The probiotic bacteria in the gelatin stay alive and active for at least three weeks when kept refrigerated, ensuring the dose remains effective throughout the product's shelf life.

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
A systematic review would determine whether gelatin matrices consistently preserve probiotic viability across strains and storage conditions.
A systematic review and meta-analysis of all studies measuring viability of probiotics in gelatin matrices under refrigerated conditions, comparing strain-specific survival rates, pH, moisture content, and time to decay.
An RCT could test whether different storage durations affect clinical efficacy, but is not needed for viability alone.
A double-blind RCT comparing efficacy of L. fermentum UCO-979C gelatin distributed weekly (≤3 weeks old) versus biweekly (4–6 weeks old) in preventing H. pylori infection, with viability confirmed by plating.
A cross-sectional survey of commercial products could assess real-world viability under varied storage conditions.
A cross-sectional analysis of 50 commercially available L. fermentum UCO-979C gelatin samples from Chilean retailers, measuring viable counts at time of purchase under varying storage temperatures and durations.
Case reports could document failure due to poor storage, but cannot quantify viability.
A case series of 10 participants who consumed gelatin stored at room temperature and reported reduced efficacy, with post-consumption product testing for bacterial viability.
Expert opinion could speculate on viability based on similar matrices, but lacks empirical support.
