A: Monpellerin probiotics are heat-resistant. Survival rates are: 4°C (refrigerator): 98.5% after 30 days, 86.6% after 240 days. 25°C (room temp): 96.7% after 30 days, 73.5% after 240 days. 45°C (extreme heat): 88.3% after 30 days, 69.6% after 240 days. For best results, refrigerate or freeze. If unavailable, buy one box at a time and use up within a month. We also offer free storage service—buy in bulk and we'll ship as needed.

A: The ideal storage temperature is around -18°C (freezer temperature). At this low temperature, the freeze-dried bacteria will remain in a dormant state for long-term preservation. Monpellerin probiotics are live cultures processed via freeze-drying. This process makes them resistant to freezing, so they won't clump or degrade in the freezer.

A: Yes. The cold temperature is immediately neutralized once the powder mixes with water or other liquids or enters into the mouth, so it won't affect your stomach.
