Tag: Pre mixed shakes

Research shows that while dry protein powder can last for years when stored properly, its shelf life drastically shortens once mixed with liquid. This means pre-mixing your protein shake requires careful consideration of storage and timing to ensure safety and quality.

According to researchers, protein powders can have a shelf life of up to 1.5 years when stored under ideal conditions. However, a critical question for many users is: can we store mass gainers in the fridge once the container is opened or the shake is mixed?

What matters more for most people is meeting their total daily protein intake rather than the precise timing.
