The shelf life of a bottle of probiotics can vary depending on several factors, including the formulation, packaging, and storage conditions specified by the manufacturer. Probiotics are live microorganisms, and their viability can gradually decline over time, especially when not stored under the recommended conditions.
If the bottle of probiotics is not opened and not stored in the refrigerator, the expiration date provided on the packaging by the manufacturer is the most reliable indicator of its shelf life. This date is determined based on stability studies and the expected decline in the number of viable probiotic microorganisms over time.
Typically, probiotics that are not stored in the refrigerator may have a shelf life ranging from several months to a few years, depending on the product. It's important to check the expiration date on the packaging before using the product. After the expiration date has passed, the probiotics may lose potency, and their health benefits may be diminished.
To ensure the best results and to maximize the viability of the probiotic microorganisms, it is generally recommended to follow the storage instructions provided by the manufacturer, which often include storing the product in a cool, dry place or in the refrigerator, depending on the specific probiotic formulation. Additionally, once the bottle is opened, it's essential to use the product within the recommended time frame specified by the manufacturer to maintain the highest possible potency.
