Do probiotics go bad? In the world of health supplements, probiotics have taken the spotlight. But, like any product, quality and safety matter.

This article cuts to the chase, examining the factors that can affect probiotic stability and shelf life. Let's uncover whether these beneficial microorganisms can indeed spoil over time.

Do Probiotics Go Bad?

Yes, probiotics can go bad.
