Probiotics: Preventing Complications of Antibiotic Use
What are probiotics? Shelf-Life of the Probiotic

Being a living organism, shelf-life of a probiotic is a concern. There is potential for degradation of the microorganisms to a point less than the labelling of the product and potentially below what is needed to be effective.

Because a probiotic may remain on the shelf for an extended period, despite being within the date of expiry, there remains a potential that the stability and viability may be compromised due to variations in temperature and other environmental conditions.

Storage under refrigeration may not be specified on the label of the product, but may be prudent to ensure viability up to the expiration date.
