My husband has used them from end of winter the following winter and hasn't noticed any deterioration.

I don't know what the shelf life is, but I just received a 4pack in October with an expiration date of 12/15. Don't know what type of packaging.

I'm not sure what the shelf life is but the chemicals are in a capsule form so I would think as long as they are in cool, dry place they should last a reasonable amount of time.

I don't think there is a shelf life. I keep these in my garage in three-digit weather in the summer (Sacramento) and have not had any issues with spoiling or degradation due to the heat. There are a few left in the box and they have been through one summer and one winter so far with no issues.

As packaged they should last awile. If you open it to see what's in it, you might want to put it in the freezer. I'm extremely satisfied with my purchase and would recommend it to anyone.

Really good question! I got a pack out and looked, even used a magnifying glass. I cant find any expiration date. The last ones we ordered lasted several years before needed in an emergency. Sorry not much help!

I just checked my bottle and it has an expiration date of June 2016. I think I bought this current 2-pack back in November. As long as you take one a day and keep them dry, you are in no danger of letting them expire (unless of course you order more than just a 2-pack). Long story short, shelf-life from when you get it is probably 1.5-2 years.

Not sure about the shelf life, but I've had mine up to two years if stored in a cool dry place .. maybe even longer, asthey are sealed in plastic....

It depends on where you get them. I have gotten mine from Amazon and they have a shelf life of more than a year. Expiration date is printed on the bottom of the container.

I don't know for sure how long they last. You may need to check with the manufacturer, but as long as they stay sealed in the packaging so that they don't dry out, they should last a long time.

I don't see anything on the box or packs themselves, identified as "expiration date". There is a lot number on the box, that starts with 2020; not sure if that's the expiration date, or not. My personal experience is that they've lasted for years .. and until you asked, I never even thought of looking for an expiration date.

I am not sure the shelf life all raped up I would not trust to be more then 6 months. I know they don't last longh after you install them even if you don't print anyting.

Shelf life is 1 year. A bit longer if they are refrigerated. Great for storing in the bunker in case of a zombie apocalypse along with Spam and Twinkies. lol

I've had unopened ones sitting around for a month or so now, and they taste exactly the same as the fresher ones. Opened, I'd say you still have at least a couple of weeks. They seem to be a largely dehydrated product, so from my experience they seem unlikely to perish for a really long time.

They have the expiration date listed on the pack, which is typically between 1-2 years after purchase.

My assumption is they should last virtually forever, each package is sealed. I buy, and keep them for years.

It depends on the stock date of your seller... I ordered some early this year and the date on them is July 2015, so their shelf life is long. Hope this helps!!!!
