An acidophilus drink is a probiotic beverage designed to support gut health through beneficial bacteria. Because these drinks contain live cultures, they are highly sensitive to temperature fluctuations and environmental exposure once the seal is broken. To maintain the viability of the active cultures and slow spoilage, continuous refrigeration is essential. You should monitor the liquid for changes in texture, an overly sharp sour aroma, or signs of secondary fermentation such as bubbling. Proper storage ensures you receive the intended probiotic benefits while avoiding the risks associated with over-ripened or spoiled dairy-based beverages.

Heads up: shelf-life ranges are estimates based on home storage. We make no guarantee of accuracy. When unsure, throw it out.
