All of the calcium powder I buy has an experation date on it. I was wonder if they actually expire. This wouldnt be good cause i have been using the same stuff for years. any help will be apreciated.

I kind of doubt that calcium would expire, but I'm pretty sure that other supplements that are sometimes included- such as vitamins, will if you are using those types of products.
I'm sure somebody a little more in the know will drop in sooner or later to clarify the matter.

I have been using a bulk jug of Ca with D3 for over 2 years. I dont see an expiration date on mine. The only thing I know can make it go bad is repeated exposure to humidity.

Well, calcium carbonate should not expire, but as previously mentioned, it could get kinda icky after prolonged exposure to humidity. Living on an island, my stuff will turn clumpy after a few months, so I just buy smaller bottles so I don't waste half a bottle. Since calcium carbonate is virtually nonreactive, I doubt it can degrade.
In summation: the expiration date is probably just for the company's liability.


P.S. Calcium carbonate is a complicated way to say calcium dust. I just like using big, nerdy words.
