What is the shelf life of this? Does oxygen damage it?

Oxygen does gradually cause LOS to lose its potency so I keep mine tightly closed and inside a ziplock plastic bag. I don't know what the shelf life is supposed to be, but I have had my jar for at least 6 months, and it is still good.

I'm sorry I do not know the shelf life. But I don't recommend it as its fairly tasteless.

I have not had it stored very long, but can only guess that as long as the container cap is tightly closed it should last for years as long as temperature conditions are stable and not too warm. It is however a petroleum product and the effectiveness in some petroleum products can deteriorate even if never opened over many years. I apologize for this non-answer, if you plan on keeping it without use for a long time you should consult someone with expert knowledge, I just like how it works and don't know about it's intricate chemical properties.

I always refrigerate mine. Not sure what the shelf life is, as it doesn't last that long in our home.

It should be stored in the refrigerator or freezer. Not sure about the shelf life.

No date, it only goes bad once it's exposed to oxygen. Once it's out of the bottle , it starts oxidizing ...hince why you must wait 72 hours to wash.

Hi, shelf life is typically 1 year from time of purchase (but storing in colder places will help!)Thanks,Green Bulk team

Richard, I don't know about a shelf life. This stuff is so good that it is never around here long enough to know. It sure is an outstanding product.

I don't know the shelf life, but yes it needs to be refrigerated after openiing.

You can extend the storage if, as you use it, you change the container to keep the powder to empty space ratio low. The more oxygen the product is exposed to, the faster it will spoil. Additionally, I have had good experience in super extending the shelf life by vacuum sealing and freezing. I don't use much of this product per year- I use it as part of dehydrated meals for out bounding/section hiking- but I really like this product and it's sometimes hard to find in smaller sizes, so I've just figured out ways to keep it longer than average. Another easy way to keep it is to store it in a mason jar that's been spraypainted (outside only, of course) to block the light- big factors for storage of any dry powdered product are light(maintain color and nutrient value), oxygen (causes oxidation which leads to spoiling), and temperature (fluctuation and/or heat stress the molecular structure and can encourage bacterial growth, both of which lead to spoilage). Hope this helped. There's also a general expiration date on the base of the can but I've used the product well after the stamped date and have had no problems.

I agree completely with K.P. but because I only use mine for company it lasts a very long time. As long as it is stored air tight you'll have no problem! Enjoy!

Not sure on shelf life, but I've kept mine in the frig over a year and it is fine. Just make it is well sealed so it doesn't pick up other flavors. I have two fridges so I keep it with the beverages. Hope this helps some.

I have used it a year ago and have some in my cupboard but haven't used it since. Sorry, can't tell you about whether it's shelf life it a year and still good. I will likey try to use it this year. It is sealed so should be good.

I have kept it for 3 months now without any deterioration. I don't know the maximum shelf life.

4 Years is the shelf life. It is unaffected by opening it and using some. If it takes you 4 years to use this product, you clearly do not go outside enough. Some people use it as a back up and I would suggest using it in that last year and replacing it.

I'm sorry, but I don't know what the shelf life is. It looks exactly like granulated sugar so I would assume as long as it is kept in an air tight container it would last a rather long time. I use it for baking and it has taken me at least 4 months to use the 5 pounds. Have only good/great things to say about the product.

The supplier says it has a one year shelf life, officially, but is usually fine for a much longer period of time if kept in a cool, dry place. Make sure your seal is in tact upon arrival and if it isn't, let them know, they will replace it. There is no expiration date on the container that I have, though. They are very good at communicating in a timely manner, so if you contact them, you can expect a prompt reply and quick resolution to any concerns.
