How long does Vega protein last?

Could you elaborate on the shelf life and stability of Vega protein? I'm particularly interested in knowing how long it can be stored without losing its nutritional value or flavor. Are there any specific storage conditions that need to be met? Also, does Vega protein have a longer shelf life compared to other protein sources? If so, why is that? I'd appreciate a detailed response that considers these factors to help me make an informed decision about its purchase and usage.
