I was wondering if anyone can tell me if protein power expire and how affect it would be if it does? I have a bottle but I can't seem to find an expire date on it. How long should I keep it before I throw it out?

    it does expire

    there should be an expiration date on it somewhere. i had to hunt to find the date on the tub that is on my desk, it was actually on the bottom.

    i don't think your doing to hurt yourself at all if you use it past the date tho... which is probably a year or even two after the manufacture date

    I don't know if it officially expires or not, but I have had some just taste really bad after an extended time on the shelf. But I doubt any of the nutrients will change.

    i've had an instance where a powder tasted funky.

    it was a post work out blend, not just protien, so there was a lot of sugar in it.

    i bought it at the vitamin shope and the woman suggested i shake the container vigorously. I did that and it tasted much better.

    i mix my own post workout drink and i'm very careful to mix ingredients in the propper proportions. when there is a powder with several different ingreidents, i dont know how you can really be sure you are getting them in the porportions outlined on the nutrition lable. I mean, i don't think each granual is a fusion of all the ingredients. this would apply less to straight protien though.

    So the taste might change but the effectiveness wont? It is still safe to consume if it has been sitting for a while. I don't think it has been a year yet.

    If it doesn't smell or taste bad, it's fine. (btw this applies to almost every food that "expires")

    I used some recently that had an expiry date for November 2013 and it's starting to smell funky now. Last one I had tasted sorta weird too.

    Most protein powders have a shelf life of up to 5 years. And even then it is likely safe to consume it for some time after that date. But if it smells or tastes rotten then it might not be a good idea to consume.
