So I got this supplements it’s called rep- cal , got both vitamin d and d3 but it’s expired back in October 2019. Any thoughts? Do I continue using it? I do hear that vitamin d can last forever but d3 will degenerate over time is it true??

Please share photos of what you have or check the labels. Vitamins do degrade over time. Plain calcium carbonate lasts forever.

Is your second container Rep Cal's plain (no D3) calcium or is it Rep Cal's multivitamin Herptivite?

How old is your leo? Are you interested in upgrading to Zoo Med's supplements? I think they are better.

how long have you had the supplements, and how have you stored them? (in detail)
vitamins will degrade over time like anything else, faster with exposure to moisture, heat, and light. if you got them recently or aren't sure of how they've been stored, the only safe thing is to toss them and replace soon.
if you've had them for a long time and always stored them properly, they could probably go months to maybe a year or more before they're actually "bad".

I'm a biochemist and I work in drug development; the expiration date is kind of an imaginary number in some ways. but in others it's critical. if you're not sure, just toss it but make sure whatever you buy has a nice long time before expiration and store it carefully.

I’ve had it for couple years now. And it “expired” just recently back in October. And no it’s not exposed to heat, sunlight or humidity. Expect for slightly higher room temp cuz of summer (I live in California) or colder in winter. But that’s about it

you can probably safely go over time then. but how long is a guessing game. as always, the safest bet is new stuff.
