is commonly used in the evening to support the wind-down before sleep. The glycinate form is generally well tolerated and may be less likely to cause loose stools than some other forms during travel.
L-Theanine is an amino acid found in tea that has been associated in some studies with increased alpha brain wave activity and a calm, relaxed state without strong sedation. It may help settle travel-related restlessness ahead of the new local bedtime, though sleep evidence is limited.
Vitamin C is an antioxidant that contributes to normal immune function, which may be helpful given the dehydration, crowding, and disrupted routines of air travel. Evidence for preventing travel illness specifically is limited, so any benefit is supportive rather than curative.
Probiotics may help support gut comfort and regularity when routines, diets, and time zones change during travel. Evidence on preventing travelers digestive upset is mixed and strain-specific, so any benefit is supportive and not guaranteed.
Ashwagandha is an adaptogenic herb studied for supporting the body's stress response and subjective relaxation, which may help with the heightened stress load of travel. It is supportive only and should not replace medical care for anxiety or sleep disorders.
How the pieces combine.
The mechanistic rationale for stacking these together rather than taking them in isolation.
- Take Melatonin and Magnesium Glycinate together at the destination bedtime: Melatonin supports circadian timing while Magnesium Glycinate supports evening relaxation.
- L-Theanine can be paired with Melatonin in the evening to ease pre-sleep restlessness. Because both may increase drowsiness, avoid combining them with alcohol or sleep medications during travel.
- Separate Probiotics from very hot drinks and, when possible, take them a couple of hours apart from any antibiotics so the live cultures are better preserved.
- Ashwagandha and L-Theanine both target the stress response, so introduce them one at a time before a trip to gauge tolerance rather than starting everything at once.
- Safety note: pregnant or breastfeeding travelers, anyone with a medical condition (including thyroid, autoimmune, or mood disorders), and those on prescription medication should consult a clinician before use, since Melatonin and Ashwagandha in particular can interact with medications and hormones.
- Do not operate a vehicle or perform tasks requiring full alertness after taking Melatonin, Magnesium Glycinate, L-Theanine, or Ashwagandha in the evening, as they may cause drowsiness.
