Does Protein Powder Expire?

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'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.

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

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.
