Room-temperature stability is product-specific
ODS notes that some probiotics require refrigeration while others can be stored at room temperature. That distinction prevents a single rule from covering all products. A brief exposure in a cool room and prolonged exposure in a hot vehicle are also different conditions. [1]
Returning it to the fridge does not establish the count
A viable count cannot be reconstructed by appearance, smell or a later return to cold storage. Ask the manufacturer whether the actual temperature and duration fall within its tested handling conditions. Without that information, an exact surviving CFU estimate would be invented. [1]
Record the details before deciding
Imagine a refrigerated parcel arrives warm. Note the delivery and storage circumstances, product and lot, and contact the seller or manufacturer for a product-specific answer. Do not double the amount to compensate for a guessed loss. The same review should distinguish product viability from whether the strains have relevant health evidence. [1]
| Example | Interpretation |
|---|---|
| Storage excursion | Needs temperature and duration |
| Normal appearance | Not a viable-count test |
| Extra capsules | Not a measured correction |
