What is the shelf life?

This, I cannot answer other than to say I have had mine over a year and they are still good. I keep them in a cabinet away from moisture and a fluctuation in heat or cold, with the bottle tightly sealed.

That I can't tell you - I bought these a couple years ago - Although they worked well, not sure of the shelf life - sorry!

No idea. Haven't tried that. I haven't had a problem with shelf life, though.

I'm not sure what the shelf life actually is, but I have had a bottle for 4-5 years, and it still works well.

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

I believe it has a shelf life of over one year, maybe more! ...that's my experience, works great each time.. I buy several each yr for my use.

The shelf life is well over a year. This is a product we are going to continue to stock. It does well for us.

no idea - i use it when i buy it. The product is very effective - the best I have found. Who cares about shelf life when you have the best product?

I am not sure the shelf life. I have been taking this one for two months. I can really REALLY tell a difference in my memory. I no longer have the 'fog' that comes with chronic fatigue. Huge difference that is greatly appreciated.

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.

Once opened the shelf life is six months to a year. You don't have to refrigerate after opening.

According to the package shelf life is one year. However, I have some a year past the expiration date and I'm still here!

I don't have an exact amount of time for its shelf life. But in my opinion, it lasts long enough to be satisfactory, whether in a drawer or whether it's been used to glue something. Nothing, as we know, lasts forever.

I'm sorry, I bought this a long time ago. I don't remember the shelf life. It was well sealed, so I doubt additional sealing would help.

I don't exactly know the shelf life because we use these flakes all the time and probably run out of them before they ever go bad. I have never had them go bad. We keep ours in the refrigerator as it is yeast, and perhaps that helps it stay fresh longer. This is a really great product. My guess would be that it could last at least 7 months.

I do not know the published shelf life, but I have used one year old product which worked just fine. You might want to check with manufactuor or review product data sheet.

I don't think there is a shelf life. I keep these in my garage in three-digit weather in the summer (Sacramento) and have not had any issues with spoiling or degradation due to the heat. There are a few left in the box and they have been through one summer and one winter so far with no issues.
