Why does it say discard after 28 days upon opening of bottle? I thought it has long shelf life?

You know, I didn't notice that. Sorry. I still use mine. Maybe it's just because the ingredients may not be as strong or active after it has been opened or risk of getting an infection. I just find them soothing for my ears. They probably have to put some kind of expiration date on it. Hope this helps.

There's an expiration stamped on the bottle, but I use it all in about a month keeping it in my pantry. Some keep it in the refrigerator, but it's not needed.

Because it is preservative free and that is what the company recommends on its packaging. I, however, keep it in my fridge and have not had trouble keeping it over the expiration date, but I usually go through one bottle a month, so I don't have much experience with extended lengths of time.

I have had mine for more than a month and have been using it everyday. I still probably have at least a quarter of the bottle left

? I'm not sure I understand the question? Do you mean: Is there an expiration date on the bottle? Or: How long does it last? Please advise.

Excellent question - I wondered this myself. From what I know, the bottles are made to order because of their short shelf life. Once opened, they have a shelf life of 30-60 days. If not opened AND kept in a dark, dry atmosphere, I believe they're potency begins to breakdown after 6 months. Because of this, I do not buy more than one bottle at a time, but you can decide for yourself how fast you'd go through each bottle and buy accordingly. If anyone knows better or has other information, I invite them to reply to your question. You may also contact the manufacturer for their version of what the truth may be. Enjoy the product!

I don't know. I did not see a date on the container. Maybe a date is on the box it came in, but I throw the box away. I would guess this would last for several months or a year or more perhaps. I had a 3/4 gone bottle that I thought I left behind at a hotel and I opened a new one and used other stuff and a few months later found the bottle in my suitcase and it seemed to work the same.

It doesn't have a short shelf life, but I can't remember how long it is off the top of my head. Go to the manufacture's site and contact them.

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!

There is no expiration date on the bottle. It only says refrigerate after opening and use within 30 days. I hope this will be helpful.

3 years for an unopened bottle, however the active ingredients begin to degrade after 30 months. I would not used the product after 36 months in terms of expecting a positive result. Best Regards to you for the question.

We don't store this brand in refrigerator 2 bottles last us about 2 months. I have never had an issue with it.

Right or wrong, I just store it in my medicine cabinet. I wouldn't want to store it there for a year or more, but I get several months out of each bottle (4-6 drops a day). I never noticed that it got rancid or lost its effectiveness. Then again, I use it up, so it has never really had a chance to go bad.

It depends on when it was bottled. Ask the person selling it what it says on the bottom of the bottle. However, even though it has an expiration date it lasts longer then that. Hope that helps.

From my experience with this particular brand, once you open the spout you have a year at best, two years if you can tolerate some progressive degradation in its properties (thin viscosity becomes medium, then thick, then solid). I've also noticed that the less there remains in the bottle the quicker it degrades (due to air coming in at each subsequent use I would guess). I've stored unopened bottles in the fridge for over a year with good results, but once opened the clock is ticking.

It is because Amazon makes us put an expiration date on the bottle. However, our manufacturer puts on the date the product was made. These have at least a two year shelf-life. We are in the process of real time testing to determine that. We don't make false claims about expiration dates which is why we use date of manufacture. Many companies just randomly come up with expiration dates of three years out or more. We are being conservative at 2 yrs. As we get our stability testing back (real time), we will be updating the bottles from manufactured date to expiration date.

I really don't know. But I've had a bottle on the shelf unopened for as long as 2 years before I needed it, and it worked fine.
