Question.

[Hugsy]

I hope I'm posting this in the right place. I have a jar of calcium powder. It has expired but is it still okay to use? Is it like most things where it's still okay just maybe not as effective?

I had a jar of expired calcium powder once and I still used it. However, as you said, it was not as effective and I had to increase the doses. My frogs didn't seem to become sick from the old powder, but I wouldn't use the expired powder for long.

I am pretty sure that it is the vitamin d part that expires. I would get new stuff. I know with people, expired vitamins can hurt more than help, not sure the reasoning though.

Calcium does not expire. Vitamins do though.
