Tag: Refrigerating protein powder

Many people mistakenly believe protein powder requires refrigeration for freshness, but this is a common misconception. A study found that whey protein powder has a shelf life of at least 12 months under normal storage conditions, highlighting that moisture is the real enemy of your protein supplements.

Studies on whey protein show that improper storage at high temperatures and humidity can significantly shorten its shelf life, reducing it from over 18 months to just 9. Given this, many people wonder: Can I put my protein powder in the fridge to preserve its freshness?
