According to research published by the National Institutes of Health, whey protein can maintain its stability for up to 19 months under ideal storage conditions. But the real question is, does protein powder lose its effectiveness over time, and what happens once the expiration date passes?

According to research on whey protein, the powder can last for up to 19 months under ideal storage conditions. However, once opened and over time, a chemical reaction can cause protein to degrade, causing a decrease in nutritional potency.
