I use the same products. there is an expiry date on my containers. In all cases it looks to be about a year after I purchased it. however the store from which I bought them advised me that the expiry date is there because of canadian regulations and that I ought not to be overly worried about it, that the vitamins and such used in these products are often just already "expired" vitamins/minerals once meant for human consumption. I dont know how valid that comment is. I am going to just buy new when my containers expire, even though I likley will still have half of it left. Its not expensive to buy, so I'm going with "better safe than sorry".
