According to one study, whey protein powder has a shelf life of at least 12 months under normal storage conditions. Knowing how do I know if my whey protein is bad is crucial for ensuring both the product's effectiveness and your personal safety, as expired or poorly stored powder can degrade in quality and potentially cause digestive issues.

According to accelerated shelf-life tests, unopened whey protein can maintain optimal quality for up to 19 months when stored correctly. However, improper storage can cause significant degradation, leading many to wonder exactly **what causes protein powder to go bad**.

Most sealed protein powders have a shelf life of up to two years, but improper storage can cause it to spoil early. Discover how to tell if protein powder is rancid by recognizing key sensory changes and protecting your health and investment before mixing your next shake.
