How do I find the expiration date for these tablets? I see some numbers embossed on the package but they are too small to really read.

It is on the cardboard wrapper in teeny tiny letters. Should be in large red letters on the cover as well as each individual wrapped tablet. Its dangerous not to have that info in an emergency. Mine says expires 11/2018.

I don't think those dates matter. I've spoken to service reps for Katadyn and for MSR. Both say that the tablets are viable for years, so I wouldn't worry about a printed expiration date. I've used Katadyn Micropur tablets for years--all within the US, from California to Maine. I've never had any problem. Even if the tablets get crushed, which is rare but it happens, they still can be used. The MSR tablets are the same formulation except each one of them will purify 2 liters of water, making them cheaper. I take both brand, simply because I stockpile the Katadyn (one liter) before the MSR came out. I don't think those dates matter. I've spoken to service reps for Katadyn and for MSR.

The numbers stamped in the foil are the expiration date. They can be hard to see. I find rolling them in the light works best.

In all honesty, chlorine dioxide, or brand names such as Clidox, is what we use in research to make sure things are very sterile after use. The dry salt form is extremely stable, but once you add it to water, or get it a little moist, then you have a countdown of effectiveness, so very important to keep dry. I would certainly wait the time they state so the chlorine diox breaks down and you don't end-up disinfecting your GI tract, creating other problems.

There was no expiration date on the 6 pack that I received. I guess you could look it up somewhere.

Look in the blue rectangle on the bottom of the box, the top line there is the expiration date. Each cartridge has a different date.

Well the expiration date on mines doesn't matter. I bought them last year, so yours should be different.

I don't remember seeing an expiration date on them, I never really paid attention.

I'm not sure I had to toss mine out after I got them. The expiration date was *Aug 2012*. Make sure you check the date!

The expiration date will vary according to the manufacturing date. The expiration date on the tabs that I last recieved is 4/19. It's possible that they will last far beyond the expiration date but who knows.

I cannot find an expiration date labeled as such. There is a string of numbers 012035112164 if it is code for a date I cannot tell.

I found no expiration date on the package. I used the previous package approx. 2 years with no notice of degraded performance.

I got my fish oil tablets about one month ago; the manufacture date was 01/2015 and expiration is two years or 01/2017. These work fine for me. Hope that helps.

I haven't looked for a date on the bottle, I assumed that these were of a current date. What I have noticed is that the coating on the tablet has changed. So maybe they are of the newer production line.

They had a year or more before they expired when i bought them last year. Iff the expiration date is not good they will take them right back and pay the shipping for you. That is why i order from amazon.

Mine says 2018. Keep in mind that expiration dates DO NOT mean that it's no good after that date. That's more like the "Guarantee" date. So it should still be good a year or two after that date. Beyond that it gets less potent, so it would still work 10 years from now "MAYBE" if you use TWO where it says to use one tablet. It's more of a "use at your own risk" at that point. I don't think they would ever be "Bad" to use after expiration, but may not help much...still better than nothing if your are in a bad situation.

Dear Judy,Yes. I have been using these tablets for several years; my drugstores no longer carry them, so I was happy that amazon does. In my current batch of tablets, they expired last month; however, I will continue to use them for 9 more weeks. My understanding is that the rule of thumb for pharmaceuticals such as this are actually good for 6 months beyond the expiration date. If you have not yet purchased them, you might want to buy only one box (12 weeks' supply.) You also might want to check with a pharmacist. Good luck! P.S. Another good brand is Ultrazyme. I think amazon carries it, and it may have a later expiration date. Dear Judy,Yes.

Hmm I just looked on my bottle but there is no expiration date to be found. Only a series of about 7 #s but they don't resemble a date.

Yes, there is a shelf life. The box I bought in May, 2013 has an expiration date of 02/2017. Since each tablet is foil wrapped, they should last that long.

The portable aqua tablets are good for 4 years unopened or 1 year once they are opened. You can find the manufactured date using the number on the label of the bottle as follows: The last 2 digits are an internal batch number that can be ignored. The remaining 3-4 digits are the month and year that the tablets were made. For example, if the number on the bottle is 121034, the tablets were made in December of 2010. Again, they are good for 4 years unopened, and 1 year once they are opened.
