How long does Whey Protein Powder last?

Whey protein powder lasts a good long time, possibly as long as a couple of years, but it should not be used once the manufacturers expiry date is exceeded. While it may be safe for a time after this date, the proteins efficiency has degraded such that a fresh product should be sourced. For best results you should store your whey protein powder in an air-tight container and in a dark cool location. Don’t store your protein in the fridge or freezer, as condensation can form inside the container when you take it out and open it. Moisture is the worst enemy of protein powder and causes it to spoil rapidly.
