Frequently Asked Questions
Can I take probiotics on a plane?
Yes — probiotics are safe to take while flying. For best results bring a shelf-stable or spore-based formula (no refrigeration needed) and take as directed. If you’re trying a new product, start it several days before travel to confirm tolerance.
Do probiotics help prevent colds?
Certain probiotic strains are associated with supporting immune function, which may reduce the severity or duration of respiratory illnesses for some people. Look for clinically studied strains (like L. rhamnosus GG) and remember probiotics support overall immune health rather than guarantee prevention.
Do I need to refrigerate probiotic capsules?
Not always. Some formulas recommend refrigeration to maximize shelf life, while others are shelf-stable due to delayed-release or spore-based technology. Check the label; if you need a travel-friendly option, choose a product explicitly labeled as stable at room temperature.
