A Simple, Travel‑Friendly Gut Health System for Flights, Jet Lag & International Travel

---

Travel can be tough on digestion. Long flights, unfamiliar foods, jet lag, stress, and disrupted sleep all place strain on your gut — often leading to bloating, constipation, diarrhea, fatigue, or lowered immunity.

Instead of relying on random supplements, this page outlines a simple, science‑driven BioOptimizers travel stack designed to support gut health before, during, and after travel.

This is the same system I recommend across my travel gut health guides.

Why Travel Disrupts Gut Health

---

When you travel — especially internationally — your digestive system faces multiple stressors at once:

• Changes in time zones and circadian rhythm
• Exposure to unfamiliar bacteria
• Dehydration during flights
• Increased stress hormones
• Heavier, unfamiliar meals

Together, these factors can weaken digestion and disrupt your gut microbiome. Supporting digestion, gut bacteria, and the gut–brain axis at the same time is key.

The BioOptimizers Travel Stack (3‑Supplement System)

---

This stack focuses on digestion, microbiome balance, and recovery — without overcomplicating your routine.

✈️ P3‑OM® — Probiotic Support for Travel Stress

Best for: Frequent flyers, long flights, international travel

P3‑OM® is a probiotic designed to survive harsh digestive conditions and support gut balance during periods of stress — including travel.

Why it’s ideal for travelers:

• Designed to survive stomach acid
• Supports microbiome balance under stress
• Shelf‑stable (no refrigeration needed)
• Easy to pack and take daily

How to use:

• Start 7–14 days before travel
• Take daily during your trip
• Continue for 1–2 weeks after returning

🍽️ MassZymes® — Digestive Enzymes for Unfamiliar Foods

Best for: Restaurant meals, foreign cuisine, bloating prevention

Digestive issues while traveling are often caused by poor digestion, not food poisoning. Stress and jet lag reduce stomach acid and enzyme production, making unfamiliar meals harder to break down.

MassZymes® provides a full‑spectrum enzyme blend to support efficient digestion.

Why it’s ideal for travel:

• Helps break down protein, fats, and carbohydrates
• Reduces bloating and heaviness after meals
• Useful for rich or unfamiliar foods

How to use:

• Take immediately before larger or unfamiliar meals

😴 Magnesium Breakthrough® — Jet Lag, Sleep & Stress Support

Best for: Jet lag, poor sleep, travel stress

The gut and nervous system are closely connected. Poor sleep and stress during travel can worsen digestion and immune function.

Magnesium Breakthrough® supports relaxation, sleep quality, and nervous system balance — all of which indirectly support gut health.

Why it’s ideal for travelers:

• Supports sleep during time‑zone changes
• Helps regulate stress response
• May support regular digestion via the gut–brain axis

How to use:

• Take in the evening during travel

➡️ Best for jet lag and travel recovery

How to Use the Travel Stack (Simple Routine)

---

Before travel (7–14 days):

• P3‑OM® daily

During travel:

• P3‑OM® daily
• MassZymes® before meals
• Magnesium Breakthrough® in the evening

After travel (1–2 weeks):

• Continue P3‑OM® to support microbiome recovery or try Microbiome Breakthrough to help repair Gut Lining

Who This Travel Stack Is Best For

---

This system is especially useful if you:

• Travel internationally
• Take frequent long‑haul flights
• Experience bloating, constipation, or loose stools while traveling
• Feel fatigued or unwell after trips
• Want a preventative approach to gut health

Why I Recommend a Stack Instead of a Single Supplement

---

Travel stresses the gut from multiple angles. Supporting just one area often isn’t enough.

Travel Challenge	Stack Support
Microbiome disruption	P3‑OM (Probiotic Breakthrough)®
Poor digestion	MassZymes®
Stress & jet lag	Magnesium Breakthrough®

Together, these supplements work synergistically to support digestion, resilience, and recovery.
