In Sept '13 you answered a question on un-opened shelf life and the answer was a bit different than the answer given on Dec5 '13. It appears from that answer that a person could use if for a short time and then properly prepare it for long term storage for ANOTHER time. Is this correct? Also, I would imagine that the iodine resin would eventually become deactivated at some point...I bet it would be safer to say that after the first use, you should buy another. Thoughts on that?

It's my understanding that with proper back flushing and drying the filter will be good for unlimited storage... but hey, for the price, how cheap do we need to be. I have a few that I use on a regular basis and several in "permanent" storage (i.e. go bags). I have reused two of these on a regular basis for well over three months and still feel comfortable with their effectivity. However, I do not filter extremely turbid or dirty water. Such source water I prefilter and let settle before using the straw on them.

I've been using this bottle for close to 6 months or longer. Still as good as the day it was opened. I don't believe you'd have any trouble with a shelf life buying two.

It has a long shelf life if unopened. After opening it's recommended to refrigerate and use in three days. My experience when ordering from Amazon is expiration dates almost a year out.

My understanding is it depends on how it is stored. I wouldn't keep it more than 6 months. There seems to be an ordor about it. The company did not give anyinformation when I bought it and there is no information on the jar. Sorry I can't be more helpful.

My husband used this and the shelf life as far as I could tell was over a year because he only used a small amount. I suspect it is a very long shelf life.

Unmixed and dry I would imagine several years if kept cool and dry. If your taking this for the potassium Iodide in it I know packaged potassium iodide pills for radiation poisoning are good for 5-7 years in there packaging. Not sure about the other nutrients. I would keep a small bottle on the shelf and the rest in a mason jar or vacuum sealed bag like foodsaver bag in the fridge. Anything past a few years and it's potency will slowly degrade like most medications do. But in a shtf scenario we can't be picky and I would take it for 7 years.

I just received my jar and am looking at the storage directions now. "Best By 10/2014. Store in a cool, dry and dark place. Use within 3 months after opening or refrigerate." So what this says to me is that, unopened, it's best by October 2014 (10 months from now). Once opened, it should be used within 2-3 months if stored in a cabinet (someplace dark and cool), OR it can be refrigerated to last longer, although it doesn't specify by how much.

Same here. I used some at Christmas, and refrigerated the remaining container. Still fine. Based on similar products, as long as you keep it sealed and refrigerated after opening, it will last many months

Great question. There is no specific "shelf life" because nothing that allows the straw to work correctly stops working over time if the straw is not being used. If you do however use the straw, the life is determined by the type of water you draw through it. If you wish to do long term storage after a short use, you can follow the steps we provide you to clean and dry the filter. As long as it is properly prepared for long term storage it can then be stored indefinitely until it is needed again.

Great question. Iodine has a shelf life of approximately 1 year. The 3 months of doses is based on the recommended few drops a day which I don't do so my bottle doesn't last that long! :-)

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.

Yes and no. If you use it and do not empty the contents, you can use it again. However - there's no way of telling how much is left for another use. So since your life may depend on it, buy another container once you've used the first one. Just to be safe.

The oil is high in antioxidants and stores well in a cool dry place, about a year. Look at the expiration date, if you will get close to it or over by the time it will be spent, refrigerate now. Rule of thumb is you double remaining expiration time every 10 degC cooler than room for factory sealed foods. I recently had rotated a can of emergency refrigerated tuna exp. 2007 (rule of thumb extended it over 7yrs) and was delicious. If the oil will not be used for an extended period and you do have refrigeration room, why not extend the expiration and freshness by keeping it cooler?

I'm not sure if the date was on the package or stamped on the sryinge itself. I do know my dentist told me the shelf life is longer if you store it in the fridge. Between my wife and I we used it up before the date, so it wasn't a problem.

I have not had any go bad if it is unopened, but I found that it needs to be refrigerated after opening or it will grow mold on top. I would recommend using within 4 weeks of opening if it is kept refrigerated.

I was concerned about the same thing so I checked the La Prairie website for shelf life and expiration information. I found these statements in the FAQ section: Once opened how long will my product remain fresh? Please refer to the packaging of your product where you will see an illustration of a jar with a number on it. This is the period after opening date which conveys, in months, when the product is set to expire once it is opened. What is the shelf life of La Prairie products? As legally required, the shelf life of a finished product is 36 months. I have been using the product and would order it again. Hope this helps!

I have no knowledge based on scientific background - but logic suggests that if kept in a dry environment and is used within a season or two, it should not deteriorate. Also, it when opened there is no evidence of spoilage, bad smell, dried up discoloration, etc. it should be found. However, you can go on the Scott's web site and ask the question and get an expert answer.
