How long does Casein Protein Powder last?

Casein protein powder can last a very long time, possibly up to a couple of years. However, referrer to the manufacturers expiry date for best results. While you may still be able to use casein protein powder for a while after its expiry date, the protein efficiency is greatly reduced and a fresh product should be sourced.

For best results, protein should be stored in an air-tight container, in a cool dark location. Don’t store your protein powder in the fridge or freezer as moisture is the biggest enemy of protein powder and condensation can form inside your container when you take it in and out of your fridge.
