Tag: Opened protein shake

According to food safety experts, an unrefrigerated homemade protein shake can safely last only about two hours at room temperature before bacterial growth becomes a concern. However, the rules are different for store-bought premade protein shakes, which are often designed to be shelf-stable until opened. So, do you put premade protein shakes in the fridge?

According to the product packaging and manufacturer instructions, Rockin Protein Builder, which is made with real milk, must be kept refrigerated. This requirement applies to both unopened and opened containers to ensure the product remains safe and fresh for consumption.
