Once opened L-asorbic powder loses around 2% of its strength in a 6-8 month period. Although it still remains effective.

The expiration date is printed on the side of the container of vitamins. I just finished mine, I believe it was said to have expired this coming JULY.

I'm not too sure what the shelf life or storage recommendations are but the pills are individually sealed. I have eaten one well after a year of buying them and it was still good. I would assume just stire them at room temp. I did

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.

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.

The Synergy Company's peerless supplements & fruit/veg powders have a good long shelf life packaged in best light-protective & preserving dark glass vacuum sealed instead of less effective & toxic plastic. They told me the fruit/veg powders last several years kept cool & dry out of direct sunlight. Surprisingly my bottle has no expiration date stamped on it, but we use it up sooner than 2 years. If I found some old in the house, we'd still consume it knowing potency maybe reduced but since Vitamin C natural preservative I bet would take a really long time if ever to look/smell spoiled--likely over time just dessicate dry like potpourri.

Sorry I can't answer this question, I don't have the bottle any more. It is a powder so I'm guessing it should last a long time.

The amount of L-asorbic acid (Vitamin C) in this is 20%. I do believe they have others which have less a percentage of Vitamin C. Hope this is helpful.

The information on the label was designed to comply with FDA requirement for such product. Moreover this product typically retains its effectiveness upto two years when stored well. Mostly, they are used up within few weeks to months of production, so as important as expiry date is they may not be an issue with so many vitamin c serums.

I think the quality of this ascorbic acid/vitamin C powder is very good. High quality. Good purity. I haven't seen comparable vitamin c for cheaper. So I thought think this is very fairly priced. Only a very tiny amount is needed as you will see when you read the directions for mixing. Good luck with you serums.

I don't know the shelf life of this product and have used it for about 6 months ; however, I use it every day until the bottle is finished, which is in about 3 months. Its positive effect on my fatigue and/or memory is felt within 30-45 minutes.

The shelf life of Peak, whole milk powder is listed as two years unopened. I've had an open container for three months with no evidence of deterioration; the reconstituted product remains pleasing to eye and tastebuds for at least three days under refrigeration. I am well pleased with the product; it also mixes and dissolves nicely with water.

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.

Per their website on this product: "Our Vitamin C is derived from Sodium Ascorbyl Phosphate, which is a highly stable form of Vitamin C and does not oxidize for 24 months. We also make this serum freshly on a monthly basis. As long as the bottle is stored away from direct heat and sunlight, and the lid is kept tightly closed when not in use, then the serum should not oxidize for at least a year."

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.
