Frequently Asked Questions
When should I start probiotics or enzymes to prevent travel stomach issues?
Start probiotics at least 7–14 days before travel if possible to allow strains to begin supporting your microbiome. If you only have a short window, take a shelf-stable spore probiotic the day before and during travel. Take digestive enzymes with meals that are heavy, fatty, or unfamiliar to reduce immediate digestive stress.
Do probiotics work on the first day of travel?
Some products (particularly spore-based or fermented preparations) can have quicker effects, but most probiotics need days to weeks to change microbiome composition. For same-day protection, use digestive enzymes, stick to safer food choices, and use rehydration/electrolyte support if you feel unwell.
Can a meal-replacement shake prevent holiday tummy troubles?
Yes — a clean, nutrient-dense meal shake or greens packet reduces exposure to unfamiliar or risky street food and provides enzymes and probiotics that aid digestion. Single-serve sachets make it easy to replace a meal when you’re unsure about food safety.
