How effective are these enzymes (in the bottle) past the expiration date? I keep mine in the fridge - the expiration date seems to come up quickly.

The shelf life is now 18 months. We extended it beyond 12 month once we found the stability test passed at 18 months! We are now going for 24 months. We will be able to post 24 months only after testing it properly - and that is a really scientific test - waiting for 24 months and seeing how effective the lactase enzyme works ;)

I have conversed with the maker and they say that keeping it in the fridge will extend the life of the product. I haven't actually needed to keep using it past the date as our daughter drinks a lot of milk. I also take ours on vacations with us keeping it in my purse for handy use, then back into the fridge when we get home. It's always worked great for her.

I'm sorry I have not noticed; however, it has been my experience that most products like this are used long before their shelf life expires. You might try going to the eminence website for a more definite answer.

It's just what the other two people said. Look on the bottom of the bottle. It's different for every batch of product depending on when it was manufactured. The bottles I purchased from Amazon were good for well over a year. I put mine in the fridge door to possibly extend the shelf life past the expiration date.

Looks as if Robert answered your question on the expiration date, so I'll take the one on how long they're good for... virtually forever. I think the only reason they put expiration dates on something like this is to scare people into throwing away and replacing perfectly good products. I have some canisters that are many years past their "expiration" dates, and they still work fine.

There is an expiration date on the bottle if that is what you are wanting to know.

The don't put expirations dates on the bottle. They are good up to 3 years from the time you open the bottle.

I do not see an expiration date on my container, only a lot number. It doesn't say anything about product life. I will use the rest of the bottle I bought last summer this coming summer.

I wouldn't use it past the expiration date. Even though it's been refrigerated.

Hi Samantha, I'm not sure what the expiration dates are now, but when I bought mine, the expiration date was very close to the date I received them, meaning, the shelf life on my box was only like 2 months before the expiration date. That was just my experience though, you may get one that has a much longer shelf life, or you may have the same issue as I did. I had to use min quickly, because I dont have to test my glucose that often, so mine definitely would have expired, but if yourself or whoever they're for has to test more often then once a day, it's worth the price. I hope this was helpful. God bless.

Like the other poster said, my bottle was in the fridge for at least a year before I started using it, and I had already opened it. It was fine. So long as you keep it refrigerated it will last a very long time. I am guessing the acidity level and the fact that it is concentrated, is what helps keep this fresh.

I don't think there is a expiration date on the package. Just keep the yeast in the refrigerator for longer life, but do not freeze for this will damage the cell walls. I've keptyeast this way for well over a year.

You are right! I looked at my bottle and could not find an expiration date...I may purchase a different brand next time. Thanks for making me aware!

My bottle has a label that extends OVER a significant part of the rest of the label, where the exp. date most likely would be. See if this is the case for you. In addition, as has been mentioned, an exp. date is not critical for this product.

I have never bothered to look for the expiration date. I use up the product within 30 to 60 days so expiration has never been an issue.

If you store your Unizyme Enzymatic Lens cleaner in a climate-controlled environment (that is, inside your heated/air conditioned home), they should last just about indefinitely. If they were being stored for a long time in an unheated or humid warehouse, they might degrade relatively quickly.

Hi. I imagine each batch/bottle is different. Mine is 03/16. I keep them in the fridge although I don't think it's required.

Inspecting my bottle, there is no expiration date on it. I have stored new bottles for close to a year, and the quality was not effected.
