Should I eat expired protein powder?

This question comes up alot actually. Should you, or should you not, eat expired concentrated protein powder. Well there are things you should look for before eating up the sometimes expensive powders.
Does the powder have a best before stamp or an expiry stamp.
Some companies will label their product with a best before stamp. This sometimes means that it is still alright to eat, but may not have the same effect, such as it’s original great taste, or strong % of protein. This does not mean that the “Expires on” stamp actually means it has gone bad. In some places their are laws and regulations that make it so a product has a certain shelf life. Once this shelf life is over, the company will label it as the expiry date. The retailer then has to remove it from it’s shelves, but can still sell the product at discount prices from its stock room.
What to look for?
This is always tough, actually deciding if you should eat the powder or not. It is so expensive to just go out and purchase a new container, and its so tough to just throw away that bottle you told yourself you would use the last time you worked out! So what types of things can you look for? Well, I’ll say this now. If you have a product that has any types of dairy products, or anything that you think could become dangerous to digest, you obviously should not eat it! If you have just concentrated protein powder, then you should be ok. Look for anything like damage, or anything that suggests that there was tampering with the container. You do not want to eat bugs, or protein powder that has absorbed moisture over time!
If in doubt…
If you are in doubt. It doesn’t hurt to contact the manufacturer. Try giving them a call and seeing what they think. You could always talk to a professional at your local health store. It can never hurt to get more then one persons oppinion.

i have a mate who has bought bulk whey protein powder, like a huge bag of it. he used fuck all of it cos he stopped training, this was about 2 years ago. he mentioned to me that he had it there and that he would give it to me for nothing, theres so much there it would seem a waste to throw it out. its not like its a little container of it, its a huge bag full of the shit.
but cos its 2ish years old i dont know weather its ok to consume. i have looked at heaps of forums but who knows weather anyone of the people posting replys actually knows what there talking about.
does anyone know where there might be a source on the net where there is a studied fact that its ok to consume, or not? i cant find one anywere
thank you
