My father seems to have a mild issue with hoarding. He loves to buy things in bulk when they are on sale. Several years ago he bought two 5lb tubs of chocolate whey Protein powder. It has taken him all of these years to get through one tub. There is still one tub left but looking at the expiration, it expired in February 2011. Don't remember if it said "best by" or "use by".

I am scheduled for the sleeve on March 30, 2012. I have ordered powders and am getting everything arranged for my post-op diet. Do you guys think it would be okay to use the expired Protein Powder? Are the dates just a guideline for the freshest taste or does something gnarly happen after its past its date?

Thanks for any input!

If they were unopened, I don't think there's a problem, but if they've been open, I would worry about moisture getting in and mold growing. I had some individual packets of protein powders that were expired and I tried one and the flavor was just bad. It goes....stale...I guess.

Yes Protein powder should be discarded once it expires. Not only does it go stale but it also loses its potency, like anything else in our kitchens. Especially anything that expired last year, definitely do not use that.

Not only that your stomach will be healing and you don't want to chance any kind of bad food going in it. It will be sensitive enough. Good luck!

That's what I was thinking about it. I'm doing it in MX w/Aceves and want to limit the chance of having any out of pocket complications! I better just use fresh stuff and follow the diet to a T!

Oh thats awesome! You will love him/them... they're the best (imo but I'm biased I guess, ha!)

I am not normally a huge stickler about expiration or "best by" dates. Even bottled Water has an expiration date. Not that I keep things around that long on a regular basis, but I don't assume that something is spoiled or gross because it is a little past it's date.

However, with supplements, they can lose their potency. It would be terrible if you thought you were getting your Protein at this crucial time, and you were not. And, everyone is right, it would be tragic if the product was somehow spoiled and you caused injury to your post-operative stomach!

Just not worth it, IMO!
