Do vitamin supplements for reptiles go off?

[dkir7979]

Hi everyone,
Does calcium go off?? also is it completely necessary to feed calcium and multivitamin?

Yes and Yes
Look at the bottom off the jar or on the label usually stamped on there somewhere.

What's the reptile in particular ?

Anyone got a rough idea how long they last before going off?
I have some Repti-Cal stuff that I've had for a while but there's no used by date on it that I can see.
It's got a "B" on the back but the label next to the B is just white with no date?

Edit: Are there any negative impacts on a Reptile if feed something covered in suppliment that has passed its used by date?

i was told the vitamins lose potency, the calcium stays the same but the added vitamin D3 wouldnt be working anymore.

yes, it is necessary to use calcium supplements, multivitamins can be replaced with a healthy diet.
