They are in sealed packages. I have had them for 1 year and they are still good.

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.

They don't have a marked expiration date. I buy a set ahead and store them for several months without problems. I take 6 to 8 months to use up a set and don't know that I've had any failures. I'm not sure how they would do if you store them for years.

I have bought new sealed ones that were dried out, so I don't think the shelf life is very long. Sorry to be the bearer of bad news.

Mine expire in May of 2015. I have used strips that were 5 years out of date but that were stored in warm and dry conditions. Their performance matched new strips that I also had on hand. Keep your strips warm and dry.

I've read that the shelf life is at least a year, most likely up to two if it is kept well sealed and in a relatively cool area. I've been impressed witht the packaging on BulkSupplemts products; they seal well and are not prone to ripping, so you should be good to have them sealed and in a cupboard for extended periods.

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.

They can last for several months if unopened. Longer if refrigerated prior to opening.

sometimes, I use 5-6 strips a week and have been ordering them for a while. Last time, I ordered , the expiration date was in less than 5 months. Please contact the seller before and ask about expiration date , if you plan to use everyday or go with 50 strips pack . Hope it helps.

It depends on the lot number of the seller. I've been buying from the Amazon suppliers for several years not and have never had an expiration problem. I always check the expiration date when I receive an order. I buy 90-100 strips at a time and I only test once a day, M-F, and occassionally on weekends. I've never went past the expiration on the orders I've received.

Hi Sean. You know that is an excellent question; I assume you are speaking to shelf life?. I actually do not know the answer to that. When I purchased mine, I used them right away and never looked to see any dates of expiration.

They were boxed quite well with tissue paper between each one, so I would think they should last for some time unopened or opened. They are also individually wrapped in plastic. They really are packaged well.

It is a good question, I ordered 100 strips one time (2 boxes) and they were only good for a month. Dumping about to be expired strips onto internet sales is a concern. I just checked and some of the companies guarantee an expiration date for the strips - just check to be sure. I got mine from Diabetes Health Supplies and it had a more than one year expiration and the company I just checked (Deep Discount Center) has a legal disclaimer saying that their strips have: EXPIRATION 6 MONTH AND FURTHER GUARANTEED. FREE SHIPPING NATIONWIDE. 90 DAYS NO QUESTION ASKED REFUND. MAY REPLACE WITH 2 (50 COUNT) BOXES. Hope this helps.

They usually are good for at least a year or more. I have never received any that were pass the expiration date. I've never seen where it says an expiration date when I order but if I got them and they were they would go back. I really don't think there will be a problem. I've never had any and I have been ordering them for at least 2 years through Amazon. Hope this helps.

I have purchased these in the past and obviously the expiration date changes with each shipment. However, I have always found there is plenty of time from time of purchase to expiration date. Some have been six months to others over a year.

You would have to contact the seller to find out what they currently have in stock for shipping. However, I would expect they would still continue to work for several months, minimum, after the expiration date. I would never consider throwing my extras away when they hit the expiration date.

For some reason, all the sellers want to avoid making promises about expiration dates, ... but the "200" pack that I bought, had over a year left on them.And frankly, ... I've used some that were 2 or 3 years "out of date", ... that still worked just fine, ... so I don't worry too much about dates, anymore.
